Subtext: Auto Captions

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
• Choose the language spoken in your clip, and Subtext remembers it next time
• Caption in a different language from the speech — translated on your device, not in the cloud
• Bring your own .srt or .vtt subtitle file when you'd rather supply the text yourself
• 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. Choosing your spoken language and importing a subtitle file are free too. A single one-time purchase removes the watermark and unlocks translated captions, style presets, filler sweep, and sidecar captions. No subscription, ever.
