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.
Cyrillic is the first wall; cases are the second
A lot of learners stall before they ever read a paragraph, because the alphabet still feels like a puzzle. Once the letters settle, the next stall is morphology: the same stem in six cases, verbs of motion, and aspect pairs (говорить / сказать) that English treats as one word.
Seeing улица on an English page, then на улице on a Russian one, is how the prepositional stops being a chart. Prices, dates, and “of” phrases in news Russian are where genitive actually lives. A hover there is more honest than another list of endings.
Because Cyrillic does not look like English, the extension can tell the two sides of the pair apart on mixed pages more reliably than it can with two Latin languages. Read English and see Russian; read Russian and see English.
English ↔ Russian is live
English → Russian and Russian → English are both in the language picker. All 12 languages work with English. Spanish, Portuguese, French, German, Italian, Dutch, 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 replace a tutor or claim to teach handwriting. It is a reading overlay for people who already spend time in the browser and want Cyrillic words to stop being shapes.
Questions
Does it work on Russian-language websites?
Yes. English → Russian and Russian → English are both in the picker. On a Russian page the pair can flip so Russian words gloss into English. Cyrillic is distinctive enough that mixed pages are easier to tell apart than two Latin languages.
Will it teach cases?
It shows the form that is actually on the page. You will see genitive on a price, accusative on an object, prepositional after в/на. It does not open a case table or quiz you.
What about aspect (говорить / сказать)?
You will meet both members of a pair in real text. The hover gives the meaning in that sentence. It does not promise a lecture on imperfective vs. perfective.
