See the architectureQuestions, answered plainly
Before you begin.
Does the AI calculate my birth chart?
No. Dedicated astronomy code calculates planetary positions and application code derives chart structure. The AI receives verified structured data for interpretation.
What happens when I do not know my birth time?
Northgleam uses a clearly marked date anchor for planetary positions and removes the Ascendant, Midheaven, houses, and angle claims.
Which zodiac and house system does the starter use?
Tropical zodiac, mean lunar nodes, and Whole Sign houses. The settings remain visible in the chart and methodology.
Is the chart scientifically able to predict my fate?
No. Astronomical positions can be calculated precisely, but astrology is presented as symbolic reflection and entertainment, not validated fate prediction.
