Case study
Grimoire Keeper — a modular digital grimoire for people who keep their own practice
Codex, Almanac, reading help, and quiet counsel — one archive for practitioners whose thinking was scattered across notebooks, screenshots, and half-abandoned note apps.

01
Research
Books tell you what a card means. They can't tell you what it meant to you last October. The gap between reference material and lived practice is where every practitioner I spoke to lost their notes.
The observed pattern was consistent: correspondences in one app, seasonal notes in another, reading logs on paper, and no way to ask any of it a question later.
Structured, private, and shaped around your own vocabulary — not someone else's.
02
UX decisions
Four modules, each usable on its own: Codex (personal definitions), Almanac (cycles and seasons), reading help (mid-reading lookup), Counsel (reflective questions).
Nothing prescribes a system. The vocabulary is yours; the software's job is to hold it and hand it back when you need it.
Three tiers so the free version is genuinely useful, not a demo: Seeker (free), Keeper's Circle ($4.99/moon), Archivist ($9.99/moon).
03
Iteration
Built from day one, not planned first and built second. The early version worked, mostly, and then the real work started — a continuous stretch of breaking things, fixing them, and revising until it looked and felt the way it was supposed to.
No clean milestones to point to, just steady iteration until it was right. It's live and downloadable today. Not yet in the app stores — that's next.
04
Implementation
TypeScript, React, PWA, Stripe. Live at grimoirekeeper.com and installable to the home screen today.
05
Lessons learned
Modularity earned its keep. People adopted one module first — usually the Codex — and only added the others once the first one felt like theirs.
The free tier is the product. Anything less than 'genuinely useful on its own' would have made the paid tiers feel like a paywall instead of a thank-you.
