Finals are coming.
Time to pull those grades up.
When the textbook is in a second language, a single chapter can eat the whole evening — and the grade still slips.
Mentis is an AI tutor in Telegram that breaks any chapter into a clear summary and walks your kid through it, step by step.
I built it to save my daughter's geography grade. It can do the same for yours.

Parents ask
A quick rundown of how Mentis helps kids and their parents
How does Mentis help families living abroad?+
Kids struggle with tough topics because the textbook is packed with terms in a new language. If a child thinks in their native language, they first need to understand it there — and only then go back to the original text. Mentis is that bridge: upload a textbook page and get an explanation in the native language in a minute.
We don't live abroad. Will Mentis still help?+
Yes. Mentis works for anyone dealing with text: school kids — for summaries and test prep, university students — for lectures, adults — for courses and books. Content generation works in 50+ languages, and the interface is in English and Russian.
What else can I use Mentis for?+
Not just school. University students — lecture notes and podcasts. Exam prep (SAT, IELTS, A-Levels) — quizzes on any topic. Adults — summaries of courses and books. Reading in a foreign language — a retelling in your native tongue. There's also Q&A on uploaded materials and audio podcasts.
What languages does Mentis support?+
Interface — English and Russian. Generation of summaries, quizzes and podcasts — 50+ languages. You can upload a textbook in German and get an explanation in English. Interface language and output language are picked independently.
How much does Mentis cost?+
Try it free: 1 material and 3 sources. Then 1000 Telegram Stars (≈ $20) for 6 months of unlimited use — all features, no limits. Payment happens inside Telegram.
