Tool Β· 50 cases

Use cases: ChatGPT

ChatGPT, from OpenAI, is the tool cited most often in the directory's cases. It shows up in everyday tasks, such as proofreading, organizing finances and preparing for appointments, and in professional uses, such as sales proposals and lesson plans. The free version handles a good share of the examples; some accounts use paid features such as file analysis and voice. See what each person asked for, how they adjusted the conversation and copy the prompt to try it.

50 cases, 34 of them from Brazil, from newest to oldest. The most common topics are productivity, health, and marketing and content. People who show up most: patient, student, and parent. Each case links to the original source, shows a verification date and includes a prompt we wrote.
