Open-source language learning tools


Ulangi makes it easy for you to manage and create flash cards to learn languages. It comes with built-in dictionaries, translators, built-in TTS, image search engine and more. You can use different learning methods to memorize them, such as spaced repetition, writing, quiz... Everything about Ulangi (mobile, server, add-on, etc) is hosted in this repository.

Ulangi is completely free thanks to Midterm App. We are going to use some technology from it to make the desktop version.
