The read shows the bridge. Your blueprint shows your end of it.

A compatibility read is shared ground. Your full blueprint is personal — your Spouse Palace in Zi Wei Dou Shu, your Peach Blossom timing in Ba Zi, your 7th house in Western astrology — and The Architect, an AI that knows your chart, to talk it through.

How we compute this

◆ Nothing hidden, nothing tuned to flatter

Step 01

Two charts, independently

Both charts are computed independently, with the same engines behind the full KAXANTA blueprint — real planetary positions, real pillars.

chart(A) · chart(B)
astronomy-engine + lunar-javascript

Step 02

Cross-chart geometry

Aspects between A's and B's planets, relations between the zodiac years, the generating and controlling cycle between day masters, life-path pairing.

aspects(A×B) · branches(Yᴀ,Yʙ)
cycle(DMᴀ,DMʙ) · pair(LPᴀ,LPʙ)

Step 03

A documented rubric

Each lens is scored on a documented rubric — harmony, friction, neutral. Every finding lands in one of the three, and the tallies are what you see on the cards.

finding → +harmony / −friction / 0 neutral

Step 04

Weighted, in the open

The composite is a weighted average of the four lenses. Weights are fixed per lens, published here, and never tuned to flatter a pairing.

0.35 × 57 + 0.20 × 85 + 0.25 × 55 + 0.20 × 82
= 67.1 → 67

Questions, answered straight

◆ FAQ

Do I need exact birth times?

No. Birth dates alone compute the zodiac pairing, day masters, life paths, and planet-to-planet aspects. Adding time and city sharpens the Moon and unlocks rising-sign overlays.

Is one score really meaningful?

The number is a weighted summary of four independent computations. The breakdown matters more than the headline — which is why we show the method.

Which systems count toward the score?

Western synastry, Chinese zodiac year relations, Ba Zi day-master elements, and numerology life paths. Human Design and Zi Wei Dou Shu need exact birth times, so they live in the full blueprint instead.

Can a low score doom a relationship?

No. Charts describe dynamics, not destinies. This is structural insight — people decide what to do with it.

Is our data stored?

No account, no storage. The reading is computed on request and isn't saved to any profile.

One bridge, read honestly. Nine systems on your side of it.
