A tutor that draws.
Chalk turns any question into a narrated, animated lecture on an AI blackboard — then lets you pause at any moment and ask a follow-up it answers from that exact point. Built on video-as-code, so the graphs, geometry and equations are correct, not guessed. It covers the Primary, O-level and A-level syllabus, university STEM, and anything you're curious about — in your language.
Ask anything, get a lecture.
Type a concept — from the Primary/O-level/A-level syllabus to university STEM to anything you're curious about — and Chalk generates a narrated, animated video that actually explains it.
Drawn correctly, not guessed.
Lectures are generated as code and rendered deterministically, so the graph, the geometry and the equations are exact — never a video model's hallucinated numbers.
Pause and ask at any moment.
Stop the video anywhere and ask a follow-up; the tutor answers from that exact moment and can draw the answer on the same blackboard.
