Overview

Product summary

Review the store description, core capabilities, and common use cases.

Ever come across a word you don't know while reading online?

Instead of forgetting it or opening ten tabs to look it up later, simply highlight the word and save it instantly.

This extension lets you capture vocabulary directly from any webpage and build your own personal word bank while you browse.

Whether you're reading articles, studying, researching, or exploring the internet, you can collect new words naturally as you encounter them.

Learning vocabulary becomes effortless because it happens in the flow of real reading, not in a separate study session.
