Localized Privacy & Zero Access
Your notes stay on your device. Your key is never sent to the site. Export anytime.
🛡 Sandbox Security — by design, not by promise
The Companion runs sandboxed inside your browser. The sandbox walls it off from your device, so it is virus and malware free by design — there is nothing to install, nothing that can touch your files, and nothing that phones home.
Sandboxed
Runs inside the browser's protected sandbox, sealed off from your device and files.
Nothing to install
No downloads, no permissions, no app-store setup, no background software — no installation complexity at all. Open the page and use it.
Virus & malware free
By design: sandboxed code cannot reach your system, so nothing malicious can ride along.
Zero access
Your notes and your AI key never leave your device and are never stored on any server.
💰 Zero cost — free forever
No subscriptions. No ads. No paywalls. No student-price cliff after graduation. Every student gets the full toolkit free, forever — donations only keep it that way.
