Anthropic gives administrators a 30-day window to migrate from the old Claude in Slack app to Claude Tag. An admin starts the move for the workspace.
Claude Tag vs Claude in Slack
Claude Tag vs the old Slack app.
In June 2026 Anthropic replaced Claude in Slack with Claude Tag. It is a bigger change than a rename - here is what actually moved.
The short version.
The original Claude in Slack app was, in practice, the Claude assistant reachable from Slack: you summoned it, it answered, and the context lived with whoever asked. Claude Tag reframes that into a shared teammate - one Claude per channel that learns from the conversation, works on its own initiative, and carries tasks across hours and tools. If you ran the old app, the change is worth understanding before you migrate.
What actually moved.
The shifts that matter, side by side.
| Claude in Slack (old) | Claude Tag (new) | |
|---|---|---|
| Shape | An assistant you summon per person. | One shared Claude per channel, multiplayer. |
| Initiative | Answers when prompted. | Ambient mode speaks up on its own. |
| Memory | Little durable channel context. | Learns the channel over time, scoped by admins. |
| Work | Mostly a turn of question and answer. | Plans steps, acts across tools, schedules its own tasks. |
| Control | Per-user usage. | Per-channel tool/data scopes, token caps, audit log. |
| Availability | Broadly available. | Beta, Claude Team and Enterprise only. |
Why the change is bigger.
The headline difference is initiative. The old app was a better way to reach Claude from where you already worked; it still waited for you. Claude Tag's ambient mode flips that - it follows the channels it is in, raises what you might have missed, and chases stalled threads without being asked.
The second difference is that it is multiplayer. Instead of each person having a private thread with Claude, a channel has one Claude that everyone shares and can build on, with a memory scoped to the channels an admin defines. That is what lets it act like a teammate rather than a personal tool.
The trade is that Claude Tag is, for now, gated. The old app was broadly reachable; Claude Tag is in beta for Claude Team and Enterprise customers and runs on the Opus 4.8 model, with admin controls and token caps that fit a managed rollout more than a quick personal install.
How to migrate.
If you were running Claude in Slack, moving across is a short, admin-led job.
Re-scope per channel
Because Claude Tag is channel-shared with its own memory and tool access, set which tools, data and memories it can touch in each channel rather than carrying over a per-user setup.
Decide where ambient mode belongs
Turn proactive, ambient behaviour on only in the channels that want it, and set token caps before you do - autonomous work runs without you watching.
A lighter way to start.
Claude Tag is the right upgrade if your team is on a Claude plan and committed to Slack. If what you actually wanted was a teammate that is not tied to one chat app or one vendor's plan, Beagle covers the same ground from a different starting point.
Not Slack-only
Beagle is native to Slack and Microsoft Teams, so the half of your org on Teams is not left out.
Not beta, not gated
Generally available today, free to start on one seat, with no Team or Enterprise plan to buy first and nothing to migrate.
Same teammate instincts
Lives in the channel, learns your people and decisions, acts across ~2,700 tools - and waits for your nod before anything goes out.
Common questions.
Is Claude Tag the same as Claude in Slack?
No. Claude Tag replaced the older Claude in Slack app in June 2026. The old app was an assistant you summoned per person; Claude Tag is one shared Claude per channel that learns the conversation, works on its own initiative in ambient mode, and carries multi-step tasks across tools.
What happened to the old Claude in Slack app?
Anthropic is retiring it in favour of Claude Tag and gives administrators a 30-day window to migrate their setup across.
Is Claude Tag available to everyone the old app was?
Not yet. Where the old app was broadly reachable, Claude Tag launched in beta for Claude Team and Enterprise customers only.
What if I do not want to be tied to Slack?
Beagle is a teammate in both Slack and Microsoft Teams, generally available and free to start, with the same instincts - it reads your channels, learns your team, and acts across your tools with your approval.
