An AI persona is a defined character or identity that a software system presents to users through conversation, voice, or written replies. The persona usually has a set name, backstory, and consistent tone that the system is built to maintain across interactions.
The term shows up constantly in reporting on companion apps and chatbot products, where the appeal depends more on how convincing and consistent the character feels than on raw technical capability. Knowing the phrase helps readers separate products built around scripted characters from services where a real person is doing the talking.
Also called: AI character, chatbot persona, virtual persona, digital persona, AI companion character
