Overview / Description
ContextLens is an AI-powered Chrome extension that gives context-aware explanations for words or phrases you highlight on any web page. Unlike a traditional dictionary extension, ContextLens sends the page title to the AI so the explanation fits the specific topic you're reading. Highlight "hierarchy" while studying a feudalism article and it explains the term in terms of feudal lords, not a generic definition. The extension requires no setup and no API key — install it and start highlighting right away. It's aimed at students, researchers, and anyone who reads dense or unfamiliar material online and wants definitions that actually match the context they appear in.
