About hCaptcha

hCaptcha is designed to solve the most labor intensive problem in machine learning: labeling massive amounts of data in a timely, affordable, and reliable way.

More data generally produces better results in training machine learning models. The recent success of deep models has led to increasingly large datasets, almost always with some human review. However, creating large human-reviewed datasets via Mechanical Turk, Crowdflower, etc. is both slow and expensive.

hCaptcha allows websites to make money serving this demand while blocking bots and other forms of abuse.

AI companies get data labeled by website owners who use hCaptcha

Powered by HUMAN Protocol

The hCaptcha marketplace is powered by the HUMAN Protocol, an open decentralized protocol for human review that runs on the Ethereum blockchain.

Websites earn Human Tokens (HMT) whenever users use the hCaptcha widget on their site, and machine learning companies pay Human Tokens to get their data labeled.
