Built for teachers, by teachers
We built GapFiller because we know what teaching really demands. We wanted a tool that helped us think better, and when we couldn't find it, we built it.
Teaching is a craft: in a digital world full of noise, teachers need clarity, focus and tools that amplify their work instead of distracting from it.
GapFiller is our answer: a simple, powerful workspace designed to help teachers stay organized, plan with intention and reclaim their time.
