Grok Build Mode Lets SuperGrok Heavy Subscribers Build and Host Apps From a Chat Prompt
Describe an idea and Grok writes the code, shows a live preview in the chat, and publishes it to a grok.me link or custom domain - no install required.
Grok Build Mode launched today in Early Beta. Available to SuperGrok Heavy subscribers on grok.com, iOS, and Android, it turns a text description into a working app, website, game, or interactive dashboard - and publishes the result to a shareable grok.me link or a custom domain. Users never need to install anything, touch the code, or configure a build environment unless they want to.
Grok Builds a Live Preview in the Chat and Publishes It to a Link
Building starts with a text description. Grok writes the code, renders a live preview inside the chat window, and keeps iterating with each follow-up message - users can change the layout, add features, restyle anything, and keep refining until it looks right. Publishing sends the result to a grok.me subdomain or to a custom domain the user already owns, at which point anyone with the link can open it.
Websites, Working Apps, Games, and Live Dashboards
Websites cover landing pages, portfolios, and business sites - anything that would normally route through a web developer. Apps carry real state and logic: planners, trackers, calculators, simulations, and internal utilities that persist between sessions. Games run in 3D inside the browser; xAI showed a physics sandbox with sliders for gravity and friction, and a 16-step drum sequencer that turns mic input into a beat pattern. Dashboards go furthest - a connector feature pulls in live business data and turns it into filterable charts that anyone on the team can share without a BI tool or a separate engineer.
SuperGrok Heavy Is the Only Tier That Gets It
Access costs $300 a month. SuperGrok Heavy is the only plan that includes Grok Build Mode, available today from the mode switcher on grok.com and in the iOS and Android apps. xAI marked the release Early Beta and has not set a date for a wider rollout. Build Mode joins the same tier that already unlocks the company's most capable Grok 4 Heavy model.
Grok Build Mode's clearest competition is Claude Artifacts. ChatGPT's canvas and Google's experimental app-building tools target the same use case: prompt in, runnable result out. Grok adds grok.me subdomain hosting and custom domain publishing as differentiators - every built project gets a live public URL without touching a deployment tool, which Claude Artifacts currently does not offer. Whether SuperGrok Heavy subscribers - who already pay $300 a month - actually reach for Build Mode instead of Cursor or GitHub Copilot is what xAI's usage data will reveal.
