How it works
How to add captions to a YouTube video
Paste any YouTube video URL and our AI pulls the audio, transcribes every word, and overlays styled captions directly onto the video. You don't need to download anything first or use separate transcription and editing tools.
The captions are burned into the video itself, so they display perfectly on any device and platform without relying on YouTube's subtitle system. This is especially useful when you want to repurpose YouTube content for other platforms.
Why caption YouTube videos
Why should you add captions to YouTube videos?
YouTube videos with captions get 12% more views and significantly higher watch time. Captions make your content accessible when viewers can't use audio, whether they're in a quiet office, on public transport, or have hearing difficulties.
Captions also feed YouTube's search algorithm. While YouTube can auto-generate captions, they're often inaccurate. Providing clean, accurate captions helps YouTube understand your content and recommend it to the right audience.
Quality
How accurate are AI captions for YouTube videos?
Our AI delivers 97%+ accuracy on clear audio, far exceeding YouTube's built-in auto-captions which often miss punctuation, confuse similar-sounding words, and produce unreadable text.
The system handles long-form YouTube content like podcasts, tutorials, and interviews with multiple speakers. Each caption is timed at the word level for smooth animated reveals.

"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"

"We've been using Choppity for the last 6 months or so for the AutoTrader tech podcast. We've seen a massive increase in our views and subscribers! Couldn't have done it without Choppity."

"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."
