How It Works
From AI generation to human approval in four simple steps
AI Generates Content
Your automation creates responses, posts, emails, or any content that needs human oversight before going out.
Send to Human-in-the-Loop
Workflow sends the AI-generated content for approval with any context, guidelines, or source materials the reviewer needs.
Human Reviews and Refines
Reviewer gets a secure link, sees the content with full context, and can approve, reject, or refine using AI assistance—all from any device.
Approved Content Continues
Once approved, the content flows back to your automation and continues to its destination. Rejected items can trigger alternative actions.

Frequently Asked Questions
How does batch processing work?
Batch processing allows you to group multiple approval tasks together and review them in sequence. When you approve or reject a task, you're automatically shown the next pending task in the batch. This creates a seamless review flow where you can handle dozens of approvals efficiently without navigating back to a list view. You can configure batch grouping based on time windows or specific criteria in your workflow.
