DuoBook: Generate bilingual stories to learn any language

My best friend and I had been trying to learn Dutch for a while. About a month ago, we picked up some Donald Duck books in Dutch, thinking they'd be fun and simple to start with. But soon enough, we found ourselves constantly switching between the book and our phones, struggling to follow the story—definitely not the immersive experience we had hoped for...

That’s when I remembered those books with one language on one page and the translation on the opposite page. Inspired by that concept, I thought, why not use AI to create something similar, but even more interactive?

So, we built DuoBook.

Here's how it works:

1) Start writing your story in your language.

2) Select the language you want to learn.

3) AI helps complete the story, side-by-side with your native language.

It’s still early days, and it might not be perfect, but it's genuinely helping us—and we hope it helps you too!
