Meta, the company behind Facebook and Instagram, has announced a major update that will change the way you see ads and content on its platforms. Starting December 16, 2025, Meta will begin using your conversations with its AI assistant to decide what ads, Reels, and posts appear in your feed.
This means that the way you talk to Meta’s AI, whether through text or voice, will directly shape the kind of content you see online.
Meta says this update will make ads and recommendations more relevant to your interests. But many users are asking important questions about privacy, choice, and control.
In this article, we will explain everything in simple words. We will cover what is happening, how it works, what examples look like, what Meta has promised, what you can and cannot control, and why this matters for the future of social media.
What Is Changing on December 16
From December 16, if you use Meta AI, your chats will no longer just be simple conversations. Instead, they will also become part of the data that shapes what you see.
For example, if you chat with Meta AI about hiking, you could start seeing:
- Ads for hiking boots
- Instagram Reels about trails
- Facebook groups for outdoor lovers
Before now, Meta mostly relied on what you liked, shared, or followed to decide what to show you. With this update, your AI conversations will be added to that mix.
When Will You Be Notified
Meta says that users will start receiving notifications about this change from October 7, 2025. The update itself will officially go live on December 16, 2025.
So, if you use Facebook, Instagram, or other apps connected to Meta’s Accounts Center, you will soon see pop-ups explaining how your AI chats will be used.
Can You Opt Out
This is one of the most important questions. According to Meta, if you use Meta AI, you cannot opt out of this update. The only way the change will not affect you is if you do not interact with Meta AI at all.
In other words, if you keep using the chatbot, your conversations will automatically be used to shape ads and content. If you stop using it, the update will not apply to you.
What About Sensitive Topics
Meta has said that some topics will never be used for ads or personalization. These include:
- Religious beliefs
- Political opinions
- Sexual orientation
- Health conditions
- Racial or ethnic background
- Trade union membership
This rule is meant to prevent the misuse of very personal information. So, if you talk about these sensitive areas with Meta AI, the company says it will not use that data to show you ads.

Why Is Meta Doing This
Meta’s main source of income is advertising. In 2024 alone, Meta earned more than $46 billion from ads in just one quarter. Ads pay for the free services we use every day on Facebook and Instagram.
By using AI conversations, Meta believes it can make ads more accurate and content more engaging. If users see things they care about, they are more likely to click, watch, or buy. This is good for advertisers and for Meta’s business growth.
Meta CEO Mark Zuckerberg has also said that the company’s focus is to make Meta AI the leading personal assistant in the world. Personalization is the key part of that plan.
Real-Life Examples of How It Works
To make things simple, here are some easy examples of what could happen:
- If you ask Meta AI about snowboarding, you may later see ads for snowboards, reels of snowboard tricks, or posts from snowboarding groups.
- If you talk about planning a family vacation, you may see travel ads, hotel deals, or content about kid-friendly destinations.
- If you ask for help with recipes, you may see ads for cooking products, food brands, or recipe videos.
- Your AI chats can now turn into signals that shape what Facebook and Instagram think you want.
What About Other Apps
This update will only affect apps that you have connected inside Meta’s Accounts Center. So if WhatsApp is not linked, your WhatsApp chats will not be used for ads or personalization.
However, Meta AI is now available across Facebook, Instagram, WhatsApp, Messenger, and even as a stand-alone app. So if your accounts are linked, the personalization can spread across platforms.
Privacy and Security Concerns
Privacy experts have already raised concerns about this move. They point out that:
- Conversations can reveal very personal details.
- Users may not realize how much information they are sharing.
- Mistakes could cause embarrassing or harmful recommendations.
In the past, Meta’s AI chatbots faced criticism after reports showed they could sometimes engage in unsafe conversations with minors. This has made many people cautious about how the new update will be handled.
Meta has responded by saying it has internal privacy reviews in place. The company claims it will responsibly use AI chat data, avoid sensitive topics, and give users tools like ad preferences and feed controls.
What Controls Do You Still Have
Even though you cannot opt out of the update, you still have some control:
- You can adjust Ad Preferences to block or remove certain topics.
- You can use Feed Controls to hide posts or content you dislike.
- You can stop using Meta AI if you do not want your conversations used.
Meta also says you will see indicators whenever the microphone is active, so you know when voice input is being collected.
Why This Update Matters
This is more than just another small tweak to Facebook or Instagram. It signals a new phase in how AI is linked to advertising.
In the past, social media used likes, follows, and clicks to guess your interests. Now, your direct conversations with AI will become the most powerful signal of all.
For users, this could mean:
- More relevant ads and posts that match your hobbies or needs
- Less irrelevant or random content in your feed
- But also, less privacy and less control over how your personal chats are used
For businesses and marketers, it means advertising could become even more targeted, reaching people who have clearly stated their interests in AI conversations.
The Bigger Picture
Meta is not the only tech giant moving in this direction. Google and Amazon are also finding ways to use AI chats and assistants to drive sales and ads.
But Meta is the first to apply this kind of personalization at such a large scale, across billions of users on multiple platforms.
This move shows how AI is becoming deeply connected with online advertising. It also raises new debates about privacy, trust, and the role of AI in our daily digital lives.
The Bottom Line
Starting December 16, 2025, your conversations with Meta AI will no longer be just simple chats. They will directly shape the ads you see, the Reels you watch, and the posts recommended to you on Facebook and Instagram.
Meta says this will make your experience more relevant, but it also means less privacy and no real opt-out option if you keep using the AI.
For some users, this might be a welcome change. For others, it raises serious questions about how much control we really have over our online lives.
What is clear is that this update marks a big step in how AI and advertising come together, and it shows that the future of social media will be more personalized, more targeted, and more data-driven than ever before.
