The Opening of the Key is the Golden Dawn’s longest tarot method: a significator, then the twelve houses, the twelve signs and the 36 decans. OOTK deals each operation from a seed you can repeat and tabulates the result.
- Draw your cards. Ask your question and pick a spread. The seed makes the draw repeatable.
- Copy the prompt. The report lists every card’s correspondences, dignities and aspects, written up for an AI.
- Open it in your AI. Paste it into ChatGPT, Claude, Gemini or another model, which writes the interpretation.
Free, with no sign-up. OOTK does not interpret the cards itself; it gives your AI the facts to work from.
