A daily writing game. Each day you get a story type and three keywords. Write a two-sentence story using them. Your score reflects how well your response aligns with the keywords.

Think Wordle, but for writing.

How it works

1. A deterministic prompt is generated each day (seeded PRNG, so everyone gets the same prompt).
2. You write two sentences (150 characters each, max).
3. Your submission is scored using embedding-based semantic alignment against the keyword subspace.
4. Scores are displayed as a multiplier above random chance (e.g. "10.0x").

Stack

• SvelteKit 5 + Tailwind v4
• Supabase (auth, database, edge functions)
• Vercel (hosting)
• OpenRouter (embeddings via Qwen3-Embedding-8B)

Development

npm install
npm run dev

Building

npm run build

Supabase

Edge functions live in supabase/functions/. The submit function handles scoring server-side so the embedding math stays out of the client.

Supabase secrets required:

• OPENROUTER_API_KEY
• SUPABASE_URL (set automatically)
• SUPABASE_SERVICE_ROLE_KEY (set automatically)
