Danu, what is most active in my chart right now, and who in my Circle could use a check-in this week? Name the transits behind the reading and help me draft one thoughtful message.
Then ask: “What is a good question to ask them, without assuming how they feel?”
Someone new
Bring someone into the picture.
Add someone whose details you know, or create a compare link so they can enter their own.
Connected Danu account
You send the link. They choose whether to share their details and join your Circle.
Danu, help me add someone to my Circle. Ask for their name, our relationship and the birth details I know. Confirm the details before saving. If I don’t know their birth date or birthplace, help me create a compare link instead.
Then ask: “If we created a compare link, give me a short message I can send with it.”
The group chat
Share the roles. Keep birth details off the card.
Create a Circle card with first names, roles and a short group summary.
Connected Danu account
Anyone with the link can view the card. Birth dates, birth times and birthplaces are not included.
Danu, make a share card of my Circle’s roles for our group chat. Show me the link and explain what people will be able to see.
Then ask: “How would you describe this group in one sentence?”
The astrology behind the conversation
Calculated charts, explained in conversation.
Danu calculates chart positions and contacts with the Swiss Ephemeris. In ChatGPT, those computed facts become the basis for the conversation. Ask which placement matters, add the situation you’re dealing with, and follow up on what you want to understand.
Follow up with “Which chart contacts are you drawing that from?” to keep the conversation connected to the astrology.
Explore Danu’s methodBefore you begin
A few useful details.
Do I need a Danu account?
You can compare two people without a Danu account. Connect an account to use your saved chart, explore your Circle, add people, create compare links and make Circle share cards. Complete your birth chart in Danu before using those linked features.
What if I don’t know a birth time?
Say that the time is unknown. Danu can still compare the available placements and contacts. She leaves the rising sign unavailable when the birth time is unknown. A birth date and birthplace are still needed for each person.
Does a quick comparison save people to my Circle?
No. A quick comparison does not add either person to a Danu Circle. To save someone there, connect your account and ask Danu to add them. Simply connecting your account does not save a comparison.
What happens to details I type into ChatGPT?
What you type is part of your ChatGPT conversation and is handled under ChatGPT’s settings and policies. A quick comparison does not save those people to a Danu Circle. People you choose to add to your Circle are saved in Danu. Circle share cards are public to anyone with their link, and omit birth dates, birth times and birthplaces.
I installed Danu. How do I make sure the chat uses her?
Start a new chat after installation. Type @, select Danu, then paste a prompt or ask your own question. If ChatGPT asks you to connect your Danu account for a Circle feature, finish the sign-in and approval steps, then try the question again.
For the details on what Danu stores and shares, read our privacy policy.
Start with someone you want to understand.
Two people. Two charts. A question worth asking.
