About TeachShield

We believe teachers are the most overworked, underpaid professionals on earth. We built TeachShield to give you your evenings back.

Why we built this

We're a group of friends who watched teachers in our lives — partners, siblings, parents — spend their weekends buried in grading, lesson plans, and admin work. Thirty essays on a Sunday night. Progress reports due Monday. No time for the things that actually matter.

So we built TeachShield. Not as another corporate EdTech tool that promises the moon and delivers a complicated dashboard. We built a platform that handles the repetitive work — grading, lesson planning, worksheet generation, classroom games — so teachers can focus on what they do best: teaching.

TeachShield is a product of Obsidian Clad Labs LLC, a group of friends from Tennessee who believe software should solve real problems for real people. Simple. Affordable. Always on your side.

“Every teacher deserves tools that respect their time. Grading 30 essays shouldn't take all weekend.”
