Immersion

Language learning with literature, June 21, 2026

For the past couple of weeks, I've been working on a language learning tool that lets you get immersed in a text in the language you're learning, while giving you all the tools you may need to understand it, and test your understanding with writing and speaking. This is Immersion - a free, locally-saved language learning powerhouse that works with nearly any language you can think of, and gives you all the tools you need to really understand literature in that language.

It supports short stories, full books, PDFs, and even YouTube videos. It lets you use AI to support understanding, but without becoming a crutch. You can practice with flashcards, have the text read to you, and write essays to practice using the language you are learning. I'm excited about Immersion, because I believe we have been handicapped in our language learning for too long. Some of the greatest minds of history learned languages this way, by reading a book in their target language, and practicing by writing and speaking. Additionally, you will be learning with whatever content you actually want to read, not just a mass-produced lesson that teaches you how to say "Giraffes are tall" and moves on to the next random sentence.



Immersion has allowed me to read The "Interior Castle" by St. Teresa of Avila in the original Spanish and get help along the way to really understand what's going on in the text. I've started reading 1 John in the original Greek, and the letter from St. Ignatius to the Smyrneans. I have read Latin texts, German short stories, and watched Hungarian videos with the aid of a transcript. All of this is infinitely more interesting than drilling single word flashcards or being stuck in "Nouns 3" on Duolingo for weeks on end.

I think apps like Duolingo have their place, particularly when you're just starting out with a language. But too often, we forget that the key to language learning is making sure that what you're learning,


This is the beauty of Immersion. There are thousands of books that you will find interesting or helpful for your state of life, in just about any language you can imagine. You can download them and import them into Immersion, which will give you all the tools you need to make the most use of them.

To keep this tool free, I've set it to keep all your content stored locally in your browser. This means you should make use of the "export backup" tool frequently, in case your browser's cache is wiped. This local storage model has the benefit of all your lessons being yours alone.

If you want to get the most out of Immersion, you'll need an OpenAI API key. You'll want to go to this site: https://openai.com/api/ and get an API key. You'll need to load some money into the account. Start with the minimum, which was $5 at the time of writing this, and that should last you just about forever. Feel free to use the tool without AI built-in too, it still has a ton of utility!
