What is reCAPTCHA?
reCAPTCHA is a free service that protects your website from spam and abuse. reCAPTCHA uses an advanced risk analysis engine and adaptive challenges to keep automated software from engaging in abusive activities on your site. It does this while letting your valid users pass through with ease.

The reCAPTCHA advantage

reCAPTCHA protects and defends
reCAPTCHA is built for security. Armed with state of the art technology, reCAPTCHA is always at the forefront of spam and abuse fighting trends so it can provide you an unparalleled view into abusive traffic on your site.

Easy for People. Hard for Bots
Purposefully designed. And actively aware. reCAPTCHA knows when to be easy on people and hard on bots.

Help everyone, everywhere - One CAPTCHA at a time.
Hundreds of millions of CAPTCHAs are solved by people every day. reCAPTCHA makes positive use of this human effort by channeling the time spent solving CAPTCHAs into annotating images and building machine learning datasets. This in turn helps improve maps and solve hard AI problems.
