How a 3-Day Hackathon Gave Non-Engineers Access to the Codebase at Remote.com

At Remote, the people who need codebase knowledge most — support agents, PMs, sales — are the ones least equipped to read code. We built Sherlock App in a 3-day hackathon: a Phoenix LiveView app powered by OpenCode that lets anyone ask questions about the codebase in plain English and get accurate, source-linked answers in seconds.

In this lightning talk, I'll cover how we went from idea to company-wide deployment: the architecture (GenServer-based SSE streaming, Ash Framework for instant Okta SSO, OpenCode as the AI engine), how MCP servers let Sherlock pull context from Notion and Linear alongside code, and what happened when non-engineers started getting answers without filing tickets or interrupting developers.
