About
Built for clarity, not spectacle
Astralis is a free web tool for people who want birth-chart math first and language second — the opposite of a daily sun-sign column.
What we are
A local calculator for tropical Western charts with Placidus houses and sidereal Vedic charts with Lahiri ayanamsa and whole-sign houses, with optional plain-language interpretation on top.
What we are not
We are not a substitute for a trained astrologer, a doctor, a therapist, or a lawyer. Remedies and dosha notes are cultural and interpretive context — not prescriptions.
Design stance
Scientific astrology means: use exact birth data, show the positions, say when a result is approximate, and keep the interface quiet enough that you can think. If something feels mystical for its own sake, we cut it.
Your sessions
Charts and matches can be kept on this device and shared as a link. Print or save as PDF from the browser when you want a paper copy. Share links encode birth details in the URL — treat them like private information.
