Technique coverage

What the engine actually weighs.

  • Essential dignities

    Rulership, exaltation, triplicity, term, face — scored per the tradition.

  • Receptions

    Mutual, one-sided, and by lesser dignities. Direction matters.

  • Lilly moiety orbs

    Orbs belong to the bodies, not the aspects. Applying and separating resolved to the minute.

  • Translation & collection

    Detected automatically, reported as distinct perfection paths.

  • Antiscia & contra-antiscia

    Shadow aspects across the solstitial axis. Can serve as perfection when no direct aspect exists.

  • Arabic parts

    Full lot corpus computed on every chart — Fortune, Spirit, Marriage, Eros, Love, Children and more. Part of Fortune contributes testimony to the judgment.

  • Fixed stars

    Regulus, Spica, Algol and others — conjunctions with significators or angles are weighed by nature and magnitude.

  • Five house systems

    Regiomontanus by default — Lilly's choice — plus Placidus, Alcabitius, Porphyry, and Whole Sign.

  • Denial checks

    Prohibition, refranation, frustration, Moon void-of-course — applied before any verdict of "yes."

Questions

For the practitioner.

What orb system do you use?
Lilly moiety. Orbs belong to the bodies, not the aspects; applying and separating are computed to the minute.
Which house systems are available?
Regiomontanus is the default, as the tradition prescribes for horary. Placidus, Alcabitius, Porphyry, and Whole Sign are one click away. More can be added on request — the ephemeris supports them.
How is the verdict derived?
From perfection paths only: same-ruler, applying aspects within orb, co-presence in the same sign, translation, and collection. Dignities, speed, and reception inform the verdict's certainty but do not cause it.
Is this a replacement for my own judgment?
No. It is a rigorous second opinion. Disagreeing with the engine is expected and sometimes correct.
What ephemeris do you use?
Swiss Ephemeris. Positions are verified to the arcsecond.
Is it really free?
Yes — free while we're in early access. Pricing will come later as one-time credit packs, never a subscription. Chart casting stays free regardless.
Can I export a chart?
Planned. Use the contact form if you need it sooner.
