- 3Ready for vertical feeds. 9:16 shorts of up to 60 seconds each, with burned-in captions.
- 4Download and post anywhere: YouTube Shorts, TikTok, Instagram Reels.
- 5Part of the Pro plan, with 200 credits every month.
How it works
Stream as usual
Go live from the app or from OBS. Castream records every stream automatically, so there is nothing extra to turn on.
Press Generate
Open the stream in Streams on the web and press Generate. We transcribe the recording, line it up with your chat and pick the best moments.
Get your shorts
In a few minutes your shorts are ready, each with captions. We notify you when they are done.
Download and post
Watch each short, download the ones you like and post them to the platforms where your audience scrolls.
Why your chat makes better shorts
What most clip tools see
- Only the video and the words in it.
- Loud or fast moments, whether or not anyone cared.
What Castream sees
- Your words, lined up with your chat on the same timeline.
- The moments when viewers reacted, laughed or asked for more.
- Chat from every platform you streamed to, in one place.
Credits, explained simply
- 1 credit = 1 minute of recording. A 45-minute stream uses 45 credits, however many shorts come out of it.
- Pro includes 200 credits every month. The 3-day free Pro trial includes 30.
- Making shorts again from the same stream is free while we still have its transcript.
- Failed runs cost nothing. If a run fails before your recording is transcribed, the credits go back to your balance.
