OOTKThoth Engine

Free and open source

Welcome to the Opening of the Key

Draw a Thoth spread. OOTK looks up every card in the Book T and Liber 777 tables, works out how the cards relate, and hands your AI a ready-made prompt, so the interpreting is left to your AI.

  1. 1 Ask your question and draw
  2. 2 Save the prompt
  3. 3 Attach it in your AI

The cards don't depend on your question; your AI's reading does.

Which part of life does it touch?
How deep do you want to go?

Which cards should be drawn?

The seed is the starting point for the shuffle: it decides which cards come up and in what order. Leave it blank for a new random shuffle. The same seed and settings always draw the same cards.

Which tradition should the cards follow?

This changes the letters, paths and colours your AI is given, not which cards are drawn.

What kind of story should your AI tell?

It only changes the angle your AI reads from, not the cards or the scores. More

The angle your AI is asked to read from. It does not change the cards or the scores. More

Birth cards · optional

Your birth card and year card, from tarot numerology as Mary Greer and Angeles Arrien (writing for the Thoth deck) teach it: the numbers of your birth date added up to a Major card. The prompt names them and says if any were drawn. More

Stays in your browser; only the card numbers are sent, and they are left out of share links.

Parts of the AI prompt · standard

The standard set gives the full reading. Switch a main part off to see what your AI makes of the reading without it, or add an extra layer. The cards drawn stay the same, and the prompt tells your AI what was left out. Which parts AIs use.

Main parts
Extra layers (off unless you add them)

Each repeats another part, is the same in every reading, or made no difference when tested.

Three diagrams in turn. The Tree of Life: its 22 paths light up one at a time, each with its Hebrew letter and Thoth trump, from Aleph (The Fool) to Tav (The Universe). Then the zodiac: its 36 decans light up one at a time from 0° Aries, each with its ruling planet and small card, from the 2 of Wands to the 10 of Cups. Then the aspects on that wheel: its oppositions, squares, trines and sextiles drawn in turn, then all 42 together.
