This sounds like something you could use LLMs for as LLMs are quite good at removing bias in content. You might run into context length issues feeding the whole transcript in though .

I think that would be insanely expensive. Perhaps could be possible for a few channels though.

Unless there was something like sampling, similar to how shazam recognising music from a few seconds works.

Could someone only get a portion of the content and, semi accurately generate a summary?

I have really wanted to make something like this for nestjs, but I haven't gotten around to it yet

Do it world needs more of these it is not 1 or 2 times when I have even started side project and almost all ways stop that annoying lets create app authentication,email sending, landing page, good style phase and don't even get to business logic step.
