Decision Data for Better Processes

Capture the why.
Improve what’s next.

Every annotation, review, and expert decision becomes structured data. Sentious captures the reasoning behind each judgment and turns it into actionable insights.

Decision-data workflow: an annotation, reviewer feedback, the structured decision record, and the process improvements it drives, looping back to improve the next annotation

Quality Built In

Every annotation
has a path to trust.

Sentious continuously evaluates confidence, agreement, provenance, sensor quality, and reviewer feedback to determine what can pass, what needs review, and what requires expert judgment.

Routing flow: a confirmed Grasp annotation passes through Quality Signals to auto-pass, review and correct, or expert review and adjudicate — all ending in verified ground truth
