How it works
How our free closed captioning software works
Upload any video and our AI-powered closed captioning software automatically transcribes the audio, segments it into readable caption blocks, and generates an industry-standard caption file. The AI handles punctuation, timing, and line breaks so captions display comfortably on screen.
The tool produces SRT and VTT files that meet accessibility standards and work with every major video platform including YouTube, Vimeo, Facebook, and professional broadcast systems.
Accessibility
Why closed captioning matters for accessibility and compliance
Closed captions make your video content accessible to 466 million people worldwide with hearing disabilities. Beyond accessibility, captions are legally required for many types of video content under the ADA, Section 508, and similar regulations in other countries.
Our free closed captioning software helps you meet these requirements without expensive professional captioning services. The AI-generated captions achieve broadcast-quality accuracy at zero cost.
Quality
How accurate is AI closed captioning?
Our closed captioning software achieves 97%+ accuracy on clear audio, meeting the FCC's quality threshold for broadcast closed captions. The AI handles multiple speakers, technical terminology, and various accents while maintaining proper grammar and punctuation.
Every caption is reviewed before export with an easy editing interface. Fix the rare error in seconds instead of building captions from scratch.

"All these random startups and VC-backed companies going after the "creator economy". Now this is how you do it. For creators, built by creators. Super bullish on products being built for the pain points already felt deeply by the founder. Let's goooooo!"

"After a few small technical issues the team really went above and beyond to help. They were fast and efficient and really made all the difference. I don’t think I have had this type of customer service … maybe ever lol - Thank you and recommend"

"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."
