How lecture transcription works
Upload the lecture
Drop in your recording – phone audio, a recorded class, or a lecture video, any format.
Get the transcript
AI transcribes the whole lecture into clean, timestamped text in minutes.
Study from the notes
Read the AI summary of the key points, ask chat to explain a concept, then export to TXT, Markdown, DOCX, or PDF.
Listening to a lecture twice is rarely the best use of an evening. Pepys turns the recording into a clean, timestamped transcript in minutes, then distills it into a study summary – the main concepts, the definitions, and the points the lecturer kept coming back to – so you revise from notes you can read and search, not an hour of audio.
When something doesn't click, the source is right there: every line is timestamped, so you can jump to the exact moment the lecturer explained it, and built-in chat can re-explain a concept or quiz you on it. Works across 99+ languages for any class, we never train on your audio, and you pay only for the minutes you transcribe – credits never expire.
Clean paragraphs. No more um's and ah's.
The left is what Pepys hands back – logical paragraphs with the filler stripped out, punctuated and readable. The right is the raw, one-line-per-segment dump most transcribers leave you with.
um so yeah everyone keeps telling you to like lead with your best line right but uh honestly if you give away the whole answer in the first second you know there's basically no reason for anyone to keep watching so the hook isn't kind of the smartest thing you say it's like a loop you open that they need to close and um that's the part that actually keeps people around

Lecture transcription – questions, answered
How do I turn a lecture into study notes?
Upload the lecture recording on this page – Pepys transcribes it into timestamped text and writes an AI summary of the key points in minutes. Your first 60 minutes are free, no card required.
Can I jump to where a concept was explained?
Yes – every line is timestamped, so when you hit something in the notes you don't follow, you can click straight back to that moment in the recording.
How long can a lecture be?
There's no length limit – a 50-minute class or a three-hour seminar both work. Long recordings are chunked and stitched automatically with correct timestamps.
Does it work for lectures in another language?
Yes. Language is auto-detected across 99+ languages, and you can translate the finished transcript so a foreign-language class still reads as study notes.
Is my recording kept private?
Yes. We never train AI on your audio, transcripts, or summaries, and you can auto-delete the recording after it's transcribed.
