I foreseen this a couple years ago. We already have web search tools in LLMs, and they are amazing when they chain multiple searches. But Spegel is a completely different take.

I think the ad blocker of the future will be a local LLM, small and efficient. Want to sort your timeline chronologically? Or want a different UI? Want some things removed, and others promoted? Hide low quality comments in a thread? All are possible with LLM in the middle, in either agent or proxy mode.

I bet this will be unpleasant for advertisers.
