I have a company ChatGPT account, and a separate than my main account for Gemini. While there is an increased dependency on these tools with a growing merit to it, there's always the question of privacy with big tech companies. With an addon that pops up on every highlighted text, and knows my google account the second I open it's panel from my session on other pages, I think it's fair to ask the question whether this is the best way to go about implementing a feature like this. I don't know how much of the page I'm visiting is sent over to the service provider, but it's not obvious as an outsider. It could be a useful feature, but I don't think I will use it in this form, instead wait for a more isolated solution.
