Duolingo turns two today!

We launched the Duolingo website two years ago at 10:08am EST. It was supposed to be at 10:00am -- lots of people were waiting -- but Tony, Vicki and Severin were still making last minute changes. And then Ryan wanted to change the background color of the whole site. But in the end it worked out, and we were only 8 minutes late :) We couldn't believe we had a whopping 17,000 users that first day.

A lot has happened since then:

Thanks for all of your support! We are spreading free language education together.

June 19, 2014



30 million users give a hoot about this. I really like the staff picture, very cute :)


I can only recognize Luis from this image, and I think that the tall blond women with the blue dress in the bottom row is Myra, but I'm not sure, can someone indetify them all?

I think Mukkapazza is the second one (left to right) on the bottom row.

Alt text.


I wonder who can juggle like that. It's so cool O.O

  • 2385

Seems to be David Klionsky!



Which one's the graphic designer? Because he/she is amazing! Love the picture!


I think severin's next to luis.


Myra is the one in the mustard colored shirt, next to the juggler. I've had it confirmed. ^^
I think the one in the blue dress could be Gina, Gina's tall'ish... but not that tall, so I think Gina is next to Luis and Severin, being a press officer and all :P


Kristinemc is the one in the lavender, bottom row, I think. :)

Second from left (top): Severin Hacker

Second from right (top): Tyler Murphy?

Third from left (bottom): Caitlin Lownes?


Wait, I can't see the image though! T_T

EDIT: I can see it now. I also found it on Twitter xD
EDIT2: Thank you! My browser really needed that. Turns out it had a big update it wanted to make because I never shut my browser lol.


Better restart your browser! :)


When in doubt, shut it out. ;)


That's what I thought! It looks a lot like her profile picture.


The others are harder, as I'm not familiar with most of them yet. Time to study. :)

你怎么那么清楚? lol


Thank you soo much. Do you know who is working in the duolingo store?


congratulations duolingo


Happy birthday Duo! Congratulations to the team!


olimo!!!!! Happy Duoversary to you too :) Hope all is well!


How's that little one doing????


That's a lot of milestones right there!
Congratulations with the duoversary and thanks so much for giving me the opportunity to keep refreshing, complementing and improving my language knowledge! (:


Happy Duoversary to Luis and the team! I only joined a couple of weeks ago and I am already hooked! It has been a great tool and I hope it continues to be as I progress.

I am using it to learn a few languages so that I can communicate with my patients, especially in Spanish and French as I hope to join Médecins Sans Frontières at some point after I graduate and hopefully Duolingo will be a big part of that, communication is such an important tool when someone is ill or in distress so thanks Duolingo!


Gracias a ustedes por todo lo que nos han regalado, simplemente ha sido una idea genial. Espero que muy pronto vea nuevas características para PC.

Happy birthday, Duolingo! I'll continue to contribute my knowledge of Chinese here! Love you!



I'd like to improve my chinese ! Do you know when it could be launched ? (From english or french)

  • 2385

No one knows yet. We'll start working on the reverse course after our English course for Chinese speakers enters Phase 3. Check the incubator often and stay tuned!



Thank you for the answer ! I'll check it ;)


I'm also looking forward to the traditional Chinese version. =)


¡Felicitaciones! I love this site, and can't wait to see all that you have in store for language education in the future!

I have learned more in nearly two months here than in months of formal teaching, and it's all for free. Thank you for this great idea, Luis. Here's to many more!


Muchas gracias ;) duolingo


Happy Duoversary!!!, This was a great idea to help us to learn languages, I only can say Thanks Duo!!


I would have sworn that I used Duolingo for four years.


Wow. I can't believe how much I've missed :( I've been here since late April 2014 (at the earliest, on another account) and I really wish I was able to see all of this. 4 million the first year. 30 million the second year. That's basically 7 and 1/2 times the amount from the previous year! Surpasses Rosetta Stone (totally not worth it, heard it just threw vocabulary words at you) in Google searches. Won "iPhone app of the Year" during its second year (an impressive feat). Wins "Best Educational Startup at the 2014 Crunchies (same year). And with a team of only 32 employees! All in 2 years... just amazing. Duolingo team, you have really worked so hard to get all this recognition. And 30 million! Think of it as 30 thousand thousand people who signed up for free language education! Thanks a bunch, Duolingo team, for making free language education around the world more accessible to everyone. Happy #duoversary!


A proud day for Duolingo team and a proud day for All Duolingoers! It was nice to see the timeline.


felix dies natalis tibi sit, duolingo ! ad multos annos ! - the only two year old I know who speaks so many languages so well


Thank you once again for everything!


Bene! The best, most helpful language learning site and app I have come across!


