All subjects · 20 languages · voice-narrated
Every doubt, explained like a great teacher would.
Stuck at 10 pm with nobody to ask? Don't want to raise your hand in a class of sixty? Ask here. A tutor explains it on a whiteboard, in your language — and you watch it, you don't copy it.
5 free questions. No card needed.
A real answer, real voice — “Why does sin(x) make a wave?”
Built for the doubt that never gets asked.
Asking in a full class is embarrassing, and the teacher isn't there when the doubt actually happens — especially the night before an exam.
A tutor at 10 pm that explains on a board, in your language. No hand-raising, no waiting for tomorrow.
ChatGPT gives an answer that gets copied straight into homework. Nothing is learned.
Explanations here are watched, not copied — there's no paragraph to paste. It's a tutor, not a cheat sheet.
Students don't ask, so you never know where the batch is stuck. When they do ask, there isn't time to answer all of them.
Doubts get answered at night without you. You get a morning view of what the whole batch is stuck on — and teach that.
Not a wall of text. A lesson.
Ask anything
Type your doubt in any subject, any language — from fractions to Fourier transforms.
Watch it drawn
A tutor writes, sketches and plots the explanation step by step. Every graph is computed, never guessed.
Hear it explained
Warm voice narration in your language, perfectly synced to the chalk. References to keep learning at the end.
Correct by construction: the AI never draws a graph freehand. It emits instructions like “plot y = sin(x)”, and our renderer computes the actual curve — so what you see is mathematically true.
