An AI agent review interface is the human-facing layer of an AI finance system that exposes, at document or transaction level, the full reasoning behind every AI decision, extracted fields, matched sources, applied rules, confidence scores, and flagged anomalies, so that a finance professional can validate, correct, or escalate each item with complete information.
It is the operational counterpart of the black box problem. When an AI system processes 500 invoices and returns "312 validated, 23 flagged", the question is: why were those 23 flagged, what exactly was extracted from each document, and on what basis was each validation decision made? The review interface answers all three questions at the unit level.
The interface is what makes human-in-the-loop control real, not theoretical. Without a usable review layer, exceptions surface as abstract alerts, "anomaly detected on invoice #847", without the context needed to resolve them quickly. With a structured review interface, the finance team sees the invoice, the extracted fields, the rule that triggered the flag, the reference value it was compared against, and the recommended action, all in one view. Resolution time drops from 15 minutes of investigation to 30 seconds of review.
Phacet's Vue Détail is its implementation of the review interface. For every document or transaction processed by a Phacet agent, the Vue Détail shows extracted fields with their source evidence highlighted, the AI's reasoning in natural language, the confidence score on each field, and the alert detail if an exception was raised. The finance team validates, corrects, or escalates with a single click. Every action is logged with timestamp and user, building the audit trail in real time.
As Alban Cacace, COO of Jinchan, put it: "On voit exactement ce qui est fait. Rien n'est caché." That visibility is the structural reason Phacet's outputs are defensible in front of an auditor, not just internally trusted. For DAFs who need to show their work, the review interface is the product feature that makes AI finance control credible.
