+# InterviewForge
+
+> Generate tailored interview questions in seconds.
+
+InterviewForge takes a job description and forges a complete, role-specific interview
+question set — technical, behavioral (STAR), and follow-up questions — in under a second.
+No AI API, no cloud, no data leaves your machine.
+
+## Features
+
+- 🎯 **Tailored to the role** — detects skills in the job description (Python, AWS, Docker,
+  SQL, React, sales, PM, leadership…) and serves matching technical questions
+- 🧠 **STAR behavioral set** — 8 proven behavioral questions, 3 sampled per run
+- 🔁 **Follow-up/clarifying questions** — interview the interviewer with precise follow-ups
+- ₿ **Pay with Bitcoin** — one-time $9 premium via BTCPay Server
+- 🕵️ **Zero backend** — pure Python stdlib + Flask, no external APIs
+
+## Endpoints
+
+| Route | Auth | Description |
+|-------|------|-------------|
+| `/` | — | Landing page |
+| `/health` | — | Health check (JSON) |
+| `/pricing` | — | Free vs Premium |
+| `/register` | — | Create account |
+| `/login` | — | Login |
+| `/dashboard` | ✅ | Core tool: paste JD, forge questions |
+| `/process` | ✅ | POST `input_data` → question set |
+| `/checkout` → `/checkout/create` | ✅ | BTCPay invoice (one-time $9) |
+| `/webhook/btcpay` | — | BTCPay webhook (settles payments) |
+| `/payment/success`, `/payment/cancel` | ✅ | Checkout transitions |
+| `/about`, `/sitemap.xml` | — | SEO |
+
+## Tech Stack
+
+Flask · SQLite (WAL) · BTCPay Server (Greenfield API) · nginx reverse proxy ·
+systemd `interviewforge.service` · Python 3.9-compatible (stdlib only)
+
+## Deployment
+
+- **Host**: Proxmox LXC container (Debian 12, host: `proxmox` on 10.30.20.85)
+- **App dir**: `/opt/interviewforge`
+- **Service**: `systemctl restart interviewforge`
+- **nginx**: port 80 → `127.0.0.1:5000`
+
+## Paying
+
+Premium is a **one-time** $9 payment via Bitcoin. The BTCPay webhook
+(`InvoiceSettled`) flips the user to premium — no recurring charges.
