AI English · Web Text Translator

AI English · Web Highlight Translation is a completely free Edge/Chrome browser extension that allows you to immerse yourself in vocabulary learning and study while browsing any English webpage—be it news, blogs, technical documents, or social media—without switching apps or logging in. Install once and use immediately, with no need for activation keys or server configuration.

【Word Learning · Native Speaker Thinking】
Highlight an unfamiliar word, and the extension will automatically fetch dictionary definitions and generate 2–3 AI-created example sentences containing the word. This encourages you to first guess its meaning based on your own intuition. Only when you're unable to determine the meaning should you click "Show Definition" to reveal full phonetic symbols, audio pronunciation, Chinese translation, and the specific contextual meaning of the word within the original sentence (determined by AI based on surrounding context), enabling precise comprehension. You can also add words directly to your local personal vocabulary list with one click.

【Continue Looking Up Within Popups】
Inside the pop-up window, you can click on any word in the example sentences to initiate another lookup session, diving deeper into related terms—all without leaving the current page.

【Sentence Comprehension · Translation & Explanation】
Select an entire English sentence, and the extension instantly provides a smooth, natural Chinese translation. Click "One-Click AI Explanation" to automatically break down key grammar points, essential vocabulary, and idiomatic expressions, making complex sentences clear and easy to understand.

【Three Trigger Methods】
The extension supports three convenient ways to trigger lookups: a floating button appearing after text selection, a right-click menu option labeled "AI English," or the keyboard shortcut Ctrl+Shift+E (Command+Shift+E on Mac). Look up words anytime, anywhere.

【Local Personalization Settings】
Click the extension icon to access settings, where you can customize example sentence difficulty and quantity according to your proficiency level. Choose whether to auto-display definitions, auto-translate sentences, or show the AI explanation button. All preferences are saved locally, and your vocabulary list remains stored only on your device. The AI call limit is capped at 10 times per minute, with a 30-second pause enforced upon exceeding this limit, ensuring stable service performance.
