Online tarot tools, of course, work in a similar way, where the archetypes and symbolism can be read and understood depending on any situation that is asked of them. However, the human element is missing, and replaced by an algorithm. The human element, and the energy of the person giving the reading, is the main element of the tarot card. A true card reader could pick up any deck of cards, whether they are tarot or not, and give you a reading that applies to your life, because of their deep intuitive gifts. The computer algorithm of an online tarot card tool doesn’t quite work like that, so while you might get some insight into a situation, it won’t be quite as personalized as you might hope.  As long as you are careful and make sure to receive readings from actual people as well as consult online tarot cards, there’s no harm in it; just be aware that you might not be receiving the most personalized experience, and therefore not getting the most accurate answers.
