A reflective writing environment that turns your ideas into finished prose — by talking or typing — while preserving your voice and sharpening your thinking.
The whole authoring loop, in one calm workspace.
A conversational writing partner that asks before it answers — developing your thinking instead of writing for you. Flip to Discernment mode when you want it to stress-test an idea.
Don't feel like typing? Get a chapter-shaped set of interview questions, talk your answers, and watch them become clean prose in your voice — with a human approval gate before anything is final.
Your structure evolves as you write; recurring themes and tensions surface on the side and can be promoted into chapters.
Find quotes, stats, and references that strengthen your point — every quote verified against its real source, so nothing fabricated slips in.
Flag passages that echo published work and rephrase them in your own voice — protecting the thing that makes your book yours.
Opt into NRSI personalization and the workspace adapts its pacing, prompts, and structure to your authoring style — never a verdict, always reversible.
From idea to finished chapter.
Sketch your book's parts, chapters, and themes in the Living Book Map.
Work a chapter in the Flow Space — or talk it out with dictation.
Turn it into prose in your voice; add verified sources; check originality.
You review and approve every AI-shaped draft before it's final.
Free to think. Upgrade to scale and ship. Every new account starts with a 14-day full-feature trial.
No. Author OS is built to develop your thinking and preserve your voice. At its core it asks questions rather than writing for you; even dictation shapes your own spoken words into prose, and you approve everything.
You get a chapter-shaped interview script, you talk your answers aloud, and the system transcribes and shapes them into prose in your voice — then a human (you) approves before publish.
An optional, consent-based layer that adapts the workspace's pacing, prompts, and structure to how you author. It only changes the experience — never gates features — and you can turn it off and delete it anytime.
Your projects and transcripts are yours. NRSI data is opt-in and hard-deleted on withdrawal.
