Do you use a captcha to keep out bots? hCaptcha is a drop-in replacement for reCAPTCHA that earns websites money and helps companies get their data labeled.
Sign UpAd networks see your visitors as their product. For hCaptcha the product is the work they provide. We don't care who your users are, only how likely they are to be malicious. We support initiatives like Privacy Pass, and work hard to balance privacy and security.
hCaptcha is publisher-focused. We work to give you real data and let you decide how to use it. Accuracy is in your interest and ours. Other captchas are provided by
advertising companies. This means every bot they block is likely to reduce their revenue.
Sophisticated machine learning models are used by hCaptcha for determining humanity. This lets us require less annoying tasks from your users and take less of their time in doing so, while still producing valuable data for our labeling customers.

hCaptcha provides simple, easy, and reliable bot detection while being trivial for humans to solve.
Did you realize every time you "click on the car" you are helping to train a single
company's machine learning systems for free?
hCaptcha turns this model around. When you use hCaptcha, companies bid on the work your users do as they prove their humanity. You get the rewards.
Want to give back to your favorite charity? hCaptcha lets you support the charities of your choice with the earnings you gain from using it.
Users on your site will be able to see your contribution to charity through discreet branding on the hCaptcha interface.
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, Figure Eight, etc. is both slow and expensive.
hCaptcha allows websites to make money serving this demand while blocking bots and other forms of abuse.
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.
