Yomitan is a browser extension that transforms your browser into a powerful language learning tool by providing instant dictionary lookups when hovering over foreign text. Originally developed as the successor to the discontinued Yomichan project, it maintains all the beloved features while adding modern improvements and expanded language support.

Ideal for any level of language learneing, for those engaged in immersion reading, especially those using Anki for spaced repetition and anyone needing reliable offline dictionary access during extensive reading sessions.

Install the extension from Chrome Web Store or Firefox Add-ons, then download dictionary files from the Yomitan website or community collections and import them through the settings page. Configure audio sources and Anki integration if desired.

Hold the Shift key and hover over any foreign text to trigger an instant popup with definitions, readings, and audio pronunciation. Click the speaker icon to hear native pronunciation, use the Anki button to create flashcards directly, and press Esc or click elsewhere to dismiss the popup.

Enable frequency dictionaries to prioritize common words during lookup and customize keyboard shortcuts for faster workflow. Consider importing both bilingual and monolingual dictionaries for comprehensive coverage.
