Human review lets you add a verification step to your pipeline where a person reviews and optionally corrects AI-extracted data before it proceeds.
When to use human review
- High-stakes documents: financial, legal, or compliance documents where accuracy is critical
- Low-confidence extractions: only review documents where the AI is uncertain
- Training period: review all documents initially, then switch to low-confidence mode as you refine your schema
Adding a review step
- Open your pipeline in the editor
- Add a Review action node after your extract action
- Connect: Extract Action → Review Action → (next step)
- Configure the review node
Configuration
How the review workflow works
- The run reaches the review action and pauses
- A review task appears in the review queue
- A reviewer claims and reviews the extracted data
- On approve: the run resumes with the (possibly corrected) data
- On reject: the run is marked as failed
Example pipeline with review
A common pattern is to extract data, review it, then send it to a callback:
Upload Trigger → Extract Action → Review Action → Callback Output
This ensures a human validates every extraction before results are delivered.
Tips
Start with trigger mode set to Always when first deploying a pipeline. Once you’re confident in the extraction quality, switch to Low confidence to reduce manual review volume.
- Write clear, specific review instructions to guide reviewers
- Use the low-confidence threshold to balance accuracy and review workload
- Review tasks are visible to all users with review permissions in your organization
