About Grok

Grok is an AI assistant made by SpaceXAI. You can chat by text or voice, ask it to reason through a problem step by step, upload files and PDFs for analysis, and generate images and short video with Grok Imagine. Its search mode looks across the web and X live, so answers can reflect what is happening now.

Grok is free to try on the web and in the iOS and Android apps, and you can sign in with an X or email account. There are four paid tiers. SuperGrok Lite adds Expert mode, longer conversations and an app builder with one-tap deploy to the web. SuperGrok adds longer conversations still, high-definition video up to 30 seconds, longer voice conversations and Grok Bot. SuperGrok Plus adds 1080p video, much higher usage across Chat, Imagine, Voice and Build, and priority access at peak times. SuperGrok Heavy adds the highest usage, a larger team of agents that collaborate on hard problems, X Premium+ at no extra cost and dedicated support.

SpaceXAI also offers an API that gives developers the same models for text, vision, voice, images and video.

Our take

Good for
a general chat assistant, especially if you already pay for X.
Skip it if
you need published, predictable usage limits.
The catch
the free plan's caps are not published, and plans sold on their own and bundled with X are easy to confuse, so check which one you are buying.

Checked . Plans and limits change, so confirm them on the vendor's site before you buy.
