Marcel — autonomous AI for business

Marcel is an autonomous AI agent for practical business work. Give it an objective in plain language; it plans the steps, chooses models and tools, executes workflows, checks results, and asks for clarification or approval when needed.

Marcel is designed for business owners, executives, managers, and teams. Typical work includes research, reporting, competitive analysis, drafting, data gathering, and operational coordination.

Permissions and human approval

Autonomous execution does not remove human accountability. Sensitive actions such as spending money, sending external communications, or modifying critical records should follow the organization's approval boundaries.
