GoKawiilMajor AI chatbots let users opt out of having conversations used for training
OpenAI, Anthropic, Google, Microsoft and xAI all allow users to opt out of having their chat conversations used to train future models, a process that takes about a minute per service and doesn't affect personalization or memory features. Meta is the exception: US users cannot opt out of training on Meta AI chats, and since December the company has used those chats for ad targeting without any opt-out option.
GoKawiil's interpretation of the reporting above, not reported fact.
Opting out only affects future conversations, not past ones, and doesn't delete data already collected, so users remain bound by each company's retention policies regardless of their settings. Meta's lack of an opt-out, combined with its use of chats for ad targeting, sets it apart from competitors and could raise privacy concerns among users who assume similar controls exist across all AI platforms.
- Most major chatbots (ChatGPT, Claude, Gemini, Copilot, Grok) offer an opt-out from training data use.
- Meta AI is the only listed platform where US users cannot opt out of training, and it also uses chats for ad targeting.
- Opting out doesn't erase past conversations or delete data already retained under each company's policies.
