Introduction

engineer9 is an AI teammate that lives in your team’s Slack, with the instincts of a senior staff engineer.

@mention it with any engineering question and it responds with depth and precision, checking its memory of your team, systems, and past incidents before answering.

Think of engineer9 as a teammate that builds and keeps your team’s context. It knows when to step in and when to stay quiet, and it asks before doing anything with real consequences. It can automate routine work too, but that’s a capability it has rather than its purpose.

What it does

Section titled “What it does”
  • Answers technical questions with context about your specific stack and team
  • Manages incidents and stores resolutions as playbooks for next time
  • Tracks team knowledge: who owns what, system dependencies, policies
  • Integrates with Linear: create, update, and assign issues from Slack
  • Runs scheduled tasks: EOD summaries, health checks, periodic reminders

How it works

Section titled “How it works”

When you ask engineer9 something, it checks its memory of your team: roster, playbooks, and past decisions. It surfaces the relevant context, acts on it, and saves anything new it learns back to memory. It also acts on its own when it can help, answering an unanswered question it knows or flagging a stale incident.

For the full picture of memory, reflection, ownership detection, and how it decides when to step in, see How it works.