สุขสันต์วันเกิดนะ Duolingo!! :) ขอบคุณมากด้วย :D


Muchas gracias y felicidades. Thank you a lot and congratulations Muito obrigados e parabéns


Congratulation, Luis! Your work has made a huge difference in the lives of so many people :)


Happy birthday Duo, it’s been wonderful learning from you! As long as your teaching, I don't think I'll ever stop learning. May you have, many, many more birthdays!


Congratulations. Thank you so much for all you guys do. you have no idea how much Duolingo has changed my life and continues to do so. Vous m'inspirez


Happy Birthday Duolingo! What an amazing journey you have been on in the last two years. It's amazing to see how the site has grown and expanded. Congratulations to the whole team :) I really can't wait to see how Duolingo improves and expands even more over the next few years!


Feliĉan naskiĝtagon. ;-)


You all are awesome! Thank you very, very much!


Danke schön, Duolingo! I have been here since 3rd March 2013, and learning German, Spanish, Portuguese, Dutch and will soon be improving my Irish (and hopefully learning Maltese soon!). So vielen dank' für alles, Duolingo - but just one thing - why isn't 'StrapsOption joins Duolingo' marked on the timeline for 3rd March 2013? †

† Ich scherze!

Congratulations on 2 years! I still send people to your TEDxCMU talk because it does such a great job of framing the questions that motivate my work as well, and it was a pleasure to see that (and your Show & Tell presentations) live. It's great to see where it's come since then, and there's still a lot of room left to grow!


"It's great to see where it's come since then"

I would absolutely second that! It will be good to know about your work too!


Gefeliciteerd! (congratulations!) I just joined Duolingo and I love it. Improving my German and learning Spanish. Duolingo is just awesome.


Happy birthday Duo! =)


I consider myself a duolingo original, but looking back at all of this old stuff, I suddenly feel extremely insignificant xD.


Congratulations to the entire team! Keep doing a great job. We are all "hoooting" for you! :D


Teşekkürler Luis! - Happy birthday, Duolingo!


Happy Anniversary! :D


Parabéns pelo excelente trabalho que vocês tem feito, a DUOLINGO é sem dúvida atualmente a melhor empresa para aprendizado de língua estrangeira. Continue assim!


2 years now? Impossible! That was too quick :)

Je dois vous remercier pour votre site web! Je ne suis pas parfait mais avec l'aide du duolingo et sa communauté j'ai appris assez français pour faire le bac! J'espere toujour pour l'opportunité de parler le français. Quand on ira en france cet ete je parlerai tout le temps!

He mejorado mi espanol y ahora puedo charlar y hacer bromas. Hice un intercambio con espana y gracias a ti, yo pude disfrutar de la vida, sabiendo que pude hablar bien el Espanol. Encontré la gente que fue asombrado de mi abilidad en el idioma. Siempre estuve hablando el Espanol (y mis discursos estuvieron llenos de errors pero) cada persona me pudo entender!

Asi, hace falta declarar que duolingo es simplemente el mejor sitio de internet para aprender las lenguas y como las lenguas te dan tanto confianza, experiencia, inteligencia y sentido en la vida, aqui estamos aprendiendo por la vida

Ta orm deir go bhfuil is fearr broduil me!

Finally a chance to learn what should be my native tongue! Go raibh mile maith agaibh agus is athas orm mar chonaic me "an gcursa gaeilge" sa pictuir ón goradáin (The pic from the incubator!)

So now thanks to duolingo the world has many more aspiring polyglots, aiming to learn for work, holidays, willingness to preserve cultures, improve their minds, making them want to get out more and live life through language. Still full of errors but who wants perfection? Now I feel I still have loads more to go, a reason to keep going and its good!!!

Gracias, danke schoun, merci, go raibh mile, grazie, obrigado, ačiū,labai and thanks loads. Gratias tibi ago.

And one big happy birthday




I can read 2 languages English and Spanish. Though there is no Arabic... So I will write it: عيد ميلاد سعيد !


Yes Vsetko najlepsie :) Is my language Slovakian :)


I joined December 2013. I <3 Duolingo!


I have tried many websites for learning a foreign language before and I could say with no doubt that Duolingo is different and better than all other, a real treasure!!! Muchas gracias Duolingo :)


Happy Birthday! I wish I got you all a present.


Happy birthday Duolingo! Congratulations !!


feliz aniversario!


¡Muchas Felicidades! Gracias a Duolingo tengo la oportunidad de aprender inglés y alemán, esperando ansiosamente aprender japonés y coreano también en este asombroso sitio.


Happy Birthday Lingo ! You are the best ! :) Hooray !:)


Hapy B'day Duo................................ :)

Great job Duo Team! I've been learning Portuguese and I think you have been a great help!


Happy Birthday and thank you so much. You are all wonderful and I appreciate your efforts. It has been wonderful to use this fabulous site. I can see the improvements in the 6 months that I have been using it. Thanks again so much.


