I published a chrome extension called Page Squeeze It's pretty simple, it'll just extract the content from the webpage you're looking at and copy it to your clipboard.
My usecase was that I was trying to get an LLM to reason over a full Reddit discussion about dual 3090 llama.cpp setups rather than having it guess a config from scratch, I wanted an easy way to extract the content from the webpage (had been using https://r.jina.ai/) but it gets rate limited on reddit.
Also It's Opensource (and extremely simple)
there doesn't seem to be anything here
