YasmineAdd a new coworker to your team in 60 seconds
Yasmine is an AI coworker that lives in your Slack. Each channel becomes a teammate with its own memory, its tools and integrations — running on your own Claude subscription, fully isolated.
@Yasmine the login test is failing on main — fix it and open a PR.
Found it — the token expiry check used < instead of <=. Fixed, tests green.

Per-channel coworkers
One persistent Claude session per Slack channel — its own memory, tools, and integrations.
Hard isolation
Each customer runs in their own microVM with their own Claude subscription. Nothing crosses tenants.
Any MCP tool
Wire GitHub, databases, analytics, ticketing — per channel, with approval gates on writes.
You're already using AI. You're also still doing the work.
Most AI tools generate text. Yasmine executes — in Slack, where your team already is.
| Task | Other AI tools | Yasmine |
|---|---|---|
| Fix a failing test | Tells you what might be wrong | Reads the repo, fixes it, opens a PR |
| Wire up an integration | Generates a snippet to paste | Connects the tool and runs it for you |
| Triage an issue | Suggests where to look | Investigates across repos and replies in the thread |
| Ship a small change | Writes code in your editor | Edits, tests, and PRs from a Slack mention |

Frequently asked questions
Do I need my own Claude subscription?
Yes. Yasmine runs on your own Claude account, connected inside your isolated environment. We never resell tokens, and your subscription is never used for another customer.
How is my code and data isolated?
Each customer runs in its own Firecracker microVM (AWS Fargate) with a separate kernel, filesystem, secret store, and IAM role. A cross-tenant leak is structurally impossible.
Will it make changes without asking?
No. Reads run automatically; writes and destructive actions pause for a human approval in the Slack thread. You set the policy per channel.
What tools can it use?
Any MCP server — GitHub, databases, analytics, ticketing, and more — wired per channel with allow/deny lists. It reads code, runs tests, and opens PRs.
How long does setup take?
Minutes. Sign up, add the bot to Slack, connect your Claude account, and mention it in a channel. No new app for your team to learn.
Is it open source?
Yes — Yasmine is open source and self-hostable. The cloud version adds managed hosting, isolation, and billing.
