Best AI for Customer Service
The best AI customer service tools, ranked on independent evidence: Fin, Zendesk, Freshdesk, HubSpot Service Hub, Salesforce Agentforce, Sierra, Gorgias and Tidio compared on user ratings, analyst placements and published pricing, plus copilots, website chatbot builders, the real cost per resolution and the disclosure rules.
Quick answer: The best AI customer service agent for most businesses is Fin (formerly Intercom Fin), because it holds 4.5 out of 5 from 3,931 reviews on G2, it works on top of Zendesk, Salesforce, HubSpot or its own Intercom helpdesk, and it publishes a flat price of $0.99 per outcome. For a complete helpdesk with AI built in, Zendesk is the pick, because it is a Leader in the 2025 Gartner Magic Quadrant for the CRM Customer Engagement Center and includes 5 to 15 automated resolutions per agent a month, depending on the plan. Freshdesk is the best value at $19 per agent a month billed annually, and Gorgias is the best for Shopify stores. The caveat: every vendor counts a “resolution” differently, and a company is legally responsible for what its AI tells customers.
This page ranks software a business deploys to answer its own customers: AI agents that resolve support requests, helpdesks with AI built in, AI copilots for human support staff, and chatbot builders for a website. It is a different page from best AI chatbots, which ranks the assistants a person talks to, such as ChatGPT, Claude and Gemini, and also covers customer-service AI agents in less depth. Neighbouring pages go deeper on related software:
- Best AI CRM platforms ranks the CRMs that Salesforce Agentforce and HubSpot’s Customer Agent sit inside.
- Best AI for sales covers AI that sells, including Agentforce and HubSpot Breeze for sales teams.
- Best AI agents covers general-purpose AI agents and the benchmarks behind them.
- Best AI automation tools covers Zapier, Make and n8n for connecting a helpdesk to other systems.

Which one should you pick?
| If you need | Pick | Entry price with AI | Why |

The three kinds of AI customer service tool
“AI customer service” covers three different products, and most businesses need only one or two of them.
| Kind | What it does | Who answers the customer | Examples |
|---|---|---|---|
| AI agent | Reads the customer’s message, answers it and, when connected to other systems, takes actions such as a refund or an address change | The AI, with a handoff to a person when it cannot resolve | Fin, Sierra, Decagon, Ada |
| Helpdesk with AI | Ticketing, inbox, help centre and reporting, with an AI agent and an AI copilot built in | The AI first, then human agents in the same tool | Zendesk, Freshdesk, HubSpot Service Hub, Gorgias |
| AI copilot | Drafts replies, summarises tickets and suggests answers for a human agent | A person, assisted by AI | Zendesk Copilot, Freddy AI Copilot, Fin Copilot |
A fourth category, chatbot builders, lets a business build its own AI chatbot trained on its website and documents. Chatbot builders are cheaper and more flexible, but they lack ticketing and human handoff unless connected to a helpdesk (see chatbot builders).
The deciding question is where the support team works today. A team already on Zendesk, Salesforce or HubSpot pays least, in money and setup time, for the AI that vendor builds in, or for Fin, which plugs into all three.
What changed in AI customer service
Four changes reshaped the market.
Salesforce bought Fin. The company formerly called Intercom renamed itself Fin on 12 May 2026 (CX Today), and Salesforce agreed to acquire it for about $3.6 billion on 15 June 2026 (CNBC). Salesforce completed the acquisition on 10 September 2026, and says Fin “works seamlessly with the help desks and systems companies already use” (Salesforce). Intercom remains the name of Fin’s helpdesk product.
The helpdesks bought AI agent companies. Zendesk announced its acquisition of Forethought, an agentic customer-service start-up, on 11 March 2026 (TechCrunch), and completed it later that month (Zendesk). NiCE completed its $955 million acquisition of Cognigy on 8 September 2025 (Cognigy).
Pricing moved from seats to outcomes. Fin changed its billing unit from “resolution” to “outcome” on 12 March 2026 (Fin). Zendesk introduced three automated resolution tiers on 18 May 2026, of which only a “verified resolution” counts against the allowance (Zendesk). Sierra charges on outcomes rather than usage (Sierra).
