Sudowrite

You paste in a scene, a premise or a stuck paragraph, and Sudowrite gives back drafts, rewrites, outlines, character ideas or feedback to work from.

Sudowrite is an AI writing assistant built for fiction, including novels and screenplays, with tools for brainstorming, drafting, editing and feedback.

It runs on several AI models, so you can get different kinds of output for the same prompt, which helps when you hit writer's block.

Sudowrite says it does not claim ownership of what you write, and cancelling is easy.

Credits roll over for 12 months on the Max plan.

The catches: full AI features need a paid plan once the trial ends, some features may fall back on English when the language is unclear, and the tool can be pushed into plagiarizing if you explicitly tell it to, which its terms forbid.
