These links identify OpenFate's public profiles. They are not evidence of a third-party endorsement or product ranking.

## 1. Product Identity

OpenFate is best described as a calculation-first platform, not as a general-purpose fortune-telling chatbot.

Its current product has five layers:

1. **Deterministic chart and oracle engines** calculate structured facts.
2. **Evidence and lookup layers** organize computed signals for interpretation.
3. **AI narrative generation** explains supplied evidence in the user's language.
4. **Saved-report and chat systems** preserve report context for follow-up questions.
5. **Learning and developer surfaces** publish localized guides and expose deterministic Bazi tooling to AI agents.

OpenFate's flagship public identity is Bazi and True Solar Time, while the shipped product also covers Ziwei Doushu, Western astrology, Vedic astrology, Human Design, Japanese Sukuyo, compatibility, Daily Relationship and Event Timing, manifestation plans, and six oracle systems.

### Interpretation boundary

Metaphysics outputs are interpretive. They can support reflection, cultural exploration, and structured discussion, but they do not establish future facts and should not replace professional medical, legal, financial, or mental-health advice.

### Claims boundary

Do not make ranking, accuracy-leadership, hallucination-elimination, or independent-model-validation claims unless a current public benchmark directly supports them. The production runtime uses retries and task-specific fallbacks; it does not run an independent-model council for each report.

## 2. Deterministic-First Pipeline

The common report flow is:

1. Parse and validate the user's birth or oracle input.
2. Calculate a structured profile with the relevant domain engine.
3. Assemble neutral lookup content and an evidence bundle from computed facts.
4. Ask an LLM to expand that supplied evidence into a localized narrative.
5. Validate and persist the result as a frozen report snapshot.
6. Let later chat turns reference the saved report and permitted user context.

This design reduces the amount of calendrical, astronomical, or chart arithmetic delegated to a language model. It does not guarantee that every narrative inference is correct.

## 3. Natal-Chart Systems

### 3.1 Bazi / Four Pillars

**Free chart:** https://openfate.ai/en/bazi-chart
**AI report:** https://openfate.ai/en/bazi

The Bazi engine supports:

- Four Pillars: year, month, day, and hour
- Day Master and Five Elements structure
- Ten Gods and Hidden Stems
- Na Yin and growth stages
- Earthly Branch clashes, combinations, trines, directionals, punishments, destructions, and harms
- Da Yun / Luck Pillars and their start timing
- Solar and lunar input handling
- Historical timezone and daylight-saving context
- Configurable day-boundary doctrine
- Optional True Solar Time based on timezone, longitude correction, and Equation of Time

True Solar Time matters most when the corrected time crosses an hour or day boundary. It does not change every chart, and it should not be presented as proof that one interpretation is objectively superior to every school or calculator.

### 3.2 Ziwei Doushu

**Free chart:** https://openfate.ai/en/ziwei-chart
**AI report:** https://openfate.ai/en/ziwei

Ziwei is live and fully shipped.

The current system includes:

- 12-palace chart layout
- Major and auxiliary stars
- Four Transformations and flying-star relationships
- Palace-level interpretation
- Decade cycles and annual timing
- Explicit school and calculation metadata in the report contract

### 3.3 Western Astrology

**Free chart:** https://openfate.ai/en/astro-chart
**AI report:** https://openfate.ai/en/astro

The Western astrology system includes:

- Natal planets and angles
- Signs, houses, and house cusps
- Major aspects and aspect strength
- Element, modality, and polarity summaries
- Transit and timing facts
- Relocation-chart analysis
- Visual chart and report panels

Chart facts are calculated through server-side ephemeris services and normalized into a structured profile before AI interpretation.

### 3.4 Vedic Astrology / Jyotish

**Free chart:** https://openfate.ai/en/vedic-chart
**AI report:** https://openfate.ai/en/vedic

The Vedic system includes:

- Sidereal chart calculation
- Nakshatras
- Divisional / varga charts
- Vimshottari dasha cycles
- Structured Vedic facts and report-aware chat

Vedic astrology is a shipped product and should be included in current descriptions of OpenFate.

