What it does
A Slack app for talking to ChatGPT in channels, for drafting and thinking out loud where the team already is. The author leads the README by pointing at OpenAI's own Slack integration and suggesting you try that first — worth taking seriously before deploying this. If you do use it at work, deploy to your own infrastructure rather than the author's personally-hosted demo, as they recommend, and check the data path against your company's rules. MIT.
Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.
