Core Features
Everything your business needs to never miss a lead

Claude-powered AI agents that handle SMS conversations, capture customer info, and know when to loop in a human.

💬

Twilio SMS Integration

Dedicated phone numbers per client. Inbound SMS hits a webhook, Claude processes the message, and the response is sent back via Twilio REST API. Full E2E flow.

🤖

Claude AI Conversation Engine

Claude Haiku 4.5 powers every response. Configurable personas, greeting messages, and a 5-iteration tool loop with prompt injection defense built in.

📊

Analytics Dashboard

Summary cards for total SMS, conversations, resolved rate, and 24h activity. Daily volume charts, conversation status breakdown, and agent performance tables. Pure CSS charts.

✅

Form Validation

Client-side per-field validation with inline errors across all forms: registration, login, agent config, and settings. E.164 phone format enforcement for escalation numbers.

💰

Stripe Billing

Three-tier subscription model with Stripe Checkout and Customer Portal. SMS quota enforcement in the conversation engine automatically rejects messages when limits are exceeded.

👥

Multi-Tenant Auth

NextAuth.js v4 with email/password and JWT sessions. Organization-scoped data isolation, super admin role for platform management, and middleware-protected routes.

Response
Twilio sendSMS()
// Conversation engine flow (src/lib/engine/conversation.ts) // 1. Twilio webhook receives inbound SMS // 2. Validate Twilio signature (replay attack prevention) // 3. Look up phone number → agent → organization // 4. Check SMS quota (rejects if monthly limit exceeded) // 5. Find or create conversation for this sender // 6. New conversation? Send agent greeting (skip Claude call) // 7. Existing conversation? Build prompt with persona + history // 8. Claude processes with tool_use (max 5 iterations) // 9. Tools: capture_lead, check_hours, escalate, send_info, resolve // 10. Send response via Twilio REST API

AI Capabilities
Claude tool-use powers every conversation

Five built-in tools let the AI agent take real actions on behalf of your business.

capture_lead
Save customer name, email, phone, and notes. Automatically captures lead info from natural conversation without awkward forms.
check_business_hours
Check if the business is currently open. Returns schedule so the agent can inform customers of operating hours.
escalate_to_human
Forward the conversation to the business owner's phone via SMS. Triggered when the AI can't handle a request or the customer asks for a person.
send_business_info
Share business address, hours, services, and other details. Pulls from the organization's configured profile data.
mark_resolved
Close the conversation when the customer's question has been fully answered. Updates status for analytics tracking.
// Agent persona configuration (per-agent, fully customizable) { "name": "Alex", "persona": "You are Alex, a friendly receptionist for Acme Plumbing...", "greeting": "Hi! Thanks for reaching out to Acme Plumbing. How can I help?" } // New conversations with a greeting skip the Claude API call entirely // Tool loop capped at 5 iterations to prevent runaway costs // Prompt injection defense built into system prompt
