Claude in Slack: the @Claude teammate, explained.
Your team's AI use has a silent tax: it all happens in private tabs. Someone solves a problem with Claude, the insight dies in their chat history, and the next person re-solves it next week. The org pays for AI per person and captures none of it as a team.
Claude Tag (launched June 23, 2026) is Anthropic's answer: Claude as a persistent teammate inside Slack — added to the channels you choose, connected to your tools, data and codebases, where anyone can tag @Claude to delegate work.
What makes it different from a bot
- Multiplayer by design. One Claude per channel, its work visible to everyone, and anyone can pick up a thread it's working in. The output stops being trapped in one person's tab — that's the entire point.
- Memory built on channel history (plus sources you authorize): it arrives knowing the context of the discussion it's joining.
- Ambient mode. Proactive, not just reactive — it can watch for things and alert the channel.
- Async tasks. Delegate something and it can schedule itself and work "over hours or days," reporting back in the thread.
It runs on Opus 4.8. Anthropic's own datapoint on how far this goes: 65% of their product team's code flows through their internal Claude Tag.
Who can get it
As of this writing: beta, Team and Enterprise plans only. It replaces the older "Claude in Slack" app (existing workspaces get a 30-day admin opt-in migration). Nothing on Free, Pro or Max yet — though Anthropic says it intends to extend @Claude beyond Slack.
Setup, in the order that works: pair your Slack workspace, connect tools, set the org's monthly spend limits, and pilot in a private channel before letting it loose. Launch credits exist for eligible orgs.
Channel memory, personal memory
Claude Tag remembers the channel. Your own working memory — the decisions, clients and context that live in your claude.ai chats and Claude Code sessions — is a different layer, and it's the one that follows you when you change teams, tools or machines. That personal, portable layer is what we built Klyr for. Team memory in Slack; your memory with you.
