Meta AI is Meta's conversational AI assistant, available through a standalone app, the meta.ai website, and built directly into WhatsApp, Instagram, Facebook, and Messenger. Powered by Meta's latest in-house models, it handles open-ended chat, web-connected answers, document and image understanding, translation, and creative writing. A standout feature is full-duplex voice conversation, letting users talk back and forth with the assistant in a natural, human-like way while multitasking. Through its built-in Imagine tool, Meta AI generates and edits images directly inside a chat, where users can upload photos to remove objects, change backgrounds, or restyle visuals. New memory and personalization features let the assistant remember details from one-on-one conversations and tailor recommendations based on a user's Facebook and Instagram activity, with full control to view and delete stored memories. The standalone app also includes a Discover feed for browsing prompts and AI creations shared by the community, plus seamless continuity across mobile, desktop, and Ray-Ban Meta smart glasses. Meta AI is currently free to use with no subscription required, though Meta has begun testing optional paid tiers for heavier workloads and advanced capabilities. As one of the most widely distributed assistants in the world, it reaches hundreds of millions of users through the apps they already use every day.
