• AI lecture notes

Record the lecture. Get notes you can actually revise from

Hit record at the start of the lecture and put your phone down. Thaxas transcribes the recording, pulls out the structure — the concepts, the definitions, the moment the lecturer said "this will be on the exam" — and keeps a timestamp on everything, so a note in your revision guide links back to the exact minute it was said.

Writing during a lecture makes you a stenographer

There is a well-known trade-off in a live lecture: the more completely you transcribe, the less you understand, because transcription and comprehension compete for the same attention. Students who type verbatim capture more words and remember less of the meaning. But stopping writing to listen properly means that in six weeks, when revision starts, the lecture is simply gone.

Recording resolves the trade-off rather than splitting the difference. Listen, argue with the lecturer in your head, ask a question — and let the recording be the transcript. Our take on the note-taking research is in how to take lecture notes.

From audio to revision, in one pass

  1. 1

    Record in the browser, or upload after

    Record straight into a space, or bring in an existing MP3, M4A or WAV — a recording made on your phone, or the one the department published.

  2. 2

    Get a transcript with timestamped notes

    The transcript is structured into notes rather than dumped as a wall of text: concepts, definitions and the asides that turn out to matter, each anchored to its moment in the audio.

  3. 3

    Ask it questions

    The recording joins the space, so grounded chat can answer across the lecture and the reading together, and cite a timestamp as readily as a page.

  4. 4

    Turn it into practice

    Generate flashcards or a quiz straight from the lecture — while it is still fresh enough that you can tell whether the questions are fair.

Common questions

What audio formats can I upload?

MP3, M4A, WAV and the other common formats, up to 50MB per file. You can also record directly in the browser without uploading anything.

Does it identify different speakers?

The transcript captures the lecture as spoken and structures it into notes. It is built for a single-lecturer recording rather than for producing formal minutes of a multi-speaker meeting.

How accurate is the transcription?

Good on clear audio; degraded by a bad room, a distant microphone or heavy background noise, as any transcription is. Because notes carry timestamps, you can always jump back to the audio and check what was actually said.

Can I search across all my recorded lectures?

Yes. Recordings in a space are searchable alongside its documents, so a question can be answered from the lecture, the slides and the reading at once.

Try it on your own material

Upload your notes, slides or lecture recordings and get a tutor that answers only from them — and says so when they don't cover it.
