A Chrome extension · yì jīng 易經
The I Ching in your toolbar — an animated three-coin casting ritual, all sixty-four hexagrams with changing lines, and a private record of every consultation. Fully offline. No tracking. No account.
One permission only: local storage, for your own casting record.
a divination manual three thousand years old, done properly
Three bronze coins flip six times. Each throw draws one line of your hexagram onto the screen, from the bottom up — as the ritual prescribes. Tap to hurry the coins.
Old yin (6) and old yang (9) glow bronze, are read by their position — from the beginning to the culmination — and resolve into a second, transformed hexagram.
Switch between the three-coin probabilities and the classical yarrow-stalk odds, which weight the lines the way the traditional fifty-stalk ceremony does.
All 64 hexagrams in the King Wen sequence, with Chinese names, pinyin, trigram composition, and concise original readings of the Judgment and the Image.
Your last twenty consultations — hexagrams, transformations, and the questions you held in mind — kept on your device and nowhere else.
No network requests, no analytics, no accounts, no remote code. Everything runs offline inside the popup. Open the source and see for yourself.
