Language Annotator turns everyday browsing into real language learning.

Add words quickly with translation, lemma, and dictionary support.
Translate words, phrases, and sentences without leaving the page.
Automatically collect and manage real example sentences.
Review vocabulary in the popup, fullscreen manager, and Practice Mode.
Sync your learning progress across devices.
How to use:
Open Settings and choose your source language.
While reading, select text to view translation directly on the page.
Right-click a word to save it to your vocabulary list.
Keep browsing. Saved words will appear highlighted again, and useful example sentences will be collected automatically.
Review your words later in the popup, the fullscreen manager, or Practice Mode.
Language Annotator is designed for serious learners who want vocabulary to grow through context, repetition, and active recall.

- This extension is really helpful for learning new words while browsing. I like how it lets me highlight and save vocabulary directly from webpages, which makes studying feel more natural and integrated into daily reading.

- When I wanted to translate a word or a webpage, I used to go to Google Translate. But with this extension, the translation is done through highlighting. I tried highlighting, and it really sped up the translation process.

- I really like that it highlights words directly on the page so I don’t have to keep opening new tabs for translations. I do have some problems with it though—sometimes the dictionary doesn’t show up, and I have to click the word over and over to get the meaning, which is super annoying. Also, the practice mode feels a bit boring, and I wish it were more like a game because right now it just feels like regular flashcards.

- Asifur Rahman
- here are a few minor things that could be better, though. Sometimes the dictionary lookup doesn't trigger on really niche websites, and the UI in the fullscreen manager feels a little bit crowded when you have a ton of saved examples. I also noticed that the cross-device sync can be a bit slow to update if I switch from my laptop to my desktop right away. But honestly, for a free tool that turns every Wikipedia or news article into a personalized lesson, it’s worth it. It’s definitely helped me move away from basic translations to actually understanding the nuance of new vocab
