    It may be unclear which underlying AI model version is being used, how up-to-date it is, or what modifications have been made to the base model's behavior.
  • Potential Hidden Costs or Ads
    Free-to-use AI wrapper sites often monetize through ads, premium upsells, or data collection, which may not be clearly disclosed to users upfront.

Questions & Answers

As answered by people managing GetBirthChart and https://open-gpt.app/.

Which are the primary technologies used for building your product?

GetBirthChart's answer

Next.js, TypeScript, React, Python, FastAPI, Swiss Ephemeris, PostgreSQL, Redis, and AI language models for interpretation.

What makes your product unique?

GetBirthChart's answer

GetBirthChart separates deterministic chart calculation from AI interpretation. Planetary positions, houses, angles, and aspects are calculated first from birth data, then AI explains how those factors interact. If the birth time is unknown, time-dependent results are omitted rather than guessed.

Why should a person choose your product over its competitors?

GetBirthChart's answer

GetBirthChart focuses on transparent calculations, clear handling of uncertain birth data, and interpretations that combine placements, houses, and aspects instead of treating each factor as an isolated personality trait. It also provides free chart tools and an open-source calculation engine.

How would you describe the primary audience of your product?

GetBirthChart's answer

People who want to calculate and understand their birth chart, from beginners exploring their Sun, Moon, and Rising signs to users interested in aspects, houses, compatibility, synastry, and yearly transits.

What's the story behind your product?

GetBirthChart's answer

GetBirthChart was built around a simple idea: chart calculation and interpretation should be separate. The project began with a deterministic astrology engine using Swiss Ephemeris, then added a user-facing platform that turns structured chart data into clearer explanations and interactive tools.
