Overview

Asteria supports advanced astrological charting workflows for users who need more than a simple chart viewer. It combines deterministic chart computation, archival-quality export, optional AI-assisted interpretation, and a fast Dear ImGui interface tuned for desktop work.

Highlights

  • Natal charts with Sun through Pluto, house cusps (Placidus, Koch, Whole Sign), and aspect grid.
  • Synastry bi-wheel with inter-aspect analysis.
  • Composite midpoint charts.
  • Transit-to-natal overlays with an outer transit ring.
  • Transit timeline reports with configurable date ranges, planets, and aspects.
  • Optional AI-powered interpretation via local Ollama integration.
  • SVG vector and PNG raster export with archival-quality output.
  • Atlas with 20,000+ cities, SQLite person/birth-event store, and full CLI for batch workflows.
