Overview
Kogvio is a Chrome extension designed to help people understand difficult on-screen content faster. Its homepage describes it as an intelligent overlay that can decode complex diagrams, advanced mathematics, and technical documentation without leaving the active tab.

Key capabilities
Content-aware understanding
The homepage specifically mentions support for complex diagrams, advanced mathematics, and technical documentation.
Highlight-based input
Users can highlight any screen region to trigger analysis, making the tool focused on selected visual content rather than full-page browsing.
Keyboard shortcut access
A keyboard shortcut, Cmd/Ctrl + Shift + E, is shown on the homepage for quick access without relying on the mouse.
Temporary scan processing
The privacy policy says scan snippets are processed in real time and deleted from the server within 24 hours.
Pro Vault storage
The privacy policy states that Pro users have scan data encrypted in a personal Vault.
Common use cases
Studying dense material
A student can highlight a difficult formula, diagram, or explanation and ask for help without leaving the browser tab they are already using.
Working through documentation
Someone reading technical documentation can keep the reference page open while using the overlay to make sense of a specific section or visual.
Fast, mouse-light assistance
A user can use the keyboard shortcut to quickly launch the tool during active reading or problem solving, reducing context switching.
Reviewing saved scan data
A Pro user who wants persistent access to prior scan data can rely on the Vault storage mentioned in the privacy policy.
