A student-focused WebOS that runs in the browser with draggable windows, a dock, dark/light mode, persistent state, and built-in tools like SAT Sprint, GPA Calculator, Final Grade Calculator, Notes, Study Timer, and ContextGuard Mini.

ContextGuard Lite is a local-first Chrome/Edge browser extension that helps users redact private information before using AI tools like ChatGPT, Claude, and Gemini. It can scan pasted text and simple uploaded files such as .txt, .md, .csv, and .json, then replace sensitive data like emails, phone numbers, passwords, API keys, student IDs, URLs, SSN-like numbers, and card-like patterns with safe labels. Everything runs locally in the browser with no backend, login, paid API, or tracking.
