SetFlow.ai — Your AI Appointment Setter That Never Sleeps

Stop chasing leads. Let AI book your meetings on autopilot.

SetFlow.ai is a fully functional, open-source AI-powered appointment setter that captures leads, handles objections, answers pricing questions, and books discovery calls — all without human intervention. Built with Node.js, Express, SQLite, and the Anthropic Claude API.

This is not a demo. This is production-ready.

What It Does

• AI Chat Agent — A smart conversational assistant that qualifies leads, answers questions about your services, handles objections, and guides visitors to book a call
• Lead Capture & Tracking — Automatically captures visitor info, tracks status (unqualified → qualified → booked), and stores full chat history
• Auto-Booking Detection — AI recognizes when a user agrees to book and triggers the booking flow automatically
• Webhook Integration — Connects with Cal.com / Calendly to confirm bookings and match them to leads
• Dashboard — Real-time stats, recent bookings, lead management with search & filters
• Configurable AI Persona — Edit the system prompt, company name, and calendar link from the UI

How the AI Books Meetings

1. Visitor enters name & email → lead is created as unqualified
2. AI chats naturally — answers questions, handles objections
3. When visitor shows interest (mentions "schedule", "book", "meeting"), lead becomes qualified
4. When AI determines user is ready, it includes [ACTION_BOOK_MEETING] in its response → lead becomes booked
5. Cal.com webhook confirms the actual booking and matches it back to the lead
