About LessonSmith
What is LessonSmith?
LessonSmith is an AI lesson plan generator and scheme of work generator for teachers. A teacher sets their curriculum, class level and term dates once, and it drafts lesson plans, term-long schemes of work and support plans for individual learners. Everything saves to the teacher's library and exports to Word or PDF, and lesson plans can also be edited in place.
The AI lesson plan generator and scheme of work generator pages show what each one produces.
Who makes LessonSmith?
Ryan Mwangi founded LessonSmith and builds it in Nairobi, Kenya. The product is operated and sold by VoussoirAI, which is also based in Nairobi.
Ryan is on X as @ryanmwangiai and on Instagram as @airz.ryan.
Why did Ryan build LessonSmith?
Teachers write lesson plans and schemes of work by hand, often on a Sunday, in the same format for the same subject year after year. Ryan built LessonSmith so that paperwork arrives as a draft in minutes, and the teacher's evening goes on checking it and on the class. It began as a tool for Kenya's CBC, where a scheme of work has to line up with the term's real dates, half-term break and exam weeks, and it now drafts for 11 curricula.
What does LessonSmith stand for?
AI should not write a lesson. It does not know the class, the room or the kid in row three. What it can do is write the draft a teacher was going to write anyway, so every plan here is a draft, and the teacher reads and corrects it before it reaches a classroom.
There is no unlimited plan, and there will not be one. Each tier has a fixed number of plans, because an account with no ceiling is how a bot runs up an AI bill.
The shilling prices are real prices set in shillings, not conversions. Pro is KES 300 a week whatever the dollar does.
Learners' names and admission numbers do not belong in a lesson plan or scheme of work prompt, and the app says so where you type. The support plan tool, which is about one learner, works with initials or no name at all.
When did LessonSmith launch?
LessonSmith went live at lessonsmith.ai in July 2026. Paid plans are billed through Polar, the merchant of record, in US dollars or Kenyan shillings.
Schools could pay for their teachers from 4 September 2026, on what is now the Custom plan. On 19 September the free monthly plan made way for a one-off demo that needs no account. Weekly billing came on 2 November, at KES 300 a week for Pro. Since 7 November the library opens with no internet connection, so a saved plan can still be read and saved as a PDF offline. By November 2026, more than 50 accounts had been opened, counting one-off demos.
Which AI models does LessonSmith use?
OpenAI's GPT-4o-mini drafts every plan, and Google's Gemini Flash Lite takes over when GPT-4o-mini is unavailable. The API keys are held on LessonSmith's servers and never sent to the browser. Output can be wrong, so teachers are expected to read and correct every plan before they teach it.
Which curricula and languages does it cover?
It drafts for 11 curricula: CBC/CBE (Kenya), NERDC (Nigeria), CAPS (South Africa), the standards-based curriculum (Ghana), the National Curriculum (England), Common Core and NGSS (United States), CBSE and NCERT (India), the Australian Curriculum, FGOS/FOP (Russia), the International Baccalaureate, and Cambridge International. The app runs in 9 languages (English, Kiswahili, French, Spanish, Portuguese, German, Italian, Dutch and Russian), and plans are written in the language the app is set to.
LessonSmith is independent. It is not affiliated with, endorsed by or certified by any ministry, examination board or curriculum authority. Each curriculum has its own page under curricula.
Is LessonSmith connected to lessonsmith.org or lessonsmith.com?
No. This LessonSmith lives at lessonsmith.ai and has no connection to lessonsmith.org (a separate learning platform), lessonsmith.com (a domain listed for sale), the Lessonsmith course builder at lessonsmith-khaki.vercel.app, or the mesmundo/lessonsmith repository on GitHub.
