Learniva is developing an interactive agent-based platform for one-on-one tutoring in STEM subjects, with an initial focus on mathematics. On the platform, students create geometric constructions, solve equations, and draw graphs on their own. The AI tutor monitors their progress, identifies where they’re stuck, and helps them understand the next step. Learniva thus focuses not only on the result but also on the reasoning that leads to it.
The technology is made available directly to students through its own app, while also being offered to publishers for integration into their educational materials and platforms. The project was founded by Kristýna Coufalová, a graduate of the master’s program in statistics at the University of Oxford. Learniva combines her expertise in statistics and practical experience working with children with insights from educational research and close collaboration with educators. Its goal is to provide high-quality, individualized support to every student.
