Long-form use case

Novel writing use case

For novelists and serial fiction writers: keep characters, world-building, outline, chapters, and review in one project. AI can draft and revise, but every important change enters Diff review before it becomes manuscript.

Who it is for

Serial fiction writers

Maintain characters, world rules, foreshadowing, and chapter rhythm across a long project.

Writers with scattered notes

Turn character cards, outline fragments, and style notes into reusable project context.

AI-assisted writers who want control

Inspect the exact change before accepting it instead of letting AI overwrite the draft.

Writers preparing export or publication

Move from source material to draft, review, and Markdown/Web export without switching tools.
