Grok is an AI assistant made by xAI. You can use it from a menu inside X (formerly Twitter), on the website grok.com, and in apps for iPhone and Android. When you ask a question, it decides on its own whether to search public X posts or the web right then. It is like a guide who always watches the town square notice board: quick with new topics, but also reading whatever rumors are pinned there.
Watch out The X Help Center says Grok may confidently give incorrect information and asks you to check it yourself, and not to share personal or confidential data. Chats on X may be used for training; if you do not want that, turn it off in your privacy settings. On grok.com, if you use it without logging in, your input is treated as usable for training.
