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, tho...
Hi Reddit! It’s me again, Luis von Ahn. I’m the co-founder/CEO of Duolingo, which aims to provide the best way to learn languages to everybody for free. I think that education makes people’s lives better, and shouldn’t be limited only to those who have the money to learn.
Today I’m especially excited because we just launched the Duolingo Android app. You can download it from Google Play here. If offers full language courses that are 100% free, with no ads, hidden charges, or BS “in-app purchases.”
You may be interested to know that there’s an awesome Duolingo subreddit.
I'm also a computer science professor at Carnegie Mellon, and I'm from Guatemala. I developed CAPTCHA and reCAPTCHA (acquired by Google).
I'll start at 2pm ET, so ask away!
UPDATE [4:45pm]: Still hard at work answering your questions. Getting some help from my top advisor, Coco: http://imgur.com/fGNi1hy
UPDATE [7:30pm]: Taking a little break. I'll come back online later tonight to answer a few more questions :)
