xAI and Cursor Launch Grok Bot, an Agentic AI App for Mac and iPhone

xAI, operating under the name SpaceXAI amid its ongoing merger with Cursor, has launched Grok Bot, a new AI agent application for Mac and iPhone. The app entered beta on August 11, 2026, with desktop versions also available for Windows and Linux. An Android release is listed as coming soon.

According to SpaceXAI's announcement, Grok Bot is designed to function as "AI teammates you can give real work to." Each Bot operates on its own dedicated computer instance and signs into a user's existing accounts and services — including inboxes and other work tools — to carry out tasks. The company claims Bots can complete jobs end to end, surfacing only when human approval is required.

Users interact with a Bot by messaging it "like a colleague," according to xAI. The company also claims the agent retains memory across conversations, learns user preferences over time, and improves performance with continued use. No independent benchmarks or verification of these capabilities have been published.

At launch on August 11, access was restricted to SuperGrok Heavy subscribers, Cursor Ultra subscribers, and Cursor Teams Premium subscribers — the highest-tier plans across both products. Ten days later, on August 21, SpaceXAI expanded access. SuperGrok Plus, Cursor Pro+, and Cursor Teams subscribers now have access to Grok Bot. The company also introduced a free trial with limited usage for users outside those subscription tiers.

Pricing for the underlying subscription tiers was not disclosed in the announcement, nor was any per-task or per-token cost associated with running Bots. The product is positioned as a bundled feature of existing SuperGrok and Cursor plans rather than a standalone paid product.

What this means

Grok Bot arrives as the clearest signal yet of how the xAI-Cursor combination intends to compete in the agentic AI market. Rather than shipping a new foundation model, the companies are packaging existing Grok capabilities into a consumer- and developer-facing agent product that operates across a user's real accounts and tools — a category OpenAI, Anthropic, and Google have all been racing to define with their own computer-use and agent offerings.

The rapid loosening of access tiers within 10 days — from the most expensive SuperGrok Heavy and Cursor Ultra plans down to Plus and Pro+ tiers, plus a free trial — suggests either strong initial demand or an aggressive push for adoption ahead of the formal SpaceXAI-Cursor merger closing. Restricting a beta to top-paying subscribers first is a common strategy to manage compute costs on an expensive, still-unproven product before opening it more broadly.

The bigger open question is reliability. An agent that logs into a user's inbox and other services and acts autonomously until it needs approval raises obvious concerns around error correction, security, and scope of access — none of which xAI has addressed with technical detail or third-party audits in this announcement. Until independent users and security researchers stress-test Grok Bot's autonomy claims, the product should be treated as an early beta rather than a proven work-delegation tool.
