From raw clip to captioned video in minutes
Every screen below is a real recording of the app on a phone. Each one plays when you scroll to it.
Import and trim, with your thumbs
Pick a video with the system picker and trim it on the timeline with drag handles. No account, no upload.
Automatic captions that never leave your phone
whisper.cpp runs on your device. One-time speech model download (about 82 MB), then captions work offline. Fix wording and timing segment by segment, with a live preview over the video.
Styles that match your channel. In two languages.
A set of free caption styles, plus additional Pro templates. Add a second subtitle language with on-device translation — the text never leaves the phone.
AI Cut: one tap, no dead air
One tap finds long silences and filler words. Review the proposed cuts and apply the ones you want.
Export straight to your gallery
1080p MP4 saved directly to your gallery. With Pro, choose resolution and frame rate, change playback speed and add background music.
A full-screen teleprompter, free
Paste your script, set the speed and read it while you record. Lines you have read fade out, so your eyes always land on the next one.
Voiceover over your own footage
Record a take over the preview and mix it into the exported video. The original audio ducks while you talk.
Pro, your way: once or monthly
Capline Pro as a one-time lifetime purchase or a monthly/yearly subscription, sold through Google Play. Clear prices, easy to close, restore any time.
Free does the job. Pro goes further.
