Transparent, flexible pricing
Pay per labeled object or per annotation hour — whichever fits your project. Every engagement starts with a free pilot, and there are no long-term contract requirements.
| Engagement model | Best for | How it works |
|---|---|---|
| Per labeled object | Well-defined, high-volume tasks (boxes, polygons, entities) | Fixed unit price agreed after the pilot; you pay only for accepted labels. |
| Per annotation hour | Complex, exploratory or evolving guidelines (RLHF, evaluation, red teaming) | Dedicated annotators billed hourly with full productivity reporting. |
| Dedicated team | Ongoing programs needing domain knowledge retention | A stable, trained team scales up or down with monthly flexibility. |
