## Summary

Every founder I know has the same problem with email support. In the early days, you handle it yourself. You are fast, you are personal, and you actually know the product. Then you get busier. Response times slip. Users start to notice. You think about hiring someone, but the volume does not justify it yet. So you buy a helpdesk tool, set up some canned responses, and tell yourself you will get to the backlog this weekend. You never get to the backlog.

## Overview

The premise is simple. Most support emails for a software product fall into a small number of categories. Installation questions. Feature questions. Configuration issues. Occasional bugs. The answers to most of them live in the documentation, the README, or a known issue list. A well-instructed AI agent can probably handle 70 to 80 percent of those without human involvement. The other 20 percent, the ones that need judgment, need access to the codebase, or need a business decision, get forwarded to the human. The agent does not need to be perfect. It needs to be fast, accurate on the common cases, and honest about its limits. That is a very achievable bar. What I built is not a chatbot widget. There is no interface for users. Users just send an email. The agent reads it, decides what to do, and either replies or escalates. The entire loop is invisible to the sender.
