What Is Castmagic?
Castmagic is an AI-powered content repurposing tool for podcasters and content creators. It transcribes recordings, generates show notes, social media posts, and clips from uploaded audio or video files. It is primarily a post-production tool, not a live streaming tool.
Why Streamers Look for Castmagic Alternatives
Castmagic is designed for post-production content workflows — it doesn't provide live captions during a stream. Streamers looking for real-time captions and translation while they're live need a different tool. Castmagic also requires uploading recordings after the fact, which doesn't help with live accessibility.

Switching to StreamTranslate
Castmagic and StreamTranslate serve different purposes. If you want live captions during your stream, StreamTranslate is what you need. If you want to repurpose stream recordings afterward, Castmagic is useful for that. Many streamers use both.
Setup takes under 2 minutes: go to streamtranslate.live/control, select your speaking and target languages, copy the overlay URL, and add it as a Browser Source in OBS at 1920x1080. No account deletion or data migration needed.
