You're reading something in a foreign language and hit an unfamiliar word. What do you do? Switch apps, type it out, scroll through a wall of dictionary entries, then guess which meaning fits β€” by then the reading flow is long gone. And if it's a phrase or idiom, a traditional dictionary likely won't help at all. Semanty takes a different approach: select the word, and get exactly what it means right there in that sentence. No guessing through lists of definitions. And even if you only select one word of a phrase, Semanty recognizes the full expression and explains it. Read Without Interruption Supports EPUB, PDF, and web page imports. Open a book, a paper, an article β€” tap any word or phrase you don't understand. No switching apps, no breaking focus. Just keep reading. Remember in Sentences, Not Words Every word and sentence you look up is automatically saved to your notebook. There are no isolated word cards here β€” each entry is the original sentence you encountered. When reviewing, you're not asked to recall a definition out of context. You see the sentence and ask yourself: do I understand this? That familiar moment brings the meaning back naturally. Spaced Repetition Built on a spaced-repetition algorithm. What you know well shows up less. What you struggle with comes back sooner. Progress you can actually see. Safari Extension Not reading inside the app? The Safari extension gives you the same tap-to-understand experience right in your browser. Clean and Quiet No ads. No distractions. No social features. Just a calm space for reading and learning.
