Philosophy

Your presentation.
Your browser.
Your data.

No cloud. No accounts. No tracking. Nonlinear runs entirely in your browser. Your slides, camera feed, and recordings stay on your device. Nothing is uploaded, stored, or analyzed by anyone.

We believe presentation tools should be as simple as opening a webpage. That’s why Nonlinear has zero dependencies, zero installs, and zero cost.
