Lexigo: AI Dictionary, Vocabulary Builder & Save Words

Save words as you read — definitions, audio & AI explanations in your language — then remember them with spaced repetition.

Detailed Description Lexigo is a vocabulary builder (19 languages) that turns the pages you already read into words you actually remember. Hit an unfamiliar word in an article, email, doc, or PDF — select it, and Lexigo captures it in one click with its definition, pronunciation (IPA + audio), a translation in your language, and the exact sentence you found it in. 100% FREE 🆕 AI explanations: Not sure what a word means here? Click “Explain with AI” and Lexigo tells you what it means in that specific sentence, in your native language — the nuance a plain dictionary misses. Two ways to save a word: • Select it and click the floating “Save to Lexigo” button • Right-click the selection → “Save to Lexigo” What Lexigo keeps for every word: • A clear definition, fetched instantly • Phonetic spelling + audio so you can hear it • A translation in your language (19 supported) • An AI explanation of the word in its original sentence • The sentence and source page you found it on • Collections to group words — Business English, Travel, Academic, and your own Remember what you save Capturing a word is only half the job. In the free Lexigo web app, a two-minute daily review brings each word back right before you’d forget it, using spaced repetition (the SM-2 algorithm) — two simple buttons, “Forgot” or “Got it.” No decks to build, no Anki setup. Streaks, XP, levels, and a contribution heatmap keep the habit going.
