Meta will start using AI conversations to customize content and advertisements in December

Meta has announced a significant policy shift that will reshape how it delivers personalized content and advertising to users. Starting December 16, 2025, Meta platforms will use data gathered from AI chat tools—including messages sent via AI assistants—to further refine and personalize the ads and content users see across its platforms, such as Facebook, Instagram, and WhatsApp[1].

What This Means for Users

Under the new system, Meta’s AI-driven algorithms will analyze interactions with AI chat features—including user questions, requests, and responses provided by AI assistants—to build more detailed user profiles. These profiles will then inform which advertisements and content appear in your feed, potentially making them more relevant to your interests and behavior.

• Meta will begin notifying users about this change starting October 7, 2025[1].
• The new data use policy will officially take effect on December 16, 2025[1].
• Users will see ads and content that are more closely aligned with their conversations and interactions with AI tools.

Privacy and Data Use

This expansion into AI chat data marks a new frontier in social media personalization, but it also raises questions about privacy. Meta has stated that the data will be used in compliance with local privacy laws, but users concerned about data sharing may need to adjust their privacy settings or limit their interactions with AI chat features to maintain control over their information.

Broader Impact on Digital Advertising

By leveraging AI-driven chat data, Meta is positioning itself at the forefront of hyper-personalized digital advertising. This move could set a new industry standard, prompting competitors to adopt similar strategies and potentially increasing the effectiveness—and intrusiveness—of targeted ads online.

Looking Ahead

This policy change is expected to enhance the user experience by delivering more relevant content, but it also highlights the growing role of AI in social media and the importance of understanding how your data is used. Meta users are encouraged to review their privacy settings as the December 2025 deadline approaches.
