HOW TO DO USER RESEARCH WITHOUT USERS: THE SYNTHETIC USER GUIDE

Summary from the TLDR Marketing newsletter

AI-generated personas give early-stage teams a fast way to clarify who they are building for and what those users care about. Tools like ChatGPT can create realistic, behavior-driven personas that reflect motivations, fears, workflows, and decision triggers without long research cycles. These personas help teams pressure test ideas, refine messaging, simulate interviews, and uncover blind spots before talking to real users. The approach speeds up alignment and improves product decisions while still requiring real user validation later on.
