About
Ask the video. Get to what matters.
Silestis brings video and audio into a searchable library you can ask questions about. Start directly from Safari: open a supported video or audio page, briefly start playback, then use the Silestis Safari extension to import available subtitles or transcribe the audio. You can ask questions in the extension or continue in the app.
FROM SAFARI TO ANSWERS
Capture supported web video and audio without copying links between apps. Find the main ideas, explore explanations and ask follow-up questions.
YOUR LIBRARY, YOUR WORKFLOW
Search saved transcripts, read at your own pace and ask about one item or across your library. You can also import supported links and files, or record audio in the app.
PLANS AND ACCESS
Create a Silestis account to use cloud features. A free plan is available with limits. Optional Go, Pro and Max subscriptions can be purchased in the iOS app. If you already have an active Silestis subscription purchased on the web, sign in with the same account to use it here. Manage Apple subscriptions in your Apple account and web subscriptions on the Silestis website.
The Safari extension supports many websites, but not every source. Detection and processing depend on the website, available content and its length. AI answers may contain mistakes.
