Semanty - Contextual Lookup
Explain word Contextually
Free · In-App Purchases
Select a word, get its exact meaning in context — not a dictionary list. Phrases recognized automatically. EPUB, PDF, web. Sentences become flashcards. No ads.
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 — 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 — 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 — 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

Clean and Quiet
No ads. No distractions. No social features. Just a calm space for reading and learning.

Semanty 2.0 is a complete redefinition — from a Safari-focused lookup tool to a full-featured foreign-language reading and vocabulary acquisition app. Available on iOS, iPadOS, and macOS.
Reading System
Import three formats: EPUB e-books, PDF files, and web pages via URL. One library, one reading experience. Powered by a custom native pagination engine for precise, fluid page turns.
Contextual Lookup
Select any word in the reader and get exactly what it means in that sentence — no more guessing through a wall of dictionary entries. More importantly: select just one word of a phrase, and Semanty recognizes the full expression and explains it.
Sentence Notebook
Every word and sentence you look up is saved automatically. No manual entry needed. Each record preserves the original sentence and its source. Your vocabulary grows around real reading moments.
Spaced Repetition
The review unit is the sentence, not the isolated word. You see the sentence as you first encountered it and ask yourself: do you understand? Context triggers memory far better than rote memorization. The system schedules your next review based on how well you know each item.
Pronunciation
Built-in pronunciation button in every lookup popover, supporting both words and phrases.