Enterprise AI agent start-ups raised at multi-billion-dollar valuations. Sierra raised $950 million at a $15.8 billion valuation in May 2026 (Quartz). Decagon raised $250 million at a $4.5 billion valuation on 28 January 2026 (SiliconANGLE). Parloa raised $350 million at about $3 billion on 15 January 2026 (Tech.eu).
How we ranked AI customer service tools
A product is ranked only when it has independent evidence from outside the company: user ratings with real volume, an analyst evaluation, or both. Published pricing counts in a product’s favour, because a buyer can check it. Vendor resolution rates appear on the page labelled as vendor claims.
| Evidence | What it tells you | Where it comes from |
|---|---|---|
| User ratings with volume | How support teams rate a product over time | G2 and Capterra |
| Analyst evaluations | How analysts place a vendor against its competitors | Gartner Magic Quadrants (2025 and 2026); Forrester Wave (Q2 2026) |
| Customer and leader surveys | What customers accept from AI, and what service leaders report | Gartner press releases |
| Published pricing | What one AI resolution costs | Vendor pricing pages; third-party figures labelled as such |
| Vendor claims | Resolution rates and customer counts | Vendor sites and announcements, labelled as claims |
Two limits apply. First, no independent, audited measurement of real-world AI resolution rates exists across vendors, so no vendor’s resolution rate can be compared with another’s. Second, the open benchmarks for customer-service agents were built by vendors: Sierra created τ-bench, and Salesforce AI Research created CRMArena-Pro. Both measure the underlying models rather than finished products.
Best AI customer service tools ranked
| Rank | Tool | Kind | Best for | Price with AI | Independent evidence |
|---|---|---|---|---|---|
| 1 | Fin | AI agent (plus Intercom helpdesk) | Best AI customer service agent overall | $0.99 per outcome; Intercom seats from $29 a month | G2 4.5 (3,931); Capterra 4.5 (1,132); Forrester Strong Performer (as Intercom) |
| 2 | Zendesk | Helpdesk with AI | Best AI helpdesk | From $55 per agent a month (annual); extra resolutions $1.50–$2.00 | Gartner Leader (2025); G2 4.3 (7,102); Capterra 4.4 (4,094) |
| 3 | Freshdesk | Helpdesk with AI | Best value helpdesk | From $19 per agent a month (annual); $49 per 100 AI sessions | G2 4.4 (3,820); Capterra 4.5 (3,494); Gartner Niche Player (2025) |
| 4 | HubSpot Service Hub | Helpdesk with AI, inside a CRM | Best for HubSpot users | Professional $90 per seat a month (annual); about $0.50 per resolution | G2 4.4 (3,018); Capterra 4.4 (193) |
| 5 | Salesforce Agentforce | AI agents inside a CRM | Best for Salesforce enterprises | $2 per conversation, or Flex Credits | Gartner Leader (CEC 2025; Conversational AI 2026); G2 4.4 (8,462); Capterra 4.5 (832) |
| 6 | Sierra | AI agent | Best for large enterprises | Quote only; outcome-based | Forrester Strong Performer (Q2 2026); G2 4.5 (131) |
| 7 | Gorgias | Helpdesk with AI, for ecommerce | Best for Shopify stores | $0.90 per resolved interaction | G2 4.6 (582); Capterra 4.6 (135) |
| 8 | Tidio | Live chat with an AI agent | Best for small business websites | Lyro from $32.50 a month for 50 conversations | G2 4.6 (1,967); Capterra 4.7 (590) |
The best AI customer service tools, reviewed
1. Fin: best AI customer service agent overall
Price: $0.99 per outcome, with a 50-outcome monthly minimum and no platform fee; with the Intercom helpdesk, $0.99 per outcome plus helpdesk seats from $29 a month; 14-day free trial (Fin) Owner: Salesforce, since 10 September 2026 (Salesforce) Independent evidence: 4.5 out of 5 from 3,931 reviews on G2; 4.5 out of 5 from 1,132 reviews on Capterra; Intercom is a Strong Performer in the Forrester Wave for Conversational AI Platforms for Customer Service, Q2 2026 (CX Foundation)
Fin is the AI agent with the most user reviews and the clearest published price among the dedicated AI agents. Sierra, Decagon and Ada publish no prices.
