About CAVOK: Study Buddy
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.

About Islet
Islet is a native macOS utility developed by solo indie maker Lippi304 that brings the popular iPhone Dynamic Island experience directly to your Mac's notch. Unlike conventional notch utilities that merely draw a static shape over the camera cutout, Islet provides dynamic, interactive behavior powered by native spring-physics for smooth expansion and collapse animations.
Built natively using Swift and AppKit rather than heavy frameworks like Electron, Islet is designed to be lightweight, fast, and fully fullscreen-aware. It features real-time heads-up displays (HUDs) for volume and brightness, a live music glance with full playback controls, and convenient one-tap audio output switching that saves you from navigating through System Settings.
In addition to media and system controls, Islet incorporates helpful daily widgets including calendar and weather glances, as well as a versatile file tray that allows you to drag and drop files from anywhere on your system.
