Add subtitles to your YouTube Shorts, automatically

Turn your Short into a captioned video in minutes — word-by-word subtitles timed to your voice, burned in or exported as an .srt for YouTube.

Why subtitles matter on Shorts

Shorts are watched fast and often muted, and YouTube reads text to understand and recommend your video. Burned-in, word-by-word subtitles keep viewers watching to the end — the single biggest driver of Shorts reach — and a clean .srt helps YouTube index what you said. Both come out of the same upload.

How to add captions to a YouTube Short

1. Upload your Short and pick Hinglish or your language. Paste your script if you have one.
2. Style it. Every word is already timed — pick one of 56 looks and fix any word or caption.
3. Export a 9:16 video at up to 4K, or a plain .srt file to upload to YouTube — both from your browser.

Everything you get

Word-by-word timing

Each word appears exactly as it is said — the karaoke style that holds viewers — not a whole line at once.

56 caption styles

Pop-ins, boxed and outlined looks. Pick one, then change the font, colour, size and position.

The key word, emphasised

One word per caption is highlighted — numbers, money, power words — with an optional emoji and a quick zoom.

Paste your script

Have the script? Paste it before transcribing and the captions follow your spelling, timed to your voice.

Cleaner voice, music underneath

One switch removes hiss and room noise and sets the volume Instagram and YouTube expect; add music and it ducks under your voice.

Export up to 4K, or .srt

720p, 1080p or 4K made in your own browser, or an .srt file for any other editor.
