Building tools for the everyday person.

About

After years in corporate tech, I saw that everyday people like teachers, contractors, freelancers and families were stuck paying for tools the big companies get for free.

TeachShield - Grade faster, plan better, teach more

Teachers spend 12+ hours a week on paperwork. TeachShield gives that time back. AI grading (30 seconds per essay, rubric-aligned), 31 infinite-worksheet types, lesson planner, Jeopardy review games, AI-detection, and a Symbolab-class math solver — one dashboard, real print output. Free tier: 50 actions/month, no credit card. Grader $3/mo. Built by a husband-and-wife team for the teachers in their life.
