Turn lectures into answers & notes
Stop re-watching long recordings. Start from a supported lecture to create a transcript, summary, notes, and flashcards; timestamp-capable modes can add cited answers.
From recording to study material
Open a supported lecture in your browser and click Silestis — or upload a recording or paste a supported link. Silestis produces a transcript you can search and use to generate flashcards on Go and higher. Structured notes and chapter marks require Pro or Max. Generating study material uses credits; timestamps depend on the selected mode.
Find exactly what the professor said
Search the transcript for a term and, when timestamps are available, jump to the relevant moment. Ask questions in plain language — "what did she say about gradient descent?" — and use clickable [mm:ss] references when the selected mode provides them. Semantic search can help locate related passages across a library.
Built for the way students work
- Multilingual transcription and translation, with language support depending on the selected mode.
- Export notes as PDF or DOCX to share with classmates.
- Organize recordings by course in folders.

Answers & notes — FAQ
How do I turn a lecture recording into notes?
Open a supported lecture in your browser and click Silestis — or upload the recording or paste a supported link. Silestis creates a transcript. You can then generate flashcards on Go and higher, or structured notes and chapter marks on Pro and Max. Generating study material uses credits; timestamps depend on the selected mode.
Can I transcribe lectures from my university portal?
The Silestis extension supports many lecture players, but not every site or stream format. You only transcribe content you already have permission to access; Silestis does not bypass DRM, paywalls, or source permissions.
Can I make flashcards from a lecture?
Yes. On Go and higher, you can generate key-point flashcards from the transcript to review for exams without re-watching the whole lecture. Each generation uses credits; notes and chapters require Pro or Max.
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.
Start from the supported lecture page you already use.
Open the video and click Silestis to start a transcript, summary, and notes workflow on the page. Timestamp-capable modes can also return cited answers, including when no source transcript exists.