Fin charges per outcome, a unit it introduced on 12 March 2026 in place of “resolution”. A resolution, a procedure handoff, a disqualification and a self-serve routing each cost $0.99, a sales qualification costs $9.99, and a conversation handed to a person without an outcome costs nothing, according to Fin’s pricing page. Fin works on top of Zendesk, Salesforce, HubSpot and other helpdesks, as well as on Intercom’s own helpdesk.
Fin covers voice, email, live chat, Slack, WhatsApp, SMS, Instagram and Facebook Messenger, according to Fin. Fin Voice is priced on request. Salesforce says Fin serves more than 30,000 companies and reports a 76% average resolution rate; the release does not explain how resolution is measured, so the 76% is a vendor claim.
Limitations: The 50-outcome monthly minimum and “minimum commitments” mean Fin is not pay-as-you-go from zero. Fin’s own help centre describes a $49 monthly base that includes 50 resolutions (Fin help centre), while the pricing page states a 50-outcome minimum with no platform fee, so a buyer should confirm the structure in the quote. Salesforce ownership is new; buyers on competing CRMs should ask how long Fin’s support for other helpdesks is guaranteed, because the closing release does not name any helpdesk.
Best for: Support teams that want a strong AI agent without changing helpdesk, and that want a price they can model per conversation.
2. Zendesk: best AI helpdesk
Price: Support Team $19 per agent a month billed annually ($25 monthly), without the full suite; Suite Team $55 ($69 monthly); Suite Professional $115 ($149 monthly); Suite Enterprise on request; extra automated resolutions $1.50 each committed or $2.00 pay-as-you-go; Copilot $50 per agent a month billed annually; 14-day trial (Zendesk) Independent evidence: Leader in the 2025 Gartner Magic Quadrant for the CRM Customer Engagement Center (CX Today); 4.3 out of 5 from 7,102 reviews on G2; 4.4 out of 5 from 4,094 reviews on Capterra
Zendesk is the only dedicated helpdesk among the five Leaders in Gartner’s 2025 Magic Quadrant for the CRM Customer Engagement Center; the other four are Salesforce, Microsoft, ServiceNow and Oracle. It also has the second-largest G2 review base on this page.
Zendesk includes AI agents on every Suite and Support plan. Each plan includes automated resolutions per agent per month: 5 on Team, 10 on Professional and 15 on Enterprise, capped at 10,000 a year, according to Zendesk’s help centre. An automated resolution is a request resolved without escalation and confirmed by a large language model check. Since 18 May 2026 Zendesk sorts outcomes into three tiers (assisted escalation, contained resolution and verified resolution), and only verified resolutions count against the allowance.
Zendesk bought Forethought in March 2026, which adds multi-agent automation to its AI agents. Its Resolution Platform, launched in March 2025, combines AI agents, a knowledge graph, actions in other systems and quality measurement (Zendesk).
Limitations: Zendesk’s G2 rating, 4.3, is the lowest of the ranked tools. The included resolutions are small for a high-volume team: a 10-agent team on Suite Professional gets 100 a month. Copilot is licensed across the whole account, not per agent (Zendesk). Admins must choose whether to allow overage, pause the AI agent or cap monthly resolutions.
Best for: Mid-size and large support teams that want ticketing, a help centre, AI agents and a copilot from one vendor.
3. Freshdesk: best value AI helpdesk
Price: Growth $19 per agent a month, Pro $55 and Enterprise $89, all billed annually; Freddy AI Agent includes 500 sessions once per account, then $49 per 100 sessions; Freddy AI Copilot $29 per agent a month on Pro and Enterprise; 14-day trial of Enterprise (Freshworks) Independent evidence: 4.4 out of 5 from 3,820 reviews on G2; 4.5 out of 5 from 3,494 reviews on Capterra; Niche Player in the 2025 Gartner Magic Quadrant for the CRM Customer Engagement Center
Freshdesk is the cheapest full helpdesk on this page with an AI agent included on every plan, and it holds higher user ratings than Zendesk on both G2 and Capterra.
