Best AI lesson plan generators

Which AI lesson plan generators are free, and what do they cost?

Five of the seven are free for a single teacher for as long as they use them. Eduaide is free up to about 8 resources a month, and LessonSmith is free once, as a demo.

Khanmigo, Planbook and Common Planner are not in the table. Their pages did not show plan details when we read them on 11 November 2026, and we would sooner leave a row out than guess it.

Which one should you pick?

Pick by what your week looks like, not by the longest feature list.

You want one free account that does many jobs: MagicSchool

MagicSchool's free plan lists 80+ teacher tools, a chatbot, quizzes and writing feedback. Lesson plans are one tool among them. The free plan does not include unlimited generations or output history; those come with Plus at $12.99 a month. If you want quizzes and writing feedback from the same login as your lesson plans, start here. The roundups we read on 11 November put it first, and on breadth they are right.

You plan inside Google Docs: Brisk

Brisk is a Chrome and Edge extension. In its own words it works "in Docs, Slides, YouTube and your LMS", so the plan is written into the document you already have open. It is free for teachers, with 20+ tools and materials in 50+ languages. An extension lives in a desktop browser, so it is not the one for planning on a phone.

You want the cheapest paid plan: Eduaide

Eduaide Pro is $49.99 a year, which works out at $4.17 a month. Its free plan gives 24 credits a month, about 8 resources, across lesson plans, worksheets, organizers and classroom games. Eight is enough to find out whether you like what it writes.

You want learners to use the AI too: Flint

Flint is free for teachers and their students with no student limit, for up to 3 teachers in a workspace, and it includes chats, activities and class analytics. A whole school pays from $3,000 a year for up to 150 users.

You want reading material more than a plan: Diffit

Diffit's free plan makes classroom content on a topic, which you can edit, print and download as a PDF. It keeps what you made for 90 days. It is a resource maker first, so pair it with whatever writes your plan.

You want the plan to look good on a slide: Canva

Canva's Magic Write drafts the text inside a Canva design, and teachers get it free through Canva for Education. Choose it when the plan is going on a screen or a wall.

You teach outside the US and plan to term dates: LessonSmith

LessonSmith does three jobs: lesson plans, schemes of work and support plans for individual learners. You pick one of 11 curricula once, including CBC/CBE in Kenya, NERDC in Nigeria, CAPS in South Africa, NaCCA in Ghana and Cambridge International, and it uses that system's words, such as strand, sub-strand and TSC number. Each plan is saved onto its date in your term calendar and exports to Word or PDF. The AI lesson plan generator page shows two unedited plans.

Where is LessonSmith the weaker choice?

In three places, and you should know them before you try it.

• It is not free to keep. After the demo's 10 lesson plans you pay $2.50 a week or $8 a month. MagicSchool, Brisk, Flint and Canva do not charge a single teacher at all.
• It does fewer things. There is no quiz maker, no rubric tool and no slide deck. MagicSchool lists 80+ tools.
• It is new and small. LessonSmith launched in July 2026 and has far fewer teachers using it than any other tool on this page.

The longer comparison with MagicSchool, Eduaide, Brisk and Kuraplan covers curricula, languages and privacy.

Do you need a lesson plan generator, or is ChatGPT enough?

For a plan now and then, a chat assistant is enough, and these ChatGPT prompts for lesson plans will get you a usable one. A generator earns its place when you plan every day, because it remembers your curriculum, class and layout and you stop pasting them in.

What should you check before you rely on any of them?

• Whether it knows your curriculum by name or only when you paste it in. Ask for a plan on a topic you know well and read the outcomes.
• Every fact and every sum. All of these tools can be confidently wrong, LessonSmith included.
• What the free plan stops you doing. The limit is usually on saving and history, and you only meet it in week three.
• Where learner information goes. Do not type a child's name or medical details into any of them.
