AI on Facebook: Meta AI Features, Controls and Privacy

AI on Facebook in 2026 mostly means Meta AI, Meta's assistant, built into search, Messenger, the post composer and the comments under busy posts. You can switch some of it off, like comment summaries on your Page, AI-generated post titles and message sharing in a chat. Meta's Help Center doesn't describe one switch that removes Meta AI entirely. Meta says it uses your AI chats to improve its AI and, in most regions, to personalize content and ads. People in the EU and UK were offered a form to object to their public posts being used for AI training.

Everything below comes from Meta's newsroom, Help Center or Privacy Center as they read in September 2026. Meta rolls features out gradually and says Meta AI "isn't yet available for everyone," so your app may not match every row.

Where Meta AI shows up on Facebook

Search and AI Mode

Meta's Help Center says that when you search Facebook, "you may see a summary or response from Meta AI while searching." In June 2026, Meta announced AI Mode in the Search tab, which gives answers grounded in what people say publicly across its apps, such as in Groups and Reels, instead of a plain list of results.

Messenger and chats

You can open a chat with Meta AI from Messenger, or mention @Meta AI in a chat with friends. Everyone in that chat sees your message and the reply. Two details from Meta's Messenger Help Center matter most:

• Other people can share your messages with Meta AI. When someone uses an AI feature in a chat, up to 50 recent messages are shared with it. Mentioning @Meta AI in a group chat can share messages from the past 30 days, though Meta says that isn't available in all countries yet.
• Encryption has an exception. In end-to-end encrypted chats, messages that mention @Meta AI and messages from Meta AI are not encrypted. The rest of the chat stays encrypted unless someone shares it with Meta.

To keep a chat out of this, open the chat's info, tap Message permissions and turn off "Allow message sharing." Nobody in that chat can then use AI features that share messages with Meta AI. In a one-to-one chat either person can change it. In a group chat, only admins can. Meta says this setting is still being introduced gradually.

Posts, comments and groups

Help me write appears after you type a post, comment or story, and rewrites it from a prompt such as "fix grammar." AI Images generates an image from a text prompt in the same places. If you've used the "create image of me" feature, Meta says you can turn it off and delete your setup photos in Meta AI settings.

Comment summaries are the feature people most often notice without asking for it. Meta AI may summarize comments on some public posts, public group posts and Page posts with lots of comments. Your controls depend on where the post is:

• Your own post: open the summary's options and choose Remove comment summary. Meta says it won't generate a new one.
• Your Page: summaries are on by default. Admins can turn off "Allow comment summaries on your posts" under Settings, then Posts.
• A Facebook group: Meta's Help Center says you can't turn them off. Summaries on public group posts may also appear in search engine results.

AI-generated titles follow a similar pattern. Meta may add an AI title to public posts on a Page or pro mode profile, and it may show in search results. It's on by default, and you can turn off "Allow AI-generated titles on your public posts" under Settings, then Posts. A group's AI is a chatbot some groups offer for questions about group content. It's on by default for eligible groups, and admins can disable it under Manage.

Can you turn off Meta AI on Facebook?

Not with one switch, going by Meta's documentation. Meta's Help Center gives you controls for specific features: comment summaries, AI titles, a group's AI, message sharing, and the "create image of me" photos. None of those articles describes a setting that removes Meta AI from Facebook as a whole.

In practice, most of Meta AI only runs when you tap it. Ask Meta AI, Help me write and AI Images all need you to start them. The parts you'll see without asking are search summaries, AI Mode, and comment summaries and AI titles on other people's posts. For your own content, remove or turn off comment summaries and AI titles, and turn off message sharing in chats where you discuss anything sensitive.

If you manage accounts for work, AI tools for social media covers where AI is actually worth using on the posting side.

What Meta does with your data

The rules here differ by region, so it's worth reading this part closely.

Your chats with Meta AI

The notes at the bottom of Meta's Facebook Help Center articles on AI say three things. Meta uses your interactions with AIs to improve AI at Meta. If the AI can't answer your query, Meta shares the messages you send to AI, plus general information like your region, with select partners. And Meta AI uses your location and profile information, such as age, gender and interests, to personalize your interactions with it.