Freddy AI Agent costs $0.49 a session after the included 500. A session is not the same unit as a Zendesk resolution or a Fin outcome, so the per-unit prices cannot be compared directly (see what AI customer service really costs). The 500 included sessions are a one-time allowance per account, not a monthly quota, according to Freshworks’ pricing FAQ.
Limitations: Gartner places Freshworks as a Niche Player rather than a Leader. The 500 included AI sessions do not renew, so a team answering 500 AI conversations a month pays $245 a month for sessions from the second month. The copilot is not available on Growth. Freshworks’ pricing page lists no free plan.
Best for: Small and mid-size support teams that want a full helpdesk with AI for the lowest seat price.
4. HubSpot Service Hub: best for HubSpot users
Price: Free for up to 2 users; Starter from $7 per seat a month; Professional $90 per seat a month billed annually ($100 monthly) with a $1,500 onboarding fee; Enterprise $150 per seat a month with a $3,500 onboarding fee; extra HubSpot credits $0.01 each (HubSpot) Independent evidence: 4.4 out of 5 from 3,018 reviews on G2; 4.4 out of 5 from 193 reviews on Capterra
HubSpot Service Hub puts support tickets, the AI agent and the CRM record in one place. Its Customer Agent is available on Professional and Enterprise plans of any HubSpot hub, and uses credits only when it resolves a conversation, according to HubSpot.
HubSpot prices the Customer Agent at $0.50 per resolution (50 HubSpot credits), where a resolution means the agent answered and the conversation was not handed to a person for 72 hours (HubSpot). HubSpot reported on its first-quarter 2026 earnings call that the Customer Agent resolves 70% of conversations, up from 20% a year earlier, and had passed 9,000 customers (CX Today); HubSpot does not publish how it defines a resolution, so the 70% is a vendor claim.
Limitations: The Customer Agent requires Professional or Enterprise, so the cheapest route to it is $90 a seat a month plus $1,500 onboarding, according to HubSpot. Capterra’s review base is small, at 193. Credits reset monthly and do not roll over.
Best for: Businesses that already run sales or marketing on HubSpot and want support on the same customer record. HubSpot’s CRM is compared on best AI CRM platforms.
5. Salesforce Agentforce: best for Salesforce enterprises
Price: $2 per conversation, or Flex Credits at $500 per 100,000 credits, where a standard action uses 20 credits (about $0.10); Agentforce Service add-on $125 per user a month for employee use; Agentforce 1 editions from $550 per user a month (Salesforce) Independent evidence: Leader in the 2025 Gartner Magic Quadrant for the CRM Customer Engagement Center; Leader in the 2026 Gartner Magic Quadrant for Conversational AI Platforms (Salesforce); 4.4 out of 5 from 8,462 reviews on G2; 4.5 out of 5 from 832 reviews on Capterra
Salesforce Agentforce is the only product on this page that is a Leader in both Gartner Magic Quadrants that cover AI customer service, and Agentforce Service has the largest G2 review base on the page.
Agentforce prices customer-facing AI in two ways that cannot be mixed in one Salesforce org: $2 per conversation, or Flex Credits charged per action. Salesforce’s pricing page charges 20 Flex Credits for a standard action and 30 for an Agentforce Voice action. At Dreamforce on 28 September 2026 Salesforce listed Fin as a ready-made service agent that connects to a Salesforce org, and made Agentforce Voice generally available in six more languages (Salesforce).
Limitations: The real cost of Agentforce depends on how many actions each conversation triggers, which is hard to forecast before deployment. Salesforce’s G2 listing combines Agentforce Service with Service Cloud, so the rating reflects the helpdesk as much as the AI agent. Agentforce suits an organisation with Salesforce administrators; it is not a self-serve tool for a small team.
Best for: Organisations already running Service Cloud that want AI agents on the same data and permissions. Agentforce for selling is covered on best AI for sales.
