I haven’t tried it recently, but I’ve been told Perchance took a major step backwards in quality last year. I suspected they turned down the processing available for each prompt.
I haven’t found any AIs are any good for writing fiction. You see phrase patterns, odd grammar and poor descriptive word choices, repeated over and over. Any experienced writer will spot them very quickly, and that’s before the continuity errors and poor understanding of physics and hierarchies (He removed his hat, revealing his T-shirt etc.).
All of the ones I’ve tried are better now than last year, BUT there is a storm coming. A lot of the stuff they are learning from is AI generated, so these mistakes and faults are being fed back into the system. This is a feedback loop of junk in the system and I can’t see how it won’t just cause it all to deteriorate again.
