Eliza is a computer program that can talk to people and make them feel better by acting like a therapist. It works by taking what you say and helping you talk about your feelings. For example, if you say, "I'm feeling sad today," Eliza might respond by saying, "Why do you feel sad?" This might help you explore your feelings and figure out what's bothering you. Eliza is kind of like having a pretend therapist that you can talk to whenever you want.
