"Finally, a tool that understands I'm learning European Portuguese, not Brazilian. The CEFR filtering is exactly what I needed to focus on the right vocabulary."
"I read Portuguese news every morning with my coffee. This extension turned passive reading into active vocabulary building. My B2 exam prep is so much easier now."
"The cognate filtering is brilliant. It only shows me words that are actually new, not the ones I can already guess from English or Spanish."
European Portuguese. The vocabulary database, spellings, and CEFR assignments are specifically tailored for learners targeting Portugal. If you're learning Brazilian Portuguese, some words may not match your needs.
The levels are based on frequency analysis of Portuguese corpora combined with official CEFR vocabulary lists. While no system is perfect, the assignments have been refined through extensive testing and are reliable for learning purposes.
The extension requires an internet connection to look up words. This is a deliberate design choice that allows us to keep the vocabulary database secure and continuously improving.
