Captions Bro: Auto Subtitles

Automatic subtitles in a tap, karaoke word highlighting, a full multi-track timeline and a built-in teleprompter. Everything you need to publish vertical video.

Captions Bro turns raw phone footage into finished vertical video — automatic subtitles, karaoke-style word highlighting, a real editing timeline, and a built-in teleprompter, all in one app.

Record with the teleprompter, pull clips in from Photos, let the app transcribe the speech on device, then style the captions until they stop the scroll. What you see in the preview is exactly what gets exported.

AUTOMATIC SUBTITLES AND CAPTIONS • Generate subtitles from speech automatically — transcription runs on device • Karaoke-style highlighting that lights up each word as it is spoken • Bold, social-ready caption templates with fonts, colors, outlines and shadows • Add punctuation, remove filler words, and regenerate any line • Split, merge, retime, restyle and correct captions by hand • Mixed-language speech supported with a secondary language

A REAL EDITING TIMELINE • Multi-track timeline — trim, split, reorder, duplicate and delete clips • Speed, reverse, freeze frames and transitions between clips • Keyframe animation for position, scale, rotation and opacity • Text, image and video overlays, with masks and background removal • Color grades, filters and effects • Noise reduction, voiceovers and sound effects • 9:16, 4:5 and square reframing for every platform

TELEPROMPTER Write or import a script, set the scroll speed, and record yourself reading it while the camera rolls. Built for talking-head videos, explainers, tutorials, UGC, course clips and sales videos — the formats where the words matter more than the b-roll.

EXPORT AND SHARE • Export MP4 or MOV with the captions burned in • Choose resolution and frame rate to match where you are posting • Save to Photos, or share to Instagram, TikTok, YouTube, Facebook and Messages

WHY CREATORS USE IT Most people watch with the sound off. Captions are what keep them watching — and typing them out by hand is the slowest part of publishing anything. Captions Bro handles the transcription, the timing and the styling, and leaves the editing to you.

Everything runs on your iPhone, so a weak signal never stops you working.
