hCaptcha: Accessible Captcha Service

An AI-powered captcha service to deter bots while letting valid users interact with ease, offering a user-friendly alternative to reCAPTCHA.

What is HCaptcha?

hCaptcha is an accessible captcha and bot detection service created by Intuition Machines in 2017 as an alternative to Google's reCAPTCHA. It helps website owners prevent spam and abuse from bots and malicious actors while aiming to provide a better user experience for legitimate human visitors.

Unlike reCAPTCHA which relies solely on visual challenges that can be difficult for some users, hCaptcha offers the option of various challenge types including image labeling, text transcription, and intuitive visual challenges. These are powered by hCaptcha's Human Verification Engine that utilizes advanced AI techniques to distinguish humans from bots. The system learns from user interactions to improve accuracy over time.

In addition to bot detection, hCaptcha is customizable allowing website owners to tailor the service to suit their needs. It aims to be more privacy-focused than reCAPTCHA by anonymizing user data and avoiding tracking. hCaptcha also offers an accessibility statement letting visually impaired users request audio challenges. There is even an option for enterprises to keep all data processing on-premise for compliance or data residency requirements.

By combining AI with a range of challenge types that play to human strengths, hCaptcha provides an innovative user-friendly captcha and bot detection service for websites. The company claims over 100,000 websites use hCaptcha including Chatroulette, Chegg, and Shutterstock.
