What is Letterbook?

Letterbook is an AI-native customer support platform designed to streamline helpdesk operations for modern, fast-scaling teams. Built to replace traditional tools like Zendesk, it integrates directly with your existing tech stack, including databases like PostgreSQL and payment processors like Stripe. The core capability lies in its AI agent that does not just draft responses but also performs complex actions like issuing refunds or downgrading subscriptions based on real-time data. It supports omnichannel communication across email, Discord, and mobile apps, ensuring a unified support experience. By automating triage and ticket resolution, Letterbook allows support teams to focus on high-priority issues while maintaining human-level accuracy. It is particularly well-suited for SaaS startups and AI-forward companies looking to launch a helpdesk in minutes rather than weeks.
