Anthropic Launches Claude Tag: A Persistent AI Teammate for Slack
Anthropic
Anthropic launched Claude Tag in beta on June 23, 2026, for Claude Enterprise and Team customers. It adds Claude as a persistent, multiplayer Slack team member that users can @-mention to delegate tasks. Claude learns from channel history over time, can work asynchronously, and — when ambient mode is enabled — proactively flags relevant information without being prompted. The feature runs on Claude Opus 4.8 and replaces the existing Claude for Slack app. Anthropic reports that an internal version already generates 65% of its product team's code.
Why it matters
Claude Tag is Anthropic's most direct move into the enterprise collaboration software market, turning Claude from a chatbot into an always-on autonomous agent embedded in the workflow layer where teams actually operate. The multiplayer design — one shared Claude per Slack channel — is a new interaction paradigm that enables collective delegation rather than individual prompting.
