HN may not be the target audience for this feature, but I've absolutely proposed writing a browser extension to synthesize confidential search results with public search results before, because it's a need that remains unmet to this day. If Bing is integrating their confidential cloud with logged-in search, that is a game-changer. I hope everyone gets past the visceral reaction against it and starts building browser extensions that compete. It is possible to do this without depending on a single search engine to perform synthesis for you. Metacrawler can live again.
