Comparison

vaken vs CastIChing: AI interpretation or pure Wilhelm text?

CastIChing publicly removed AI from their I Ching app and wrote a manifesto about why. vaken does the opposite — AI is the core interpretation layer. The choice between them is the choice between two valid traditions of I Ching practice.

Where vaken wins

  1. 01

    The reading is about your specific question

    CastIChing gives you the Wilhelm translation. vaken interprets that translation through what you typed. Ask "should I leave this job" and get Hexagram 4 — vaken's reading is about leaving the job; CastIChing's reading is the unaltered Wilhelm text. Both are valid; they serve different uses.

  2. 02

    Account-based reading history

    CastIChing is stateless by design. vaken saves every reading you cast so you can return, compare across time, and notice patterns.

  3. 03

    Modern situational interpretation

    Every vaken hexagram page has both the Wilhelm text AND a modern situational reading explaining what the hexagram is saying about life decisions, not just abstract symbolism.

  4. 04

    Funded continued development

    vaken's paid tier funds ongoing content work — comparison pages, blog articles, expanded hexagram coverage. CastIChing is free-forever, which is great but limits content velocity.

Where CastIChing wins

  1. 01

    It is free, forever, no account

    Zero friction, zero recurring cost. If you want the Wilhelm text and only the Wilhelm text, that's a complete product.

  2. 02

    Wilhelm purism

    The text is presented unaltered. No AI gloss, no modern reframe, no marketing layer. If that's what you came for, CastIChing delivers.

  3. 03

    The manifesto is worth reading

    Their "Why I Removed AI" post makes a real argument about AI's role in divination. Read it before deciding which app fits your practice.

Which to pick

If you've practiced the I Ching for years and you want the Wilhelm text without an AI interpretive layer, use CastIChing. If you're using the I Ching for specific decisions and you want the text refracted through your actual question, use vaken. Some people use both — CastIChing for study, vaken for live readings.

Decide by casting, not by reading
