Is it safe to paste sensitive company data into ChatGPT or other AI chatbots?

No, pasting sensitive company data into public AI chatbots like ChatGPT or Gemini is not safe, and several major companies have already banned the practice after employees accidentally leaked proprietary code and internal financials. The problem isn't that the AI is malicious. It's that your conversations can be reviewed by human trainers and might be used to improve the model. Samsung learned this the hard way in 2023 when engineers pasted confidential source code into ChatGPT to debug it. The data wasn't 'hacked' in a traditional sense. It simply became part of the training pipeline, and Samsung had no way to pull it back. Think of a public chatbot like a whiteboard in a busy coffee shop. Great for brainstorming general ideas. Terrible for writing down your bank password. The safer approach is to use enterprise-tier versions that offer data privacy agreements, like ChatGPT Enterprise or Microsoft Copilot with your organization's tenant. These typically won't use your data for training. For individuals, a good rule of thumb is to treat the chat window like a public forum. If you wouldn't tweet it, don't paste it. You can also turn off chat history in ChatGPT's settings, which prevents your inputs from being used for model improvement, though it doesn't guarantee zero human review for safety purposes. **Related**: What are prompt injection attacks? | How do enterprise AI tools protect company data?
