Cymbra Lingua
Spanish and French as you read
Free
The Spanish or French words you don't know yet, highlighted on the page you're reading. The analysis runs on your device, offline.
Cymbra Lingua is a Safari extension that highlights, on the page you are reading, the Spanish or French words you don't know yet — without changing the layout. A pill shows how much of the text is familiar to you, counted from what you actually marked rather than guessed.
AFTER INSTALLING
This app installs the extension; you still need to turn it on.
1. Open Settings > Apps > Safari > Extensions (on Mac: Safari > Settings > Extensions).
2. Turn on Cymbra Lingua, then allow it on the websites you read.
3. In Safari, open the extension from the address bar menu and choose your level of Spanish — until you do, the extension assumes you know no words at all. For French, check it in the extension's Settings, under Language, then choose your level of French.
Reload the tabs you already had open so they get highlighted.
READ
Tap a highlighted word: its meaning in English, its dictionary form and how rare it is in everyday use. The meanings come from Wiktionary, written by people, never machine-translated. The card also names the tense and the gender ("preterite indicative" in Spanish, "past historic (passé simple)" in French, "feminine noun"). Then decide — "I know it", "+ Deck" to review it later, or "Ignore". Select several words to capture a whole phrase with the sentence it came from.
REVIEW
The cards you make are reviewed in a panel beside your reading, with spaced repetition that picks the right moment for you. A statistics screen estimates your vocabulary level by level, from A1 to C2, from the words you have marked — for Spanish and French, levels estimated from word frequency.
READ YOUR BOOKS
Import your DRM-free EPUB books into the extension's library and read them offline, with the same highlighting. They stay on your device.
EXTENDED TRANSLATION (OPTIONAL)
Your selection is translated into English within its sentence, straight from Spanish or French, on your device, by the Firefox Translations engine, included in the app. Turning it on downloads from Cymbra, once, the translation model of each language you study (26.2 MB each); the text of the pages you read still never leaves your device. Turning it off deletes the models.
YOUR READING STAYS YOURS
The dictionaries and the analysis and translation engines are in the app. No page you read is sent anywhere, and everything works offline. Without an account or extended translation, the extension makes no network requests.
AN ACCOUNT, IF YOU WANT ONE
Create a Cymbra account if — and only if — you want your words and cards on your other devices. That is the only thing that leaves your device, and you can erase it from the settings without deleting your account.
How many Spanish and French words our dictionary explains in English: our figures are at cymbra.app/en/lingua.
The interface is in English for English speakers, who learn Spanish and French, and in French for French speakers, who learn English and Spanish.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Sign in from the app: with Apple, Google, or an email address and a password. Reviews done in the app sync with your other devices.
Review: "Edit card" corrects a card during review, and "End" stops the session in progress. A translation found at review stays on the card.
In Safari, the extension's icon can show the number of cards to review (Settings › Show the cards to review on the icon).
Anonymous usage counts: the extension sends a few usage counts, never what you read. You can turn them off in Settings (Send anonymous usage counts).
