The final vision for MIA is twofold:

First—a series of self-contained articles that, when consumed in chronological order, will equip learners with everything they need to understand and apply the most efficient language acquisition techniques.

And second—an extensive toolkit of apps and programs that help learners automate and optimize the language learning process.

They have a lot of interesting and somewhat useful resources, but towards the end of 2020 their two creators (Matt and Yoga) decided to split up the partnership due to internal problems. The two new projects for each of them respectively are refold.la and Migaku.
