Diop: learn a language by reading what you love

Diop is a free app for learning a language by reading books and manga. Hold any word and Kyandi, your AI jellyfish tutor, tells you what it means in that sentence. Save it, and it comes back as a flashcard. Diop turns any PDF or EPUB into one column that fits your phone, and opens manga and scanned pages panel by panel.

AI and the human heart: China and the West

A curated collection that starts from classics that asked the machine question first (the Zhuangzi's "machine-heart", Aristotle's self-weaving shuttle, Butler, Shelley, Forster, Čapek, Confucius and Mencius) and follows today's debate in Chinese and English: Zhao Tingyang, Liu Yongmou, Zhu Songchun, Iason Gabriel and others.

What you can do

• Hold any word to see what it means, or reveal a sentence one word at a time.
• Practise the words you looked up as flashcards that come back just before you forget them.
• Read manga and scanned pages panel by panel, and select the text in the bubbles.
• Read any PDF paper as one column, with figures and headings in place.
• Tap a citation to see the full reference without losing your place.
• Search for any word and step through every match.
• Highlight in four colours and add notes.
• Listen with read-aloud while each line lights up.
• Get a summary from Claude, ChatGPT, Gemini or Grok, using your own key.
• Read free classics from Project Gutenberg: Laozi, Confucius, Gibran, Equiano, Du Bois and more.
