A daily companion · astrology is the lens
The sky, read against your own life — and remembered.
Every morning, a note from your real transits. Fifteen seconds to say how you are. A conversation that knows what you told it last week.

How are you, really?
How it works
One small loop, every day.
Not a horoscope written for a twelfth of the world. A daily rhythm built around your chart, your mood and what’s actually going on.
07:30
A note from your real sky
Computed from today’s transits to your own chart, with the reason named so you can check it against your day. Quiet days are allowed to be quiet.
07:31
Fifteen seconds, honestly
How are you, one to ten, and a line if you want. It’s what makes the rest of the day about you rather than 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 position, a reason and a time — from something that already knows how your morning went.
Overnight
It remembers
What you shared is kept, so tomorrow’s note knows about today. Three weeks from now, it still knows who Sam is.
The sky, computed
Checked against NASA, to the arcsecond.
Your chart comes from NASA JPL’s planetary ephemeris — the kind used to navigate spacecraft — and we check it against NASA directly. Every planet lands within one arcsecond: about the width of a dime seen from two miles away.
It never makes up where a planet is. The sky is computed first; the words are written over it. That’s how it can tell you, plainly, when Mercury isn’t retrograde.

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 one-to-ten — never the words — and only while it’s switched on.
- No invented rankings. When two people are a few points apart, it calls them level, because the difference isn’t real.
Your people todayExample
- Sam72Easy company today — a good day to make the plan.
- Theo53Level with Jules — too close to call, so it doesn’t.
- Jules51Mars is pushing on your Moon: keep it short.
Memory that’s honest
It notices patterns. Then it checks them.
Anyone can tell you that you always feel off around the full moon. My Sign only says something like that when your own check-ins hold it up: enough days, a real difference from your usual, and odds that rule out coincidence.
The AI can suggest a pattern. Plain arithmetic decides whether it’s true. That takes about three months of check-ins — until then, it tells you it doesn’t know yet.
Suggested · day 30Example
You feel worse around the full moon.
✕ Not said. Four full moons can’t tell a pattern from luck.
Checked · day 120Example
The day after the Moon crosses your Saturn, your mornings run low.
✓ Said — it held up against your own history.
Privacy
What you tell it stays yours.

Nobody reads along
No ads, no data brokers, no analytics that can see what you write. Our team doesn’t read conversations as a matter of routine — the few exceptions are written down.

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, your planets’ signs and the aspects between them still hold. 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 over 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. Your first note will be waiting in the morning.
