Frequently Asked Questions
Is it safe to share documents with ChatGPT?
Not without precautions. ChatGPT uses conversations for training by default. Always anonymize sensitive data before sharing to prevent it from being used to train AI models.
Does Claude use my data for training?
Claude doesn't train on your data by default, making it more privacy-friendly. However, for highly confidential information, anonymization is still recommended as conversations may be reviewed for safety purposes.
What about enterprise AI accounts?
Enterprise accounts (ChatGPT Enterprise, Claude Enterprise) typically have stronger privacy guarantees and don't use your data for training. Check your organization's specific agreement for details.
