Your words, with an editor beside you
Where Writing Desk differs from Sudowrite, from who writes the words to how the finished book comes out.
Sudowrite is built to draft and rewrite prose with you, so the sentences on the page come from both of you.
The AI reviews but never writes, so every sentence is yours.
Sudowrite runs in your browser, so you write online and your project lives in an online service.
A distraction-free editor in a native Mac app that works fully offline. Your manuscript is stored on your Mac. AI calls are made transiently and your words are never used to train models.
Planning runs through Story Engine and a story bible, built to feed the AI.
Story planning tools are built in and do not rely on AI: eleven structure templates in the Story Plotter, a Story Board, a Timeline and a Resource Hub for characters, locations, lore and factions.
Sudowrite's tools are AI features, and each use draws on your credits.
Fiction-specific spelling and grammar checks and Prose Analysis run on your Mac, with no AI and no usage limit.
Export covers DOCX and plain text.
Export .docx, .md, .txt or .pdf, then typeset an EPUB and print PDF in Formatter, with the fonts, drop caps and scene breaks you choose.
There is no ongoing free plan after a small trial, and credit-metered use can run out quickly when you generate a lot.
Start on a free plan with a 30-day Premium trial. Paid plans include AI credits, with top-ups when you need them.
Converting a .docx or .md document to a .wddoc project makes a copy and leaves your original file as it is. How it works
