Automatic caption generator

Automatic caption generator with true word-by-word sync

Zupum transcribes your video from the audio itself, then highlights each word exactly as you say it - the karaoke effect short-form audiences expect, generated automatically and burned into the export.

Caption my videoSee everything Zupum does

Captions that match the lips

Line-level subtitles drift and read as an afterthought. Zupum times captions at the word level from the audio, so the highlight lands on the spoken word rather than roughly near it.

  • Word-level timestamps from acoustic transcription, not guesses
  • 90 caption styles across bold creator, clean and editorial looks
  • Custom fonts, sizes, colours, outlines and shadows
  • Drag captions anywhere in the frame; the position applies everywhere
  • Sync nudge slider for frame-level correction
  • Filler words like um and aah removed from both audio and captions

Styling is retention, not decoration

Pick a style before the edit starts or switch it mid-edit and watch the whole video restyle instantly - useful for testing which look holds your audience.

The same transcript powers the rest of the edit

B-roll placement, sound effects and hook text all come from the same transcript, so your captions and visuals reinforce each other instead of being two separate jobs.

questions

Frequently asked

Are the captions word-synced or line-by-line?

Word-synced. Timings come from acoustic transcription, so each word highlights exactly as it is spoken instead of a whole line appearing at once.

How many caption styles are there?

90 styles, spanning bold creator looks, clean minimal subtitles and editorial styles, with control over font, size, colour, outline and shadow.

Can I move the captions?

Drag them up or down in the preview and the position applies across the whole video. A sync nudge slider handles frame-level correction.

Do captions get burned into the export?

Yes - captions are rendered into the exported MP4, MOV, WebM or MKV so they display everywhere you post.
