Add captions to your Instagram Reels — free
Captions are what keep a Reel watched to the end — most people scroll with the sound off. AI Caption Cut adds them in the trending, animated, word-by-word style, generated right in your browser. No upload, no account, no monthly plan.
The styles that actually go viral
The look matters as much as the words. There are 30+ caption templates built for short-form: bold pops that punch one word at a time, karaoke highlighting, cinematic hero words, boxed accents — the styles you see on the Reels that perform.
Every one is adjustable: font, colour, size, position and a per-word accent font, so your Reels have a consistent look instead of a generic template.
Built for vertical
Reels are 9:16. You can crop any footage to vertical, drag the captions exactly where you want them (clear of the caption bar and the like/comment icons), and preview the finished frame before you export.
Export is a clean MP4 you post yourself — free at 480p with a small watermark, or watermark-free HD from a one-off ₹39.
Free, and nothing is uploaded
Your Reel is captioned on your own phone or laptop — the file never leaves it. That means no upload wait, no file-size cap, and no footage sitting on someone’s server.
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 an Instagram Reel for free?
Open AI Caption Cut in your browser, add your video, and captions are generated on your device automatically. Style them, drag them into place, and export an MP4 to post. Free exports are 480p with a small watermark; removing it is a one-off ₹39.
Do the captions have a watermark?
Free 480p exports carry a small watermark. A one-off payment per video (₹39 for 720p, ₹59 for 1080p) removes it — with no subscription.
Does it upload my Reel anywhere?
No. Everything runs in your browser on your own device. Your video is never uploaded, which is also why there is no file-size limit.
Can I caption Reels on my phone?
Yes. It works on Android and iPhone browsers, with a mobile editor layout, and can be installed to your home screen like an app.
