Two apps for students and one service for schools.
GPAI
AI agent for university students
gpai.appStudents connect their school’s course portal and GPAI pulls in lecture materials, videos, assignments and announcements. It answers questions from their own courses, flags what is due today, writes reports, study notes and slides, and lets teammates edit the same document together.
In September 2026 GPAI opened to students in every major, not only STEM, and made its previously paid features free.
