How it works
How word-by-word animated captions work
Our AI transcribes your video's audio and timestamps every individual word with millisecond precision. As your video plays, each word highlights, bolds, changes color, or animates exactly as it's spoken, creating a synchronized reading experience.
This word-level timing is what separates basic captions from the animated styles used by top creators like Alex Hormozi, Steven Bartlett, and MrBeast. The technique is proven to hold viewer attention and increase watch time.
Why word-by-word
Why word-by-word captions outperform static text
Word-by-word animation turns passive viewers into active readers. When each word highlights in sync with speech, viewers subconsciously follow along, increasing comprehension and keeping eyes on screen 40% longer than static captions.
This effect is especially powerful on short-form platforms where you have 1-2 seconds to hook a viewer. Animated captions create visual movement that stops the scroll and keeps people watching through your entire clip.
Precision
How precise is word-level timing?
Our AI timestamps each word within 50 milliseconds of when it's spoken, ensuring animations feel perfectly in sync with the audio. The system handles fast speech, pauses, emphasis, and natural rhythm without manual adjustment.
You can fine-tune timing for any individual word if needed, but most creators export without any edits because the AI timing is accurate enough out of the box.

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."
