Caption your next TikTok. That's it.
Free to start, no card, nothing uploaded. Drop in a clip and watch the captions write themselves.
Drop in your clip and Just Captions transcribes it and lays down clean, readable subtitles — on your iPhone, in about a minute. Free, private, and placed so TikTok's buttons never cover a word.
The short version: open Just Captions, drop in your clip, and it transcribes the speech and times subtitles to every word automatically. Pick one of four readable presets, then export an MP4 with the captions burned in and upload it to TikTok. No timeline, no manual typing, nothing uploaded to a server. Most clips are done in about a minute.
TikTok stacks its own UI over the edges of every video. Keep text inside the safe band and it stays readable in-feed, on the For You page, and anywhere the clip gets re-shared.
| What to set | Recommended for TikTok |
|---|---|
| Aspect ratio | 9:16 vertical (1080 × 1920) |
| Safe zone — bottom | Keep captions above the bottom ~15% (caption text, username, sound title) |
| Safe zone — right | Stay clear of the right ~12% (like, comment, share, profile icons) |
| Caption position | Centred, roughly the middle-to-lower third of the frame |
| Lines on screen | 1–2 short lines at a time — easiest to read at a glance |
| Style | High-contrast fill or outline so text survives busy backgrounds |
Just Captions applies these defaults for you — presets are pre-placed inside the safe zone and sized for one-glance reading, so you don't have to measure anything.
