Nightspar — Vocabulary Flashcards from Any Page

Stop forgetting the words you look up. Select a word or phrase on any page and save it. Nightspar writes the whole flashcard for you — the meaning as it's used in that sentence, a translation, pronunciation, example sentences, and audio — then schedules it for review right before you'd forget. WHAT IT DOES • Save from anywhere — select text on any page and click the "+" button. No copy-paste, no tab switching, no interruption to your reading. • Cards that write themselves — every meaning, with its own translation and example. The definition describes the sense actually used in your sentence, not just the most common one. • Hear it — native-quality audio for every phrase. • Organize as you go — drop a phrase into a collection right from the save panel. • Spaced repetition that works — reviews are scheduled with FSRS, the same modern algorithm Anki uses. A few minutes a day. • 33 languages, several at once — each language pair keeps its own library and review schedule. • Your library, on the web too — everything you save syncs to nightspar.com. WHAT IT SAVES, AND WHEN When you save a phrase, Nightspar also stores a short snippet of the text surrounding it, plus the page URL and site name. This is what lets the AI pick the right sense of a word, and lets you see where you first met it. URLs are sanitized before storage: credential-like query parameters are removed and fragments are dropped. This happens ONLY when you explicitly save a phrase. The extension does not read, monitor, or transmit the pages you visit in the background, and it does not track your browsing. You can turn context capture off in the extension's settings at any time — with it off, only the text you selected is sent. Requires a free Nightspar account. Free during the beta.
