Human-in-the-Loop
Add review and approval steps to AI-generated content and automated workflows

What is Human-in-the-Loop?
Human-in-the-Loop is an approval workflow extension that adds a human review step to your automations. It’s specifically designed for AI-powered workflows where you want to verify, approve, or reject automated outputs before they’re sent or published.
Think of it as a safety checkpoint in your automation - AI generates the content, a human reviews it, and only approved items continue through the workflow.
When to Use Human-in-the-Loop
Real-world scenarios where the extension is used:
Approve AI-generated responses to Google Business reviews before posting publicly - Ensure brand voice and tone are appropriate for each customer interaction
Final sign-off on AI-qualified sales leads before routing to your team - Verify lead quality and fit before sales reps invest time
Review AI-written customer support responses before sending - Catch potential misunderstandings or tone issues that could damage customer relationships
Approve AI-generated social media posts before publishing - Maintain brand consistency and avoid PR risks from automated content
Key Features

Metadata support - In addition to reviewing main content, pass additional metadata and make it visible to review and can be used to control the next steps in the workflow (Eg: pass customer email, ticket id).
