Free trial provides their Writer Assistant. Subscription $9 per month Basic Plan adds Mac 'expert' and images generator. Subscription $29 per month Pro Plan adds the coding assistant. Each level provides "Credits", apparently requiring further payment when they run out. - -> My usual comments about "AI": Today's marketing hyped "AI" systems are actually an advanced Expert Systems that traverse databases in search of responses to queries. As such, they're only as good as their database and are deliberately limited in their learning abilities, despite the 'machine learning' hype. (Why they're limited is a long discussion). "AI" creates nothing. It's all up to the database, how it is accessed, and how the gathered data is interpreted and presented to the user. With time, I could see "AI" being useful for fast and high quality responses to well defined queries. Considering the generally low quality of human support in our post-COVID era, there is potential for "AI" usefulness. - - Note that the results of any "AI" are specifically the responsibility of the programmers who made and sustain it. Again, "AI" creates nothing, ever. It's all about the code of the coders. Skynet will be hackable.
