## 🚀 Mission

The AI Clients organization owns the client-side surfaces where customers experience GitLab Duo. We bring GitLab's AI capabilities directly into the tools customers already use and we provide the shared client SDK that powers those experiences across platforms.

## 💬 Where to find us

### Slack

We follow the [GitLab Slack channel prefix conventions](/handbook/communication/#slack): `s_` for the cross-team stage/organization channel, `f_` for functional-team channels (engineering + PM + UX together), and `g_` for engineering-only group discussion. Underscores separate distinct things; hyphens join words within a single thing.

| Scope | Channel | Purpose |

| ----- | ------- | ------- |

| Organization | `#s_ai-clients` | Cross-team AI Clients discussion for all disciplines (eng, PM, UX, stakeholders) |

| Duo Client SDK | `#f_language_server` | Duo Client SDK / Language Server functional team |

| Duo CLI | `#f_duo-cli` | Duo CLI functional team |

| VS Code | `#f_vscode_extension` | VS Code extension functional team |

| JetBrains | `#f_jetbrains_plugin` | JetBrains plugin functional team |

Engineering-only group channels (`#g_duo_chat`, `#g_editor-extensions`) remain for now while membership and stakeholders migrate to the `f_`/`s_` channels above.

### Product categories

The AI Clients teams own product categories that fall under the [AI-powered stage](/handbook/product/categories/#ai-powered-stage) of the [DevOps lifecycle](/handbook/product/categories/#devops-stages).
