Shinder Tarot

A tarot learning platform: a 78-card reference, 30+ tutorial articles, and a drawing tool with four spread engines. The learning content is written in Traditional Chinese; the drawing tool is fully translated, so you can use it end to end in English.

What the drawing tool does

Four spread engines — a daily card locked to one draw per day; three-card spreads with three selectable position sets; two five-card themed spreads; and the Celtic Cross, which walks you through the ten cards in reading order rather than card order.
Shuffling runs in your browser, on crypto.getRandomValues with rejection sampling so the deck order isn't skewed by a modulo. No sign-in, and no draw is ever uploaded.
A reading journal — save any draw with a one-line note. Entries live in your browser; subscribers sync the most recent 1,000 across devices.
Reversals are off by default. That is a teaching decision, not an oversight: upright meanings first, reversals once those are solid.

What's behind it

All 78 Rider-Waite-Smith cards, each with imagery, symbolism, and historical notes.
A structured course of 30+ articles, per-article quizzes, and reading-progress tracking.
An AI reading guide that only ever asks you questions — it will not hand you a verdict.
A companion React Native app that shares the same backend, content pipeline, and card data.

How it's built

One Cloudflare Worker serves everything: Hono for routing and server-rendered HTML, D1 for accounts and learning data, KV for rate limiting, Workers AI for the reading guide, and better-auth for Google and Apple sign-in. No client-side framework — the interactive parts are plain modules against a server-rendered page. Tests run inside workerd, so they execute in the same runtime as production. The app and the website live in one pnpm monorepo and share a single source of truth for card data and article content.

A note on language

Card names, spread positions, and the whole drawing flow are in English. The card meanings and the tutorial articles are in Traditional Chinese and are not translated — translating 78 full card entries and 30+ long-form articles would be a different project. Links that lead into Chinese pages are marked (中文) so you always know before you click.
