About
Tl;dr its CanvasHack + CanvasCracked minus the paywall made by developers of CloakGPT.ca --- 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.
