People love asking chatbots about astrology, and honestly, the conversations can be great. Here are twenty prompts that get the most out of any AI — followed by the one problem no prompt engineering can solve.
A chatbot does not compute your chart
A language model produces the next plausible piece of text — that is the whole mechanism. It is good enough that "your Moon is in Scorpio" arrives in the same confident register whether it was computed or invented.
Casting a chart is different work: an ephemeris good to arc-minutes, the historical timezone rules for your birthplace, and spherical trigonometry to turn one moment at one latitude into house cusps and an Ascendant. Miss the timezone by an hour and the Ascendant lands in a different sign, reshuffling every house.
So: ask a chatbot to find your placements and it fails, fluently. Supply them and ask it to interpret, and it does well — that is language work. Cast your chart somewhere that does the math, then paste every planet with sign, degree and house, plus Ascendant, Midheaven, aspects with orbs, and house system. Say so if your birth time is uncertain.
The twenty prompts
For self-understanding:
- "My Sun is [sign], Moon [sign], rising [sign]. What tension between these three would people close to me notice first?"
- "Explain my [placement] the way a kind but blunt friend would."
- "What does my chart suggest I over-rely on when I'm stressed?"
- "Which of my placements most contradicts how I usually describe myself?"
- "Read my Big 3 as one personality system, not three separate paragraphs."
For relationships: 6. "My Venus is [sign], theirs is [sign]. Where do our definitions of affection differ?" 7. "What would a hard week look like for a couple with my Moon and their Mars?" 8. "Which of my needs am I least likely to say out loud, given my Moon?"
For work: 9. "Given Saturn in my [house], what kind of discipline actually sticks for me?" 10. "What work environment would exhaust my chart fastest?"
For learning astrology itself: 11. "Explain houses using a theater metaphor." 12. "What's the difference between a square and an opposition, emotionally?" 13. "Why do astrologers care about retrogrades? Steelman it, then critique it." 14. "Teach me aspects using two coworkers as an example." 15. "What's the strongest skeptical argument against astrology, and what do thoughtful astrologers say back?"
For fun: 16. "Roast my Big 3, gently." 17. "Write my chart's dating profile." 18. "Which fictional character shares my chart's core tension?" 19. "My chart plans a dinner party. What goes wrong?" 20. "Give my Saturn return a film-trailer voiceover."
Eight longer prompts you can paste
Those twenty are conversation starters. These are the full versions, each with its failure mode.
1. Whole chart, one system
Computed natal chart below, from an ephemeris. Treat it as given.
[ten bodies: sign, degree, house. Ascendant. Midheaven. House system.]
Read it as one personality system, not ten paragraphs: the two or three
strongest themes, which placements produce each, and where the chart argues
with itself.Without the numbers: it invents a chart shaped like your birthday and reads that one.
2. One placement in depth
Placement: [planet] at [degree] [sign], [house], [house system].
Aspects it makes: [list with orbs].
Go deep on this one: the planet's nature, what the sign does to it, what the
house gives it to work on, how the aspects change the picture. Where the
traditional and psychological readings disagree, say so.Without the numbers: it picks whichever house sounds right for the sign — Mars in Aries "in the 1st" — and builds on that.
3. One aspect, with its orb
Natal aspect: [planet A] [degree sign] [aspect] [planet B] [degree sign],
orb [x]°, [applying/separating].
What does this describe in the tradition, what does it feel like from the
inside during an ordinary week, and how do people with it misread themselves?
Take the orb seriously: loud or quiet at this distance?Without the numbers: orbs are what a model fabricates most readily. A nine-degree "conjunction" is not one.
4. Synastry between two charts
Chart A: [full placements]
Chart B: [full placements]
Cross-aspects: [list with orbs]
Where do the needs line up, where do they collide, and which collision is
workable versus a genuine structural difference? No compatibility score, no
verdict on whether we should be together.Without the numbers: two guessed charts, so the comparison is about two people who do not exist.
5. A transit, supplied
Natal: [relevant placements with degrees].
Transit: [planet] at [degree sign], [applying to / exact on / separating
from] my natal [placement], orb [x]°.