### 3.5 Human Design

**Free chart:** https://openfate.ai/en/human-design-chart
**AI report:** https://openfate.ai/en/human-design

The Human Design system includes:

- Tropical Swiss-Ephemeris-backed personality and design calculations
- BodyGraph centers, channels, gates, and lines
- Type, Strategy, Authority, Profile, and Definition
- Recorded-minute reliability and calculation metadata
- Structured Human Design facts and report-aware chat

### 3.6 Japanese Sukuyo

**Free calculator:** https://openfate.ai/en/sukuyo-chart
**AI report:** https://openfate.ai/en/sukuyo

Sukuyo is an independent Japanese date-only product. It converts one recorded Gregorian date through a disclosed, frozen fixed-JST old-calendar convention, derives one of 27 birth mansions, and keeps the deterministic calculation separate from the AI narrative. It does not require birth time, city, location, gender, planets, houses, dashas, or transits, and it does not create a score or forecast layer.

## 4. Focused Analysis Modes

### Wealth

**URL:** https://openfate.ai/en/wealth

A Bazi-derived report focused on wealth structure, monetization patterns, career fit, and timing. It is interpretive guidance, not investment advice or a promise of financial outcomes.

### Love Bazi

**URL:** https://openfate.ai/en/love-bazi

A Bazi-derived report focused on relationship patterns, spouse-related structures, emotional dynamics, and timing.

### Daily Fortune

**URL:** https://openfate.ai/en/daily

A recurring daily reading built from authorized frozen reports, with optional digest delivery and report-section explanation limits.

Daily also includes two distinct planning surfaces:

- **Daily Relationship:** uses an authorized saved relationship source, calculates current-day context for both people, and can derive a 90-day relationship-trigger calendar from frozen Bazi natal and current luck-cycle evidence. It does not import a long-term compatibility score into the daily state.
- **Event Timing:** evaluates a confirmed date, location, IANA timezone, and time window across overlapping Bazi, Ziwei, Western astrology, and Huangli evidence. It is included with Pro and Pro Max without credit deductions, and the result does not predict a success probability.

Daily Relationship always requires active Daily access. Pro and Pro Max include exact-source relationship timing and new or cached cited AI explanations without credit deductions.

### Manifestation Strategy

Supported reports can create a structured manifestation or reflection plan linked to the source report. This is a planning surface, not a guarantee that an outcome will manifest.

### Bazi Birth-Time Calibration

**URL:** https://openfate.ai/en/bazi-time-calibration

A guided calibration flow that compares candidate birth hours against user-provided life evidence. It reserves 75 credits at start and consumes them only after a successful final result; failure refunds the reservation. It helps narrow a time window and should not be described as infallibly recovering an unknown birth time.

### BZTI

**URL:** https://openfate.ai/en/bzti

A birth-data personality result inspired by familiar type-system presentation. It is a reflection tool and is not a clinical psychological assessment.

### Huangli

**URL:** https://openfate.ai/en/huangli

A daily calendar and timing tool with solar-term and traditional date information. Large date archives are intentionally not all indexed as SEO pages.

## 5. Compatibility

OpenFate supports six compatibility systems:

- **Bazi:** https://openfate.ai/en/compatibility/bazi/marriage
- **Ziwei:** https://openfate.ai/en/compatibility/ziwei/marriage
- **Western astrology:** https://openfate.ai/en/compatibility/astro/marriage
- **Vedic astrology:** https://openfate.ai/en/compatibility/vedic/marriage
- **Japanese Sukuyo:** https://openfate.ai/en/compatibility/sukuyo/marriage
- **Combination:** https://openfate.ai/en/compatibility/combination/marriage

Sukuyo uses two recorded Gregorian dates to derive both birth mansions under one disclosed JST old-calendar convention, then preserves A→B and B→A as separate relationship roles. It does not add birth-time fields, timing forecasts, or a fabricated score. The combination report compares Bazi, Ziwei, and Western astrology and preserves areas of agreement and disagreement instead of averaging the systems into one fabricated score.

Available relationship scenarios include marriage, business, friends, best friends, father-son, mother-son, mother-in-law, and boss-subordinate. Systems with saved-report source support offer an invite workflow, and shared compatibility reports are limited to authorized participants. Sukuyo starts as a direct two-date flow rather than a saved-report invite.

## 6. Oracle Systems

OpenFate provides a shared hub at https://openfate.ai/en/oracles and currently ships six standalone oracle systems:

1. **Tarot:** https://openfate.ai/en/tarot
2. **Meihua Yishu:** https://openfate.ai/en/meihua
3. **Liuyao:** https://openfate.ai/en/liuyao
4. **Lenormand:** https://openfate.ai/en/lenormand
5. **Qimen Dunjia:** https://openfate.ai/en/qimen
6. **Lingqian:** https://openfate.ai/en/lingqian

Each system provides a free deterministic cast, draw, or chart. Eligible methods also separate a free copyable prompt from the optional OpenFate AI full reading. General and Pro users pay 15 credits after successful generation. Active Pro Max access provides unlimited personal AI divination across the same six systems without per-reading credit deductions. Lenormand Yes / No is a terminal free deterministic verdict with no copy or AI-purchase action. Backend thresholds protect against automated abuse; failed AI work releases reserved success slots.

