Sudowrite

Sudowrite is built for fiction writers rather than for business copy. Its tools work on a manuscript in progress: it can continue a scene in your style, suggest descriptions that use the five senses, rewrite a passage with a different tone, brainstorm names, plot turns or character traits, and give feedback on a chapter.

A story planning area lets you keep a synopsis, characters and world details that the AI refers back to when it drafts, so suggestions stay closer to your book. You work in its own browser-based editor.

Writers split on how much to use it. Some take only brainstorming and description help and write every sentence themselves; others draft with it and revise heavily. If you plan to publish, check your publisher's and platform's current rules on AI-assisted writing, since some ask you to disclose it.
