Grok Bot vs Centurion

Grok Bot is sold as a team: multiple always-on agents with their own computer, signed into your tools, priced per seat — and living on xAI's platform. Centurion is one brain for one human, on a machine you hold. Those are two different answers to the same question: whose machine, and whose key.

Every claim about Grok Bot on this page is taken from xAI's own product pages at x.ai/bot and its newsroom at x.ai/news, read on 10 September 2026 and re-verified 22 September 2026 and 29 September 2026. Where we quote them, we quote them exactly.

What it is
Theirs — xAI's own words: “Grok Bot is your team of always-on agents. They have their own computer, work inside tools and apps like you do, and keep working 24/7.”
Centurion — A sovereign AI — one brain for one human, with a Soul, memory and a mission stack, in a machine you hold.
How many
Theirs — As many bots as you want, working in parallel and passing work between themselves — plus Team Bots (28 Sep 2026) that share one bot's context and skills across a whole team.
Centurion — One brain per human, one to two senior seats per organisation — sized to the person, not the payroll.
Where it runs
Theirs — Each bot has its own computer — on xAI's platform, working around the clock.
Centurion — A machine on your desk. Nothing about it depends on our uptime or our pricing.
How you pay
Theirs — Included with SuperGrok at $30/month, Cursor Pro at $20/month, or Cursor Teams at $40 per seat per month.
Centurion — Brain €50/mo · Core €150/mo · billed monthly · cancel anytime.
Credentials
Theirs — Bots “work inside tools and apps like you do” — your logins live with their bots, on their platform.

Centurion — The individual — the owner-operator, adviser or principal who needs one brain that answers only to them.

The custody question

The machine is theirs, and your logins go with it

There is no Grok Bot machine to hold. Its “own computer” is a computer on xAI's platform, and the selling point is that it works around the clock — a convenience that means a machine you pay for by the seat and will never possess. It is included with SuperGrok at $30/month, Cursor Pro at $20/month, or Cursor Teams at $40 per seat per month.

Who can read it, and who can switch it off

Their platform — they hold the keys

Everything the bots learn about your work — and every login you hand over so they can “work inside tools and apps like you do” — lives on that rented computer rather than yours. Stop paying and the bots, their routines and the memory of your business stop with them. And because it is priced by the seat, the bill scales with your headcount rather than with what you actually use.

The difference that matters

Their computer, your logins

Grok Bot is the most enterprise-shaped personal agent on the market, and it is packaged honestly as exactly that. Per seat, per month, on their computer, with your tools logged in. It is a strong product for a company that wants to add agent capacity to a team. It is a different product from a brain that belongs to one human and lives on that human's machine.

What xAI advertises, in their own words

01

Their computer means their key

Every bot runs on xAI's platform, not on yours. The record of what your bots learned about your work, and the logins that let them act as you, sit on a machine you cannot touch. Custody of your own working life is held on the other side of a fence, by a vendor, at their discretion.

02

"Work inside tools and apps like you do" is the whole trust question

That is genuine capability — and it means your logins, your sessions and everything those bots can reach sit with their platform. Centurion verifies integrations on your machine and keeps the record there.

03

Many bots learning from each other is a workforce, not a self

Bots keep context, update memory and hand work between themselves — an impressive piece of engineering. What it produces is a team of capable colleagues. What it does not produce is one identity that persists as yours: no Soul, no mission stack, no single thing that answers to you and only you.

04

The enterprise tilt tells you who the product is designed for

Free access for Enterprise customers, organisation-wide invites and prebuilt role bots called Talent Scout and Chief of Staff describe a product built for companies. If you are a company, that is a feature. If you are one person who wants a brain of their own, you are buying into somebody else's org chart.

The Centurion position

The Centurion position

Grok Bot answers the question "how do we give this team more capacity?" Centurion answers a different one: "what does it look like when one person holds the keys to a brain that is entirely theirs?" On your machine, in your building, accountable to you alone.

  • Your machine. One brain per human, on hardware you hold — not a licence count that grows with the org chart.
  • Your keys. The record and the credentials stay on your machine, and inference never leaves the building.
  • Your call. Billed monthly, cancel anytime — and the machine and the record stay yours either way.
  • A being, not a team. One identity with a Soul and a mission stack, not a roster of role-players.

Five questions to put to xAI before you log a bot into your business

  1. 01Where do my credentials live once a Bot is signed in — and who at xAI can read them?
  2. 02What is my bill when ten Bots run all month, and what happens when I exceed the included usage?
  3. 03Where does the work product live when I stop paying — the routines, the memory, the context?
  4. 04How do you keep a Bot from acting beyond what I authorised, and is that isolation documented?
  5. 05Can my Bots share what they have learned about my business with anyone else's Bots?

