Tarot that asks what you see, and knows what the sky is doing.
Every tarot app deals a card and writes warm generalities. This one asks what you see before it says anything, and when the Moon or a planet is on your card, it says so, with the date it moves on.
Or .
The deck. Seventy-eight cards, drawn in 1909.
Say it in your own words.
It reads the shape of the question and lays the spread built for it, with the reason. Or choose one of the thirteen yourself.
Your intuition goes in first.
A reader asks what you notice before they interpret, because the half you supply is the half that makes it yours. The card turns, nothing is written yet, and the detail your eye went to becomes the material the reading is built from.
Then it reads from all three at once.
What you saw, the card in its position, and where the planets actually are at that minute. Change any one of the three and the reading changes.
Keep a reading and in a few days it asks how it went. The next one can say three weeks ago you drew the Three of Swords about this.
Thirteen spreads.
The classics, and a few built for one kind of question. Tap one to lay it.Shuffled and sealed.

Two things no other tarot does.
Every AI tarot app deals a card and writes warm generalities. Decan Tarot asks what you see before it says anything, and it computes where the Sun, the Moon and the planets actually are while it reads. One of those is a method no competitor uses. The other is arithmetic a language model cannot do reliably.
1. Your intuition goes in before the interpretation
The card turns over and nothing is written yet. It asks what draws your eye first, you tap a detail from that specific card or say it out loud, and only then does the reading arrive, opening from your answer.
This is how a human reader works and it is the step digital tarot deleted. The card is ambiguous on purpose; the half you supply is the half that makes the reading yours. Two people turning the same card and noticing different things get two different readings, and both are right.
It is also the part that cannot be lifted by a competitor in an afternoon. What people notice in a given card is a record that only exists once thousands of draws have been made, and every rival optimises for the opposite thing: fewer taps to the reading.
2. It prints one sentence you could check
Every numbered card in the deck was assigned ten degrees of the zodiac by the Golden Dawn in 1888. This site runs an ephemeris while you read, so when the Sun, the Moon or a planet is inside your card’s ten degrees at that minute, the reading says so and gives the date it moves on. When nothing is there, it says nothing.
That sentence would be false if it were wrong, which makes it the only checkable claim in any tarot product. It is why the card lights gold on the cloth when the sky is on it, and why the reading separates what is a fact from what is a reading, in two different typefaces.
It is hard to copy for a dull reason: it needs a real ephemeris, handling current degrees, retrogrades and ingress dates, wired to thirty-six cards without a single error and kept accurate for ever. Language models get this class of arithmetic wrong.
3. It comes back and asks how it went
Keep a reading and it saves the cards, your answers and the sky they were drawn under. A few days later it asks how it actually went, in one tap, and that answer becomes part of the record. The next reading can refer to the last one.
Over a year that is a journal that writes itself and a record of your own hit rate, kept for you and never turned into a marketing claim.
4. The draw is sealed before you touch it
The order of the deck is fixed and fingerprinted before the wheel is touched, your spin is mixed into it, and the seed is shown after the turn so anyone can recompute the draw. Nobody, including the engine, sees your card before you do.
Cutting the deck is what allows a card to come up reversed. Without a cut, none do, which is truer to the physical object than a coin flip.
| Instead of | What they do well | Why people pick this |
|---|---|---|
| A general chatbot | Free, warm, instant, endless follow-ups | It never makes you look first, and it cannot reliably say where the Moon is tonight. Its tarot is language about language. |
| Other AI tarot apps | Polish, card backs, push notifications | Generic prose with no Socratic step and no computation behind it. The edge is distribution, not method. |
| Meaning encyclopedias | Deep reference on all 78 cards | They are reference, not a reading. This asks you a question and answers it. |
| Live psychic lines | A human on the other end | They cost by the minute. This is free, private, and available at seven in the morning. |
Questions
- Is Decan Tarot free?
- Yes. Readings are free and no account is needed to get one. An email address is asked for only if you want a reading kept and the follow-up question a few days later.
- What is a decan?
- A decan is one third of a zodiac sign: ten degrees of the year. There are thirty-six of them, and in 1888 the Golden Dawn gave one to each of the thirty-six numbered cards in the tarot, which is why a card here can be tied to a stretch of the calendar and to the planets crossing it.
- Do I need to know tarot to use it?
- No. It asks what you see, which needs no training, and the rest is explained where it matters. The Learn page covers the deck, the four suits and how a reading goes, in about ten minutes of reading.
- Which spread should I use?
- Type the question in your own words and the right spread is suggested with the reason, from thirteen: one card for the day, yes or no, past present future, the two of you, should I buy it, this or that, is now the time, what am I missing, pick one of three, mind body spirit, the horseshoe, the year ahead, and the Celtic Cross. You can always choose a different one.
- How are the cards shuffled?
