LingoLog: Vocabulary Builder
Save words you read in Safari
Free · In‑App Purchases
Read Japanese, Korean, Spanish or another of 12 languages in Safari and look up words as you go. See what each word means in that sentence and save it with the passage.
Reading Japanese, Korean, Spanish or another language you're learning in Safari? When you find an unfamiliar word, select it to look it up with LingoLog. You can see what it means in that sentence, explained in your own language, and save the explanation with the original passage. Open the app later to review the words you looked up.
Looking up words and sentences
Enable the Safari extension using the guide in the app. Select a word or phrase on a web page, then use LingoLog to look it up and save it. AI explains the meaning using the surrounding text and provides examples and related expressions. Select a whole sentence for a translation, simpler wording, and notes on grammar and vocabulary.
Your saved words
Each entry keeps the original passage and source alongside the explanation. If you look up the same word in another article, you can keep both explanations. Search your collection, mark favorites, or use filters and sorting to find an entry. You can also select words in the app's examples and explanations to look them up.
Flashcard review
Review up to five saved words or phrases at a time. Read the original passage, try to recall the meaning, then reveal the answer. Mark whether you remembered it to set the next review date. Daily reminders are optional.
Languages
You can study English, Japanese, Simplified Chinese, Korean, Spanish, French, German, Italian, Portuguese, Vietnamese, Thai, or Indonesian. Choose your native and learning languages to see explanations in either language or both. The app interface is available in English, Japanese, and Korean.
