What AI tool is good as "dungeon master" for rol games nowadays?

A few years ago, AI Dungeon used to be a very cool and interesting tool for this purpose, but very limited in many aspects.

When ChatGPT was released, AI dungeon felt obsoleted. But then again, ChatGPT wasnt that good at remembering events from the past.

Nowadays, if Im bored and want to have a quick campaing, what AI tool you guys recommend and what tips can you give me?

Thank you!
