Description
Select any word to get a context-aware definition powered by AI. Uses the page content to give you the right meaning. WordLens gives you instant, context-aware definitions for any word or phrase on the web — not just a dictionary lookup, but an AI explanation that actually understands what the page is about. HOW IT WORKS Select any text → press Alt+D (or right-click → "Define with WordLens") → a tooltip appears with an explanation tailored to the context of the page you're reading. Example: "model" on a machine learning blog gets a different explanation than "model" on a fashion website. WordLens reads the page first, then explains.
