Marselia works with one deck only: the 78-card Tarot de Marseille in the pattern Nicolas Conver engraved in 1760, shown from scans held by the Bibliothèque nationale de France. For a single card, the site shuffles and cuts for you and you tap one face-down card. If you want the whole ritual, you shuffle seven times, cut with your left hand, fan the deck out and draw each card into its position yourself. A random generator decides the cards; the AI only reads what came out.
What sets it apart from most online tarot is that every draw can be checked afterwards. The server shuffles first and publishes a SHA-256 fingerprint of that shuffle before you touch the deck. The key is revealed with the result, and the proof page lets anyone redo the calculation and land on the same cards. The site is clear that this proves the draw was not rigged, not that the reading is right.
Readings are written by Anthropic's Claude from the cards and your question, then read aloud with an ElevenLabs voice you can replay. Tarot reader Camille Kroely reviewed the reading rules and the 78 upright and reversed meanings, but no person checks individual readings, and Corinne, the reader pictured on the site, is openly fictional. If you already laid out a physical spread, you can photograph it or name the cards one by one and get a reading from the same method.
Without an account you get two single cards a day. The first reading of the day appears at once; later free readings wait in a queue for about 2 to 13 minutes. Three cards for past, present and future, a clarification card, or skipping the queue costs 1 credit each, and the five-card cross costs 2. Credits come in packs from €2.99 for 3, never expire, and there is no subscription. The site also has an entry for each of the 78 cards and a catalogue of 58 historical decks, in 12 languages including Chinese, Japanese and Korean.
