How we plan to evaluate Claude

Planned evaluation

We plan to evaluate Anthropic’s Claude for explaining structured saju information in clear English and Korean, drafting personalized reading reports, and assisting web development.

  • Explain traditional concepts in everyday language without losing their cultural context.
  • Evaluate translation quality and consistency with the supplied saju data.
  • Test report workflows, responsible handling of personal data, and practical latency and cost.

These capabilities are under development or evaluation, not live features. Fullmoondam is an independent service and is not affiliated with or endorsed by Anthropic.

A Korean service,
with a broader horizon.

Fullmoondam (만월담) is a South Korea-based saju service established in May 2026. We currently offer online consultations and written reports, and are preparing a web service for a wider international audience.

Our goal is simple: make saju explanations easier to understand, while being clear about the limits of this traditional interpretive practice.

A few things to know.

Clear expectations matter, especially when exploring a tradition for the first time.

Can I get an English-language reading today?

The English-language experience is in development. Our current services are Korean-language. Please contact us to ask about our plans and availability; this page does not promise an English service is already available.

Does saju predict what will happen to me?

Saju is a traditional cultural and interpretive practice, not a scientifically verified way to predict outcomes. Treat a reading as a perspective for reflection, not a substitute for your own judgment or professional medical, legal, or financial advice.

How is AI involved?

We plan to evaluate Claude for multilingual explanations, report drafting, and web development. The planned AI features are not live. Evaluation will focus on language quality, consistency with the supplied information, and responsible handling of personal data.

Should I send my birth details by email?

Please start with a general service inquiry and do not send sensitive personal information. Before providing birth date, time, or other information, ask how it will be used, stored, and deleted. This page has no birth-data form, booking system, or payment function.

Curious about saju?

Ask about our current services or the international experience we are preparing. We will use your inquiry to discuss the service with you, not as an invitation to send sensitive birth information.
