JotterDown
A writing app for novelists. The v1 is live at jotterdown.app. The v2 rebuild — type naturally, every character and timeline event is tracked behind the scenes, and a single fact change shows you exactly which pages need to update before you commit — is in flight right now (manuscript-first UI in dev).

01 · Problem
Novelists need a writing surface that respects long-form structure — characters with psychology, timelines that branch, prose you can interrogate — without becoming yet another AI-everything writing toy.
02 · Approach
- 01
TipTap as the editor primitive, customized for chapter / scene / character contexts.
- 02
Supabase + Stripe for auth and subscriptions; Claude as an opt-in analytical layer, never a generator-by-default.
- 03
Worked the prose-analysis surface in tight 1–3 minute iteration cycles to keep felt latency invisible.
03 · Outcome
Live at jotterdown.app. Currently being used to write a novel — the dogfooding loop drives the roadmap.
