Write in a Click is a book writing app where Robin, its AI assistant and your story partner, reads your entire manuscript, your Story Hub and your voice profile, and answers in a chat panel beside the page. Robin never changes your manuscript on its own. In Edit Mode it can suggest changes, and nothing lands unless you keep it. Proofing runs when you ask it to, and changes only what you accept. Paid plans include optional tools that can draft a starting outline or cover art; nothing from them enters your chapters unless you choose it. The AI is spent on things that were not possible before: Reader Pulse scores every chapter for reader engagement and drop-off risk before a single human reads it, Draft from Book (the "Draft all from Book" button in the Story Hub) finds the characters, places and events your chapters already established and asks before adding them to the Story Hub, while a manuscript you import during onboarding fills the Story Hub directly, and your voice profile keeps Robin's feedback measured against how you write.
Each of these answers a question an author has always had, and has never had a fast or affordable way to answer.
“Where will a reader put my book down?”
Reader Pulse
Every chapter scored 0-100 for predicted engagement, with a drop-off risk of low, medium or high, and five sub-scores: opening hook, closing hook, pacing, tension and emotional resonance. At book level: your strongest and weakest chapter, the trend across the book, and the exact points a reader is most likely to abandon it.
Before this existed: A beta reader, four to eight weeks of waiting, and the hope that they are willing to be harsh with you.

Draft from Book
Reads your chapters for the characters, places, worlds, glossary terms and timeline events they have already established, diffs that against your Story Hub, and shows you what is missing. When you run it from the Story Hub, you approve each change individually, and anything you add can be undone straight after. A manuscript you import during onboarding is filed into the Story Hub directly.
Before this existed: Re-reading your own book with a notebook open.

“What does my prose actually sound like?”
Writing voice analysis
Your voice described back to you across five pillars — style, tone, point of view, perception and pacing. It exists so that everything Robin tells you is grounded in how you really write, and so that any change Robin suggests in Edit Mode stays close to your voice.
Before this existed: An editor you could afford to ask, or nothing.
Free: style, tone, POV · paid: all five
“When do I actually write well?”
Writing Insights
Streaks, a twelve-week heatmap, a best-hours histogram, seven-day velocity and a per-chapter breakdown. Not a word-count leaderboard — a picture of the conditions under which your own good days happen.
Before this existed: A vague feeling that mornings are better.

Why the AI can see this much
Other tools analyse a file you upload and hand back a report. Here the book already lives in the workspace, so the manuscript, the Story Hub and your voice profile are all live context — and the reading can be re-run as the book changes. There is nothing to export, nothing to re-brief, and nothing to keep in sync.
Does Write in a Click write my book for me?
No. Robin is AI: it reads your manuscript and answers in a chat panel. Robin never changes your manuscript on its own. In Edit Mode it can suggest changes, and nothing lands unless you keep it. Proofing runs when you ask it to, and changes only what you accept. Paid plans include optional tools that can draft a starting outline or cover art; nothing from them enters your chapters unless you choose it.
Will AI touch my manuscript at all?
Only when you keep a change. In Edit Mode, which you switch on, Robin can suggest changes, and each one waits in the text for you to keep or reject. The Proofing Pass is a deliberate pass you start, not a layer running as you type, and it changes only the corrections you accept.
Can I publish work I wrote here?
Yes. Robin's words stay in chat unless you keep a suggestion in Edit Mode, and every one of those is your call. You own 100% of what you write. If you keep suggested changes, check your publisher's or contest's policy on machine-suggested edits.
Are my drafts used to train AI models?
No. Your drafts are never used to train models unless you opt in (see Privacy). Text reaches AI services only when you trigger a feature, and only the context that feature needs.
How is this different from tools that analyse a manuscript you upload?
Those return a report on a file. Write in a Click reads the book where you already write it, with your Story Hub and voice profile as live context, and can re-read it as the book changes. There is nothing to export, upload or re-brief.
Why use AI at all if it does not write your book?
Because writing was never the part an author most needed help with. Knowing how a chapter lands before anyone reads it, seeing the shape of a book too long to hold in your head, being told your middle sags — those were impossible or expensive before, and they are what the AI here is for.
