Leafy: An AI-Powered Vocabulary Builder for Screen Reading

Introduction

Leafy is a smart tool designed to help people learn new words while they read. It works directly on your Mac computer by letting you select any word on your screen. The app then uses artificial intelligence to read the whole sentence where that word appears. This method saves the word and its context together, building a personal vocabulary list automatically. You do not need to type anything or create flashcards manually.

Benefits

Leafy offers several advantages over traditional study apps. First, it creates vocabulary lists dynamically. When you look up a word, the app saves it along with the specific line it came from. This library is sorted and searchable without any setup. Second, the review process is unique. When you study saved words, the app hides the word inside the original sentence and asks you to fill in the blank. This helps you remember the word in context. Third, the tool supports many languages including English, Spanish, French, German, Italian, Greek, Chinese, Japanese, Thai, and Arabic. Finally, Leafy focuses on privacy. Your vocabulary library stays on your Mac and never leaves your device. The app has no account system and no ads.

Use Cases

Leafy is perfect for students, professionals, and anyone who reads a lot. You can use it with PDFs, ebooks, images, or any text displayed on your screen. For example, if you are reading a complex article in English or a book in Japanese, you can box a difficult word and instantly get an explanation. The app works on macOS 14 or higher. It is especially useful for people who want to expand their vocabulary without spending hours creating study materials. The ability to export your word lists to formats like JSON, CSV, Excel, PDF, or Anki makes it easy to share your progress or use it in other study tools.

Pricing

Leafy offers three pricing options. The free tier includes a limited amount of scanning. The developer covers the AI costs for this plan. The monthly subscription costs $6.99 per month or $3.49 per month if you pay annually. This tier allows for unlimited scanning with the developer covering AI costs. There is also a lifetime license for $49. With this plan, the user pays the AI costs directly when they use the service. Early adopters who choose the lifetime plan will keep the lower price permanently. Please note that the product is currently in beta, and no features are being sold yet.
