Why I built this

I wanted my team to use Claude Code without everyone needing their own setup. Screen sharing works but only one person can type. With claude-threads, colleagues watch Claude work in Slack and can jump in to help, approve actions, or ask questions. All from chat.

After the first minimal version, I built claude-threads using claude-threads. Colleagues watched, asked questions, and caught bugs in real time. It turns out that multiple people guiding the same AI session actually works.

The bot runs on your machine. You control what projects Claude can access.
