 **AI-powered demand-letter drafting for law firms** — draft, collaborate on, and format legal demand letters with AI-assisted argument building, a reusable clause library, and court-rules-aware formatting.

Documents and clauses are bundled fixture data; AI suggestions are live (OpenRouter free-tier models via the API's rate-limited endpoint — the first call after idle may take ~30–60s while the free-tier server wakes).

+## Live demo
+
+The hosted demo (**demo mode**) serves bundled fixture data — no database and no real accounts — while AI suggestions call the live API (free-tier models, rate-limited and capped). Sign in with any email and password to explore the full UI.
 
 ## Local setup
 
 ```bash
 git clone https://github.com/franciszver/lexforge.git
 cd lexforge
 npm install
-cp amplify_outputs.example.json amplify_outputs.json   # placeholder backend config
+VITE_DEMO_MODE=1 npm run dev   # demo mode: fixture data, no backend required
+```
+
+To run against a local API server instead:
+
+```bash
+cd server
+cp .env.example .env   # fill in DATABASE_URL, JWT_SECRET, OPENROUTER_API_KEY
+npm install
+npx prisma generate
 npm run dev
 ```
 
-The placeholder config is enough to build and explore the UI. For a live backend (auth, data, AI), deploy an Amplify sandbox — `npx ampx sandbox` — which regenerates `amplify_outputs.json` with real resource IDs. Details in [docs/SETUP.md](docs/SETUP.md).
+```bash
+VITE_API_URL=http://localhost:3001 npm run dev
+```
+
+Details in [docs/SETUP.md](docs/SETUP.md).
 
 ```bash
-npx vitest run   # 450+ tests
-npm run build    # production build

+cd server && npm test   # server: 218 tests