Personalized content and ads

In October 2025, Meta announced it would use your interactions with AI to personalize the content and ads you see, starting December 16, 2025. Its example: chat with Meta AI about hiking, and you might see hiking groups or ads for hiking boots. Meta set these limits in that post:

• Conversations about religious views, sexual orientation, political views, health, racial or ethnic origin, philosophical beliefs or trade union membership aren't used to show you ads.
• Signals are only shared across accounts you've added to the same Accounts Center. If your WhatsApp isn't in it, Meta AI chats there won't personalize your other Meta accounts.
• The change applies in "most regions," not everywhere.

Meta points to Ads Preferences and feed controls to adjust what you see. The announcement doesn't describe a setting that stops AI chats being used as a signal.

Training AI on your posts

Meta's Privacy Center page on generative AI lists "posts or photos and their captions" and your interactions with its AI features among its training sources. It says Meta doesn't use your private messages with friends and family "unless you or someone in the chat chooses to share those messages with our AIs." It also says people without an account may have their information processed, for example if they appear in someone else's photo.

The EU details come from Making AI Work Harder for Europeans, which Meta updated on March 27, 2026 to clarify that it may train on messages people choose to share with its AI features. The UK details come from Meta's UK announcement. Meta's Messenger Help Center also links to an objection form for people who don't want their information used for its generative AI models, without saying how it's handled in each country.

AI labels on images and video

Meta first labeled AI content "Made with AI," then changed it to "AI info" in July 2024 because photos with minor AI edits were getting the label. Its current Help Center article calls it an AI content label and explains how it works:

• Made with Meta's tools: content created or modified with Meta AI and shared directly may be labeled automatically. Some carries a visible "Imagined with AI" watermark.
• Made with other tools: content with industry-standard signals, such as C2PA metadata, showing it was created with AI gets a label.
• Only edited with AI: no label on the post itself. The details are in the post's options menu.

If you post, Meta requires a label on photorealistic video or realistic-sounding audio that was digitally generated or altered, and says there may be penalties if you skip it. Images don't require your label, but they're still labeled if Meta detects AI. Use the "Add AI label" toggle in the composer. If you post AI content often, you can also add an AI creator label to your profile.

Meta also admits that "not all AI content contains the information needed to identify it." An image without a label may still be AI-generated.

Meta's Help Center also warns that AI responses "may be inaccurate" and shouldn't be used for important decisions, so double-check anything that matters. If you're new to assistants in general, how to use AI is a plain-language starting point. And if you'd rather choose your own AI tools than rely on the ones built into your apps, Taku is a desktop workspace for finding and running AI apps and workflows other people have built, without setup or code. Taku is in Beta, and the Mac app is available now.

Key points

• Meta AI shows up in Facebook search, AI Mode, Messenger, the post and comment composers, and comment summaries.
• Meta's documentation describes per-feature controls, not one off switch.
• Comment summaries and AI titles are on by default. You can't turn off summaries on posts in groups.
• Meta uses AI interactions to improve its AI and, since December 16, 2025, to personalize content and ads in most regions, excluding sensitive topics from ads.
• Meta announced objection forms for AI training in the EU and UK. Check the Privacy Center for your region.
• AI labels depend on detected signals or disclosure, so an unlabeled image can still be AI-generated.

FAQ

How do I get rid of Meta AI on Facebook?

Meta's Help Center doesn't describe a way to remove it completely. You can remove comment summaries from your posts, turn them off for a Page, turn off AI-generated titles, disable a group's AI as an admin, and turn off message sharing in a chat. Most other features only run when you tap them.

Does Facebook use my posts to train AI?

Meta's Privacy Center lists posts, photos and captions, plus AI interactions, as training sources. In the EU and UK, Meta says it uses public content from adults and offered an objection form. It says it doesn't train on private messages unless someone in the chat shares them with its AI.

Does Meta use my Meta AI chats for ads?

In most regions, yes, since December 16, 2025. Meta says conversations about sensitive topics such as health, religion, politics and sexual orientation aren't used to show you ads.

What does the "AI info" label on Facebook mean?

Meta detected AI signals in the content, or the person who posted it disclosed AI use. Content only edited with AI shows the details in the post's menu instead. Meta's Help Center now calls it an AI content label.

Can I stop Meta AI from summarizing comments on my posts?

Yes for your own posts and Pages: remove the summary from a post, or turn off comment summaries in your Page's settings. For posts in Facebook groups, Meta says you can't turn them off.
