A practitioner forgot to stop screen sharing. The Threads post went viral, and outsiders finally saw how an AI-assisted video reading works.

“The chart goes to the model as structured text first. A person turns what comes back into plain language the client can follow.”

Chart data that works for you and for AI.

Copy the packet into ChatGPT or Claude and keep the conversation going.

Divination

Not a birth chart—one question about one matter.

One question per cast. You supply the cast—we never do it for you, and we don't call good or bad luck. We chart the result so you can verify it.

How it works

Your chart stays yours—use any AI you trust.

  1. Enter birth details and build an accurate chart here first.
  2. Astralium charts it with the right system for that tradition.
  3. Copy the packet into ChatGPT or Claude—so it can read the chart and go deeper.

FAQ

What is Astralium (getastralium.com)?

Astralium (getastralium.com) is an AI charting site for BaZi, Zi Wei, Western and Vedic astrology, Liu Yao, and Qi Men: accurate charts first, then copy-ready packets for ChatGPT or Claude—no locked-in verdicts; you or AI interpret. Free to try, no sign-in.

How is this different from pasting my birthday into ChatGPT?

ChatGPT writes well—it doesn't guarantee rule-faithful charting. Astralium engines the chart first, then gives you checkable structured data and reading prompts. Data first, then questions.

Do I need to sign in? Is it free?

Core charting and copying the AI packet work without sign-in. An account unlocks saved profiles and other extras.

How do you verify chart accuracy? Is the method public?

We maintain about 58 fixed automated regression checks: golden samples lock the baseline across chart output and copyable packets—self-run regression, not a third-party audit. Public method and spot-check cases: https://getastralium.com/blog/how-we-verify-chart-engines

Where is the data I enter stored, and how is it protected?

Charts are computed in your browser, and using the site signed out produces no database writes. What you actively save after signing in — birth profiles, and the clients, cases and packet versions a practitioner creates — lives in Supabase, where the boundary between accounts is enforced by row-level security in the database rather than in the application. Every response carries five security headers; the script-src contains no 'unsafe-inline', and securityheaders.com rates the set A+.
