Khanly AI lecture note taker
Record your lecture. Get notes you'd actually study from.
Ace - Lecture Notes records your lecture right in the browser, or takes an audio file you already have, and turns it into clear study notes organized by concept — not a transcript with headings.
How it works
- Press record in your browser — with a live timer, waveform, and pause/resume — or upload an MP3, WAV or M4A file.
- Optionally attach your professor's slides as a PDF so the notes use the same terms.
- Long lectures are split into parts and transcribed while you record.
- Ace writes your notes, and everything saves automatically.
What you get
- Professor's exam hints: moments like "this will be on the exam" or "remember this" are pulled out and highlighted.
- A summary and key takeaways.
- Detailed notes grouped by concept, with the professor's examples.
- Cornell notes and key vocabulary.
- Exam questions and flip-through flashcards.
- A Study Assistant that answers questions using only what your lecture covered.
Why use an AI lecture note taker?
Typing notes while a professor talks means you miss half of what's said. An AI lecture note taker lets you listen, then gives you notes organized by concept, with the parts your professor stressed pulled out for you.
