Everytime you fill in CAPTCHA you’re helping to digitalize old books and documents. Using CAPTCHA abt 250 books are added to a digital database everyday

Its called RECAPTCHA! The creator of CAPTCHA (Luis von Ahn) realised a lot of time was being wasted with CAPTCHA (worldwide we spend about 500,000 hours doing CAPTCHA every day)

So he wanted to put it to good use

The reason why CAPTCHA uses wonky letters is because computers can’t read them, but we can!

But when trying to automatically digitalise old books and documents this becomes a hindrance because computers often cant read the faded old letters. So the digitalising is done by humans (very costly and time consuming)

Anyway Ahn found out about these a integraded into captcha creating RECAPTCHA.

Everyday about 150 (sorry i meant 150 not 250) old books get digitalized this way. They are currently using it to digitalize the whole archive of The New York Times (since 1851)

So we’re all kinda building a digital library of alexandria this way by using captcha, noice


reCAPTCHA Founded 2007. Overview reCAPTCHA is a free CAPTCHA service
that helps to digitize books, newspapers and old time radio shows.
reCAPTCHA improves the process of digitizing books by sending words that
cannot be read by computers to the Web in the form of CAPTCHAs for
humans to decipher.

In case any of you thought this was BS

I always love seeing reCAPTCHA being used.

That’s what my dad told me too.

So when we fill out those wonky letters, we are basically helping the computer read weird handwriting.
