Subtext: Auto Captions

Word-perfect animated captions, burned in on your iPhone in seconds. Free with unlimited exports — one price removes the watermark, forever. No subscription.

Captions sell the video. Subtext gives you word-perfect, animated captions burned into your short-form clips — transcribed entirely on your iPhone, in seconds.

No upload. No queue. No monthly bill. Free forever with unlimited exports — pay once to remove the watermark.

WHY SUBTEXT • On-device transcription with word-level timing — your footage never leaves your phone • Import to styled export in under a minute, even on airplane mode • Three current caption looks: bold karaoke highlight, word-pop, and a clean line fade • A transcript-first editor built for the 90-second workflow: tap a word to fix it, hold to emphasize • Confidence review jumps you straight to the words worth checking • One-tap filler-word sweep removes every "um" from your captions • Platform safe-zone guides so captions never sit under the like button • Save your brand style once, apply it on every future clip in a tap • Burned-in export up to 4K, plus .srt / .vtt sidecar files

PRIVATE BY DESIGN Everything happens on your device. No account, no upload, no analytics on your content.

PAY ONCE The full pipeline is free with unlimited exports — each carries a small Subtext watermark. A single one-time purchase removes the watermark and unlocks style presets, filler sweep, and sidecar captions. No subscription, ever.
