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 supported audio and video sources — paste a YouTube or podcast link, or grab a video with the browser extension, then search it and ask questions with timestamped answers where available. 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 supported web videos, 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?
Account data, transcripts, and retained playback media use EU-configured storage. AI processing may use vetted providers outside the EU under appropriate safeguards. Source media is deleted after transcription by default.
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.