6. Sierra: best for large enterprises
Price: Quote only; Sierra charges on outcomes rather than usage (Sierra) Independent evidence: Strong Performer in the Forrester Wave for Conversational AI Platforms for Customer Service, Q2 2026 (CX Foundation); 4.5 out of 5 from 131 reviews on G2
Sierra builds custom AI agents for large companies and is paid when its agents achieve an agreed outcome. Sierra, co-founded by Bret Taylor and Clay Bavor, raised $950 million at a $15.8 billion valuation on 4 May 2026, and has said it passed $150 million in annual recurring revenue (Sierra).
Voice is a core channel: at its 2026 Summit, Sierra announced Tandem Voice, which keeps a voice agent talking while a separate reasoning layer works, its own Curie and Fleming models, and a Stripe integration for taking payments mid-conversation (Sierra).
Limitations: Sierra publishes no prices, so its cost cannot be compared before a sales process. Its G2 review base, at 131, is small next to the helpdesks. Sierra is an enterprise product; it is not designed for a small team to set up alone.
Best for: Large consumer brands with high support volumes that want a custom agent built with the vendor and paid on results.
7. Gorgias: best for Shopify stores
Price: AI Agent $0.90 per automated interaction on annual contracts and $1.00 on monthly; helpdesk plans are priced by ticket volume, from Starter at $10 a month for 50 tickets to Advanced at $750 a month billed annually for 5,000 tickets (Gorgias) Independent evidence: 4.6 out of 5 from 582 reviews on G2; 4.6 out of 5 from 135 reviews on Capterra
Gorgias is a helpdesk built for online shops, with order data from Shopify and other ecommerce platforms shown beside each ticket. Its AI Agent answers order-status, return and product questions, and Gorgias also sells a Shopping Assistant that recommends products.
Gorgias says its helpdesk is never priced per agent; it prices by ticket volume instead, and each AI Agent interaction also counts as a ticket. AI Agent overage costs $1.50 per interaction for Support plus Shopping Assistant, and $0.83 to $2.00 for support only, depending on tier and billing period (Gorgias).
Limitations: Gorgias is built for ecommerce and fits poorly outside it. Ticket-based pricing means a sudden spike in volume raises the bill. Its review base, 582 on G2, is smaller than the general helpdesks’.
Best for: Shopify and other ecommerce stores where most questions are about orders, returns and products.
8. Tidio: best for small business websites
Price: Free with 50 conversations a month and 50 Lyro conversations in total; Starter $24.17 a month; Growth from $49.17 a month; Lyro AI Agent add-on from $32.50 a month for 50 conversations, up to 1,000 a month self-serve; 7-day trial, no card required (Tidio) Independent evidence: 4.6 out of 5 from 1,967 reviews on G2; 4.7 out of 5 from 590 reviews on Capterra
Tidio is a live chat tool for small business websites with an AI agent, Lyro, that answers from the business’s own help content. Tidio holds the highest Capterra rating of the ranked tools, at 4.7.
Tidio says it uses Claude from Anthropic and its own in-house models to power Lyro (Tidio). Tidio claims a 75% average resolution rate for Lyro, without a published method, so the figure is a vendor claim.
Limitations: Tidio is a chat-first tool; it is not a full email and ticketing helpdesk on the scale of Zendesk or Freshdesk. Lyro allowances are small on the self-serve plans, and Tidio’s pricing page does not state whether the displayed prices are annual or monthly rates. The free plan’s 50 Lyro conversations are a one-off allowance, not monthly.
Best for: Small online businesses that want an AI chat widget on their website for the price of a software subscription.
Other AI customer service tools worth knowing (not ranked)
These tools are real and available today. They are not ranked because their independent evidence is thin (few user reviews) or because they are sold only through enterprise sales with no published price. Descriptions are the vendors’ own unless stated.

