Novel.ai comes to mind. It’s made for writing. It won’t write for you, but it’s better in some ways than the more general purpose AIs you named. I mean, it still needs editing and human input.
The interface is made for that, too. You can just edit the story like you can’t in typical chatbot interfaces. Pacing and omniscience are still a problem, but it does follow specific instructions better. You have lorebooks for specific details. And a very workable amount of tokens

I don’t have an immediate need for this, but I could see it in the future when I upgrade some local hardware. That being said +1 for Podman support.
