Overview
Who is it for?
People who want to calculate and understand their birth chart, from beginners exploring their Sun, Moon, and Rising signs to users interested in houses, aspects, compatibility, synastry, and yearly transits.
Problem
Most astrology tools either give generic placement descriptions or hide how the chart was calculated. They may also guess time-dependent results when birth time is missing, which can make Rising signs and houses unreliable.
Solution
GetBirthChart calculates planetary positions, houses, angles, and aspects first as structured chart data, then uses AI to explain how those factors interact. If the birth time is unknown, time-dependent results are omitted instead of guessed.
What makes it unique
GetBirthChart separates deterministic chart calculation from AI interpretation. The calculation layer is inspectable through the open-source gbc-astro Python engine, while AI is used only after the chart has been calculated.

Discussion1
I built GetBirthChart around one rule: calculate first, interpret second. The chart engine computes placements, houses, angles, and aspects before AI is used to explain how they interact. If birth time is unknown, time-dependent results are omitted instead of guessed. The core calculation engine is also open source as gbc-astro. Would love feedback on the chart experience and interpretation flow.
