IAmA scientist and entrepreneur named Luis von Ahn. I’m the CEO/co-founder of Duolingo, a totally free way to learn languages. I won’t rest until people stop paying for crappy language learning software. I also developed CAPTCHA and reCAPTCHA, those squiggly characters all over the web -- sorry! AMA

IAmA scientist and startup CEO named Luis von Ahn. I developed CAPTCHA and reCAPTCHA, those squiggly characters you see all over the web (sorry!). I'm now working on Duolingo, a new way to learn languages while helping to translate the Web. AMA.

I am Luis von Ahn, the creator of reCAPTCHA, those squiggly characters all over the web, and the co-founder and CEO of DUOLINGO! Duolingo has become the most popular way to learn languages online, for free, and has overtaken expensive and gimmicky alternatives like Rosetta Stone. AMA!
