Helping everyone, everywhere, one CAPTCHA at a time

CAPTCHAs play an important role in keeping the internet spam-free and making everyone’s experience a little bit better.

reCAPTCHA also makes positive use of the human effort spent in solving CAPTCHAs by using the solutions to digitize text, annotate images, and build machine-learning datasets. This in turn helps preserve books, improve maps, and solve hard AI problems.
