What Kogvio is

Kogvio is a Chrome extension that places an intelligent on-screen overlay over the page you are already viewing. Its stated purpose is to help users understand highlighted content faster, especially when they are working through diagrams, advanced math, or technical documentation.

The product is built around a simple workflow: highlight part of the screen, trigger the extension with Cmd/Ctrl + Shift + E, and get an AI-generated explanation without leaving the active tab. The site also references a free Chrome install flow and a paid Pro subscription for advanced AI vision processing.

Core features

Inline screen analysis

Use Kogvio as an on-screen overlay to interpret highlighted screen content without switching away from the active tab.

Highlight-to-understand workflow

Highlight any screen area to send snippets for AI processing and receive an instant response based on what is visible.

Keyboard-first activation

Work from a keyboard shortcut, Cmd/Ctrl + Shift + E, so you can trigger the tool without relying on the mouse.

Technical content support

Use the product to decode complex diagrams, advanced mathematics, and technical documentation, according to the homepage copy.

Pro Vault storage

For Pro users, scan data is encrypted in a personal Vault, which indicates a separate protected storage flow for processed snippets.
