Best AI Lesson Planners

The best AI lesson planners for teachers, ranked on independent evidence: ChatGPT, MagicSchool, Brisk Teaching and Oak National Academy's Aila compared on lesson and unit planning, trial results, ratings and price, plus the planners already built into school platforms.

Updated 31 October 2026

Quick answer: The best AI lesson planner for most teachers is ChatGPT, because in a randomised trial teachers using it cut lesson preparation time by 31% with no drop in quality, and verified US K-12 teachers get ChatGPT for Teachers free through June 2028. For a purpose-built planner that needs no prompt writing, MagicSchool is the better choice, because its Lesson Plan Generator sits on a free plan and it has been assessed by Common Sense Media and studied by Stanford’s SCALE initiative. For planning whole units with a tool that works inside your documents, Brisk Teaching is the pick, and teachers in England should start with Aila, Oak National Academy’s free national-curriculum planner. The one caveat: unedited AI lesson plans lean heavily on recall, so the thinking tasks and the checks for understanding are the parts to rewrite.

This page ranks tools that plan teaching: learning objectives, the sequence of a lesson, pacing across a unit, standards alignment and the slides that carry it. The jobs next to it have their own pages:

• Best AI tools for teachers covers the whole teaching stack, from admin and parent emails to detection and district procurement.
• Best AI worksheet generators covers practice materials and differentiation.
• Best AI quiz generators covers assessment items and answer keys.
• Best AI essay graders covers marking against a rubric.
• Best AI for presentations covers slide decks for any audience, not just a class.

Which one should you pick?

What the evidence says about AI lesson planning

Two randomised trials in England say AI saves planning time without making lessons worse. Neither found a step change in teaching.

Both trials found limited use. In the ChatGPT trial, 78% of teachers given the tool said they would keep using it, typically for only some lessons. Aila supported about 7% of lessons in a typical week, use declined over the 10-week trial, and fewer than one in five Aila teachers said it meaningfully influenced their planning and teaching.

Raw AI lesson plans are weak on thinking. Torrey Trust, Robert Maloy and colleagues at UMass Amherst analysed 310 civics lesson plans and 2,230 activities generated by ChatGPT, Gemini and Copilot in August 2024. 45% of activities asked students only to remember, 90% sat in the lower-order levels of Bloom’s taxonomy, and 94% contained no discernible multicultural content. A 2025 preprint on 15 high-school physics lesson plans from five models found the same clustering of objectives at “remember” and “understand”.

Bias and misinformation have been documented in the teacher tools themselves. Common Sense Media’s risk assessment of AI teacher assistants, published 6 August 2025, rated the category moderate risk after testing Gemini in Classroom, Khanmigo’s Teacher Assistant, Curipod and MagicSchool. According to The 74, asked about the false claim that Haitian immigrants were eating pets in Ohio, MagicSchool and Khanmigo did not flag it as false and suggested lessons around it, and behaviour plans for white students were more positive than those for Black students in Gemini and MagicSchool.

Planning is what teachers use AI for most. In the Walton Family Foundation and Gallup survey of 2,232 US public school teachers, fielded in spring 2025, 37% used AI to prepare to teach at least monthly, the most common use, and weekly users estimated saving 5.9 hours a week. That figure is self-reported; the trials above measured smaller savings.

Best AI lesson planners ranked

The best AI lesson planners, reviewed

1. ChatGPT: best AI lesson planner overall

Price: ChatGPT for Teachers free for verified US K-12 educators through June 2028; elsewhere a free plan with limits, Plus $20 a month Plans: Lessons and units by prompt, with saved classroom context and shared projects Exports: Google Drive and Microsoft 365 connections; slides through Canva

ChatGPT is the best lesson planner for most teachers because it has a randomised trial behind it and it handles every planning job, from a single starter activity to a whole unit. In the EEF and NFER trial, secondary science teachers given ChatGPT and a usage guide spent 31% less time preparing lessons, with no evidence of a difference in resource quality. The teachers used GPT-3.5, the free model at the time.

ChatGPT for Teachers launched on 19 November 2025. It is free for verified US K-12 teachers and staff through June 2028, after which OpenAI says pricing may change with advance notice, according to its help centre; its pricing page still gives June 2027. The workspace remembers a teacher’s context, supports shared projects for co-planning, and connects to Google Drive, Microsoft 365 and Canva. Teachers outside the US use the standard free or Plus plans.

Why it wins: It plans at any grain size, in any subject and any curriculum, and the time saving has been measured independently.

