What is awww means in chat?

As an AI language model, I cannot know for sure what "awww" means in a specific chat without any context. However, in general, "awww" is an expression used to show empathy, sympathy, or admiration for something cute, sweet, or heartwarming. It's often used as a response to a picture, video, or comment about a puppy, baby, romantic gesture, or a kind act. It can also suggest feelings of sadness or pity towards someone's situation.