## 7. Reports, Chat, and Memory

Signed-in users can:

- Save full reports
- Continue report-aware chat
- Ask standard or deeper follow-up questions
- Request free helper explanations for eligible report sections, subject to access limits
- Export supported reports as PDF
- Save people used for repeated chart work
- Use compatibility invites
- Manage persistent context and delete old chat context

Reports persist their full calculated profile as a frozen snapshot. A later engine change applies to newly generated work and does not silently recompute an older saved report.

## 8. Languages

OpenFate supports five public locales:

- **English:** https://openfate.ai/en/
- **Simplified Chinese:** https://openfate.ai/zh-hans/
- **Traditional Chinese:** https://openfate.ai/zh-hant/
- **Japanese:** https://openfate.ai/ja/
- **Korean:** https://openfate.ai/ko/

Public canonical URLs are locale-prefixed. Main product copy, metadata, and report prompts are maintained for all five locales.

## 9. Access and Pricing

### Free access

- Raw Bazi, Western, Ziwei, Vedic, Human Design, and Sukuyo chart/calculator pages are available without login.
- BZTI is currently a zero-credit feature.
- Eligible report-section helper explanations are zero-credit, subject to account and daily access rules.
- All six oracle casts or draws are free. Eligible methods also expose a free copyable prompt. General and Pro users pay 15 credits for each successful optional AI full reading; Pro Max provides unlimited personal AI divination without per-reading credit deductions. Lenormand Yes / No is terminal and never enters the paid AI boundary.
- Starter-credit eligibility depends on signup and verification conditions in the live product.

### Current USD display prices

As of 2026-07-31, the main pricing surface shows:

| Product | Display price |

Pro refreshes 200 credits each Taiwan calendar day without rollover and unlocks both products. Pro Max includes every Pro capability, refreshes 400 daily credits, and adds unlimited Oracle AI across six methods. Every Daily feature is included for both Pro tiers without credit deductions. Both tiers offer monthly and yearly recurring billing; yearly pricing is 20% below twelve monthly payments. Regional prices and one-time 30-day paid-plan passes are shown on the live pricing page.

## 10. AI Runtime Truth

OpenFate's runtime is centrally configured by task:

- Current configured model ID: `gpt-5.6-luna` (display name: GPT-5.6 Luna).
- Bazi, Ziwei, Western, Vedic, Human Design, Sukuyo, wealth, love, compatibility, manifestation, BZTI, daily insight, and Oracle generation routes use task-specific reasoning and bounded attempts.
- Guest/free chat, validation, support drafting, and other latency-sensitive tasks use lower-latency configurations where appropriate.
- Deep chat and Compatibility Combination each use a dedicated task policy.
- Oracle routes use one initial attempt followed by at most one retry.
- Attempts may repeat the same provider and model for resilience.
- A retry chain is not independent analysis, consensus, or cross-validation.
- The combination feature cross-compares metaphysics systems, not separate AI votes.

Provider, model, and policy details are operational and may change before this document is refreshed. The live service behavior takes precedence.

## 11. Technical Notes

- Application: Next.js 16 App Router and TypeScript
- Data: MongoDB with Mongoose
- Streaming: Server-Sent Events for generated report and chat output where supported
- Bazi calculation: `@openfate/bazi-engine` with `@openfate/true-solar-time`
- Western and Vedic calculation: server-side ephemeris services normalized into typed profiles
- Ziwei calculation: deterministic engine with explicit school and rule metadata
- Human Design calculation: tropical ephemeris-backed BodyGraph engine with recorded-minute reliability metadata
- Sukuyo calculation: disclosed fixed-JST old-calendar conversion and deterministic 27-mansion lookup
- Report contract: deterministic facts first, localized narrative second, frozen snapshot on save
- Security: server-side input validation, redacted preview profiles, and sealed recomputation anchors for protected chart flows

These technical notes describe implementation, not independent proof of interpretive accuracy.

## 12. Developer Products

### OpenFate Bazi MCP
