Meta AI

Meta AI is Facebook's free AI assistant powered by the Llama 4 model family — one of the most capable open-weight AI models available. Unlike most AI assistants that require a separate app or subscription, Meta AI is built directly into WhatsApp, Instagram, Messenger, and Facebook, meaning billions of people already have access without installing anything new.

The assistant handles a wide range of tasks: answering questions, drafting messages, generating images, summarizing content, and providing recommendations — all within the apps you already use daily. The WhatsApp integration is particularly seamless: start a conversation with Meta AI just like texting a contact, or mention @MetaAI in any group chat to bring it into the conversation.

Meta AI is completely free with no usage limits or subscription tiers, which makes it the most accessible AI assistant in the world by reach. The trade-off is privacy: Meta uses conversation data as part of its broader data ecosystem for advertising and model training. For casual, everyday use it is hard to beat the convenience, but users with sensitive queries may prefer a more privacy-focused alternative like Claude or Perplexity.
