HOW IT WORKS
01

Save a local profile

Enter birth details and choose a tradition. Offline city data supplies time-zone and coordinate information.

02

Calculate with precision

Account for true solar time, historical daylight saving rules, and tradition-specific calculation settings.

03

Bring expert context to AI

Package chart data, terminology, method, and interpretive guardrails for the AI tool you already trust.

EXPERT CONTEXT FOR AI

Give AI more than a birth date.

FateKit turns calculated chart data, professional terminology, interpretive method, and clear boundaries into a structured prompt. You decide when—and where—to share it.

  1. 01
    Calculated chart dataUse on-device results instead of asking AI to rebuild the chart
  2. 02
    A professional frameworkDefine the order for planets, houses, aspects, and tradition-specific methods
  3. 03
    Clear interpretive limitsExplain terms, acknowledge uncertainty, and avoid fatalistic answers

PRIVACY FIRST

Personal by nature.
Private by design.

No account. No app server. No ads or analytics SDKs.
Your profiles, charts, and prompts stay on your device.

  • Works entirely offline

    Chart calculations run locally without a network connection.

  • Nothing is uploaded

    Your birth details and saved profiles never reach us.

  • No built-in AI connection

    FateKit creates text locally and never calls an AI model API.

  • You control deletion

    Delete profiles at any time; uninstalling removes the local app container.
