Upload a recording — Noctanotes transcribes it with Whisper and uses Claude to write clean, organized notes, ready to study from in minutes.
MP3, MP4, M4A, WAV, WEBM, and OGG, up to 500 MB per file.
Long recordings are automatically split into chunks during transcription, so multi-hour lectures work fine.
Noctanotes can auto-detect the spoken language, or you can specify one — including English, Afrikaans, French, German, Spanish, Zulu, and Xhosa.
Yes — switch to the "Record" tab to capture audio from your microphone right in the browser, then generate notes from it the same way.
A structured PDF (and the underlying HTML) with headings, key terms, and takeaways drawn from your recording — not just a raw transcript.
