WordLenz

WordLenz turns the words you highlight or underline in foreign-language books into a personal vocabulary notebook.

Just snap a photo — WordLenz finds the highlighted word or sentence, detects the language automatically, and explains its meaning, nuance, and example sentences in the language you choose. Everything is saved and scheduled for spaced-repetition review, so it actually sticks.

• Capture highlighted/underlined words with your camera • AI explanations: meaning, nuance, pronunciation, examples • Snap words from books in ANY language — the source language is detected automatically (English, Japanese, French, and more) • Read meanings and examples in YOUR language — choose from 100+ languages: English, 한국어, 日本語, 中文, Español, हिन्दी, ไทย, and many more • Organize words into books (folders) • Spaced-repetition review (SRS) • Native pronunciation (text-to-speech) • Your data stays on your device — no account, no server, no ads • Use your own AI key (Google Gemini, OpenAI, Anthropic, or Qwen)
