Meet XiNiS AI, Your Personal Astrologer
XiNiS AI reads your chart through the lens of Jungian analytical psychology. It maps planetary archetypes (the Hero/Sun, the Great Mother/Moon, the Shadow/Pluto) onto your unique chart to reveal individuation paths, relationship dynamics, and unconscious patterns.
Available as a separate service on Telegram. The calculator you see here is and always will be completely free. AI interpretation is a premium feature offered through the Telegram Mini App.
XiNiS AI is currently undergoing a major upgrade. The Telegram Mini App is temporarily offline while I rebuild the AI engine from the ground up. The free calculator remains fully operational.
