I don't have it on the Chrome store yet (I'm not sure if they'll allow it) but you can pull down the code and install it into Chrome yourself, then just add your OpenAI API key (stored locally).
The way it works is pretty simple, it inspects the DOM for suspected ads, verifies using the gpt-4o-mini model and if it is indeed an ad, it simply gets removed from the DOM
From my admittedly limited testing, it's working pretty well, but feel free to suggest any improvements to the code or submit a PR
Hope someone finds this useful
