169 astrological, psychological, and somatic traditions computed from a single birth chart. Every interpretive claim is cited to a primary text we hold. Every output traces back to the ephemeris. Where we have no source, we say nothing.

93 traditional D0–D2 systems converge at cosine 0.515–0.523 across 500 charts (511 comparable pairs), engine hypotheses excluded. Engine 2.7.0. Verified 2026-09-08.
Stars Engine takes a date, time, and place of birth and computes a 224-key master profile: planetary positions from the NASA JPL DE440 ephemeris, then 169 traditions derived from those positions — Western and Vedic astrology, BaZi, Human Design, Gene Keys, the humors, polyvagal mapping, ceremonial correspondences, and more. It does not tell you what your chart means. It computes what the traditions say, cites where each statement comes from, and shows where independent systems agree.
Stars is the product — not a demo for anything else. It is invite-only while the provenance layer is completed in the open.
The differentiator is not the tradition count. It is that we are willing to show our work, and to say when we cannot.
Every interpretive claim carries a citation to a held primary text — Agrippa for ceremonial, Parashara for Vedic, Ptolemy for Western. Where we hold no source, we say nothing. 113 of 183 claims are warranted today; the rest are marked unwarranted, not dressed up.
We never collapse corroboration to one number. Measurement independence asks how many distinct observables agree; transmission independence asks how many uninfluenced lineages arrived there. Ten systems reading one ecliptic longitude are one measurement, not ten — and we render both axes.
Findings are provenance-audited before they ship. The convergence claim was narrowed from an early over-broad figure to 93 traditional D0–D2 systems at cosine 0.515–0.523 once engine hypotheses were excluded. The correction is on the record.

The full methodology, including the two-axis independence model →
One engine, read through the vocabulary of the practice you already work in.
One chart across Western, Vedic, Hellenistic, and the Chinese pillar systems — with cross-tradition convergence and a citation on every claim.
For Western, Vedic & world chart astrologers →Goetic and Shem spirits, planetary hours, correspondences, and ritual timing — computed from the chart against the grimoire tables, each entry sourced.
For ceremonial magicians & esotericists →Compatibility across 18 synastry systems — karmic alignment, house overlays, attachment dynamics — with the two-axis independence model behind every score.
For couples coaches, matchmakers, dating products →Bring your client's assessment results — validated instruments and the quiz batteries. Stars synthesises them into one cross-referenced profile, cited to psychology literature only. No birth chart.
For counselors, coaches, somatic & bodywork practitioners →Birth cards, hexagrams, odu, runes, and numerology drawn from the chart — we compute the draw, the reading stays yours.
For tarot, I-Ching, Ifá & rune readers, numerologists →Turn a chart into a character with a spine, a mundane chart into a history, and transits into campaign arcs — with the planet of origin as a knob.
For game developers, novelists, TTRPG & D&D game masters →A documented REST API and an MCP server for charts, synastry, spirits, and cross-tradition graph traversal. Free tier, no credit card.
For API / SDK / MCP consumers →The convergence dataset, raw cosine scores, and Gold analytics — every claim scoped, sourced, and falsifiable, with the corrections on the record.
For academics, statisticians, skeptics, labs →Stars computes positions and derives systems. The reading belongs to the practitioner — in their tradition, with their training. We cite your authorities, not ours: Parashara for Vedic, Ptolemy for Western, Agrippa for ceremonial, the I Ching for Chinese divination. The wisdom stays with the living lineages; we just do the arithmetic and keep the receipts.
