Sudowrite

Sudowrite is written for fiction, which is what separates it from the marketing copy generators: it holds characters and plot state, suggests where a scene could go, and rewrites a paragraph in a described voice. Story Bible keeps a long manuscript consistent. Everything runs on credits, so a heavy drafting month costs more than a light one.

Three plans at $10, $22 and $44 a month, separated only by the monthly credit allowance, with up to 50 percent off annual billing. Every card offers a free trial, though no length is printed. There is no free plan. The credit model means the useful question is how many words a month you draft, rather than which features each tier holds.

Novelists and long-form fiction writers who want a drafting partner for the stuck parts. Anybody writing scripts for video will find the story machinery aimed elsewhere.
