The problem it solves

Adding captions by hand means transcribing every word and timing it to match the video, which takes far longer than actually making the content. Videos without captions also lose viewers who watch on mute or need accessibility support. This gets you captioned video automatically, without touching an editing timeline.

Who it fits

Content creators, marketers, or educators who publish video regularly and want captions without manual editing.

How it works

  1. You submit a link to a publicly accessible video
  2. The request is sent to json2video, where AI analyzes the audio and generates captions
  3. The system checks in periodically until the captioned video is ready
  4. You receive a link to the final video with captions burned in

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
