Question: Can you recommend a platform that allows me to collaborate with AI characters to write novels or creative stories?

If you want a platform to coauthor novels or other creative stories with AI characters, NovelAI is a good option. The subscription-based service uses AI to create authors and stories, with tools to generate images for characters, a text adventure module and customizable editing tools. With different pricing levels, NovelAI accommodates different levels of text generation and memory, so you can use it for whatever kind of writing you want.

Another option is StoryNest.ai, which offers a variety of tools to craft compelling stories and novels. That includes character creation and world-building tools, as well as AI-assisted editing and proofreading. The service can handle multiple formats, including interactive fiction and scripts, and you can collaborate with both AI and human writers. You can sign up for a free account to try its tools, but more detailed pricing information is on the website.

Backyard AI offers a text adventure and interactive storytelling experience with AI characters. It offers offline and online modes, a privacy focus and the ability to run AI models directly on your own desktop. The service works on a wide range of hardware and offers features like data encryption, automatic GPU acceleration and secure cloud models. It has a few pricing levels to choose from.

For a full-featured writing environment, Novelcrafter is a more powerful tool with a personal wiki to house story details, multiple writing modes and AI writing assistance. It also offers outlining tools, revision history and customizable tags, so it's good for both planners and pantsers. Novelcrafter has four pricing levels and a free trial, so you can find the right level for your needs.
