Kogvio
An AI explanation extension inside the browser: select difficult text or charts on webpages or PDFs and get explanations in place.
About Kogvio
Kogvio is a Chrome browser extension that works inside the browser as an intelligent screen overlay, directly explaining complex text and charts in webpages, online PDFs, and local files opened in the browser. Select confusing handwriting, diagrams, or dense paragraphs to get an explanation directly on the page, without opening a new tab or copying and pasting. It is designed for people who read challenging content every day: university students reading dense textbook PDFs, researchers reviewing technical papers, developers troubleshooting code, and medical students learning complex biological pathways. Kogvio runs on its own backend, requires no API key configuration, and lets you start scanning after logging in once; it works in Chrome, Brave, or Edge on a computer.
