Grok
Grok is xAI’s AI assistant for chat, live web and X search, reasoning, coding help, voice, and image or short video generation.
About this tool
Grok is the AI assistant developed by xAI, available on grok.com and in iOS and Android apps. It handles everyday writing, research summaries and coding questions, explains its reasoning step by step, and keeps memory across chats if you allow it. Its site now presents the product under the SpaceXSI name.
Two traits set it apart from other assistants. Search covers both the web and posts on X in real time, so answers can reflect breaking news and trends, with citations to the sources used. The Imagine features generate images and short videos from text or reference photos in the same conversation. A paid SuperGrok tier raises limits and adds a multi-agent mode, and developers can use the same models through the xAI API.
What you can do
Live web and X search
Grok searches the web and X while answering, cites the sources it relied on and lets you follow up to dig deeper into a topic.
Multi-agent reasoning
On SuperGrok, several agents can work on parts of a hard question in parallel and show their reasoning before merging a single answer.
Image and video generation
Grok Imagine creates and edits images and produces short clips, which xAI lists at up to 15 seconds, without leaving the chat.
Voice and file analysis
You can talk to Grok in natural voice conversations, upload PDFs and documents for summaries, and ask it to read screenshots or diagrams.
Who is it for?
- A journalist follows a breaking story with answers that include recent posts on X.
- A marketer drafts copy and generates a matching illustration in one conversation.
- A developer prototypes a feature with xAI’s models through the API.
Before you choose
Content from X and the live web can be unverified or fast-changing; open the cited sources before relying on an answer.
Review the privacy settings for memory and conversation sharing, since shared threads can be opened by anyone with the link.
