The workflow
What Boltis does differently from StreamGen
Boltis is built around the moment it happens. With one-key clipping, Twitch saves the last 60 seconds server-side, so Boltis does not record your screen while you play.
The clip then opens in the built-in editor. Choose a vertical layout, add automatic captions, and export a 1080 by 1920 video for TikTok, Shorts or Reels. There is no watermark or export limit on the core workflow.
Need a clip from an already-finished stream? Boltis is not the right tool for that job. It needs your own Twitch stream to be live, so a tool that works from a VOD or an uploaded file is the better fit in that specific case.

Does Boltis add a watermark?
Not unless you ask it to. Boltis adds nothing to an export by default. There is an optional "Clipped with Boltis.app" credit in the editor, switched off unless you turn it on.
Can Boltis make clips from a stream that has already ended?
