We provide access to unlimited data for training accurate and robust AIs.

About Us

AI learns about our world through data, and its performance depends on the diversity, complexity, and quantity of the data. But collecting such data through manual collection and annotation is time-consuming, error-prone and challenging to scale up, and has often become a bottleneck in AI development. At 4Data, we develop data generation technology to supercharge the AI development of your application. Our technology uses mathematics to accurately create infinite, diverse and complex data with annotations at large scale for training accurate and robust AI models.

This video showcases our technology. In one click, we generate a large variations of two popular Hong Kong food, egg tart and pineapple bun, with complex geometry details and annotations, which can be used to train AI models.
