Turn lectures into searchable notes
Stop re-watching three-hour recordings. Transcribe once, then search, ask questions, and study from flashcards.
From recording to study material
Upload a lecture recording or paste a link to the video. Silestis produces a timestamped transcript, then turns it into the things you actually study from: structured notes, chapter marks so you can navigate by topic, and flashcards for the key points. Save 4+ hours a week you'd otherwise spend scrubbing and re-typing.
Find exactly what the professor said
Search the transcript for any term and jump to the moment it was mentioned. Ask questions in plain language — "what did she say about gradient descent?" — and get an answer with clickable [mm:ss] timestamps. Across a whole semester of recordings, semantic search finds the right moment in seconds.
Built for the way students work
- 100+ languages with translation — follow a lecture in another language.

searchable notes — FAQ
How do I turn a lecture recording into notes?
Upload the recording or paste a link to the lecture video. Silestis transcribes it with timestamps, then auto-generates structured notes, chapter marks, and flashcards you can study from.
Can I transcribe lectures from my university portal?
If you can play the video in your browser, the Silestis extension can detect and transcribe it. You only ever transcribe content you already have access to.
Can I make flashcards from a lecture?
Yes. Silestis generates key-point flashcards from the transcript automatically, so you can review for exams without re-watching the whole lecture.
Does it handle long lectures?
Yes. Long-form transcription handles multi-hour recordings, and paid plans support videos up to 2–10 hours depending on the plan.
Every video you watch could be searchable.
Install the extension, hit transcribe, and never lose what was said in a lecture, meeting, or podcast again.
