Know yourself. Think a decision through. Yi brings together self-discovery, classical-text study and a private decision-reflection journal. Start with a self-report questionnaire, a real question, a passage or a story. Or simply write down a decision and revisit it later. No knowledge of the I Ching is needed to record your thoughts, explore what matters to you and notice how your thinking changes. Your choices about work, relationships, family and learning remain your own. Yi does not predict outcomes or decide for you. READ THE CLASSIC • Browse and study all 64 hexagrams in Classics. • Each hexagram includes verbatim source text from the authoritative Zhonghua Book Company edition of the Zhouyi, a readable guide, and commentary from multiple classical schools with citations. REFLECT, DON'T PREDICT • Clarify a real question, read a reflective interpretation, and save your thoughts. • Review past entries to notice your own patterns. Yi supports reflection; it does not make decisions for you. PRIVATE BY DESIGN • AI assistance runs on your device by default. If on-device AI is unavailable, source texts and reflection steps remain available; your question is never sent to a cloud model automatically. Open the Iris tab, “Who am I?”, in the bottom bar. Yi personality brings together six I Ching dimensions, Big Five, values and your current state as separate self-reports, without a combined personality score. Basic assessments and sharing are free; portrait history and reflection across models remain included in Yi Plus. Results support reflection, not diagnosis. The separate Birth chart is a cultural reflection tool that can calculate and save positions on supported devices using your birth date, place and time. An unknown time produces a full-day range without a definite ascendant or houses. Devices that cannot calculate can still manage birth details. Birth details are excluded from sharing and AI context by default. • Optional sync between your devices is end-to-end encrypted. The service cannot read synced content. • Export or permanently delete your data at any time. FOR LEARNERS • Study in Simplified Chinese, Traditional Chinese, English, or Japanese. • Follow structured courses, source editions, long-form stories, and your own reading progress. AI AVAILABILITY On-device assistance is available on supported devices; source reading and reflection work independently. Overseas cloud assistance and AI-point purchases are not available in this version. Yi is for reflection and study only. Its content is not medical, legal, financial, or investment advice. SUBSCRIPTION (OPTIONAL) Yi is free to use, including the 64 hexagrams, source text, multi-school commentary, local journaling, basic sharing, and public study cards. Yi Plus adds structured courses, progress and study badges, full encrypted sync and restore, richer review schedules, on-device multilingual study support, and advanced share cards. Yi Master includes all Plus benefits plus the monthly Three-Mirror PDF, basic and collector annual reports, Master notes, the supporter badge, priority help and support, 30 Yi Credits each month, and collector visual packs. Subscriptions renew automatically and can be managed or cancelled in your Apple Account settings. Privacy Policy: https://cardmira.com/privacy Terms of Use: https://cardmira.com/terms
