What’s in the compatibility report
Six sections in a personalized digital report (PDF), written with AI from your two charts.
01
You and them
The overall feel of the connection: both Sun and Moon signs, how your strongest elements meet, and the contacts that set the tone.
02
Feelings and care
Both Moons and any contacts to them: what each of you needs to feel safe, and how you comfort each other.
03
Affection and attraction
Venus and Mars in both charts: how each of you shows affection, what draws you together and where your styles differ.
04
Talking and deciding together
Both Mercury signs: how you talk, disagree and decide as a pair.
05
Where you stretch each other
The squares and oppositions between your charts: where you rub, and what each of you can learn from it.
06
Standout connections
The three or four tightest, most personal contacts between your charts, with a short paragraph on each.
Rising signs and house overlays are included only when both birth times are known.
From a sample report for a fictional couple
Your Venus in Taurus in your 11th house shows affection through steadiness and presence. Think of the friend-turned-closer person who remembers how you take your coffee, shows up with the thing you mentioned once, and likes being together without needing a production. With Mars in Aries in your 11th house, the pursuit side is more direct than the Taurus softness suggests: you may find yourself making the first move, then settling into a slower, warmer rhythm once you're close.
Theo's Venus in Leo in your 3rd house, and in their own 5th house, leans toward warmth that wants to be seen. Compliments, planned dates, playful teasing and a bit of showmanship come naturally to them. Their Mars in Gemini in their 1st house adds a light, quick, curious energy to attraction, so flirting may run on conversation, jokes and trading ideas. Your Taurus patience and their Leo generosity can meet well, though your Venus is slower to warm than their Venus is to shine.

Questions
- Is it a prediction?
- No. A compatibility report describes styles and dynamics: how each of you tends to feel, show affection and make decisions, and where your charts fit or rub. It never says whether a relationship will last or end. For entertainment and self-reflection.
- What is synastry?
- Synastry is the astrology word for comparing two birth charts. We lay one chart over the other and look at where the planets sit at friendly or tense angles, and how each person’s elements balance.
- What do I need to enter?
- Each person’s birth date and birthplace, and the birth time if you know it. First names are optional. Both charts are drawn in your browser, so nothing is sent to us for the free preview.
- What if I don’t know a birth time?
- Tick the box and carry on. Without a birth time there is no rising sign or houses, and the free preview leaves out Moon contacts, since the Moon moves about 13 degrees a day. Everything else still works.
- Will the other person see my birth details?
- Not unless you tell them. With “Compare with someone”, each of you sees only the other’s first name and how your sun, moon, Venus and Mars connect. Neither of you sees the other’s birth date, time or place. If you enter someone’s details yourself, please make sure they’re happy for you to.
- Who writes the report?
- An AI writes it from your two charts, which we compute in code. No human astrologer writes or reviews it.
- What does it cost, and how fast is it?
- The free preview costs nothing and needs no email. The compatibility report is $19, or $49 inside Everything, which also has your full birth chart report and Your 2027. One-off price. No subscription. It is ready in about 2 minutes, and we email you the link.
- Can I get a refund?
- Yes. Full refund within 14 days, no questions. See the refund policy.
