What it is
Grok is a chat assistant that answers questions, writes code, creates images and pulls real-time answers from the web and from posts on X. It runs at grok.com, in iOS and Android apps and inside X. Its maker, xAI, merged into SpaceX in February 2026, and Grok's site now names the company SpaceXSI.
It suits people who want current information and are comfortable with answers shaped by X content. There is a free tier with usage limits; SuperGrok subscriptions give much more access to the premium models and early access to new features. Check the plans page for current prices, which change often and include promotions.
Best for
- Following news and conversations as they happen on X
