Caption your YouTube Shorts — free
Shorts are watched fast and often muted, so on-screen captions do the heavy lifting. AI Caption Cut generates styled, animated captions for your Shorts in the browser — free, on your device, with no sign-up.
Made for fast, muted viewing
Captions are generated with word-level timing and highlight one word at a time, which is what holds attention on a Short. Choose a punchy template, size the text big enough to read on a phone, and place it where it will not clash with the Shorts UI.
Everything is editable — every word, and every style detail — so it reads clean and matches your channel.
Long recording? Cut it into a Short
Shorts often start as a clip of something longer. There is no length limit on the source video, so you can caption a full recording and trim it down to the Short you want, then export vertical 9:16.
The reason is architectural, not generous. Cloud caption tools rent GPUs by the minute, so every minute of your video costs them money — which is why their plans meter you by video length, upload size or credits. AI Caption Cut renders on your own device, so a longer video costs us nothing. There is no meter to run.
Free, private, no meter
Your video stays on your device — nothing is uploaded — and there is no cap on how many Shorts you caption.
AI Caption Cut is free to use with unlimited 480p exports that carry a small watermark. Removing the watermark is a one-off payment per video — ₹39 for 720p, ₹59 for 1080p (Full HD). There is no subscription and no account.
Questions
How do I add captions to a YouTube Short?
Add your clip to AI Caption Cut, let captions generate on your device, style and position them, then export a 9:16 MP4 to upload as a Short. Free at 480p with a small watermark; a one-off ₹39 removes it.
Does it upload my video to caption it?
No. Captioning runs in your browser on your own device, so the file is never uploaded and there is no size limit.
Can I caption a longer video and cut it into a Short?
Yes. There is no length limit on the source video, so you can caption the full recording and trim it to the Short you want before exporting.
