The AI copilot every Indian teacher deserves, but never had.
Indian teachers spend 3+ hours a day on lesson prep. Mentzi collapses that to under 10 minutes, generating curriculum-aligned, language-specific content that actually fits the classroom.

Impact · K–12 Schools · Maharashtra
Mentzi is being used by teachers across Maharashtra handling large class sizes, often 40–60 students per section, with no teaching assistants and minimal institutional support. The consistent feedback: lesson preparation that used to take 2–3 hours now takes under 10 minutes, without any loss of quality. Teachers are generating vernacular-first content aligned to the Maharashtra State Board curriculum and sharing quizzes directly with students via WhatsApp. The shift is measurable in how teachers describe their relationship to the job, less administrative, more human.
THE FULL STORY
An Indian schoolteacher's day ends long after the last bell. Three hours of it, every day, goes to lesson prep: writing plans, setting questions, adapting English-medium material into the language the class actually thinks in. Multiply by 9.4 million teachers and you get one of the largest unpaid content-production workforces on earth.
We sat in staff rooms before we wrote a line of code. What we heard: teachers don't want another portal, they want their evenings back. The output has to match the board, the grade, and above all the language. A Marathi-medium class doesn't need a translation of an English lesson; it needs a lesson conceived in Marathi.
The wedge was prep time, not "AI in education." One number to move: minutes per lesson plan. Everything else, quizzes, progress tracking, parent updates, earned its place only after the core promise held.
The interface assumes a tired user on a modest phone. One input, "photosynthesis, Class 7", and a structured, editable plan comes back in under a minute. Devanagari-first typography where the user is; nothing that needs a manual.
Original generation in ten-plus Indian languages, not machine translation. Curriculum mapping keeps every output aligned to CBSE, ICSE, and state board syllabi. Parent updates ride WhatsApp, so the parent side needs no app at all.
Lesson prep collapsed from 2–3 hours to under 10 minutes for teachers handling 40–60 students per section. 87% of active teachers report less daily stress, and, in their words, a job that feels less administrative and more human.
Vernacular isn't a feature, it's the product. Distribution in education is trust, transferred staff room to staff room. And a teacher will forgive a missing feature long before a wrong answer, accuracy budgets beat feature budgets.
INSIGHTS
Every major EdTech platform in India has been built for students. The teacher, the actual delivery vehicle for learning, has been ignored. Mentzi exists because fixing the teacher experience fixes learning outcomes.
Most multilingual AI products translate from English. Mentzi generates directly in the target language, because a translated explanation of a concept is structurally different from one written natively.
India has 9.4 million school teachers. If each spends 3 hours daily on prep, that is 28 million person-hours a day spent on content generation, content AI can produce in seconds.
