A free website where you learn languages by exploring 3D environments

I've been working on a project called Lexi Explorer.

The idea came from frustration with how most language apps work. I've tried a few over the years and while they're good at introducing vocabulary, I forget most of it quickly. It feels like memorizing isolated words instead of actually experiencing a language.

So, I tried a different approach.
Instead of flashcards or lists, you move through 3D environments, a city, restaurant, classroom, and click on objects to learn their names in your target language. The goal is to connect words with context and space rather than just text.

Right now, it supports Spanish, French, German and Italian. Beyond the 3D worlds there's a personal vocabulary dictionary, sentence practice, mini games, and audio pronunciation. No login, no subscription.

Just open and start: Lexi Explorer

I've been sharing it with early users, and the feedback has been useful. The most common thing I hear is that the concept clicks immediately but people aren't sure what to do when they first enter a world. So, I'm working on better onboarding.

Here's a quick look at what it does: Lexi Explorer Launch Trailer

Some things I'm genuinely trying to figure out:

Does learning words in context actually help you remember them longer?
How much should the app guide you vs let you explore freely?
What makes someone come back for a second session?

If anyone has thoughts on language learning, memory retention, or just wants to poke around and share feedback, I'd really appreciate it.
