Reelsub in action

A short walkthrough: from uploading a clip to finished captions in a couple of minutes.

Ready in a minute

Upload a clip, get a finished video with captions back. No editing, no typing it out, no overnight render.

Word-by-word highlight

Every word lights up exactly as it's spoken. Viewers follow the text and watch to the end — and that's a signal to the algorithm.

Styles built for the platform

Ready-made presets for Reels, TikTok, Shorts and podcasts. Font, size, colors and animations tweakable in a couple of clicks.
