Letterbook

Letterbook is an AI-native customer support agent built for founders and fast-growing teams. It connects directly to your inbox, database (MongoDB, Supabase), and Stripe account to automatically resolve support tickets using your own data and playbooks. Unlike traditional helpdesks, Letterbook can get started in 15 minutes and continuously improves with every ticket resolved.

• AI Ticket Resolution — Connect your inbox and let the AI automatically draft and send replies based on your defined scenarios and live data.
• Database & Stripe Integration — Give the AI read access to MongoDB, Supabase, or Stripe so it can look up orders, subscriptions, and account details in real time.
• Scenario Playbooks — Define instructions for each type of customer request (refunds, login issues, bug reports) and the AI follows your playbook precisely.
• Review & Send Workflow — Each ticket gets an AI-drafted reply with cited sources; review, give feedback, and send to continuously improve response quality.
• Unified Inbox — Manage all support channels from a single contact center built for speed with shortcuts and a modern UI.
• Smart Knowledge Base — Support scenarios auto-update as tickets are resolved, keeping your documentation current without manual effort.
• Analytics Dashboard — Track resolution time, automation rate, and customer satisfaction to measure support performance.
• Fast Onboarding — Import your tickets and knowledge base to launch your contact center in minutes, not weeks.