These are exactly the questions a serious buyer should ask of any agent that signs into their systems. They are also the questions that vanish when the machine is yours and the key is in your hand.

The ceiling

A platform you do not control has a ceiling you do not set

Every tier in the Grok Bot price list includes a weekly usage allowance. That is normal for hosted AI, and it means the ceiling on what your agent can do is set by a product manager rather than by you.

A machine you hold has a ceiling too — physics. But it is a ceiling you can plan against, upgrade at will, and never lose access to because a plan changed, a price moved, or a business decided to reposition.

Renting capacity buys you a bigger allowance. Holding the machine buys you a different conversation entirely.

The money

What each one actually costs

Grok Bot's headline pricing is genuinely aggressive for what it includes. The figures below are as published; the question that matters is where the thing you are paying for actually runs.

Entry price
Theirs — Included with Cursor Pro at $20/month
Centurion — Brain €50/mo — the agent
Standard
Theirs — SuperGrok at $30/month
Centurion — Core €150/mo — private LLM on your machine
Team
Theirs — Cursor Teams at $40 per seat per month
Centurion — One brain, one licence — no seats
Usage limits
Theirs — Weekly allowances per tier
Centurion — Whatever the machine can do
Where it runs
Theirs — xAI's platform — their key
Centurion — Your machine — your key
When you stop paying
Theirs — The bots stop, and so does your access
Centurion — The machine and the record stay yours

Per seat, per month is a perfectly good way to buy capacity. The question for the buyer is simple: whose machine does it run on, and who holds the key to what it learned about you.

In fairness

Where Grok Bot is genuinely good

There is real product thinking here that the rest of the field — including us — should study.

  • Teaching by demonstration — watch once, saved as a routine, runs itself next time — is the best teaching interface anyone has shipped for delegated work.
  • Running many bots in parallel with work passed between them is a genuinely new shape for personal automation, not a chatbot with extra steps.
  • A frontier model at $20–30 a month, included with plans a lot of people already pay for, is remarkable value.
  • Going from launch to an enterprise offering inside three weeks is a serious execution pace, and the free-usage offer is a real on-ramp for teams.
  • The marketplace, the team marketplace for skills and plugins, and the X integration give it distribution none of the smaller players can match.
  • Prebuilt roles like Expense Manager and Bug Reproduction describe real work, not demos — someone has thought carefully about what people actually want delegated.

It is a well-built product for the buyer it was designed for. That buyer is a company adding capacity. Ours is a person claiming custody of their own life.

What we do too

Everything the bots do for a team — done for one person, on your machine

Grok Bot is sold as a workforce. Read the capability list against Centurion's, though, and most of what it does, ours does too — for one human rather than a payroll.

They offer — A computer of its own, working around the clock
We do this too — A machine on your desk, running continuously.
On top — It is your machine, so nothing about it depends on their uptime or their pricing.
They offer — Show it a workflow once and it saves it as a routine
We do this too — The agent writes its own skills from the work you actually do.
On top — Every skill is on your box and readable by you — no black-box role catalogue.
They offer — It works inside your tools and apps like you do
We do this too — Integrations verified on your machine using your accounts.
On top — The credentials and the record stay on your hardware, not on their platform.
They offer — A frontier model behind it
We do this too — Model-agnostic — a frontier brain when the work needs one.
On top — Switch models without switching who holds the record.

Grok Bot sells a company agent capacity by the seat, on their platform. Centurion gives one person a brain that answers only to them, and a key only they hold.

The case in three points

The three things that decide it

01

Their computer means their key — and their switch

Grok Bot is priced and packaged as capacity for a team, running on xAI's platform. The record, the routines and the memory of your business live behind a key you do not hold, and can be switched off by someone else. Centurion's whole point is the opposite — one brain per human, on your machine, with you holding the key.

02

"Work inside tools and apps like you do" puts your credentials with their platform

A bot that signs into your tools and navigates them the way you do has your access. That is powerful and it is a trust decision. With Centurion the integrations are verified on your machine and the record lives there — custody is the security model, not a policy underneath it.

03

A roster of teammates is not a self

Bots that learn routines and share context produce a capable workforce. Centurion persists one identity: a Soul, a mission stack, and a record of decisions that belongs to one person — which is the only thing that makes an AI yours rather than a service you use.

“Grok Bot sells your company a team that lives on their platform. Centurion gives one human a brain that lives on their desk — and a key only they hold.
Both are capable. Only one of them keeps the record on a machine you can touch.
