Now in beta: free for now
AI clip finder + shorts editor
Find the clip.
Cut the short.
The editor is free.
OpenStreamTools finds the best moments in your Twitch VODs. Then you cut them into vertical shorts in a real editor: captions, freeze frames, several clips on one timeline.
During the beta everything is free, the AI and the clip finder included, with fair daily limits. Paid plans come later, and you'll hear first.
Footage: herloaf on Twitch, clipped with OpenStreamTools.
Free to edit. Pay for what runs on top.
AI clip finder
Give it a Twitch or Kick VOD and it finds the moments worth clipping. No more scrubbing through hours of stream. Clips come in the quality you streamed, up to 1440p.
Live mode
Press a key while you stream and the minute before becomes a clip, cut from your own OBS recording at full quality.
Vertical shorts editor
Cut, reframe and export vertical shorts in your browser. Your footage never leaves your computer.
Captions that stay put
The words belong to the video, not a separate track. Move, trim or split a clip and its captions follow. Nothing to re-sync.
Multi-clip timeline
Put several videos on one timeline, cut between them, and freeze any frame.
Remove profanity
Finds the swearing and hides it: masked on screen, with silence or a bleep underneath. One click.
Invite your editors
Bring up to 3 editors into your team's projects. No charge per seat, it's part of Pro.

Why we built it
Made with streamers, for streamers.
We built this next to streamers who clip their own streams. They asked for things, broke things, and told us when something felt off. That's why the crop tool remembers your facecam, and why captions belong to the video instead of the clip. Real editing sessions, not a roadmap meeting.
It's also why the editor is free. Editing runs on your computer, so it costs us nothing. Other tools sell you credits that run out mid-edit, uploads that sit in a queue, and a watermark unless you pay more. We only charge for the AI, the part that actually costs money to run.
