I'm currently building something like this, basically converting every service to a standardized API that you can consume in a structured manner. Not focused on AI, but focused on normal users with special requirements on usability.

Basically the ad blocking approach has failed, and one needs to recognize that an allow-list based approach is needed when consuming internet-based offerings. Pick the cherries out of each website, leave the trash behind, and then build a custom per-website GUI around the things that you actually want to consume.
