It works pretty well provided you're logged into the right Google account.
However, I have a SERIOUS concern - this extension sends ALL searches to Bard. If I want some privacy and use, say, DuckDuckGo then bard still pops up which means that my private query has been sent to the Google team.
This is a big no for me, so I'm uninstalling it.

Does what it says it does, but has a button that links to pay the creator monthly, to just link to the bard site to continue the convo, i do not see how paying the creator of this said plugin does anything other than give you a link.

Very interesting idea, but does not seem to work properly inside a Firefox container. It constanly displays "Login to Google" while I am logged in within the container.
There is also a privacy risk: while in Private Browsing mode, clicking on "Login to Google" opens a new window in the non-Private Browsing mode, making you unexpectedly leave the Private Browsing mode.
