AI transcribes audio

How it works
How to automatically generate subtitles for any video
Upload your video and our AI extracts the audio, converts speech to text, and formats everything into properly timed subtitle segments. The tool handles punctuation, line breaks, and reading speed automatically so subtitles are comfortable to read.
You can download subtitles as SRT or VTT files to upload alongside your video, or burn them directly into the video file itself. Both options are free.
Why auto subtitles
Why use an auto subtitle generator?
Creating subtitles manually takes 4-6 hours per hour of video. Our auto subtitle generator does it in under 2 minutes. The AI handles timing, punctuation, and formatting that would otherwise require specialized software and tedious frame-by-frame adjustment.
Subtitles increase video engagement by up to 80%, make your content accessible to global audiences, and improve SEO by giving search engines indexable text.
Formats
What subtitle formats does the auto generator support?
Our auto subtitle generator outputs industry-standard SRT and WebVTT files that work with every major video platform and editing tool. SRT files are compatible with YouTube, Vimeo, Facebook, and all professional editors. VTT files work with web video players and HTML5.
You can also burn subtitles directly into the video with custom styling, which is ideal for social media platforms where separate subtitle files aren't supported.

"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."
