Silestis vs Fathom
A meeting recorder and an audio/video knowledge tool — built for different jobs.
Fathom joins your Zoom, Meet, or Teams calls and produces recordings, transcripts, and summaries automatically. It's a clean fit for teams that live in meetings.
Silestis is built for any audio and video — paste a YouTube or podcast link, or grab a video with the browser extension, then search it and ask questions with timestamped answers. For lectures, webinars, and web video — content that never happens on a calendar — Silestis is the better tool.

Fathom — FAQ
Is Silestis a Fathom alternative?
If you want to transcribe and search any web video, lecture, webinar, or podcast — not just live meetings — yes. Silestis isn't a meeting bot; you paste a link or use the browser extension. Fathom is the better fit if your only need is auto-recording live calls.
Can I make study material from recordings?
Yes. Silestis generates notes, chapter marks, and flashcards from any transcript — great for lectures and webinars, which meeting tools don't focus on.
Where is my data processed?
In the EU on Cloudflare. Source files are deleted after transcription and are never used to train AI models.
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.