AI chatbot builders for a website
A chatbot builder trains an AI chatbot on a business’s website, help articles and documents, and puts it on the website as a chat widget. Builders cost less to start than a helpdesk and give more control over how the bot behaves, but most lack ticketing, so conversations the bot cannot answer need a route to a person.
| Builder | Best for | Price | Independent evidence |
|---|---|---|---|
| Tidio | A ready-made AI chat widget with live chat for a small business | Lyro from $32.50 a month for 50 conversations | G2 4.6 (1,967) |
| Chatbase | A quick chatbot trained on website content | Hobby $40 a month, or $32 billed annually (Chatbase) | G2 4.8 (46); Capterra 4.3 (73) |
| Botpress | Developers who want control over logic and integrations | Free with 100 conversations; Plus $150 a month for 250 conversations; Team $750 for 1,500 (new workspaces since 14 May 2026) | G2 4.5 (514); Capterra 4.5 (37) |
| Voiceflow | Designing chat and voice agents visually, as a team | Quote for businesses; free trial for agencies (Voiceflow) | G2 4.5 (115) |
Best AI chatbot for a website: Tidio for a small business that wants live chat and an AI agent in one widget, because it has the largest review base of the four and a free plan. Botpress is the better choice for a developer building a custom bot, because AI usage is bundled into its conversation pricing since May 2026.
AI copilots: AI that helps human agents
An AI copilot drafts replies, summarises long tickets and suggests help articles for a human agent, who decides what the customer sees. The strongest independent evidence for AI in customer service is for copilots, not for autonomous agents.
A study of 5,179 customer support agents by Erik Brynjolfsson, Danielle Li and Lindsey Raymond found that an AI assistant raised the number of issues resolved per hour by 14% on average and by 34% for novice agents, with minimal effect on the most experienced agents (NBER working paper 31161, published in the Quarterly Journal of Economics in 2025).
| Copilot | Price | Plans | Source |
|---|---|---|---|
| Zendesk Copilot | $50 per agent a month billed annually, account-wide | Suite Professional and above | Zendesk |
| Freddy AI Copilot | $29 per agent a month | Freshdesk Pro and Enterprise | Freshworks |
| Fin Copilot | $35 per user a month | Salesforce only, according to Fin’s FAQ | Fin |
| Front Copilot | $20 a seat a month; included on Enterprise | Front Starter and Professional | Front |
| HubSpot Breeze | Included, metered in HubSpot credits | Service Hub | HubSpot |
What AI customer service really costs
Every vendor bills a different unit, so the per-unit prices are not directly comparable. A Fin outcome includes some handoffs; a Zendesk automated resolution counts only verified resolutions since May 2026; a Freshdesk session and a Salesforce conversation are charged whether or not the customer’s problem is solved.
| Tool | Unit billed | Price per unit | AI cost for 1,000 units a month | Plus |
|---|---|---|---|---|
| Fin | Outcome | $0.99 | $990 | Helpdesk seats, or nothing if Fin sits on your existing helpdesk |
| Zendesk | Verified automated resolution | $1.50 committed; $2.00 pay-as-you-go | $1,350 committed for a 10-agent Suite Professional team (100 included) | Seats: 10 × $115 = $1,150 a month |
| Freshdesk | Session | $0.49 after the first 500 | $490 | Seats from $19 per agent |
| HubSpot Service Hub | Resolution (50 credits) | $0.50 | $500, before included credits | Professional seats at $90, plus $1,500 onboarding |
| Salesforce Agentforce | Conversation | $2.00 | $2,000 | Salesforce licences |
| Gorgias | Automated interaction | $0.90 annual; $1.00 monthly | $900 | Helpdesk plan by ticket volume |
| Help Scout | Resolution | $0.75 | $750 | Seats from $25 per user |
| Google CX Agent Studio | Session | $0.50 | $500 | Development and integration |
The comparison that matters is cost per resolved customer problem against cost per human-handled ticket. Gartner predicts that by 2030 the cost per resolution for generative AI will exceed $3, higher than many offshore human agents (Gartner).
