## Overview

Word Mentor is a Chrome extension built specifically for people learning English, and its central idea is removing friction from looking words up. Rather than selecting text, opening a dictionary site and pasting, you hover the cursor over a word on the page you are already reading and a popover shows the translation and definition. That applies to ordinary web pages and to online PDFs opened in the browser, which matters because academic reading is often distributed as PDF.

Vocabulary support is exam-oriented: the extension covers lists for TOEFL, IELTS and other examinations, so learners preparing for a test can meet those words in the wild rather than only in flashcards. Definitions in the popover come from WordNet, the lexical database from Princeton University, giving a reputable reference for word senses, parts of speech and related forms. There is also an optional ChatGPT-powered lookup for a word's root, affixes and practice exercises, which makes the tool more of a study aid than a plain translator.

The extension is offered by an individual developer (perry.lei), is free, and its Chrome Web Store listing has been stable with a 5.0 rating across a small number of reviews. It supports English and Simplified Chinese interfaces and declares that it does not collect or sell user data.

## Pricing & Plans

Free. The Chrome Web Store listing shows no paid tiers or in-app purchases.
