About WordPopup

WordPopup is a lightweight reading assistant and dictionary that helps you understand unfamiliar words without interrupting your reading.

Why we built it

Looking up a word usually means opening a new tab, searching, and then finding your place again. WordPopup keeps you on the page: select a word, read its meaning, and keep going.

What it does

• Shows meanings, pronunciation, synonyms and examples in a popup.
• Supports English and German dictionaries.
• Lets you save and highlight words to build your vocabulary.
• Exports your saved words as a TXT file.
• Works on webpages with the Chrome extension, and on PDFs here.

Your privacy

Your saved words and history stay in your browser, and your PDFs are never uploaded. Read the full privacy policy.
