What is Grok Bot? The SpaceXSI agent app and the @grok bot on X, explained

“Grok Bot” means two things right now. Officially, it’s Grok Bot, an app from SpaceXSI (the company formerly called xAI) launched in August 2026: you create AI agents called Bots that sign in to your apps and do work for you, such as shopping, email, expense reports and now phone calls. Informally, many people still use “Grok bot” for @grok on X, the chatbot account that replies when you tag it under a post. They’re different products with different prices. This guide covers both.

Grok Bot, the agent app

Grok Bot is a separate app from the Grok chatbot. Instead of chatting, you give each Bot a name and a job, and it works on its own cloud computer with a browser, files and a terminal. It signs in to the tools you connect, runs routines on a schedule or when something happens, and asks for your approval before sensitive actions. Because the work happens in the cloud, it keeps going when your laptop is closed.

A few things set it apart from a chatbot:

• It acts, not just answers. A Bot can fill in forms, compare prices, place orders and send messages.
• It speaks first. A Bot can send you a morning briefing and follow up on its own instead of waiting for a prompt (overview).
• You can run several Bots. They work in parallel and can pass work to each other.
• It learns by watching. You can record a demonstration of up to 10 minutes and the Bot learns the task.
• It makes calls. Since early November, Bots can phone US businesses for you. Each call must say it comes from a virtual assistant, and you approve the final terms (Teslarati).
• You can tag it on X. Tagging @bot in a post hands that post to your Bot as a task, for example to summarize a thread (Grok Bot FAQ). Note that’s @bot, not @grok. Chatting with your Bots in X Chat is still rolling out gradually; today you talk to them in the apps or in Slack.

@grok, the reply bot on X

@grok is the X account for SpaceXSI’s Grok chatbot. You tag it under a post (“@grok is this true?”) and it replies publicly in the thread. Before August 2026, this is what almost everyone meant by “Grok bot”.

Two things changed this year. Since March 12, 2026, summoning @grok in replies has been limited to paying X subscribers; free users can still chat with Grok privately in the Grok tab on X or at grok.com (Unilad). Then in October, X Premium was folded into The X Subscription, so the plan names have changed since that report.

If you just want to ask Grok questions, you don’t need Grok Bot. The Grok chatbot is free to start. This site covers assistants that act for you, so it doesn’t review the chatbot.

Why everyone is talking about Grok Bot now

Several things have kept Grok Bot in the news since launch, in order:

1. Launch and fast rollout. Grok Bot launched in beta on August 11, 2026 for SuperGrok and Cursor subscribers, then spread to Windows, Linux and Android, teams and enterprises.
2. Tesla. It has been in Tesla cars since September 22 (Teslarati).
3. The X Subscription. On October 12, SpaceXSI bundled Grok, Grok Bot, Cursor and X Premium into one subscription. Elon Musk called Grok Bot “the fastest growth of a product that I’ve ever seen in my life” (TechCrunch).
4. Usage limits. Over Halloween weekend, users found their weekly allowance used up, and Musk said “the cost of serving Grok Bot was unsustainably high relative to revenue” (TechCrunch, same article).
5. Phone calls. In early November, a creator showed a Bot negotiating a cheaper Comcast plan over a 25-minute call (Teslarati).

How to get Grok Bot

1. Subscribe to Premium or higher on The X Subscription at x.ai/pricing. The $8 Plus plan and the free plan don’t include Grok Bot. Legacy paid Cursor plans still include it, and older SuperGrok and X Premium+ plans can get it by linking to a Cursor account (FAQ).
2. Download the app. Grok Bot runs on macOS, Windows, Linux, iPhone, iPad and Android. There’s no browser version.
3. Create a Bot, give it a job and connect the accounts it needs. Start with approvals on.

What it costs

There’s no free plan and no standalone price. The cheapest way in is Premium at $30 a month, which also includes Grok chat, Cursor and X Premium features. Super ($100) and Ultra ($200) give more usage.

The catch is that usage comes from one weekly pool shared with Grok and Cursor, SpaceXSI doesn’t publish how much work it covers, and it was tightened in November. Past the pool, you pay from prepaid credit, and spending caps don’t stop a Bot mid-run (FAQ).

What people like

• It does the boring web work. Users and SpaceXSI highlight shopping, travel, subscription cleanup and inbox chores (changelog, JDN).
• It keeps working when you’re away, because it runs on its own cloud computer.
• It’s everywhere. Apps for every desktop and phone, plus Slack and Tesla cars.
• The phone calls. Negotiating a bill or booking an appointment by phone is the kind of task people actually hate doing.

What people complain about

• Limits. Users on X reported their usage jumping from as low as 50% to 100% without doing more (TechCrunch), and nobody knows the new limits.
• Price. $30 a month minimum, with no free plan.
• Blocked sites. Amazon has refused orders from Grok Bot since at least October 10 (Teslarati).
• No model choice. Grok Bot picks the model and doesn’t say which one it used.
• Shared access. All Bots on an account share one computer and logins, so separate Bots aren’t a security boundary.

For @grok on X, the complaints are different: the paywall on replies, and the chatbot’s history of offensive replies, including sexualized images it generated on X around New Year 2026 (CNBC).

Grok Bot alternatives

• OpenClaw and Hermes Agent are free and open source and run on your own computer with the model you choose, answering in WhatsApp, Telegram, Slack and more. Best for technical users who want control.
