## Description

Online Dictionary Helper is a Chrome extension designed to enhance your reading experience by instantly showing online dictionary content. When you hover over an unfamiliar word on any webpage and press the Shift key, a popup window displays the word’s definition. This seamless access to meanings helps users learn new vocabulary efficiently without leaving the page.

Additionally, the extension integrates with Anki desktop (requires AnkiConnect) to facilitate quick note-taking. Users can create Anki flashcards automatically, with fields populated for the word, its definition, and context—the sentence surrounding the word. This feature supports effective language learning and vocabulary retention by bridging online reading with powerful spaced repetition flashcards.
