The data-centric sibling of your favorite programming IDE. Enables you to program your labeled data within hours instead of months.

Here’s what our users say

The example of kern shows how closely research and entrepreneurship are intertwined at HPI. The system, which emerged from a research project, helps data scientists to implement precise AI models significantly faster and to integrate business departments into the development process.

refinery enables us to create high-quality training data within hours instead of weeks. You can tell that it is designed by and for Data Scientists, and we can use it for several use cases. I wouldn't want to miss it.
Joan Reyero
Crowd.dev, CTO
With refinery we were able to drastically simplify and organize a process of automated, standardized content classification, while simultaneously creating an implicit labeling documentation to rely on. The rich and versatile Python SDK allowed for a seamless integration with our pre-existing architecture.
