Notes from the demo run
AI-generatedWe created an account on neubook.app and drove the Write Studio end-to-end: described a book idea, picked the How-to guide format, answered the two questions your model wrote for that specific idea, approved an 11-chapter plan, and watched the book start writing itself with a generated cover. The sequencing is the best part — you never ask for anything you have not already earned the right to ask for.
Highlights
- The interview is generated from the idea, not a fixed formWe typed a book about browser testing for solo founders, and the questions that came back asked about a specific testing mistake we had made and a contrarian opinion on end-to-end testing. Each carried a 'Why it helps' line. That is the moment the product stops feeling like a template filler.
- The plan is editable before a single word is written11 chapters, each annotated with its shape ('opens with confession · ends on image · form: case study'), with reorder, cut and add-a-chapter controls and an explicit 'Nothing is written until you confirm'. Giving the user the veto before the expensive step is the right call.
- Writing is resumable and honest about time'Writing chapter 3 of 11. Usually about 1.3 min per chapter, 3 at a time, so roughly 4 min to go. You can close this tab.' A real estimate plus permission to leave beats a spinner every time.
Friction points
- The format tiles and the shelf cards are ambiguous to anything scriptedYour book-type tile and the sidebar card for an existing book both read as 'How-to guide' to an automated reader, so our first pass silently reopened an old book instead of choosing a format. A data-testid (or putting the format label after the title on shelf cards) removes the ambiguity for scripts and screen readers alike.
- Signup sits inside the studio with no standalone routeAccount creation is an inline panel at /write/studio?account — there is no /signup or /register to link to. That makes the signup step hard to link from a tweet, an email, or an ad, and it is a one-line redirect to add.
