Astrology that gets to know you
Who you are, in plain words.
My Sign reads your birth chart and tells you about you: how you love, what sets you off, and why you’re the way you are. Every morning it tells you what today might stir up. And it remembers what you share, so it knows you better every week.

How are you, really?
Your chart, read as a person
What you’ll read about yourself.
Not a list of planets. Your reading is written about you: how you love, how you argue, what you need and what people get wrong. Each line names the part of your chart it comes from, so you can see why.
In love
You test people before you trust them, and call it getting to know them. Once you’re in, you’re loyal in small, specific ways, like remembering their coffee order.
From your Venus and your Moon
Your toxic trait
You say “I’m fine” with the full confidence of someone who is keeping a ledger.
From your Sun and Moon, sitting together
When you’re mad
You go cold and very polite. No shouting, just shorter texts. If you do speak, it’s one sentence, and it’s the one that lands.
From your Moon and your Mars
What people get wrong about you
They think you’re unbothered. You’re feeling everything at full volume and running it through a filter first.
From your Moon and your rising sign
Examples from one real chart. Yours is written from the exact moment and place you were born.
How it works
It gets to know you, a day at a time.
A horoscope is written for a twelfth of the world. My Sign starts with who you are, then adds how you’re feeling and what’s going on in your life.
Day one
Meet yourself
Your chart, read as a person: your strengths, your blind spots, how you love and what you actually need. Most people find something they’ve never put into words.
07:30
A note about your day
What today might stir up for you, and why, in a sentence or two. Some days are quiet, and it tells you that too.
07:31
Say how you are
Rate your day from one to ten and add a line if you want. It takes fifteen seconds, and it’s how My Sign learns what’s true for you rather than for your sign.
Any time
Ask the real question
Should you text him? Is this the week for the talk with your boss? You get a clear answer, a reason and a good time — from something that already knows how your morning went.
Over time
It remembers
It keeps what you share, so it asks how the interview went and knows who Sam is three weeks later. Over a few months, it starts to see your patterns.
The science, if you want it
Personal, and still precise.
Everything it tells you about yourself starts from the real sky: where every planet actually was the moment you were born, and where they are today. Those positions are checked against NASA’s own data.
It never makes up a planet. The sky is calculated first, and the words about you are written from it, so there’s always a real reason behind what you read. That’s also how it can tell you, plainly, when Mercury isn’t retrograde.

The most any planet in your chart may differ from NASA’s own numbers. That’s less than the width of a coin seen from two miles away.

Your people
The people in your life, under the same sky.
Add a partner, a sister, the friend you can’t quite read. Each day you see who’s easy to be around, and why.
- Invite them with a link. They make their own chart from their own birth details, and say yes before anything is shared.
- Share how you feel, not what you write. Linked friends see each other’s daily mood score from one to ten — never the words — and only while sharing is switched on.
- No invented rankings. When two people are only a few points apart, it calls them even, because the difference isn’t meaningful.
Your people todayExample
- Sam72You’re easy company for each other today. Make the plan.
- Theo53Even with Jules — too close to call, so no ranking.
- Jules51Things run hotter than usual today, so keep it short.
Memory
Your patterns, not your sign’s.
Over weeks of check-ins, it notices what’s true for you: when you tend to feel low, which days lift you, what keeps coming back. It only tells you a pattern when your own days show it, never because “Scorpios are like that.”
The AI can suggest a pattern, but your own check-ins have to prove it before you hear it. That takes about three months. Until then, it tells you it doesn’t know yet.
Suggested · day 30Example
You feel worse around the full moon.
✕ Not shown to you. Four full moons aren’t enough to tell a pattern from luck.
Checked · day 120Example
The day after the Moon crosses your Saturn, your mornings tend to feel low.
✓ Shown to you — it held up against your own history.

What you tell it stays yours.

Questions
Fair questions.
Is it free?
Yes, to start. The free plan has the morning note, the daily check-in, your full chart, three messages a day and your first five people.
Plus — $9.99 a month, or $59.99 a year — is for when you want more: unlimited conversation and everyone in your People. You’ll see the full list before you pay a cent.
Do I need my birth time?
No. Without it, the signs your planets are in, and the angles between them (aspects), are still accurate. What can’t be known is your rising sign and your houses — the rising sign moves through the whole zodiac in a day.
So My Sign leaves those out rather than guess, and tells you so. Add your birth time later in Settings and your chart becomes exactly what it would have been from day one.
Is this a horoscope?
No. A horoscope is written for everyone born in the same month. My Sign reads today’s actual sky against your chart, and against what you’ve told it about your life.
It doesn’t predict events. It names what’s happening overhead and why it might feel the way it does — and on quiet days, it says it’s a quiet day.
Am I talking to a person?
No — the conversation is with an AI, and it says so. The astronomy is computed, not generated: the AI is handed the real sky and your history, and writes the words from them.
It isn’t a therapist or a crisis service. If a message suggests someone may be in danger, it gives you a crisis line straight away.
Is it on the App Store?
The iPhone app is coming soon. The web app works today: open it in Safari, tap Share, then Add to Home Screen. It opens like an app, and the 7:30 note arrives as a notification.
What happens to my data?
It’s used to run My Sign for you, and for nothing else: no advertising, no selling, no profile for anyone else. Conversations are processed by Anthropic to write replies, under terms that keep them out of model training.
You can delete everything from Settings at any time, and it’s gone from our database immediately. The privacy policy lists every place your data goes and how long it stays.
Tomorrow, 7:30.
Make your chart tonight and read about yourself in a minute. Your first note will be waiting in the morning.
