Sudowrite

Sudowrite is an AI writing tool aimed squarely at fiction. The vendor is explicit that its chat was built with novelists in mind rather than engineers, and the whole product is organised around the problems of writing a long narrative rather than producing marketing copy. Story Bible is the backbone: it takes a writer from an initial idea to an outline, then to beats for individual chapters, then out to thousands of words, working in the writer's own style rather than a generic voice.

The drafting tools address specific stalls. Write functions as an aggressive autocomplete, analysing existing characters, tone and plot arc before suggesting the next 300 words in the writer's voice, and it offers several options rather than a single continuation. Describe generates sensory description so that prose built only from action and dialogue does not read flat. Expand lengthens a passage where pacing has run too fast, which is the opposite problem to the one most AI writing tools solve.

Editing gets equal weight, on the vendor's own argument that writing is a small fraction of the work and editing is most of it. Rewrite produces alternative versions of a sentence rather than making the writer produce them by hand, and higher tiers add feedback on the work itself. Plans are published at three levels with a free trial that needs no credit card, and yearly billing is discounted.
