How to choose
If you want AI interpretation
Use vaken or yarrow.life. Both use AI to read your hexagram through the specific question you typed. vaken is paid ($9.99/mo or $79/yr) with a free tier; yarrow.life is free without a visible paid tier. vaken's brand voice treats the I Ching as a decision tool; yarrow.life leans toward daily-ritual guidance.

If you want pure Wilhelm/Baynes
Use CastIChing. They publicly removed AI from their tool and present the Wilhelm text unaltered. Free, no signup, stateless. The right choice for purist I Ching practice. See vaken vs CastIChing →
If you want Tarot, not I Ching
Use Labyrinthos. Beloved Tarot, Lenormand, and astrology app with decade-deep content and physical decks. Note: Labyrinthos does NOT have I Ching. If you want I Ching alongside Tarot, you'll need both Labyrinthos and an I Ching-specific tool. vaken vs Labyrinthos →
If you want reference, not guidance
Use ichingfortune.com. Legacy reference site with Wilhelm AND Legge translations, ~130 pages. Dated UX, but authoritative on the underlying text. Best as a secondary lookup, not a primary tool.
Honest disclosure
We built vaken. This page does try to sell you on it. We also recommended three competitors above in the situations where they beat us, because if you pick the wrong tool for your practice you will not get value from any of them. The I Ching has been around for 3,000 years — it can handle a little honest market competition.
Decide by casting, not by reading
Try vaken with a real question.
Three readings free every day. No account needed for your first one. If it doesn't fit your practice, the comparison table above has four other options.
