This pen offers multiple functions: real-time voice translation (you speak and it translates), text scanning and translation (you slide the pen over printed text and it recognizes, translates and can read aloud) and also recording/playing audio in some cases. For example, similar models scan large numbers of languages (55+ text languages, 112+ voice languages) and support WiFi for faster translations.

This means it’s useful for travel, study, business or language-learning.

It typically supports dozens of languages for text OCR-scan and many more for voice translation. For instance, one model supports text scanning of 55 languages and voice translation across 112 languages.

Note: Offline capabilities may be limited (fewer languages, smaller database) compared to when WiFi is connected, so for the best accuracy you’ll want an internet connection when using advanced language modes.

• Keep the pen charged (many models have built-in rechargeable lithium batteries). Ensure you use the supplied USB cable or charger.
  
• For scanning printed text: move the pen steadily over the text in a straight line—avoid very curved surfaces or highly glossy materials as they may affect recognition. Some users have reported limitations with vertical text. Reddit
  
• For voice translation: speak clearly into the microphone, and preferably in a quiet environment for best accuracy.
  
• Store the pen in a dry, dust-free place. Wipe the scanning tip and audio/mic region occasionally to keep it clean.
  
• If using offline translation features, update any firmware or language packs (if available) so you have the latest language databases.
