Jasper AI has positioned itself as a content‑creation powerhouse, but its "Chat" feature has evolved into a full‑fledged conversational agent that SaaS companies can embed on their websites. Built on GPT‑3.5 and GPT‑4, Jasper’s chat platform allows users to create character‑driven conversations, set tone preferences, and integrate with existing knowledge bases via API.
