What is ChatGPT?
ChatGPT is an AI assistant from OpenAI that answers questions, writes and edits text, analyzes files and creates images through a chat interface. Marketers use it to draft blog posts, ad variations, emails and social captions, brainstorm campaign ideas and summarize research. It runs on OpenAI's GPT-5.5 models, with faster Instant and deeper Thinking modes depending on the plan.
ChatGPT also includes ChatGPT Images, which generates and edits pictures from text prompts inside the same conversation. Paid plans add deep research, agent mode, projects, custom GPTs, longer memory and more uploads, while Business and Enterprise plans add shared workspaces, admin controls and a promise not to train on company data. Apps are available on the web, desktop and mobile.
