How it works
How does auto caption generation work?
Our auto caption generator processes your video in three stages: first it extracts the audio track, then AI speech recognition converts spoken words into text with precise timestamps, and finally captions are formatted and overlaid onto your video.
The entire process is hands-free. You don't need to type a single word, adjust any timing, or manually sync anything. The AI handles language detection, punctuation, speaker changes, and caption formatting automatically.
Why auto captions
Why use an auto caption generator instead of manual captioning?
Manual captioning takes 4-6 hours per hour of video and requires painstaking timing adjustments. Our auto caption generator does the same work in under 2 minutes with 97%+ accuracy, freeing you to focus on creating content instead of transcribing it.
Auto-generated captions also ensure consistency across all your videos. Every caption follows the same style, timing, and formatting rules without human error or fatigue.
Accuracy
How accurate are auto-generated captions?
Our auto caption generator achieves 97%+ accuracy on clear audio, rivaling professional human captioners. The AI is trained on millions of hours of real-world audio including podcasts, vlogs, interviews, and presentations with background noise.
You can review and edit any caption before exporting. The built-in editor lets you fix the rare error in seconds rather than 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"

"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."
