ASK HN: Is there a self-hosted tool like Sudowrite or Novel.AI?

Have been working with FOOOCUS which does a great job of letting you creating images on a local box with fairly easy prompting and tuning. I'd like to find something similar for writing - where I can give an outline and characters and expect a chapter that actually respects both. SW and Novel.AI come close, but aren't cheap (especially with SW's new credit system), and are hard to train to "write like me". Anything out there?