What the independent evidence says
Customers remain wary of AI in customer service, and service leaders are keeping their human teams.
| Finding | Figure | Source |
|---|---|---|
| Customers who say a company using generative AI for service must provide access to a human | 87% | Gartner (3,566 customers) |
| Customers who would try a chatbot again after a bad experience | 27% | Gartner (3,566 customers) |
| Customers who used a company chatbot in their most recent service interaction | 7%, against 49% who would have used one if offered | Gartner (same survey) |
| Service leaders under executive pressure to implement AI in 2026 | 91% | Gartner (321 leaders) |
| Service leaders who have reduced agent headcount because of AI | 20% | Gartner |
| Customer issues fully resolved in self-service | 14% | Gartner |
Gartner predicts that agentic AI will resolve 80% of common customer service issues without human intervention by 2029 (Gartner). Gartner also predicts that by 2027 half of the companies that cut customer service staff because of AI will rehire for similar work under different job titles (Gartner).
Vendor resolution claims, side by side. These figures are the vendors’ own and use different definitions, so they are not comparable with each other or with Gartner’s 14%.
| Vendor | Claimed resolution rate | Source |
|---|---|---|
| Fin | 76% average | Salesforce |
| Tidio Lyro | 75% average | Tidio |

Gartner has no Magic Quadrant specifically for AI agents for customer service; “AI Agents for Customer Service and Support” exists only as a Gartner Peer Insights review category.
When AI customer service goes wrong
Three public cases show the risks a business takes on when an AI answers its customers.
A company is liable for what its chatbot says. In Moffatt v. Air Canada (2024 BCCRT 149), British Columbia’s Civil Resolution Tribunal held Air Canada liable for negligent misrepresentation after its website chatbot gave a customer wrong information about bereavement fares. The tribunal rejected the argument that the chatbot was responsible for its own statements and ordered Air Canada to pay C$812.02 in damages, interest and fees in February 2024 (McCarthy Tétrault).
AI agents can invent policies. In April 2025, an AI support agent for the coding tool Cursor told a user that the subscription was limited to one device as a “core security feature”, a policy that did not exist; a Cursor representative called it “an incorrect response from a front-line AI support bot” (CX Today).
AI-only service can lower quality. Klarna said in February 2024 that its AI assistant handled two-thirds of customer service chats in its first month. In May 2025, chief executive Sebastian Siemiatkowski said the AI-first approach had produced lower quality and that Klarna would make sure customers can always reach a person (Entrepreneur).
The common safeguards are the same for every tool on this page: restrict the AI agent to approved help content and policies, review a sample of its conversations every week, offer a clear route to a person, and test refunds and other actions in a sandbox before going live.
The rules on AI customer service
Several laws require a business to tell customers they are talking to an AI. This section is general information, not legal advice.
| Rule | Where | What it requires | In force |
|---|---|---|---|
| EU AI Act, Article 50(1) | European Union | People must be told they are interacting with an AI system, unless it is obvious, no later than the first interaction; the 2026 Digital Omnibus (Regulation (EU) 2026/1744) did not delay this duty | 2 August 2026 |
| Maine LD 1727 | Maine | Clear and conspicuous disclosure when a chatbot could mislead a reasonable consumer into thinking it is human | Signed 12 June 2025 |
| Utah AI Policy Act, as amended by SB 226 | Utah | Disclose AI when a consumer clearly asks; regulated occupations must disclose up front in high-risk interactions | Amendments effective 7 May 2025 |
| California SB 1001 (BOT Act) | California | No bot may knowingly mislead a person about its artificial identity to drive a sale | 1 July 2019 |
| FCC Declaratory Ruling 24-17 | United States | AI-generated voices are “artificial” voices under the TCPA, so AI robocalls need prior express consent | 8 February 2024 |
California’s companion chatbot law, SB 243, excludes chatbots used only for customer service (Perkins Coie). The US Consumer Financial Protection Bureau has warned banks that chatbots can trap customers in “doom loops” without a route to a person (CFPB, June 2023).
The simplest way to comply everywhere is for the AI agent to say it is an AI in its first message, and to hand over to a person on request.
Best AI for customer service by situation
Best AI customer service agent overall: Fin
Fin has the most user reviews of any dedicated AI agent, a published $0.99 price per outcome, and works on Zendesk, Salesforce, HubSpot or Intercom.
Best AI helpdesk: Zendesk

Freshdesk starts at $19 per agent a month billed annually with an AI agent included, and rates higher than Zendesk on both G2 and Capterra.
