Multiple clips, dual captions, a real timeline — 100% on your phone
Assemble several clips into one video, auto-caption with a second translated line, and fine-tune every detail on Pro Editor's real timeline — trim, split, drag, restyle. Totally on-device, no server, nothing ever uploaded. Free, no watermark, no paywall, no subscription.
Live preview · Pop style · one word highlights at a time
Features
Import up to 10 clips at once, reorder them, trim each one's start and end, and Captioneer stitches them into one continuous video with captions that never straddle a cut.
Split clips, drag captions into place, pinch to resize, scrub the filmstrip — a genuine multi-track timeline, not a single preview screen. Full undo/redo throughout.
Add a second, translated caption line in one tap — a primary and a secondary track, styled independently. Reach a wider audience or make language-learning content, fully on-device.
Pop, Karaoke, Clean, Bold Box, Minimal, Neon Glow, Cute Pastel, and Impact Red — plus font, size, color, and background customization on top. Switch anytime before export.
Captions are composited directly into the video, frame by frame — not a subtitle track. They show up everywhere, on every app.
Every caption is timed to the word, not the sentence, so highlights land exactly where the speech does.
Every feature, every style, no watermark. No ads, no in-app purchases, no subscription.
Everything — import, transcription, editing, export — runs locally with no server, not ours, not Apple's. No account, no analytics, no ads — ever.
How It Works
Pick one clip or several from your photo library — reorder and trim each one on the Assemble & Trim screen before they join into a single timeline.
Captioneer transcribes the audio automatically, then generates captions in your chosen style — 8 to choose from. Add a dual translated line if you want one, then split, trim, and drag captions right on Pro Editor's timeline. The preview updates live as you edit.
Tap any word to correct it, then export. Captions are baked into the MP4 at full quality — save to Photos or share straight to TikTok, Reels, or Shorts.
