• Smart Vocabulary Builder: Any new words encountered during reading—along with their AI-generated definitions and original context—are automatically saved to a built-in vocabulary list, making it easy to review and reinforce your learning later.• Smart Vocabulary Book: New words encountered while reading, along with AI definitions and the original context, can be automatically saved to the built-in vocabulary book for easy review and reinforcement later.

### 5/5 — Very useful

*2026-05-08*

The AI analysis is excellent.. I've already started using it to read some challenging long novels. But online translation is sometimes a bit slow (probably due to my network connection), I hope an offline translation function can be added.
