Frequently asked questions

Metaphysics tools often fail in the same places: the chart is wrong, the reading cannot be checked, and you do not know where your data went.

• Charts stay accurate: natal charts (BaZi, Zi Wei, astrology) are computed by a local deterministic engine; Tarot and Liu Yao use real draws, so the model never invents a chart.
• Readings can be checked: profile cards keep inputs consistent; if birth time is unclear, verification comes before any conclusion; complex questions become a visible task list you can follow.
• Data stays on your device: charts, profiles, and conversations live under .mystilink/ by default, with no full-library cloud sync.

GPTs and general-purpose agents can write readings, but they struggle with charting and workflow.

• They have no deterministic chart engine, so stems, stars, or hexagrams get invented.
• They rarely remember your profile the same way twice.
• There is no verification step or traceable task flow, and conversations usually stay in the cloud.

You can still bring your own key (BYOK) and use your preferred model for reasoning and writing. Mystilink keeps the chart engine and the workflow.

Free sites usually make money from ads and lead generation, and that shows up in the product.

• Conclusions tend to be templates that are hard to follow up or cross-check.
• Birth data you enter may be retained or used for profiling.
• Coverage is often a single system, with charting and interpretation split apart, and no way to plug in your own model.

Mystilink covers multiple systems with local deterministic charting, verification dialogue, and on-device data.

Metaphysics tools are used for a long time and kept private, so a subscription is a poor fit.

• Stop paying and you lose access and history.
• Local charting has almost no ongoing server cost, so a device license makes sense.
• The metered cost is LLM inference: pay with a Newton prepaid balance or your own API key (BYOK).

License and usage are separate: you pay for what you use. The purchase covers the current major version (1.x); major-version upgrades may be priced separately.
