How CAPTCHAs and Duolingo are Changing the Web, with Your Help

This is awesome. I love Ted Talks! This one is from 2011 but I just watched it for the first time today.

Have you ever used Duolingo to learn a language? If you haven’t it is great and I definitely recommend that you check it out. You can access it from a computer or download the app. Oh and it is completely free!


reCAPTCHA Example

Have you ever filled out a CAPTCHA or a reCAPTCHA? If you ever filled out a form online, you probably have; it’s that little code/picture/puzzle that helps protect websites from spam by verifying that you are, in fact, human.


Did you know that you are actually contributing something amazing every single time you use Duolingo or fill out a reCAPTCHA?

Every time you complete a CAPTCHA, you help digitize text, annotate images, and build machine learning datasets which in turn helps preserve books, improve maps, and solve AI (Artificial Intelligence) problems (Google reCAPTCHA).

And when you use Duolingo to learn a language you are also helping translate the web into every major language.



Pretty awesome right? I just had to share this video!

Thank you Luis von Ahn for presenting this Ted Talk on Massive-scale online collaboration and thank you Netflix for helping me find it today!
