This seems, at present, to fundamentally be an interface to a bunch of custom prompts: select "write a press release", or whatever, click some dropdowns, click "write".

The "chat" extension is truly useless - no settings whatsoever and it can't 'read' any webpages content OR anything you're writing in writeseed ("wait, what's it for then?", "to chat with CGPT", wait, what?). No idea if there're plans to make it useful, coz creator didn't reply to Q's regarding.

Also no answers re missing advertised functionality, nor a response to suggestions to add any kind of support link for logged in users, instead of having to go to the "homepage" (which u can't go to by clicking the logo, so would have to do so by typing writeseed.com manually) - u can't make this stuff up.
If that doesn't give u a sense of the kind of product support to expect here, I don't know what will.

I don't know if the advertised SEO writing features were as advertised (giving an additional taco for benefit of the doubt), coz I wont be spending any more time here.
