AI Captions: Word-by-Word Subtitles in Viral Creator Styles
VdoBloom AI Captions turns a talking video into a captioned short. Upload a clip up to three minutes long, and the AI transcribes every spoken word with its exact timing, so each word lights up on screen the moment it is said.
Fix any word before rendering, then choose a look: a bold pill behind the spoken word, huge comic captions, one word at a time, a karaoke fill, emoji accents, coloured key words or a clean minimal line. Keep the original shape, or resize a landscape video to 9:16 while the crop follows whoever is talking.

Every line is editable. Words you keep keep their exact timing; rewritten lines are re-timed across the same moment.

Pick a style and a shape
Choose one of seven caption styles, keep the shape or go vertical with follow-face, blur fill or a two-speaker stack, and add zoom punch-ins if you like.

Render and download
The captions are burned into an mp4 ready for Reels, TikTok and Shorts. Several renders are included, so you can try another style.
Frequently asked questions
How accurate are the word timings?
Each word is transcribed with its own start and end time, and the highlight moves on those times, so captions stay in sync with the voice even after silences are cut.
Can it make my landscape video vertical?
Yes. The vertical options detect faces and follow the person speaking, fill the frame with a blurred copy of the video, or stack two speakers top and bottom.
What does jump cut do?
It removes silent pauses and keeps a short margin around every word, so the video feels tighter without clipping speech. Caption timings are moved to match.
How is it priced?
Transcription is charged per minute of video, and a few renders are included in that price so you can try different styles.
