In everyday school life, there is often too little time to cater to students individually – a problem many teachers are familiar with. This is where the Würzburg startup Living-Lines comes in: With the help of artificial intelligence, the app assists teachers in better enabling individual learning in math classes.

The idea originated from personal experience. Founder Jakob Seitz grew up in a teacher's household where challenges in the education system were regularly discussed. Together with his colleague Tobias Lengfeld, he then developed a solution that eases the burden on teachers while specifically promoting learners.

AI recognizes handwritten calculations

The core of the application is an AI that can analyze and understand handwritten calculation methods. Teachers photograph assignments, and the software converts them into digital worksheets. Students then work on them handwritten on tablets. In case of errors, the app provides immediate feedback – without giving away the solution.

The special feature: The AI not only recognizes results but also the solution path. This creates a learning experience that feels like individual tutoring for many.

Close collaboration with schools

Since the start of development in 2024, the team has been working closely with schools. Living-Lines is already being used in several high schools in Schweinfurt, Würzburg, and Hösbach.

The feedback is positive: teachers report significantly reduced correction effort and more time for personal attention in class. At the same time, heterogeneous classes benefit as both stronger and weaker learners receive tailored support.

Promotion and Future Vision

Since January 2026, the founding team has been supported by three EXIST start-up grants from the Federal Ministry for Economic Affairs and Energy, co-financed by the European Social Fund. The funding allows the team to focus fully on the further development of the app and the preparation for market entry for one year.

The startup is also supported by the University of Würzburg, particularly the Chair for Computer Vision headed by Professor Radu Timofte, as well as the founding consultation of the Service Center for Research and Technology Transfer.

By the end of 2026, the Living-Lines team aims to further expand, gain additional schools, and functionally enhance the app – for example, through gamification elements. In the long term, the startup pursues a clear goal: to support teaching so effectively that less tutoring is needed and students sustainably understand content directly in class.

The potential of Living-Lines has already been recognized multiple times.
