Stop Wasting Your Time In Endless Searches
Just Highlight It!
Defin, the AI-powered Chrome extension, delivers instant definitions and explanations when you highlight any text on the web.
The Problem with Traditional Searches
Every time you open a new tab to look up something, you risk:
Losing Time
Endless scrolling through search results and clicking multiple links makes finding answers time-consuming.
Getting Distracted
Promotions, Ads and other irrelevant content can pull your attention away from what you were reading.
Breaking Focus
Switching between tabs disrupts your reading flow and reduces productivity.
How Defin Solves This Problem
