What’s New

Build with Harvey (Magic Builder) introduces a conversational workflow-building experience directly into Workflow Builder.

You can now describe the workflow you want in natural language, and Harvey generates the corresponding block-based workflow structure. After creating a workflow, you can continue refining and updating it through an ongoing conversation with Harvey instead of manually editing blocks one by one.

With Build with Harvey (Magic Builder), you can:

  • Create workflow agents by describing the process you want to automate
  • Refine workflows conversationally after the initial workflow is created
  • Reduce manual block-by-block configuration and testing
  • Make more targeted workflow updates compared to the existing Improve feature
  • Continue using the existing block-based Workflow Builder experience alongside conversational editing

This helps you:

  • Build workflows faster
  • Prototype workflow ideas more easily
  • Reduce time spent maintaining workflows
  • Iterate on workflows as requirements evolve
  • Lower the learning curve for creating custom workflow agents
