Use AI to compare two astrology charts

Choose the comparison before writing the prompt

The phrase astrology compatibility covers several methods that answer different questions. A Sun-sign comparison looks at one placement from each person. Synastry compares factors between two natal charts. A composite constructs a separate symbolic relationship chart, commonly using midpoints. Vedic kundli matching applies a different framework, including the Ashtakoot factors calculated from the two sidereal Moons.

Choose one method for the first conversation. Otherwise an assistant may move from a Western Venus placement to a Vedic matching score without explaining the change. You can compare traditions later, but give each calculation its own label and interpretation rather than adding their outputs into an invented total.

StarScore's Sun-sign pair guides and kundli matching calculator provide two concrete starting points. For synastry or a composite reading, obtain an output explicitly calculated for that method and supply it separately. Two individual placement tables are useful for comparison, but they do not themselves constitute a verified synastry aspect report.

Make two small, consistently labelled chart records

Use the birth chart calculator for each individual chart. Label the results Person A and Person B. Record the zodiac, house system and birth-time quality for each. If one time is unknown, keep that fact attached to every copied extract. Do not borrow the other person's certainty or fill in a plausible ascendant.

Start with only the placements needed for your question. For communication, you might include the supplied Mercury positions and calculated aspects involving them. For preferences around closeness, you might study the supplied Moon and Venus positions. These are interpretive starting points, not rules that those planets reveal everything about a person's relationships.

Ask about a situation both people can recognise

Replace "Are we compatible?" with a bounded topic such as planning shared time, discussing a disagreement or choosing how much structure a project needs. A concrete setting makes it easier to distinguish an interesting interpretation from an assumption about someone else's intentions. Both people can then say which descriptions fit and which do not.

For an explicitly hypothetical exercise, suppose one interpretation emphasises quick verbal processing and another emphasises taking time before responding. The useful discussion is how each person prefers to handle a pause in conversation. The chart does not establish that either person actually behaves this way; their answers provide that information.

Fill in a comparison worksheet

The connection row is especially important. If you have only two signs, label the exercise a sign-based comparison. If you have an exact aspect and orb, preserve those values. See the AI aspect-reading workflow for checking the difference between a calculated angle and an inferred theme.

A prompt for a balanced comparison

Compare Person A and Person B using the method and chart entries below. Our question is [shared situation]. First confirm which entries belong to each person. Make a table with source placements, a possible traditional interpretation, an alternative interpretation and a question both people can discuss. Use only supplied inter-chart aspects; label any sign-based comparison as such. Preserve birth-time uncertainty. Do not invent a compatibility percentage, infer private intentions or decide whether the relationship should continue.

Ask for equal space for both people, then review the source-placement column first. If the assistant reverses A and B, correct that before discussing meaning. If it introduces a composite placement into a synastry reading, return to the selected method. Clear labels keep the explanation useful as the conversation grows.

Read a matching score within its own rules

An Ashtakoot total belongs to its eight-factor system and maximum of 36 points. It is not a measured probability of a successful relationship. Ask the assistant to explain each supplied factor, its points and the convention behind it. Keep additional checks, such as a supplied Manglik result, distinct from the eight-factor total.

The AI kundli-matching guide develops that workflow. For a Western comparison, do not turn a count of easy and difficult aspects into a percentage either. The weighting would need an explicit method, and a tidy number still would not represent an established relationship outcome.

End with two questions, not a label

Let each person choose one question from the worksheet and answer it independently. Compare those answers before returning to the chart. Keep the parts that support a thoughtful conversation, and note where the symbolism did not fit. This leaves you with a useful record of the discussion rather than a permanent label attached to the relationship.
