Turing Test

Can you spot the AI? Over 8 rounds you read two answers to the same question, one written by a person and one by AI, and pick the AI.

Features

• 8 rounds with a shuffled question order, ending with a bonus round about ELIZA.
• After each pick, the answer is revealed with a clue on how to tell them apart.
• A final score screen with confetti.
• Keyboard shortcuts for picking and moving to the next round.

Stack

React 19 · TypeScript · Vite · Tailwind CSS v4 · shadcn/ui · Framer Motion · Vitest. No backend.

Development

Requires Node 22.18+ (.nvmrc pins 22).

npm install
npm run dev

Scripts

Command	What it does
npm run dev	Dev server at http://localhost:5173
npm run build	Typecheck and production build into dist/
npm run typecheck	TypeScript check (tsc -b)
npm run preview	Serve the built dist/ locally
npm run lint	ESLint
npm test	Unit tests (Vitest): shuffle and question data
npm run check	Typecheck, lint and tests
npm run deploy	Checks, builds and uploads to the VPS
npm run deploy:dry	Same, but only previews the upload

Deployment

The site is static: npm run build writes dist/, which is synced to a VPS where Caddy serves it directly (no restart needed).

1. One-time setup: copy .env.example to .env.prod.local (git-ignored) and fill in DEPLOY_HOST, DEPLOY_PORT and DEPLOY_DIR. You also need SSH key access to the server.
2. Deploy:

   npm run deploy:dry   # preview what would change
   npm run deploy       # checks, build, upload

How it works

• Questions live in src/data/turing.json. Each one has a prompt, human answers, AI answers and a clue. The type: "eliza" question is always the last round.
• Each round picks one human and one AI answer and shuffles their order (src/utils/shuffle.ts).
• The game is a small reducer state machine: start → playing → revealed → … → finished.
• UI. shadcn/ui components live in src/components/ui/ (vendored, added with npx shadcn add, not linted). The theme tokens in src/index.css give them the indigo look. The answer cards' flip is custom; src/lib/styles.ts holds the large classroom button style.
