About AstroAxis
A free set of astrology and numerology calculators, built and kept running by one independent developer.
What AstroAxis is
AstroAxis is a set of free calculators for people who want the actual numbers rather than a paragraph of generalities: a natal chart, personal and business synastry, a numerology profile, a Pythagorean square, a Destiny Matrix and the personal-day card. Nothing is locked behind a sign-up — no accounts, no subscription, no mailing list. You enter a birth date and the calculation arrives with its interpretation on the same page.
Where the numbers come from
Planetary positions come from the Swiss Ephemeris and are computed on the server, so the ephemeris data never has to be downloaded into your browser. Houses, aspects and the extra points are derived from those positions with the standard formulas, and every calculator page explains the method it used. The numerology tools need no server at all: their arithmetic runs in your browser, which is why the result appears instantly and why nothing you type is sent anywhere.
About the AI readings
Every calculator can turn its result into a prompt you paste into ChatGPT, Claude or any other assistant, and you can also stay on the site and have a reading streamed onto the page. Either way the text is written by a general-purpose language model that sees only a short summary of your result. It is a good place to start thinking, not an authority: check anything that sounds like a fact against the numbers shown on the page.
Who is behind it
AstroAxis is an independent one-person project, not a company. The author is a developer who wanted an astrology tool that shows its working instead of hiding it, and kept building it. There is no editorial team, no astrologer on staff and no advertising deal behind any of this — which is exactly why the pages explain their method and stop honestly where the method stops.
