Margin notes for your labeling team

Label text and images with one steady console.

OpenClassifier gives teams a single workspace where reviewers, models, and policy checks stay in sync. It feels like sharing a well-loved notebook — everyone sees the same cues and the next move is obvious.

Built for clarity first. Each view reads like margin notes from a teammate while the APIs stay production-ready.
