How it works
Enable the extension on a site you read. It highlights useful words in the article, not a separate lesson window. Hover a highlight to see the meaning. Chrome itself stays in English.
The loop is short on purpose:
- Words that are worth noticing get a highlight.
- Hover (or tap the highlight) for the translation.
- Keep reading. The page does not become a worksheet.
Coverage is a slider, not a promise that every word will change. Identical lookalikes that already match (the ones that teach you nothing) stay unmarked.
What Portuguese learners trip on in real text
Classroom Portuguese is neat. A G1 headline or a product changelog is not. You meet nasal endings (ão, ões), clitic pronouns stuck to verbs (fazer-se, disse-lhe), and the personal infinitive that textbooks mention once and news sites use constantly.
Spanish speakers have a second problem: they skip the word because it “looks obvious,” then guess wrong. Pasta is still pasta; escritório is an office; ration is not how you say ratio. Seeing the Portuguese on an English page — or the English on a Portuguese page — puts those misses next to the sentence that caused them.
Most of the Portuguese web you will actually read is Brazilian: news, stores, docs, forums. European Portuguese is real; it is just not a separate switch in this extension. If you already live between the two, treat the hover as a gloss, not a spelling authority for Lisbon.
English ↔ Portuguese is live
English → Portuguese and Portuguese → English are both in the language picker. Read an English page and see Portuguese. Read a Portuguese page and see English. All 12 languages work with English: Spanish, French, German, Italian, Dutch, Russian, Japanese, Chinese, Korean, and Arabic are bidirectional (EN↔). Hebrew is English → Hebrew.
What this is not
It is not a course, a streak, or a classroom. It does not invent a daily lesson plan or drill verb tables. It does not replace speaking practice, and it does not claim European and Brazilian Portuguese as two products. It is a reading overlay for people who already spend time in the browser and want some of those words to stick.
Questions
Brazilian or European Portuguese?
The live pair is English ↔ Portuguese. Speech uses a Brazilian Portuguese voice, which matches most of the Portuguese you will meet on the open web. There is no separate European-Portuguese mode, and spellings that differ (fato / facto, ação / acção) are not a second product.
I already speak some Spanish. Will that get in the way?
Often, yes — and that is why a hover on a real page helps. Spanish and Portuguese share a lot of vocabulary, then diverge on the words that matter (office vs. escritório, not oficina). The extension marks useful Portuguese, not every cognate you already recognize.
Can I read a Portuguese page and see English?
Yes. English → Portuguese and Portuguese → English are both in the picker. Read an English article and see Portuguese glosses, or open a Brazilian news site and see English.
