## What it is
OpenTag is an open-source, self-hosted knowledge-work AI agent for Slack and Microsoft Teams, built as the starter application for the Channels SDK using AG-UI and a Python LangGraph agent. It ships with connected tools, generative UI (native Slack charts, approval-gated Linear issues, cited research briefs), and production-shaped Railway and AWS deployment options.

## Use cases
- deploy an AI assistant bot in Slack and Microsoft Teams
- triage on-call alerts from a chat channel
- turn a spreadsheet into a Slack chart and a Linear issue with approval gate
- fork a starter app to build my own chat agent with tools
- self-host an AI agent connected to Slack and Teams
- run a LangGraph agent inside a messaging platform

## When to choose
- you want a deployable, production-shaped AI agent in Slack or Teams rather than building from scratch
- you want generative UI like native Slack charts and approval gates in threads
- you want a self-hosted, MIT-licensed agent you can fully customize
- you use AG-UI/LangGraph and want a reference integration with the Channels SDK

## When to avoid
- you need a chat channel other than Slack or Microsoft Teams
- you want a fully managed SaaS bot with no infrastructure to run
- you need a general-purpose agent framework rather than a starter application
- your stack is not Node.js/TypeScript with a Python agent runtime
