CaptionLab helps creators turn raw video into clear, polished captions without typing every word by hand.
Upload a clip, choose your caption language, and let AI create timed subtitles you can review, edit, style, and export. It is built for short-form creators, educators, coaches, podcasters, agencies, and anyone who needs videos to be understandable with the sound on or off.

Subscribing is now reliable. Plans are fetched from Google Play with retries, so a slow connection on first launch no longer leaves Subscribe failing with a "temporarily unavailable" message.
Also in this update:
- Caption words now fade in as they animate, instead of snapping to full opacity and then growing into place.
- Fixed the Scanline style, whose sweeping highlight was invisible.
- New caption lockups, including text placed behind the speaker.
