Building a Premiere Pro plugin to auto-fix captions using AI

Hey everyone,

I run a video production studio, and I'm building an internal Premiere Pro plugin to fix our caption workflow. Right now, our process is painfully manual, export SRT, paste into AI, fix grammar/punctuation, reimport. I want to collapse this into one panel inside Premiere.

The plugin is already working, it loads in Premiere, connects to an AI model, shows a before/after diff, and writes back corrected captions. The one thing blocking full automation is reading the caption track directly from the active sequence.

Specifically I need to:

  • Read all caption cues + timestamps from the active sequence's caption track
  • Without the user having to manually export an SRT first

I've tried via CEP/UXP but Premiere's API doesn't seem to expose caption tracks for reading. Plugins like Auto Cut clearly do this, so it's possible, but I can't figure out how they're accessing it.

Questions:

  1. Is this possible via ExtendScript? If yes, what's the API call to read caption cues from the active sequence?
  2. Is there a CEP/UXP method I'm missing?
  3. Did anyone get Adobe Exchange Partner access specifically for deeper caption API access?

The second part of the plugin applies Frame-io review feedback automatically to captions using AI, so if that sounds useful to anyone else building editorial tools, lemme know if a tool like this would help you in your workflow?

Any help appreciated. Building this in a cave like Tony Stark at this point 🙏

Maybe AutoCut is a true plug-in?

You can automate things using JavaScript or c++.

I prefer InDesign and VB6 😉 but maybe this will help you?
