Meta AI is Meta's free AI assistant and answer engine, built into Facebook, Instagram, WhatsApp, and Messenger as well as the standalone meta.ai website, that answers questions using Meta's Llama models combined with real-time information pulled from the web. It is aimed at anyone already using Meta's apps who wants a built-in AI assistant at no cost, rather than a paid, standalone research tool.
What it is
Meta AI is described by Meta as "the most intelligent AI assistant you can use for free." It runs inside the apps most people already have open — Facebook, Instagram, WhatsApp, Messenger — as well as on a dedicated meta.ai website, so users don't need to install a separate app or sign up for a new paid product to get AI-generated answers.
How it answers and cites sources
Meta AI is built on Meta's own Llama 4 model. For up-to-date information, it draws on real-time web search results: independent reporting documents that "Meta's AI assistant now integrates real-time search results from both Google and Bing," meaning Meta AI's web grounding runs through partner search indexes rather than a crawler Meta operates itself. Meta's own announcement frames this as letting users "access real-time information from across the web without having to bounce between apps." The publicly available facts do not document a specific inline-citation or footnote format the way some competing answer engines do, so it is not confirmed whether Meta AI shows a structured, clickable source list for every answer.
Pricing and access
Meta AI is free. Meta states plainly that it is "the most intelligent AI assistant you can use for free," with no paid tier documented for the assistant itself. It is available in a dozen languages across 43 countries, per Meta's own announcement, making it one of the more widely accessible free answer engines by language coverage.
Privacy and data use
Meta AI trains on user data by default: Meta's privacy center states that it draws "from publicly available and licensed sources, as well as information people have shared on Meta Products and interactions with features that are part of AI at Meta" to build its generative AI models. Meta does not present Meta AI as a GDPR-certified product in the material reviewed here, so users in the EU who are concerned about data used for AI training should review Meta's privacy center and in-app controls before relying on it for sensitive queries.
Who it's for
Meta AI fits people who already live inside Facebook, Instagram, WhatsApp, or Messenger and want quick, free, real-time-grounded answers without leaving those apps or paying for a subscription. Because it is free with broad language support, it also works as a low-friction way to try an AI answer engine, though its lack of a documented inline-citation format and its data-training-by-default approach mean it may be less suited to work that requires strict source traceability or strong data-privacy guarantees.
