# How to Build Audience Segments with ChatGPT

ChatGPT generates personas as rich, narrative profiles that bring your target audience to life in a format anyone on your team can understand. Describe your product and market, and receive detailed buyer or user personas with motivations, objections, channel preferences, and day-in-the-life context explained in accessible language. The collaborative format makes it easy to share personas across marketing, product, and sales teams, and ChatGPT can tailor the output for different audiences -- detailed for strategists, concise for executives.
