Grok is xAI's AI assistant, free to use on the web and in its iOS and Android apps, and upgraded through several SuperGrok tiers and a Business plan. What decides whether it suits you is whether you need the higher usage limits on SuperGrok and SuperGrok Plus, since core chat, image generation and the Grok Build coding agent are already included on the free plan.
What is Grok?
Grok is made by xAI, a US company that has joined SpaceX and whose website now brands itself SpaceXAI. Grok runs on the web at grok.com and in mobile apps for iOS and Android, and one account keeps your conversations, settings and subscription in sync across them.
What you can do with Grok
Grok's app runs on the Grok 4.6 model. Only xAI's own models are offered inside the chat app.
Real-time web and X search is included, at a limited level on the free plan and in full on paid plans.
Grok accepts uploaded files including PDFs, images, spreadsheets, code and audio for analysis and summarization. Image generation, part of Grok's Imagine feature, is included even on the free plan, and video generation under Imagine starts at SuperGrok Lite. Voice mode is also included on the free plan.
Grok Build is a coding agent with a plan mode, for proposing a structured approach before writing code, and subagents that run in parallel for testing and research; sandboxed and terminal execution run the code it writes. Grok Build is available even on the free plan. SuperGrok and above add Grok Bot, which runs AI teammates on a persistent cloud computer.
Through its connectors, Grok can read from Google Drive, Gmail, Google Calendar, Outlook Mail, Outlook Calendar, SharePoint, OneDrive, Microsoft Teams and Salesforce, and it supports custom MCP tunneling for connecting other tools. Projects are available on grok.com.
Working with other people
The Business plan adds team seat management and consolidated billing. xAI also sells a developer API as a separate product with its own console. The app itself runs on the web and in the iOS and Android apps.
Grok pricing: what each plan gives
The Free plan costs nothing and already includes core chat, image generation through Imagine, voice mode and the Grok Build coding agent. Web and X search is limited on Free, and paid tiers raise the usage limits.
SuperGrok Lite costs $10 a month and SuperGrok costs $30 a month; SuperGrok Plus costs $100 a month and SuperGrok Heavy costs $300 a month. Video generation starts at SuperGrok Lite, and Grok Bot at SuperGrok.
Business costs $30 a month per user and adds team seat management and consolidated billing. Single sign-on is only on Enterprise, which is priced on request.
Privacy and security
On grok.com, you can choose whether your content is used to train Grok, in Settings, Data, and Improve the Model. Business and Enterprise plans include no training as their standard setting, rather than requiring you to opt out.
Grok is SOC 2 Type I and Type II compliant on every plan, including Free. It includes privacy tools meant to help organizations comply with regulations including HIPAA, the GDPR and the CCPA. Single sign-on is available on the Enterprise plan.
Support runs through the in-product issue report, email and a Discord community.
Who Grok suits
Grok suits people who want a free AI assistant that already includes image generation, voice mode and a coding agent rather than holding them back for a paid tier. It also suits small and medium teams that want seat management and consolidated billing on the Business plan.
It suits less well anyone who wants no training on their content without opting out on a consumer plan, since the default no-training setting is limited to Business and Enterprise. It also suits less well companies that need single sign-on, which is only on Enterprise.
