This page compares Sun, Mercury, Venus and Mars, the four placements a birth date alone can place. Moon, Ascendant and Midheaven are left out here by design, not by omission, so nothing on this page is scored against a birth time it cannot trust.

Where the two charts actually touch
The overlap
Two charts, laid over each other
Austin Butler and Kaia Gerber's Sun, Mercury, Venus, Mars and Moon are drawn here, along with the house ring and ascendant axis both charts support. This is a complete chart of what is known, not a partial chart of what is not.

Why they click
Every aspect in this pairing runs to the same point: one Mars, met by the other chart's Sun, Mercury and Venus, all by trine. That is a narrow but consistent signal. Identity, thinking and affection all reach the same drive at an easy angle, so the attraction reads as uncomplicated and physically led rather than intellectually entangled. Trines ask nothing of a couple, which is both the appeal and the limit.
Why they clash
Every category sits at the floor of the scale, and that is the honest headline. Three aspects is very little contact between two charts, and all three land on a single planet. There is no Sun to Sun, no Venus to Venus, no Mercury exchange at all. Neither chart reaches the other's core identity or values, so this is less a difficult pairing than a thin one. Both birth times are estimates, so the angles and houses are unavailable, which limits how much more the engine can say.
What each system says
Twelve systems, two people
The Suns are 16.5° apart, outside orb of any aspect, which is why identity reads as an empty channel above.
Goat and Snake are in neither the trines nor the clashes.
Guna Milan: 27.5 of 36
A second tradition
Guna Milan (Ashtakoot)
Guna Milan is the compatibility method used in Vedic matchmaking, traditionally consulted before an arranged marriage. It scores eight factors between two Moon placements on a 36-point scale, shown here as what this one tradition reads: not a verdict, and not averaged with the Western reading above, which may disagree.
27.5 of 36 points
Two things stated plainly rather than left silent: Varna and Vashya use a directional rule from traditional bride/groom roles, applied here in the order the two people are listed on this page rather than assigning either role. Bhakoot dosha's most common cancellation, matching rashi lords, is applied; Nadi dosha carries no cancellation here, though same-nakshatra-different-pada is sometimes cited elsewhere as easing it. Mangal (Kuja) dosha is a separate check and isn't part of this reading.

Read the relationship as one chart
This page compares Sun, Mercury, Venus and Mars, because those are the four that a birth date alone can place. With no hard contact between the two, a composite chart, the midpoint of both, often reads clean.
