ftak

ftak is a free Chrome extension for understanding what you read online. Double-click or drag over any word or phrase and a small tooltip shows its meaning, a short summary from Wikipedia, and a map preview for places, all without leaving the page or signing up. The ftak site also has a PDF reader with the same lookups, and UPSC aspirants can see related previous-year questions for text in news articles. I'm a solo maker and built it for friends preparing for UPSC, and for anyone researching a topic or writing a story.
