There are a ton of paid courses about anything and everything swarming the Internet these days. They could be good or bad, but there are also totally free options for learning new things. Some of them are in the format of funny and interesting open-source software applications, available for everyone.
From languages to planets, it’s possible to access these learning tools just by downloading them for mobile or desktop. Afterward, if you enjoyed your experience and found it useful, you can consider donating some coins to their developers via
For now, let’s check some convenient free learning software developed by volunteers and available for immediate and free use.
Alpheios
If you’re interested in ancient cultures and literature, the set of tools provided by the Alpheios Project could fit your needs. This open-source initiative offers free-to-use software to support the study of classical languages, particularly Latin and ancient Greek, but also Arabic and Chinese. They’re also planning to include Persian, Syriac, and Hebrew next.
One of the key features of Alpheios is its modular design, which allows for the integration of additional languages with the necessary digital resources, such as morphological analyzers and dictionaries. Established in 2007 by Mark Nelson, the Alpheios Project initially received funding from his company, Ovid Technologies. However, it quickly became a non-profit by itself, and now relies on donations to keep running and improving. You can find them on Kivach as
Celestia Project
There’s a universe full of wonders outside Earth, and Celestia was developed to show it to everyone. This is a space simulation software that allows users to explore the universe in three dimensions. Released in 2001 by Chris Laurel, Celestia offers a detailed and accurate representation of the solar system, stars, galaxies, and other celestial objects. Users can navigate freely through space, zoom in on planets, moons, and asteroids, and even travel to distant galaxies.
Laurel initially developed Celestia as a hobby project, but it quickly gained popularity among space enthusiasts and educators. The software is currently supported by a community of developers and contributors who continue to enhance its features and expand its database.

Kiwix
Offline digital knowledge is likely something you’ve craved more than once, and Kiwix can provide this exactly. This is a program designed to provide offline access to web content, including Wikipedia and any other library added by users in over 100 languages. Developed by Emmanuel Engelhart and Renaud Gaudin, Kiwix was first released in 2007. It can download and store compressed web content locally, allowing users to access it without an Internet connection later, at any time.
Funding for Kiwix's development primarily comes from grants, donations, and contributions from organizations and individuals passionate about increasing access to knowledge worldwide. Kiwix has partnered with organizations like the Wikimedia Foundation to provide offline access to Wikipedia, furthering its mission to make knowledge accessible to all, regardless of Internet connectivity. They accept donations in fiat money (USD, EUR, CHF), but you can choose to send them cryptocurrencies as well
The Mnemosyne Project
There’s a thing called spaced repetition learning: a method scientifically proven to enhance long-term memorization. It’s often done with simple flashcards, where the new ones and the most difficult to learn are shown more frequently than the ones already memorized.
Initiated by Peter Bienstman, the project was first released in 2006. Its main feature is the implementation of spaced repetition algorithms, which optimize the timing of reviewing flashcards based on the user's performance, ensuring efficient memorization over time. It also offers stats, plugins, and a user-friendly interface for creating, organizing, and reviewing flashcards, making it an invaluable tool for students, language learners, and anyone seeking to memorize large amounts of information.
Funding for the Mnemosyne Project primarily comes from donations and contributions from its user community. You can send them some coins via Kivach, just by looking up
Tux4Kids
In case you don’t know, “Tux” is the famous Linux mascot penguin. He’s the image and protagonist of Tux4Kids, a collection of free and open-source educational software aimed at children —but also enjoyable by adults. The project was founded by Bill Kendrick and began in 2001 with the release of Tux Typing, a typing tutor game featuring the penguin.
