Astra is an AI astrology companion for exploring your birth chart, relationships, and the periods that matter to you. Shaped by your birth details and the story you choose to share.
Request a demoAstra’s calculation engine uses Swiss Ephemeris to work out planetary positions, houses, and aspects from your birth details. AI uses those results to explain your chart and explore the questions you bring.
Ask about a particular month, and Astra can work with transits for that period. Share what is happening in your life, and that context helps shape the interpretation. The calculations supply the chart data; the conversation explores what you make of it.
Explore the patterns in your birth chart, from communication and relationships to how you approach change. Ask what a placement means, then go deeper into the parts that resonate.
What does my chart suggest about how I approach change?
Explore how planetary movements relate to your birth chart on a particular date or across a period. Look back at a turning point or consider the themes of the month ahead.
How do this month’s transits relate to my chart?
Bring two charts and the story of a relationship into the same conversation. Explore communication, shared tendencies, and points of tension in partnerships, friendships, family, or work.
How do we approach communication differently?
Work through an uncertain birth time with a guided conversation. Astra uses dated life events and follow-up questions to compare possible times and suggest one to explore further.
I was born sometime in the morning. Where do we start?
You can arrive with a specific question or simply be curious about your chart. Start wherever you are, and let the next question lead the way.
Add your date, time, and place of birth. Astra calculates your chart and saves it to a profile, ready for your next conversation.
Ask about something on your mind: a pattern in your chart, a relationship, or a period of change. Give as much background as you want.
Ask for a clearer explanation, challenge an interpretation, or explore a different angle. Each follow-up can focus on what you want to understand next.
Your birth time shapes parts of your chart, including your rising sign and houses. If yours is uncertain, Astra offers a guided process called birth-time rectification.
Start with a possible time window, or explore the full day. Share dated milestones such as a move, graduation, or career change. Astra compares candidate times against those events and asks follow-up questions to help distinguish them.
You receive an estimated birth time, alternatives, and an explanation of how your events informed the suggestion. You can use the suggested time as the basis for a new profile and continue exploring your chart.
The questions you bring to your chart can change with your life. A new role, a move, or a relationship can give your next reading a different starting point.
Astra can remember relevant details across conversations, so you can return to an ongoing topic without explaining the background each time. You decide how much of that context to bring into the conversation.
Create a profile for each person whose chart you want to explore. Birth details and saved context stay connected to the relevant profile.
Review what Astra remembers, correct a detail, or remove it. You can also turn personalization off for an individual profile.
Start a chat that adds nothing to long-term memory. Choose whether it uses your saved context, only your birth chart, or neither.
No. You can start with a question in your own words. Astra explains the relevant parts of your chart as you go, and you can ask it to unpack any unfamiliar term or explore a placement in more detail.
Yes. You can ask about past, current, or upcoming periods. Astra calculates transits for the dates you choose and explores how they relate to the selected birth chart.
