About this extension
WHAT is a simple dictionary extension that helps you understand words while browsing.

Highlight a word on any webpage and WHAT can show its definition in a clean popup. You can also use manual mode, where highlighted words are saved and shown only when you open the extension.

Features:
- Highlight words to get instant definitions
- Choose between automatic popup mode and manual extension mode
- Select different dictionary languages
- Save words locally for later review
- Manage saved word history
- Clean yellow knowledge-themed interface
- No analytics, ads, or tracking

Saved words and settings are stored locally in your browser. WHAT only sends highlighted words to dictionaryapi.dev when it needs to fetch a definition.
