When you visit the Google’s chatbot bard’s website in Microsoft Bing. A New Button pops up besides the search bar which lets you compare bard results with Bing chat’s. I have no idea why they implemented this, well maybe to show off the their chatbot is better than bard or something?
Sounds pretty helpful to me. Like really old first-generation Opera when it was really proud of its ability to search like 15 different search engines by putting g or b or w or y or whatever in the address bar before typing a search query or when it had still had its own built-in email program
