Openly said

AI transparency at Lunela

Lunela loves telling stories about the sky. What we do not tell is a fairy tale about how they come about. So here it is, openly: where artificial intelligence contributes with us — and where it does not.

What Lunela calculates itself — entirely without AI

The astronomical foundation is real computation, not a language model: positions of the Sun, Moon and planets, ascendant, houses, aspects, moon phases and the lunar calendar are calculated exactly from ephemeris data. The same birth data always yields the same chart.

Our calculators work purely computationally as well — as does the compatibility score in the partner horoscope.

Where artificial intelligence contributes

From the calculated positions we create a text that sounds as though someone were speaking with you. Artificial intelligence takes over that step. Specifically, this concerns:

What technology is behind it

For the texts we use the language model interface of Anthropic PBC (USA), and for Luna's voice a speech synthesis service by Google. Your data is not used for training. Which data exactly is transmitted, and on what legal basis, is set out in our privacy policy.

How to recognise AI content from Lunela

We label our AI-generated content twice over:

If you would like to check a file from us: open the file properties or the metadata — there you will find the note that the content was generated with AI support. Questions about this? Write to us at kontakt@lunela.de, we answer honestly.

And what none of this is

The readings at Lunela serve entertainment and your personal self-reflection. They are not a prediction of the future and do not replace medical, psychological, legal or financial advice. If you are not doing well, please speak to a person who can help — Luna listens, but she does not treat.

Legal framework

We provide this information pursuant to Article 50 of Regulation (EU) 2024/1689 (AI Act), which has applied since 2 August 2026. The provider named in the legal notice is responsible.
