That's really a time saver — I've been using ChatGPT for a while and switching other extensions didn't work so well. Tried cmdj today and that's much better.
Small feedback: I couldn't figure out how to make ChatGPT track context so it would be within the same question I asked before — seems like the extension creating a new context for each question? Is it supported right now? Maybe some hint of what dialog is happening with ChatGPT right now?
As of my last update in January 2022, there isn't a specific extension called "Cmd J – ChatGPT for Chrome." However, it's possible that such an extension may have been developed after my last update.
