Founding members, gathering now
The sky today,
written for your chart.
Ephemeris is a chart-based daily companion: your birth chart held steady while the sky changes. The natal chart page is shipping now; week-ahead notes and chart chat are on the horizon.
Join at the beginning, then begin with your chart whenever you’re ready.
The first circle
Come in while the constellation is still being drawn.
Founding members are helping shape a careful chart-based companion — one that earns its place in a morning rather than filling the screen with noise. You’ll start with the natal chart page, then have a say in what the next pieces become.

How it works
One chart, drawn once. Read every day after.
Onboarding keeps you long enough to get the geometry right — the birth details, the timezone, the house system — and then stays out of the way.
- 01
Start with the natal chart page
Date, time, place, and the house system that fits your tradition. The natal chart page is the first piece shipping now.
- 02
A fixed chart that stays put
After the first draw the chart never moves. The sky moves around it. Every note is interpreted from the same geometry, so it can be reread, revisited, and disagreed with.
- 03
Help shape what comes next
Founding members will help decide how week-ahead notes and chart chat become part of the same thoughtful rhythm.
The roadmap
What is here, and what is next.
The first release is deliberately small. The natal chart page is available now; week-ahead notes and chart chat are being shaped for the horizon, with founding members close enough to influence the details.
- Shipping now
Natal chart page
Your birth details become a fixed natal chart you can return to. It is the first piece of Ephemeris, and it is shipping now.
- The foundation
A daily companion
The long-term shape is a quiet daily reading against that chart — useful, specific, and never padded for the sake of a feed.
- On the horizon
Week-ahead notes
A longer view of the next seven days, read from the same fixed chart. This is a future capability we are shaping with founding members.
- On the horizon
Chart chat
A thoughtful, conversational way to ask better questions of your chart. It is on the horizon, not part of today's release.
Voice
“The note is short on purpose. Aries in your seventh house today doesn’t need three paragraphs of throat-clearing — it needs one careful sentence and a question you can sit with on the train.”
Warm. Careful. Lightly self-aware about the strange territory it lives in. It does not ask the user to wish harder.

Founder reading
A small tier we don’t advertise.
A two-hour session with the founder — the person who built the chart engine, not a customer-support rep. By invitation, kept small so it stays useful. If a longer conversation sounds right, write to us.
