You can reduce what Meta AI has available by sharing less in prompts, clearing its AI conversation history where the app provides that control, and reviewing your broader Meta privacy settings. These steps have different effects: the reviewed Meta materials do not establish one switch that prevents every kind of data processing across all Meta apps. Controls can vary by app and region.
1. Share less in Meta AI prompts
Treat anything you type or upload as information you are providing to the service. Avoid entering sensitive personal, financial, medical, identity, or confidential work details unless you have considered the need and the product’s applicable terms. This limits what you disclose in a prompt; it does not change Meta’s broader data collection practices.
2. Clear Meta AI conversation history
Meta’s generative-AI system card says recent conversation history can inform later responses. It documents these commands for removing AI copies of chat history:
/reset-aideletes one AI’s copy of your chat history./reset-all-aisdeletes AI copies of your chat history across AIs.
These commands are documented in a system card last updated September 27, 2023. Check the current app’s Help or settings to see whether the commands remain available and how to use them in that version. Meta describes deleting an AI’s stored copy of conversation history; the reviewed sources do not establish that deleting a visible thread from an inbox does the same thing.

Meta also says that deleting a piece of information does not change a model in that moment, while deleted information will not be used for future training. That statement reflects the system-card context; it does not establish that every current Meta AI product follows an identical process or that deletion removes every account record.
3. Review Meta’s broader privacy controls
Meta lists several account tools for different purposes. They can help you manage account data and privacy, but the reviewed material does not say they amount to a universal opt-out from AI training.

- Privacy Checkup helps review privacy settings.
- Accounts Center and Meta’s privacy tools and information-security resources provide account-level settings and information about data practices.
- Meta provides tools to access, manage, download, or delete personal data. These address account data requests; they are distinct from resetting AI chat history.
- Ad preferences and controls for information businesses send about your activity on other apps and websites relate to advertising and off-Meta activity. Do not treat them as controls over every AI training input.
Meta’s Facebook explainer describes Meta AI as integrated into Facebook and says it can be muted or adjusted through account settings and Facebook privacy tools. It does not establish a universal process for fully disabling every Meta AI feature. See Meta’s Facebook guide to using Meta AI for its explanation of available controls.

Meta’s system card says public, licensed, and Meta product or service information can be used to train generative-AI systems. It says public or licensed personal information is not specifically linked to a Meta account in that context. This description does not resolve every current objection or opt-out process, or show that clearing a chat reverses prior training.

For people in the United States, Meta’s US Regional Privacy Notice, effective May 23, 2025, describes rights to access, correct, or delete personal information and to opt out of targeted advertising, subject to applicable law and exceptions. Those rights are specific to the notice’s US scope; an advertising opt-out is not an AI-training opt-out. The reviewed sources do not settle current AI-training objection procedures in every country or specify a fixed timeline for removing a deleted chat from all internal systems.