What does this transit traditionally describe, what is it not a claim about,
and what is worth watching — as a question I could ask myself, not a
prediction.Without the numbers: the model does not know where Saturn is today. Sky positions are a lookup, not a memory.
6. Translate the jargon
Explain these terms as if I have never read an astrology book: [paste the
jargon]. For each, the plain meaning, why astrologers track it, and one
common misunderstanding.Without the numbers: fine as it stands. This one needs no chart, and neither do the learning prompts above — vocabulary and history are where a general chatbot is genuinely good.
7. Stress-test a reading
My computed chart: [paste].
An interpretation someone gave me: [paste].
Which claims follow from placements that are actually there, which are
generic enough to fit anyone, and which contradict the chart? Quote the
placement behind each verdict.Without the numbers: it checks the reading against a chart it also invented, then agrees with itself.
8. The placement you avoid
From the chart below, pick the placement I am most likely to explain away
when I describe myself, and say why. Then make the strongest sympathetic
case for it.
[paste chart]Without the numbers: it hands you a flattering placement you do not have.
What a filled-in prompt looks like
An example chart. Nobody real, but every figure below came out of this site's own engine for that birth moment, so you can check it against ours or anyone else's:
Born 3 March 1992, 07:40 GMT, Manchester, England (53°28'N, 2°15'W)
House system: whole sign
Sun 12°59' Pisces 12th
Moon 29°15' Aquarius 11th
Mercury 29°04' Pisces 12th
Venus 16°49' Aquarius 11th
Mars 10°51' Aquarius 11th
Jupiter 9°15' Virgo (R) 6th
Saturn 13°07' Aquarius 11th
Uranus 17°00' Capricorn 10th
Neptune 18°20' Capricorn 10th
Pluto 22°56' Scorpio (R) 8th
Ascendant 10°40' Aries
Midheaven 3°45' Capricorn
Aspects, with orbs
Uranus conjunct Neptune 1°20'
Mars conjunct Saturn 2°16'
Venus conjunct Saturn 3°42'
Sun opposite Jupiter 3°44'
Venus conjunct Mars 5°58'Forty minutes after sunrise puts the Sun in the 12th: above the horizon, still behind the Ascendant. Prompt three, filled in:
Natal aspect: Sun 12°59' Pisces opposite Jupiter 9°15' Virgo retrograde,
orb 3°44'. Same chart also has Mars 10°51' Aquarius conjunct Saturn 13°07'
Aquarius, orb 2°16'.
What does each of these describe in the tradition, what does it feel like from
the inside during an ordinary week, and how do people with them misread
themselves? Be specific about the Pisces-Virgo axis and about what Mars and
Saturn do to each other in Aquarius.The model was never asked to know anything about the sky. That was settled before the conversation started.
Prompts that do not work
"Will I get the promotion in October?" Astrology is a symbolic tradition, not a forecasting instrument, and nothing in it licenses that claim. A chatbot will still produce a sentence shaped like a forecast. The shape is not evidence.
"When exactly will it happen?" Dates need transit math you have not supplied, and even done correctly, the tradition's timing describes symbolic seasons, not appointments.
"Guess my rising sign from my personality." The most fun prompt here and the emptiest. Your Ascendant is a function of the clock and your latitude, nothing else. The model is reading your writing style and picking something complimentary.
"Does my chart show a health problem?" and "How long will I live?" Don't. A chart is not a medical opinion in any tradition worth taking seriously, and an invented chart is worse than none. Our own tool refuses these outright.
The problem no prompt can fix
Notice what every good prompt above has in common: you have to supply the placements yourself. Ask a general chatbot "what's in my chart" and it will guess — fluently, confidently, and often wrongly, because computing a chart requires ephemeris math, timezone history and spherical trigonometry that a language model does not perform reliably.
Garbage in, eloquent garbage out. If the placements are wrong, the world's best prompt produces a beautifully written reading of somebody else's chart.
That is the entire reason chart-first tools exist. Our reading computes your chart with real ephemeris math before the AI says a word — every placement it discusses is one you can verify on the wheel next to the text. Same conversational pleasure, but pointed at your actual sky. Use the twenty prompts above in the astrologer chat; it already knows your chart, so you can skip the part where you type your placements in by hand.
