How it works
How to add captions to Instagram videos and Reels
Upload any video and our AI automatically transcribes the audio, generates perfectly timed captions, and formats everything for Instagram's 9:16 vertical format. The captions are burned directly into your video so they always display correctly.
Unlike Instagram's built-in auto-captions which disappear when viewers turn them off, burned-in captions are always visible and styled exactly how you want them. This gives you complete control over your content's appearance.
Why caption Instagram videos
Why captions are essential for Instagram engagement
92% of Instagram users watch videos with the sound off. Without captions, your message doesn't land with the vast majority of your audience. Adding captions to Instagram videos increases average watch time by 40% and significantly boosts saves and shares.
Instagram's algorithm rewards content that keeps people watching. Captions hold attention by giving viewers a reason to stay even when they can't or won't turn on audio.
Quality
How accurate are AI captions for Instagram videos?
Our caption generator achieves 97%+ accuracy on clear audio and is specifically optimized for the fast-paced, music-heavy content common on Instagram. The AI handles voiceovers, on-camera speech, and even content with trending audio playing in the background.
Captions are positioned to avoid Instagram's UI elements, so text never gets cut off by the like button, comments section, or username overlay.

"The Choppity team have been shipping new updates to the product which I am quite happy about. It's getting faster and they are also giving us the features we've been asking for!"
Amy L.
Finance creator
"In the past I've tried to get my YouTube video editor to create mass amount of short form content, but they struggled. Economically it didn't make sense and the quality wasn't great. Choppity has been an INCREDIBLE asset in scaling up my short-form video reach. Having ALL the clips automatically clipped, styled and ready to publish has been the biggest lever to growing my businesses."
