    Summary

    AI copilots and AI agents represent different levels of AI autonomy. Copilots assist professionals with individual tasks under human direction, while agents autonomously plan, reason, and execute complex multi-step workflows. Both are valuable but serve different purposes.

    When to Use Each

    Use a copilot when professionals need real-time assistance with specific tasks while maintaining full control. Use an agent when the workflow is well-defined, repeatable, and benefits from end-to-end automation. In most professional services contexts today, copilots are the practical choice.

    Frequently Asked Questions

    Should my firm use AI copilots or AI agents?

    Most professional services firms should start with AI copilots for immediate productivity gains, then evaluate agentic AI for well-defined, repeatable workflows once the technology matures.
