Just completed a new type of language learning website - read popular stories scaled to different reading levels

As a language learner and software developer, I bootstrapped my project superlang.com over the past year working on the side. There is a mobile friendly web app now, and iOS/Android apps coming in a few months.

A year ago I discovered the concept of "comprehensible input" as a way to help me learn German. Even if it's not a silver bullet, it sounded pretty great. Rather than drilling vocab or looking at grammar charts, I could "just read" and acquire the language. I picked up some fairy tales in German, and stories like Alice in Wonderland.

Unfortunately, I couldn't really read them. I had to stop every sentence to look up words and try and decipher sentence constructions. Then I turned to some purpose built simple stories for German beginners. But there was a different problem... these were not really stories with any real plot. I could only read so many "Hans goes to the market" type stories before losing interest.

My idea was to try to get the best of both worlds somehow. What if I could take a real story, say Alice in Wonderland (or even War and Peace), and dial the difficulty down to my level without losing the plotline. That way, beginners can start right away with something basically comprehensible. Then, you could also re-read the same story at increasing difficulty levels as you gain confidence. As a cherry on top, more illustrations would help with comprehension so each page could have a picture.

Is it revolutionary? Maybe, maybe not. I am building off a well established idea of "graded readers" which are simplified stories meant for learning languages. And there are somewhat similar ideas out there now that AI is good at simplifying text, but none that really take this idea where it needs to be with many preloaded stories, multiple difficulty levels, high quality human verified text, and all the bells and whistles.

I spent a year building Superlang and it is ready to put out there. Some quick notes:

• There are 3 languages so far, intended for native English speakers: German, French, and Spanish
• There are 3 difficulty levels you can set on each story: beginner (roughly A1-A2), intermediate (roughly A2-B1), and advanced (the same level as the original story, but typically B2+)
• There is premium version as producing the content was somewhat expensive. You can still do a lot of reading on the free version. I have done no marketing yet, except for this post :)
• The implementation is a combination of AI, and human proofreading and reviewing. In particular, the simplification of stories is very heavily AI driven. The illustrations for each page are AI as well. For translation, as many of you may be aware new LLM models are typically better than Google translate, but still far from perfect. I am very much a proponent of keeping real people in the loop, and so I have real people proofread the translations. That's why there are only about 700 pages of content so far and not tens of thousands.

Let me know what you think, and if you find it helpful!

Alice in Wonderland - beginner level German

Romeo and Juliet - beginner level Spanish
