ScrollStop

Make Shorts, Reels and TikToks that stop the scroll, all in one place, for free.

Scrollstop turns your clip into a finished short: word-by-word animated captions, your voiceover, stickers, color fixes and music, then exports a version sized for each app.

Captions that get your words right

Scrollstop transcribes your video with OpenAI's Whisper speech model, running right in your browser. Fix any word by typing over it. Pick from bold pop, highlight box, word-by-word reveal or clean subtitle styles, and drag captions anywhere on screen.

Record your voiceover while the video plays

A 3-2-1 countdown, then talk. Re-record any part without starting over. Captions can be made from your voiceover automatically.

Stickers that point things out

Arrows, speech bubbles, a live zoom lens that magnifies what's under it, circles, big text and emoji. Drag, resize and rotate them on the preview.

Fix the picture

One-tap Auto fix, presets like Vivid and Moody, and sliders for brightness, contrast, warmth, sharpness and more. Great for footage with a green or blue color cast.

Music that steps aside when you talk

Add a song and Scrollstop lowers it automatically whenever you're speaking.

One export, sized for every app

TikTok, Reels and Shorts each cover different parts of the screen with buttons and text. Preview your video as each app sees it, and Scrollstop exports a separate version for each one with your captions moved clear of the buttons.

Private by design

Your video never leaves your computer. No account, no watermark, no upload.

Good to know

Works best in Chrome or Edge on a computer.

The first time you generate captions, the speech model downloads once (about 40 to 80 MB).

For voiceover recording and saving videos, use Open in new tab at the top of the tool.

Trending sounds from TikTok or YouTube can't be used outside those apps, so export without music and add the sound when you upload.
