Mastering a New Language - An Introvert's Guide

4 min read

Learning a language as an introvert can be challenging, mainly due to the fact that one of the best methods for language acquisition is to interact with natives and those who are fluent in the language. However, due to that not being an option for some, in this article, we will be talking about how you can learn a language, without even leaving the house.

Frequently Asked Questions

LangX is available for free on ios, android and on the web app.

Yes, our app is free and 100% open source.

While our app is free and 100% open-source, we plan to introduce a subscription model for our Language Copilot feature. This feature, powered by OpenAI, provides real-time feedback during conversations, enhancing the language learning process. All other features will remain free. We also accept open sponsors on GitHub Sponsors.

As for monetization upon achieving significant growth, scalability becomes crucial, right? Take, for instance, the our Language Copilot feature I mentioned. It utilizes GPT, which requires an API and incurs costs on a per-word or per-token basis, as you're likely aware. Without implementing a subscription model, the expenses could quickly deplete my resources.

Therefore, in our roadmap, post-beta stage, we intend to introduce a subscription fee exclusively for accessing this feature. All other features will remain freely available for lifetime use. Unlike Tandem, which sells features lacking added value such as "Who viewed my profile?", our 🤖 Language Copilot provides direct feedback within conversations, enhancing the language learning process by enabling users to improve in real-time during authentic conversations with other users.

LangX sets itself apart by offering a comprehensive and community-driven platform that prioritizes language practice and user privacy. As a 100% open-source alternative to similar apps, we're committed to providing a seamless language learning experience while empowering users to take control of their data and privacy settings.

Harness the power of AI to accelerate your language learning journey. Get personalized feedback privately. It is going to be your private language copilot. There will be a toggle button in the top right corner of any chat room. When you open it, it feedbacks you privately when you are practicing with a real person in a room. Only you can see these feedback messages within the room. These messages are going to be different colored. I'm so excited about this feature because it speeds up your active language learning process. Stay tuned for more!

The innovative 'Learn to Earn' Token Project, for more info please visit:

We implore anyone to contribute, whether it’s just a single image, down to a single line of code/text. You can read more here on how you can add your contribution.

We actually have an excellent team of contributors who are dedicated to making valuable contributions wherever possible. With that said, if you are interested in taking on the role of our first moderator as a contributor/volunteer, please reach out for details. We can also begin delving into this matter together.

We'll definitely add sign languages to the study languages section during the registration process. Additionally, we have a contributor who works as an accessibility manager and can help with the following issues. Thank you for bringing this matter to our attention again :)

Regarding developing standards like WCAG with the W3C: Link.

This project has been a labor of love, and we're continuously updating and improving LangX to better serve our users' needs daily. We have exciting features in the pipeline, including AI-driven language learning support, and we're thrilled to share them with you in the near future.
