Mr. B — the teacher behind Big Brain Labs
From the founder

Built by a working teacher

Big Brain Labs began because everyday classroom tools were too complicated, too expensive, or designed by people far removed from classrooms. Each app starts with a real school problem and is refined through actual classroom use.

“I polish every tool until I'm proud to use it with my own students. Then, and only then, does it go on the internet.” — Mr. B, K-12 teacher & founder

FAQ

The short, honest answers.

What is Big Brain Labs?

Big Brain Labs is a growing toolkit of simple classroom apps built by a working teacher. The lead product is brb. — a bathroom and hallway sign-out kiosk. One All-Access subscription unlocks brb. and every tool, with new tools included automatically.

What does the subscription include?

Yes — one All-Access subscription ($4.99/month or $39.99/year) unlocks brb. and every Big Brain Labs tool, with new tools added automatically. Cancel anytime. Master Scheduler (for school leaders) is sold separately.

Do students need accounts?

Most tools work without an account. A Big Brain Labs account is used for the brb. kiosk and any tools that need syncing across devices. Students never need accounts.

Does it work on Chromebooks?

Yes — every app runs in the browser. No installs. Works on Chromebooks, iPads, school PCs, and personal devices.

How is student data handled?

Designed to support FERPA, COPPA, and NY Ed Law 2-d compliance. Local-first by default — student data lives in the teacher's browser unless a feature explicitly needs cloud sync. No ads. No selling student data. A signed Data Privacy Agreement is available on request for districts.

Can schools purchase licenses?

Yes. Schools and districts can request a quote by emailing support@bigbrainlabs.org. We support POs, signed DPAs, and W-9 requests.
