Learning a new language is hard...

Hi. I'm Marko, the guy who spends way too much time talking to computers.

I too have watched too many "White Guy Speaks Perfect Chinese, Shocking Everyone" videos. Here is the issue: Language learning is hard.

I lived in Korea for 10 years, and all I can say is "hello" and "f*** you" in Korean. I mean, I can order food, but only if the menu has pictures.

In order to learn a language, you need to practice speaking. The issue is that involves talking to people. And people are scary.

So, why not just talk to a computer?

ChatGPT is great, but it limits your talking time, and every conversation ends with 'I can't help you with that'.

Not to mention, my memory allows me to remember the content of a conversation for about 5 minutes. After that, we're back to square one.

That's when I remembered I'm a programmer.

"I have GPT, I have an ANKI, *smashes them together* Dialogo!"

And there you go. A language learning app that doesn't suck and actually delivers on the promise of fluency.

The Team

Passionate about immersive learning. Loves Korea and wants to learn Korean (he lived there for 10 years but still can't speak it). Spent 3 months working on this project instead of just learning Korean. Very good at programming though.
