I don't get it. The service seems to use Groq and OpenAI as the 'assistant' somehow. Logging in and clicking the 'Profile' button on the top right flashes a new page that promptly collapses.

It looks like this is a Chrome extension? If so, it is only browser based and that isn't mentioned anywhere on the site until I presume you hand over your USD4.50 for one month payment.

To me this seems borderline dishonest by omitting it is browser - and Chrome at that - based only. If there was a free way to try it, I'd know more but I'm not paying money to be disappointed. Buyer beware, I guess.
