Verdict: ChatGPT has adequate security but significant privacy considerations. Conversations are used for training by default, and sensitive data shared in chats could be exposed. Use the opt-out settings and avoid sharing confidential information.
ChatGPT is the most widely used AI chatbot with over 100 million weekly active users. It uses conversations to improve its models by default, which means anything you type may be reviewed by OpenAI staff or used in training data.
