Crew turns one assistant into a bench of specialists.

Each persona is a full role definition, not a one-line system prompt: domain knowledge, the decision frameworks that role actually uses, the questions it asks first, and the metrics it cares about. Activate the CFO and you get unit economics and runway thinking. Activate the UX researcher and you get research design and a warning about your sample size.

Thirteen personas ship with the server: CEO, CFO, CTO, CMO, product manager, analyst, data scientist, legal advisor, UX researcher, sales engineer, support, creative and developer relations. All are available on the free plan.

Beyond single roles there are two group modes. Council puts several personas on the same question and returns their disagreement, which is more useful than a blended answer. Ensemble assembles a standing team — the executive board, for instance — that you call as one unit.

16 MCP tools cover activating and switching personas, running the group modes, listing and running workflows that chain roles into a sequence, and saving your own personas and workflows to your account so they follow you across machines.

It runs inside your existing assistant subscription. Crew supplies the roles and the orchestration; the model doing the thinking is the one you already pay for, so there are no extra token costs from us.
