Anthropic launches Claude Tag, an always-on AI teammate that lives in your Slack channels

TL;DR

Anthropic launched Claude Tag, an always-on Slack AI that follows conversations, learns context, and proactively jumps in to flag updates and tasks.

Anthropic is launching Claude Tag in research preview, an “always-on Claude” that lives inside Slack and acts as a persistent AI teammate. The feature lets users tag @Claude to get insights in conversations and assign tasks. It is available to Claude Enterprise and Claude Team customers starting today.

Claude Tag is an evolution of Anthropic’s existing Slack integrations, which already let users direct-message Claude or tag it in channels for on-demand help. Claude Code in Slack can also route coding tasks from channel mentions to full coding sessions on the web, posting updates back into the thread. But Claude Tag adds a layer of persistent context and memory that the previous tools could not maintain.

“As Claude follows along with its channel, it learns ever more about the work,” Anthropic said in a statement. Claude can also automatically gather facts from elsewhere in the organisation if granted permission to read other channels. The result is an AI that accumulates institutional knowledge over time rather than starting from scratch with every interaction.

Everyone in a given Slack channel can access a single Claude identity, meaning anyone can see what Claude has been working on and pick up the conversation from where the last person left off. System administrators specify which tools, information, and channels each Claude identity can access, and each identity stays scoped to whichever channels the admins define. A Claude set up for legal work cannot seed memories into the engineering channel, for example.

When assigned a task, Claude Tag breaks it into stages and works through them using whichever tools it has access to, responding in a Slack thread with what it has created. But the more notable feature is an ambient mode that proactively jumps into conversations to keep teams updated, flag relevant information from across the organisation, and follow up on threads or tasks that have been forgotten.

The ambient mode is the feature that separates Claude Tag from a conventional chatbot. Rather than waiting to be asked, Claude monitors the channels it has been assigned to and intervenes when it judges that a team would benefit from a reminder, a summary, or a piece of context pulled from another part of the company. Anthropic says this makes it feel like “working with a real colleague, one that can produce work in public view, with far greater context and understanding than before”

Organisational context is increasingly the battleground for enterprise AI. Microsoft has been building Work IQ, an intelligence layer expressed through Copilot that draws on Microsoft Graph to understand roles, collaboration patterns, and organisational structure. Startups like Viktor have raised tens of millions to put AI coworkers directly inside Slack and Teams.

Glean, which recently surpassed $300 million in annual recurring revenue at a $7 billion valuation, is building a permissions-aware knowledge graph that sits between the model and enterprise data.

Claude Tag is Anthropic’s answer to the same problem, but its approach is narrower and arguably more disciplined. Rather than building a horizontal intelligence layer across every enterprise application, it plants the AI inside the one surface where most knowledge work already happens: the team chat. The bet is that persistent presence in Slack, combined with cross-channel memory and admin-controlled scoping, is enough to accumulate the institutional context that makes an AI agent useful.

The privacy implications are substantial. An always-on AI that follows along with workplace conversations and autonomously decides when to intervene will face scrutiny from both employees and compliance teams. Anthropic’s admin-scoping controls are the structural answer to that concern, but the real test will come when enterprise customers deploy it at scale and discover how workers respond to an AI that is always listening.

Anthropic says it is working to bring Claude Tag to other platforms in the coming weeks. For now, Slack is the only surface, which limits the feature’s reach but also constrains its complexity, a deliberate trade-off for a research preview.
