Canvas Open is a free, open-source toolkit for Canvas LMS students.

PRIVACY GUARD
• Blocks all tab-switch and focus-loss detection — freely switch tabs without being flagged
• Spoofs visibility API, IntersectionObserver, and requestAnimationFrame timing gaps
• Removes hidden AI Trojan Horse spans instructors embed in assignment descriptions

QUIZ AUTO-FILL
• Automatically pulls your best previous answers from past quiz attempts via the Canvas API
• Fills answers on hover — supports multiple choice, true/false, fill-in-the-blank, matching, numerical, formula, essay, and more
• Never overwrites your manual edits

AI QUIZ ANSWERING
• Uses your own OpenAI API key (gpt-4o-mini) — no server, no subscription, key stays local
• Normal mode: click the AI button, see green/red dots on each answer
• Stealth mode: auto-runs silently with invisible hover indicators

EXTRA TOOLS
• Show UI overlay — floating "Protected" pill confirms the guard is active
• Kiosk mode — simulates a locked-down browser environment
• Blocked sites — exclude specific domains from injection

100% free. No accounts. No servers. No data collection. Everything runs locally in your browser.
