I didn’t use a plug-in, but I am using the pay version. It did say it was accessing the web, including Wikipedia, which is generally accurate on that sort of thing. Listing the same name twice is hard to excuse.

You can get everything for free with Bing Chat on Edge. Very good with retail/commerce questions such as “find me a ski shell with lots of zippers”, and it often gives discounts/coupons.
I still use the paid version for professional work, but Bing is definitely worth exploring.
