Auto Captions for TikTok — Bold, Animated, Free

The captions that keep people watching: big, centred, two words at a time, each word popping in as it's spoken. Drop in your TikTok, fix any word, and download it ready to post — no app, no account and no watermark.

1 · Your video

The first run downloads the speech model and keeps it in your browser, so the next videos start straight away.

3 · Caption style

Why this style works on TikTok

Quick answers

Will the captions be cut off by TikTok's buttons?

The style is centred in the middle of the frame, away from the side buttons and the bottom caption bar.

Is there a watermark?

No watermark, ever.

Can I caption Arabic TikToks?

Yes — set the spoken language to Arabic. The text is laid out right-to-left automatically.

How it works

  1. Pick your video. Nothing is uploaded — the audio is read and transcribed on your phone or computer.
  2. Press Generate subtitles. Whisper, an open speech-recognition model, writes down every word with its timing.
  3. Tap any line to jump to it and correct a word. Timing stays in sync.
  4. Choose a style and download the MP4 with the captions burned in, or an .srt for YouTube, CapCut or Premiere.

Frequently asked questions

Is it really free?

Yes — no sign-up, no watermark, no limits on the number of videos.

Is my video uploaded?

No. Speech recognition and video rendering both run on your device. Only the speech model itself is downloaded once.

How accurate is the Arabic?

Clear Modern Standard Arabic comes out well; strong dialects and background music lower the accuracy, so review the text before exporting. “Best” accuracy helps.

How long does it take?

Roughly real time for transcription on a laptop with “Fast”, and about the length of the video to render. Phones are slower.