The prelaunch duo is really freaking me out.


It should be called "Polylingo", since almost everybody I see here is learning 3+ languages!


time really flies. Impossible almost 2 years have passed since I signed up in december 2012. :) Duolingo really improved constantly ever since.


Duo is turning 8. And still going! 300+million users is something to be proud of. Congrats, Duo!

The timeline is not completely correct, the 3rd and 9th of october 2013 should be switched. For the rest, I really enjoy spending time on duolingo despite the critics and eagerness of a lot of people on the forum for making improvements too slowly. Just keep the steady peace (Y)

Happy Duovsary!

I've been using Duolingo for a little more than a half year. I regret not having know Duolingo earlier, so I try to introduce Duolingo to more people, including my mum. It's great to see Duolingo make the world a better place where people could communicate a lot easier.

Please keep the good job and I'm looking forward to the next two, five, ten years with Duolingo!


Parabéns Duolingo, e muito obrigado por tudo.

Happy Birthday Duolingo!!!


Wow! I only got on yesterday but I've learned more German than a month on a different app. And it's fun, too!


i feel like i learn it faster too.


Can I coin the term Duoversity? It just hit me, reading this story in the WSJ while waiting for family at the airport in Des Moines, about this Venezuelan entrepreneur whom created Open English, and is making a lot of money, and planning to launch an online university. Once proved to the world that you can teach and learn any language "for free", why not doing the same with formal courses in different fields? We can reach the sky some times. The university of the future is Duoversity! http://online.wsj.com/articles/online-school-has-100-000-students-one-subject-1403050947


@jorma1998b I love when people creatively link words to Duolingo. This is the first time I've heard of "Duoversity". It now joins the list I'm keeping in my head:

EDIT: I'm sad to be the bearer of such news to you: First time "Duoversity" showed up on Duolingo, coined by user Atanaa.) https://www.duolingo.com/comment/2051755

  • Duolingoer--A Duolingo user
  • Duolingoter--A Duolingo user who gives away a lot of lingots (??)
  • Duoredditor--A Duolingo user who is also involved in the Duolingo reddit (I'm not sure if this is any user or just the D.R. moderators.)
  • Duoversary--Duolingo's 2nd birthday (though, I wonder if people will use it to mark the passing of each year regardless)
  • Duowikian--A Duolingo user who is an editor at the Duolingo wiki. and now Duoversity! :D


Only two? 30 million users is alot for only two years


Happy Birthday Duolingo!


Muito obrigado Duolingo! feliz aniversário


Thank you so much DuoLingo team for being so amazing and bringing this website into existence! May Duo be around for many, many years to come!


Happy Birthday Duolingo!


Barely a week into learning Spanish and I am seduced, addicted and thrilled to be learning so much so quickly! Happy Birthday and many cheers for an incredible service!!


Thank-you for all your help... thanks to you, 30 million people are learning many new languages!! This really helped me get far in Spanish and Italian this year!


Duolingo thanks a lot. You guys are helping me out to learn Spanish and soon Dutch. You guys rock!!!

Greetings all the way from Brazil. ;)


wooooowo Duolingo you can do more and more, go on.


"End of 2014: Duolingo launches Windows Phone App" I hope to see it!


thank duolingo


Guys, you're awesome! Congrats!


축하드립니다! 저도 언젠가 이렇게 가치있는 일에 열정을 불태워 보고 싶습니다. 많은 생각을 하게 하는 프로그램을 만들어 주셔서 감사드려요.


Duolingo is amazing! I can't thank you enough for a chance to learn Irish and French for free!


Top marks to the producing team at Duolingo!! Well done!!! Jayant krishnan


Duolingo changes very fast! It's impossible :)


Exciting ! Great ! Thanks for all of you.


Very interesting! You should update this more often


Duolingo was born the day before my birthday! Pretty cool! Let's celebrate together.lol



J'adore Duolingo. I've always said learning should be fun, and it's free too!


Wow. Duolingo has been through a lot.


Pretty soon you guys and girls will be turning 3! Wow! :) Just passing your toddler years and as they say "the toddler years are a time of great cognitive, emotional and social development" (wiki). In that sense, you are a perfect toddler any mom would be so proud to have! :) It would be nice if you could update the previous timeline, I am sure a lot has happened in these past 12 months! :) I strongly believe that "knowledge is the only treasure that increases on sharing". Thank you so much for being an online treasure for almost three years!


wo xihuan peng you!


(Sorry for of topic comment, but this is important, but I can't get Duolingo's attention on these for months now)

This is official post https://forum.duolingo.com/comment/10727793 to get votes for English for Georgian speakers course.

700+ votes from that post are gone, https://forum.duolingo.com/comment/25398737 and Doulingo hasn't fixed this.

Learn a language in just 5 minutes a day. For free.
