My biggest gripe so far with Janitor AI is how short of a memory span the AI seems to have. You may introduce a character at some point, spend a lot of time with that character present, the character leaves, and when you bring the character back 20 prompts later, the introduce themselves like they had never met you. Other times, specific things happened with a character, and 10 prompts or less later, that character don't remember those things or have a completely wrong recollection. Heck, I've had a character break into my house, and 5 prompts later, when recounting the events, they describe it as I having invented them over.Sure they exists. The Janitor one mentioned earlier is one of them.
Novel.ai and kobold.ai are generators you have to download or pay to, but those are really got at making stories, not just a typical chat bot back and forth, but actuall stories.
Also perchance has no limit at all with it's story generations.
I'm not familial with Novel.ai, Kobold.ai and Perchance. Do any of them keep better track of chat/prompt history?
