Caption App for iPhone: Auto Subtitles in One Tap
BlitzCut is a caption app for iPhone that transcribes your video without uploading it and burns in word-by-word animated subtitles — styled like the captions top creators use, without a cloud upload.
Most iPhone caption apps either transcribe poorly, watermark the export, run everything through a slow cloud server, or give you plain subtitle text that looks nothing like the animated captions performing on TikTok and Reels.
BlitzCut generates captions on your iPhone in seconds — accurate word timings, creator-style presets like bold Hormozi captions or clean minimal subtitles, and full control of font, size, color, and placement. Captions burn into the export, ready for any platform.

Frequently asked questions

- BlitzCut adds subtitles automatically: import a video, and the transcription, word timing, and styled captions happen in one pass — no video upload, no waiting on a render queue.
- Are the captions accurate?
- Transcription handles clear speech very well, including accented English. When a word is misheard, tap it and type the fix — the timing adjusts automatically.
- Does BlitzCut watermark exports?
- No watermark. During the free 3-day trial you get the full experience; paid plans start at $6.99/week after.
- Who is this not for?
