Grok Bot Handles Online Tasks Like Train Tickets and Subscriptions With Ease
It's the most autonomous AI agent on the market right now, alongside Meta's Muse. Grok Bot promises to automate and simplify everyday digital tasks. The agent, developed by SpaceXAI, has its own cloud-based machine and its own email address, so you don't have to be in front of your computer. We tested it on three use cases involving online booking and fully autonomous (or nearly so) purchasing—even on the most confusing sites (like SNCF's). Here's our feedback on how to get the most out of it.
How does Grok Bot work?
Grok Bot was created following SpaceXAI's acquisition of Cursor, finalized in August. According to leading industry analysts, it was mostly the Cursor teams who developed the agent's harness (the software environment that frames the model and provides its tools). The concept is very simple: Grok Bot runs with a main agent that has its own virtual machine in the cloud, complete with a dedicated browser. It operates independently on its machine. The main agent can then summon sub-agents for specific tasks, assigned either by the user or the main agent. Finally, users can connect the agent to dozens of third-party connectors (Google Drive, Notion, Gmail, 1Password, etc.). Everything is powered by the company's latest model: Grok 4.7, specifically trained on Grok Bot's harness. It's a fully integrated loop.
Grok Bot is available as a desktop app for PC and Mac, with a companion mobile app. You can also access your agent directly from Grok.com on the web (though the interface is much more minimalist). Since all tasks are performed entirely in a cloud-hosted virtual machine, they keep running even when your computer is turned off.
Since October 12, Grok Bot has been included in The X Subscription, the bundle that brings together Grok, Cursor, and X Premium. There are three plans that provide access to the agent:
- Premium at $30 per month, which gives reasonable but limited access to the agent.
- Super at $100 per month, offering 3.5 times more usage than Premium.
- Ultra at $200 per month, with 12 times the usage of Premium.
We tested the tool over several weeks with a SuperGrok subscription, equivalent to Premium ($30 per month). It's very straightforward: just send your prompt in natural language to your main bot, which handles everything autonomously and notifies you if it needs your help. You can then take control directly on the agent's computer—for example, to enter your credit card number or provide personal information the AI doesn't know.
Three everyday tasks put to the test
We tried Grok Bot on three real-life scenarios: buying a train ticket via SNCF Connect (yes, really), booking a vet appointment, and switching mobile phone carriers.
Booking a train ticket
The goal here is simple: book the cheapest possible round-trip train ticket between Avignon TGV and Marne-la-Vallée Chessy for a specific period. We asked our main Grok Bot agent in natural language:
Can you please book the following SNCF tickets: - Outbound: Friday, November 6 at 7:00 p.m., Avignon TGV - Marne-la-Vallée–Chessy - Return: Sunday, November 8, the cheapest trip after 12:00 p.m., Marne-la-Vallée–Chessy - Avignon TGV If it's cheaper from/to Nîmes, choose Nîmes. Passenger: my mother-in-law, Firstname Lastname, born xx/xx/xxxx. Let me know before finalizing.
The agent performed flawlessly, searching the SNCF Connect site (notoriously difficult for humans). It ultimately suggested checking out on the Ouigo site. The agent found the trains, we approved its choices, it filled out all the required forms, and then handed control back to us for payment. The agent compared prices from and to Nîmes, as requested, before settling on Avignon TGV.
The experience went perfectly, without a hitch, and the bot only handed control back for sensitive operations—choosing tickets and making payment. That's exactly what you want from a good commerce agent.
Booking a vet appointment
Your reporter, proud owner of a rabbit—a NAC (nouvel animal de compagnie, or new pet)—needed to book a check-up at the vet. More and more clinics now offer online booking for pets (similar to Doctolib). Once again, we tested Grok Bot's autonomy. We simply asked our main Grok Bot agent:
Book me an appointment at the Val d'Europe veterinary clinic with a vet specializing in NACs, for my rabbit who has a small black mark behind its ear. Reason: rabbit, small black mark behind the ear.
The agent got started but quickly hit a roadblock with the online booking manager, Pilepoils. It handed control back to us for login. Once logged in, the agent found available slots and suggested them to us. We accepted a slot, and Grok finalized the booking online without further input. Again, the agent strikes the right balance between autonomy, trust, and human validation—that's its real strength.
Switching mobile carriers
This is a time-consuming, low-value task for anyone who values their time: switching mobile phone carriers. Whether to get a better deal or improved services, regularly changing carriers is a smart move. Grok Bot can help. We let Grok Bot handle the entire process of subscribing and migrating a mobile contract from Bouygues to Sosh. To do this, we gave the agent the following prompt:
Sign me up for the following Sosh plan: https://shop.sosh.fr/mobile/forfait-voyage-200go-5g, with the number 06 XX XX XX XX, creating a new Orange account. Before starting, list all the information you need (identity, address, email, payment, RIO code if it's a number transfer, etc.) and ask me for everything at once.
The agent then asked us for all the information required to proceed. We provided everything, including our IBAN (it's already leaked online, so giving it to an AI agent isn't any riskier). Once it had the information, it filled out all the subscription forms. It only stopped and asked us to take over for two steps: providing the RIO (the operator identity statement, the code needed to keep your number when switching carriers) and the final account creation validation, which was blocked by a captcha at Orange (a real issue as agent-based commerce grows!). Orange isn't alone: in the US, Amazon has blocked Meta's Muse agent since September, and several banks now prevent AI agents from moving clients' money. E-commerce sites, designed to keep out bots, will need to learn to distinguish between a client-authorized agent and a malicious script.
Once all the steps were completed, Grok Bot let us know the order was confirmed. Thirty minutes saved, just like that. There was one major downside, though: in its summary, the agent sent us the Orange account password it had just created, in plain text in the conversation.
Simple instructions, adjustable security
If you want to try Grok Bot, we recommend starting with simple instructions that clearly describe the agent's goal and the means to achieve it (personal information, etc.). The security policy can then be set in one or two sentences. For example:
Goal: {{what I want to achieve, e.g. book a table for 4 on Saturday night around 8 p.m. at an Italian restaurant in Lyon, max $40 per person}}. Information: {{name, email, phone, address, relevant preferences}}. If you're missing anything, list everything you need and ask me for it all at once before starting. Process: do your research, then suggest 2 or 3 options with their prices. Wait for my approval before booking or ordering. Once the action is done, check that it's confirmed (email, reservation number) and give me a summary. Security: hand control back to me for any payment, banking entry, or final validation. Don't send any messages or delete anything without my approval.
You can then reply to the agent as it works to guide it more precisely or provide additional information, and take over if needed.
Grok Bot's real strength—and what's driving its adoption—is its seamless user experience. In the prompt, the agent lets users decide exactly which actions to delegate. When nothing is specified, the default security mode only hands control back at critical steps. That's what sets a truly usable AI agent apart from a prototype that's too locked down (as Operator from OpenAI or Comet from Perplexity have been). The price, which is relatively reasonable, creates a real opportunity for users who want to delegate low-value tasks to a simple AI agent. It's also one of the few proprietary agents with this level of autonomy—Muse, for example, isn't available in the EU.
