Why this exists
More and more people ask an assistant instead of a search engine when they want a recommendation. The answer they get depends on which assistant they ask, and often on when they ask it. We put the same plain question to all four, with web search on, and show where the answers meet and where they don't.
We don't add our own pick, and we don't edit the answers. If an assistant says something wrong, that stays in the record. Read how we ask, or browse every question.
