05 / Who builds it

Built by students, for students.

CodeBrosAI started as a personal project to solve a real problem: students needing a calculator for class but switching to their phones every time they needed help.

Every unit is refurbished, modified, tested, and shipped by our team. Software updates roll out over Wi-Fi as the technology evolves.
