CAVOK: Study Buddy is a native Mac application designed specifically for students facing heavy reading loads and strict deadlines. By allowing users to drop in their own textbook PDFs, the app enables plain-language querying while strictly restricting answers to the provided text. It features precise page citations and a strict zero-hallucination policy—if the answer isn't in the source material, the app explicitly states that it doesn't know rather than guessing or filling in gaps.
Built with privacy at its core, CAVOK runs entirely on your device by default, requires no user account, and routes no data through external servers since no company-run servers are utilized. For users seeking deeper or more adaptive answers, an optional cloud mode can be enabled using a personal API key. Available as a native Mac app through a straightforward one-time purchase of $14.99, CAVOK bridges the gap between powerful AI study tools and absolute data privacy.