- The order is fixed and a fingerprint of it is published before you touch the wheel, your spin is mixed in as a second seed, and the seed is revealed after the turn so the draw can be recomputed by anyone. It is the commit-and-reveal method used to prove a shuffle was not tampered with.
- Does it predict the future?
- No. It never predicts dated events, never gives medical, legal or financial specifics, and never claims a track record. The only date in a reading is the astronomical one, which is a fact about the sky rather than a claim about you.
- Which deck is it?
- The 1909 Waite-Smith deck, drawn by Pamela Colman Smith in London, from scans of a printing of that era rather than a modern reprint.
- Can I use it on my phone?
- Yes. It is one responsive site, and on a phone you can answer the card’s question by speaking instead of typing.
Enough to read with. Nothing you have to memorise.
How a reading goes here
You bring a question, or just the day. The spread that fits it is laid on the cloth, with each position named, and you take the cards off the wheel face down. Then you turn them, one at a time, and before anything is said about a card it asks you one thing: what draws your eye first? You tap a detail or say it out loud. The reading opens from your answer, goes through the positions, and says which lines are facts about the sky and which are readings.
That order is not a nicety. A reader who asks what you notice before interpreting is using the oldest method there is: the card is ambiguous on purpose, and the half you supply is the half that makes the reading yours. Two people turning the same card and noticing different things get two different readings, and both are right.
The deck
Seventy-eight cards. Twenty-two majors, numbered 0 to 21, from the Fool to the World, which carry the big arcs: beginnings, choices, endings, luck, judgement. Fifty-six minors in four suits, which carry daily life.
Wands are will, work and fire: what you are doing. Cups are feeling and water: what you are feeling. Swords are thought and air: what you are thinking, and the trouble thinking makes. Pentacles are the body, money and earth: what you have and what you are building.
Each suit runs from the ace, the seed of the suit, through two to ten, a story in nine steps from a first pairing to a completion, and then four court cards: the page who learns, the knight who acts, the queen who holds and the king who rules. In this deck every number card is a picture of a moment, which is why looking works.
Reading by looking
Take the Nine of Pentacles. A woman in a garden, a bird on her glove, coins on the vines, and, almost hidden by her hem, a snail. Most people go to the bird. Some go to the coins. Almost nobody goes to the snail, and the ones who do have said something about pace before a word of interpretation has been offered. The book meaning of the card is comfort earned; what you noticed is what the reading is about.
So the method is: look before you know. Name the first thing. Then let the position and the tradition catch up. A reversed card, when the deck was cut, reads as the same picture met from the wrong side: delayed, inward, or overdone.
The sky, and why a card here can carry a date
The year is a circle of 360 degrees, and the zodiac cuts it into twelve signs of thirty. In 1888 the Golden Dawn cut each sign into three parts of ten degrees and gave one numbered card to each, so that the thirty-six number cards, two to ten in four suits, cover the whole year between them. The Nine of Pentacles, for instance, owns the last ten degrees of Virgo, which the Sun crosses in early September.
The Sun, the Moon and the planets move through those degrees on a known timetable. This site runs that arithmetic while you read. When one of them is on your card at that minute, the reading says so in a gold line, with the date it moves on. When none is, it says nothing. That sentence is the one thing here that would be false if it were wrong, and nobody else prints it.
The whole table, with today marked. Tap a row to see that card's ten degrees.

The cards, one line each
Thirty-seven have pictures in this prototype. The gold lines are live.
Your birth card, and your birth decan.
Every birth-card calculator on the web stops at the first result. The second one needs the ephemeris, and it is the one that belongs to this deck.
Made from two things that are a hundred years old.
The cards were drawn by Pamela Colman Smith in London in 1909. She hand-lettered every title and signed every card, and went uncredited for most of a century. The scans here are from a printing of that era, not from a modern reprint.
The sky comes from an ephemeris, the same arithmetic astronomers use. Every numbered card was assigned ten degrees of the zodiac by the Golden Dawn in 1888, so when the site says the Moon is on your card tonight, that is a fact you can check, and it prints when it stops being true.
The reading starts from what you noticed, because that is how a reader works: they ask what you see before they say anything. Readings never predict dates, never give medical, legal or financial specifics, and never claim a track record.
How a draw is sealed
Before you touch the wheel the order of the cards is fixed and a fingerprint of it is shown. Your spin is mixed into the order. After the turn, the seed is revealed under the card so the draw can be recomputed by anyone. Nobody, including the engine, sees the card before you do. Cutting the deck is what allows a card to come up reversed; without a cut, none do.
About this prototype
Thirty-seven cards carry images here: the thirty-six numbered cards and the Moon. Six carry written chips and readings; the others take a spoken or typed observation. Nothing is saved and the email field does nothing. Sky positions are computed on the page by a compact planetary model; the build uses the Swiss Ephemeris.
