Why Centaur Labs?

Scale data annotation exponentially

Stop annotating data slowly with in-house teams or outsourcing to teams whose quality you can’t control.

Access the Centaur Labs network of thousands of medical doctors, professionals, researchers and students for skilled annotation

Embed data annotation seamlessly into your data pipeline with end to end API integration

View labeler-level insights to give you confidence in the Centaur Labs network

Take control of annotation quality

You define quality. We rigorously measure and manage it.

Measure labeler performance. Only include opinions from labelers whose quality score meets your expectations

Incentivize labeler performance with small batch, mobile-first competitions. Labelers are only paid for performance and give 100% of their effort on every case

Generate multiple reads on each case, and even more on ambiguous cases

Master your dataset

Proactively understand the nuances of your dataset, so your data works with you, not against you.

Access meaningful statistical information about your dataset

Leverage case-level insights to inform model development e.g. precision-recall curves, label distribution, labeler agreement

Identify edge cases and challenges with data quality based on flagged cases and labeler comments
