Upload audio or video — Noctanotes listens, understands, and writes the study notes so you don't have to.
Noctanotes doesn't just transcribe — it structures what you hear into notes worth studying from.
Powered by Whisper, with automatic chunking so even long lectures transcribe reliably.
Claude organizes the transcript into headings and key terms — not a wall of text.
Download a print-ready PDF or the raw HTML, ready wherever you study.
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. Every lecture you process is saved to your dashboard.