Best for small business: Tidio, or Freshdesk for a full helpdesk
Tidio has a free plan and an AI agent from $32.50 a month. A small team that also handles email tickets is better served by Freshdesk.
Best for HubSpot users: HubSpot Service Hub
HubSpot Service Hub keeps support conversations on the same record as sales and marketing, with an AI agent at about $0.50 per resolved conversation.
Best for Salesforce users: Agentforce, or Fin on Salesforce
Salesforce Agentforce is a Gartner Leader in both relevant Magic Quadrants. Salesforce also lists Fin as a ready-made service agent that connects to a Salesforce org (Salesforce).

Best free option: Tidio, HubSpot or Help Scout
Tidio offers 50 Lyro conversations free, and HubSpot Service Hub and Help Scout have free helpdesk plans, though their AI agents cost extra or need a paid plan.
How to choose AI for customer service
- Start from your helpdesk. If the team uses Zendesk, Salesforce or HubSpot, compare that vendor’s built-in AI against Fin on the same helpdesk before switching platforms.
- Count your volume in the vendor’s unit. Ask each vendor to price last month’s real conversations in its own unit: outcomes, resolutions, sessions or conversations.
- Ask how a resolution is measured. A customer who leaves without replying may be counted as resolved. Zendesk’s verified resolution tier and Fin’s uncharged handoffs are examples of the definitions to check.
- Test on your own tickets. Run the AI agent on a sample of past tickets, or in a trial, before it answers live customers. Fin and Zendesk offer 14-day trials, Tidio a 7-day trial.
- Keep a person in reach. 87% of customers say a company using generative AI must offer access to a human, according to Gartner, and the EU AI Act requires AI disclosure.
- Check the overage rules. Zendesk lets admins cap or pause the AI agent; Gorgias and Fin bill overage per unit. Set a monthly cap before launch.

Freshdesk is the best-value alternative, and Gorgias is the best AI helpdesk for ecommerce.

Can AI replace customer service agents?
AI does not replace a whole customer service team today. Gartner found in 2025 that only 20% of customer service leaders had reduced agent headcount because of AI, predicts that no Fortune 500 company will have fully eliminated human customer service by 2028 (Gartner), and reports that 87% of customers say a company using generative AI must offer access to a human. AI agents handle a share of routine questions, and human agents handle the rest.
What resolution rate can an AI customer service agent achieve?
No independent, audited data on AI customer service resolution rates exists. Vendors claim 70% to 80%: Fin reports a 76% average, Tidio 75% and HubSpot 70%, each with its own definition. Gartner found only 14% of customer issues fully resolved in self-service, and Gartner predicts agentic AI will resolve 80% of common issues by 2029.
Is a company responsible for what its AI chatbot tells customers?
Yes, a company is responsible for what its AI chatbot tells customers. In Moffatt v. Air Canada in February 2024, a Canadian tribunal held Air Canada liable for wrong fare information given by its website chatbot and rejected the argument that the chatbot was responsible for its own statements.
Do I have to tell customers they are talking to an AI?
In the European Union, yes: Article 50 of the EU AI Act has required businesses since 2 August 2026 to tell people they are interacting with an AI unless it is obvious. In the United States, Maine requires disclosure when a chatbot could mislead a reasonable consumer, Utah requires it when a consumer asks, and California prohibits bots that knowingly mislead people about being artificial to drive a sale.
What is the difference between an AI chatbot and an AI agent in customer service?
An AI chatbot in customer service answers questions from help content, while an AI agent can also take actions in other systems, such as issuing a refund, changing an address or cancelling an order, and decides when to hand over to a person. Fin, Sierra, Zendesk and Salesforce Agentforce sell AI agents; general assistants such as ChatGPT are compared on best AI chatbots.
Is Intercom Fin owned by Salesforce?
Yes. Salesforce completed its acquisition of Fin, the company formerly called Intercom, on 10 September 2026, after announcing the deal for about $3.6 billion on 15 June 2026. Salesforce says Fin continues to work with the helpdesks companies already use, and Intercom remains the name of Fin’s helpdesk product.