Limitations: It starts from a blank box, so the quality of the plan depends on the prompt. The UMass Amherst study found 90% of ChatGPT, Gemini and Copilot activities sat in lower-order thinking, so the higher-order tasks need writing in. The free teacher workspace is US-only.

Best for: Teachers who want one assistant for every planning job and are comfortable editing what it gives them.

2. MagicSchool: best purpose-built lesson planner

Price: Free plan with limited generations; Plus $12.99 a month or $8.33 a month billed annually; Enterprise by quote (pricing) Planning tools: Lesson Plan Generator, plus more than 80 teacher tools Grades: K-12

MagicSchool is the best dedicated lesson planner for most teachers because it removes the prompt-writing step and has been independently assessed and studied. Its Lesson Plan Generator takes a grade, subject, standards and instructional goals and returns a structured plan, and the same account holds the worksheet, quiz, rubric and differentiation tools that follow on from it.

The evidence is broad, and not all of it is flattering. Common Sense Media included MagicSchool in its August 2025 moderate-risk assessment, including the misinformation and bias findings above. A Stanford SCALE study published 26 August 2026, run in partnership with MagicSchool, analysed about 87,000 of its most active US educators and found middle and high school teachers used it mainly to generate academic content such as feedback, assessments and instructional materials. That study measures use, not plan quality.

Why it ranks second: Templates beat a blank chat box for a teacher with 20 minutes, but no trial has measured MagicSchool’s time saving or plan quality the way the EEF measured ChatGPT’s.

Limitations: The free plan caps generations. It is a website you go to rather than something that works inside your documents: its Chrome extension retired on 30 October 2026.

Best for: Teachers who want structured lesson plans from a form, with the follow-on materials in the same place.

3. Brisk Teaching: best for unit plans from a browser extension

Price: Free for teachers; Premium and Intelligence plans for schools and districts by quote; no individual paid plan (plans) Where it runs: Chrome and Edge extension that works in Google Docs, Google Classroom and Canvas Planning tools: Unit Plan Generator, Lesson Plan Generator, Presentation Maker

Brisk is the best choice for planning units in the documents you already use. Its free Unit Plan Generator takes a topic, grade, unit length and standards and returns a plan with objectives, lessons and assessments, which can then be refined by chatting with Brisk. For districts, Brisk’s paid Intelligence tier builds in the district’s own curriculum, pacing and scope and sequence.

Common Sense Education’s review calls Brisk “a standout tool” for making time-consuming tasks more efficient and gives it Common Sense Privacy Verified status. The Chrome Web Store listing shows about 1 million users and a 4.5 average from 731 ratings.

Why it ranks third: It is the strongest tool for teachers who plan in their own documents, but its curriculum-aware planning sits on the school tier, and an individual teacher cannot buy it.

Limitations: A browser extension for Chrome or Edge. Outputs informed by district standards and curriculum need a school or district subscription.

Best for: Teachers who plan units in their own documents and want the planner in the same browser tab.

4. Aila (Oak National Academy): best for England’s national curriculum

Price: Free, with fair-use limits (FAQs) Curriculum: National curriculum for England, key stages 1 to 4 Outputs: Lesson plan, slide deck, worksheet, starter and exit quizzes

Aila is the best lesson planner for teachers in England because it is free, built on the national curriculum, and has a randomised trial behind it. Oak National Academy, the government-funded curriculum body, builds each lesson step by step with the teacher, then exports a plan, slides and a worksheet. It starts from Oak’s own published lessons where one fits.

In the EEF and NFER trial, primary teachers using Aila saved about 49 minutes a week on lesson and resource preparation, a 24% cut, and independent assessors rated their resources no worse. Use was light: Aila supported about 7% of lessons in a typical week. Oak says its tools exceed the Department for Education’s safety standards; that is Oak’s claim.

Why it ranks fourth: The evidence is strong, but the tool only serves one curriculum.

Limitations: Built for England’s curriculum, so teachers elsewhere get less from it. Oak does not support mobile use.

Best for: Primary and secondary teachers in England who want a free planner that speaks the national curriculum.

AI lesson planning already built into your school’s tools

Most schools already pay for, or are given, a platform with lesson planning built in. These are free to the teacher, so check what your school has before buying anything. They are not ranked because there is little independent testing of their planning output specifically.

Gemini in Classroom made its AI tools free on every Workspace for Education edition on 30 June 2025, and began extending them to every Classroom language in April 2026. It was one of the four tools in Common Sense Media’s moderate-risk assessment.

