Word-by-word captions for Reels, TikTok and Shorts
Most short-form video is watched with the sound off. Upload your clip and get bold captions where each word lights up the moment it is spoken — the style viewers expect, without keyframing a single word by hand.

What you get
Word-level timing
Each word is timed individually from the speech, so the highlight follows the voice instead of a whole line flashing at once.
Four looks
Word-by-word highlight, clean white, white on a dark plate, or classic yellow — at the bottom, middle or top of the frame.
Readable on a phone
Short caption chunks, sized as a share of the frame height, so they stay legible on a 6-inch screen.
Pairs with auto-edit
Cut silences and filler words first, then caption the tightened cut — in the same studio.
Same thing over the API
One header, one multipart request with the file, then poll the job or take a webhook. The same operation you just tried in the browser.
Questions
Does it work for vertical 9:16 video?
Yes. Caption size and margins scale with the frame, so they fit vertical and horizontal video alike.
Which languages are supported?
Speech recognition covers about a hundred languages, including English, Ukrainian, Russian, Polish, German and Spanish.
Can I fix a misheard word?
Yes. Recognise first, correct the text in the editor, then burn the corrected captions.
Can I automate this for many clips?
Yes — the same operation is available over the REST API, so a script or an AI agent can caption a whole folder.
