Structure is everything

The Mentabacus is a learning tool that helps people remember complex information — not just word lists or trivia, but whole systems of knowledge like grammar rules, legal categories, or scientific structures. It's not another flashcard app.
 
It’s a learning environment — a method that combines objects, spatial placement, story creation, and visual diagrams to make knowledge stick.

In a world where memory often takes a backseat to search engines and fast learning, the Mentabacus invites us to slow down and build knowledge that lasts. It aims to support all kinds of learners, especially those who benefit from physical interaction, storytelling, or visual structure.

This makes the tool particularly helpful for anybody who struggles with knowledge that is presented in a merely abstract-verbal manner.

The most disadvantaged learners in terms of abstract-verbal capabilities will benefit most.

Everything is structure

    Mentabacus Whitepaper – Why and how “thinking inside the box” can change the way we teach complex knowledge (about 100 pages of in-depth background for investors, educators, policymakers, and edtech leaders.).     The whitepaper has been finalized and is now undergoing a final round of rigorous external review to ensure that Mentabacus meets the highest standards of accuracy and credibility.
