Intelligent tools that make learning click.
Maritacas OÜ is an Estonian startup building and owning a portfolio of AI-powered learning products. Our first, ChessCoda, is live today at chesscoda.com, and more are on the way.
Technology that builds understanding
We believe the best learning tools should build insight, not just deliver answers. That principle shapes everything we make.
Our Own Products
We apply modern AI where it genuinely helps, building and owning products designed around real people and real problems. Everything we make is our own, not client work.
Built to Teach
Learning experiences that adapt to each person's pace and level, turning difficult subjects into approachable ones. A growing family of products, starting with chess.
