Anthropic has been moving fast in June 2026. Real fast. But the story that dropped this week cuts through all the noise: Claude is now inside your Slack.
Anthropic just launched **Claude Tag** — a new feature that lets teams tag @Claude directly inside Slack channels to delegate tasks, build context over time, and work asynchronously. It's live today in beta for Claude Enterprise and Team customers.
And this isn't just a chatbot bolted onto a chat app. It's something meaningfully different.
Here's what actually changes for your team:
you grant Claude access to selected channels and connect it to your tools, data, and even codebases — then anyone in the channel can tag @Claude and hand off a task while they move on to other things.
Claude doesn't sit there waiting to answer a question.
It builds context by remembering relevant information from the channels it's in, and can plan out tasks to complete in the future.
That's a fundamentally different relationship than what most AI tools offer today.
The multiplayer angle is the sleeper feature here.
There's one Claude that interacts with everyone in a given channel — meaning anyone can see what it's working on and pick up the conversation from where the last person left off.
That's collaborative AI, not just personal AI.
How big is this internally at Anthropic?
Tagging @Claude is now one of the main ways work gets done at Anthropic itself — 65% of the product team's code is created by their internal version of Claude Tag.
That's not a marketing stat. That's a company eating its own cooking.
For teams worried about runaway access,
Claude Tag was designed with tight controls — administrators specify which tools and information Claude has access to, per channel, effectively creating separate Claude identities with scoped memories, so a sales-focused Claude won't hand engineering data to the dev team.
This launch lands amid a bigger month for Anthropic.
The company released Claude Fable 5 on June 9 — a new tier above Opus and its most capable generally available model, scoring more than 10% higher than Claude Opus 4.8 on some benchmarks.
Less than a week later, however, Anthropic announced it received a US government export-control directive requiring it to suspend access to both Fable 5 and the restricted Claude Mythos 5, while all other Claude models remain unaffected.
That's a genuinely wild subplot — Anthropic's most powerful public model, pulled within days of launch by government order.
Claude Tag, though? That one's live, available, and quietly signals where AI tools are heading: not as a thing you open in a tab, but as a teammate already in the room.