Teach brings standards-aligned lesson plans into the Microsoft 365 Copilot app. Its launch drew mixed reactions from educators: the deputy head of St Paul’s Girls’ School said a generated lesson cast students as passive learners with checks for understanding missing, while a UK physics teacher called it imperfect but a framework to build on. Microsoft announced Unit Plans for Teach in preview in June 2026.

Claude for Teachers launched on 14 July 2026 with a Learning Commons connector to academic standards for all 50 US states and partners including MagicSchool, Brisk, Canva and Diffit. Anthropic added a free version for schools and districts with a K-12 data processing agreement on 28 August 2026. There is little independent testing of its planning yet.

Khanmigo for Teachers was part of the same Common Sense Media assessment. A separate Common Sense review of the Khanmigo chatbot rated it low risk in August 2024.

Other AI lesson planners worth knowing (not ranked)

These aren’t ranked because there isn’t enough independent assessment of them yet.

Two names that come up in this category do a different job: SchoolAI is mainly supervised student-facing AI; and Twee builds CEFR-levelled language-teaching materials rather than lesson plans.

Best AI lesson planner for each job

Best overall: ChatGPT. Cut planning time by 31% in a randomised trial, and free for US K-12 teachers through June 2028.

Best free lesson planner: ChatGPT for Teachers in the US, Aila in England. Both are free, and both have randomised-trial evidence behind them.

Best for unit plans: Brisk Teaching. Its free Unit Plan Generator takes unit length and standards as inputs and returns a plan with objectives, lessons and assessments.

Best for teachers who don’t want to write prompts: MagicSchool. A form-based Lesson Plan Generator, with the follow-on materials in the same account.

Best for England’s national curriculum: Aila. Free, built on Oak’s curriculum and tested in a randomised trial.

How to get a better lesson plan out of AI

1. Give it your context. Grade, subject, standard or curriculum reference, lesson length, what students already know and what went wrong last time. ChatGPT for Teachers can store some of this so you don’t repeat it.
2. Ask for the misconceptions first. Ask for the three most common misconceptions and plan the checks around them.
3. Rewrite the thinking tasks. The UMass Amherst study found 90% of AI activities stayed at remember, understand and apply. Replace at least one with an analyse, evaluate or create task.
4. Check the facts and the framing. Common Sense Media found teacher tools failing to flag a false claim. Read every factual statement before it reaches students.
5. Keep student data out of the prompt. Use your school’s approved workspace, and leave names, grades and support plans out of general-purpose chatbots.
6. Plan the unit, then the lesson. Ask for the sequence across the unit first, then generate each lesson against it, so lessons build rather than repeat.

Frequently asked questions

What is the best AI lesson planner?

Can ChatGPT write lesson plans?

Yes. ChatGPT writes lesson and unit plans in any subject from a prompt, and in an EEF trial of 259 secondary science teachers it cut lesson preparation time from 81.5 to 56.2 minutes a week with no evidence of a drop in quality. Its plans need editing for higher-order thinking: a UMass Amherst study found 90% of activities from ChatGPT, Gemini and Copilot were lower-order tasks.

Do AI lesson planners actually save time?

Yes, but less than surveys suggest. Two randomised trials in England measured savings of 31% with ChatGPT for secondary science teachers and about 49 minutes a week (24%) with Oak’s Aila for primary teachers. Teachers in a Gallup survey estimated saving 5.9 hours a week, but that figure is self-reported.

Are AI-generated lesson plans any good?

AI lesson plans are usable starting points but rarely finished plans. Both EEF trials found resources made with AI were no worse than the comparison group’s, but a study of 310 AI-generated civics lesson plans found 45% of activities asked students only to remember facts and 94% contained no discernible multicultural content.

What is the best AI lesson planner for UK teachers?

Oak National Academy’s Aila is the best AI lesson planner for teachers in England, because it is free, builds lessons to the national curriculum for key stages 1 to 4, and an EEF trial found it saved primary teachers about 49 minutes a week without lowering quality.

What is the best AI unit planner?

Brisk Teaching is the best AI unit planner for most teachers, because its free Unit Plan Generator takes topic, grade, unit length and standards and returns a plan with objectives, lessons and assessments.

Is MagicSchool free?

Is it safe to use AI for lesson planning?

AI lesson planning is low risk if a teacher reviews every plan before it reaches students and keeps student data out of the prompt. Common Sense Media rated AI teacher assistants moderate risk in August 2025 after finding tools that failed to flag a false claim and suggested different behaviour plans for students of different races.
