Any are welcome, so far as I know having not checked their submission criteria, to spin it up and contribute tags to the SponsorBlock community. I'd wager there are people already doing so.

I think it would be more useful to more people to utilize the existing solution because it runs in a very small footprint for the end user. Most people wouldn't be able to run an entire TTS/LLM workflow without processing videos in the background or waiting some multiple of real-time in order to watch a video.

You could maybe do it with just LLM tagging the transcript, but that's still a ton of processing just to watch a video.

God that'd be so much wasted energy if every person wanting to skip in-video ads was running an entire LLM to do so.
