Well, bots in roleplays typically have different color text or are identified by their name. For example, if a bot's name is "NPC" or "Bot XYZ," it might be labeled with colors other than default black text. However, some roleplayers may prefer not to use colored text for bots as they try to create a more immersive experience. In those cases, you can simply identify a bot by its writing style or the nature of its responses.
