Ask anything. Learn instantly.

Know.it is a real-time AI teacher. You ask any question and it generates a 2–5 minute lesson on the spot — synchronized voice narration plus animated visuals that draw and move to explain the idea, rather than a pre-recorded video.

Yes. You can watch one lesson with no sign-in, and get unlimited lessons after a free sign-in. Know.it is free to use during its beta.

Seven: English, Hindi, Marathi, Tamil, and Telugu, plus natural code-mixed Hinglish and Minglish.

Unlike pre-recorded videos, every lesson is generated live for your exact question. Unlike a text chatbot, it teaches with synchronized voice and animation that actually depicts the concept — the apple falls, the equation solves, the diagram draws itself.

No — your first lesson needs no account. Sign in (free) for unlimited lessons and to save them across your devices.

Most lessons run about 2 to 5 minutes, and playback starts within seconds because lessons stream beat by beat as they generate.

Anyone curious — students, self-learners, and people who understand ideas better by seeing and hearing them than by reading walls of text. It's built to work on any phone.

Yes. It's built for any phone, even on a slower connection, and streams the lesson so it starts before the whole thing has finished generating.

Yes — you can download a polished PDF study guide of any lesson, and signed-in lessons are saved to your account.

Lessons are generated by AI and written to be accurate and answer-first, but AI can make mistakes — see our AI transparency page for how lessons are made and how to flag an issue.

Beyond single questions, you can state a goal (like 'learn Python from scratch') and Know.it builds a step-by-step course of visual lessons to get you there.

An AI planner turns your question into a lesson storyboard, a scene engine renders the animated visuals, and a text-to-speech voice narrates — composed live and streamed to you beat by beat.
