On August 20, Elon Musk posted a three-word ad for his own company's newest product: "Try @Grok @Bot". Two tags, because the assistant is @grok and the agent is @bot, and neither alone points at the product he was advertising. When the CEO needs two tags to name one product, the confusion is not a you problem.
This is not sloppy branding. It is an unfinished merger showing through the seams: four companies, four brand names, one quarter to fuse them. Nobody has published a clean map, so here is one.
The nine things people mean when they say "Grok"
1. Grok, the model family. The weights and the API model IDs: grok-4.6, grok-4.5, grok-4.3. The only "Grok" that appears in your code.
2. Grok, the consumer assistant. The chat product at grok.com and inside the X app. What most non-technical people picture.
3. Grok Bot. The agent product launched August 11, 2026. The subject of this guide.
4. Grok Build. A terminal-based coding agent, CLI and TUI, launched May 2026. Different product, different surface, similar name.
5. The xAI API. api.x.ai/v1, console at console.x.ai. Own account, keys and bill.
6. Cursor. The IDE. Now a SpaceXAI subsidiary, and the thing Grok Bot is built on.
7. Cursor Origin. Agent-first git hosting, launched August 17 and 18, 2026, during a GitHub outage.
8. X. The social network, Grok embedded across it, its own subscription in X Premium.
9. The subscription matrix. A product in its own right, because working out what you may run takes longer than running it.
Two traps live in that list. First: grok-build-0.1 is a model, "Grok Build" is a CLI, and the API alias for Grok 4.5 is grok-build-latest. So grok-build-latest is not grok-build-0.1, and the wrong string in a config file silently swaps the model you thought you were paying for. Second: x.ai's own footer drops the prefix and lists Chat, Build, Imagine, Voice, Bot, Grokipedia. "Bot" and "Grok Bot" are one product, named two ways, on one page.
What actually gets you Grok Bot
Cursor Ultra, $200 a month, includes Grok Bot. The docs are unusually direct: "Access is included. No second subscription or Grok account link is required."
SuperGrok Heavy, $300 a month, grants a free Cursor Ultra seat, but only after you click "Link Grok Account". Skip the click and the seat never appears. A great way to pay $300 and conclude the product is broken.
Cursor Teams Premium is $120 per seat per month and also includes Grok Bot. The team seat is cheaper than the $200 individual seat for the same agent access. Cursor Pro at $20 gets Origin but not Grok Bot, which is where most pilot budgets quietly die.
One login? No. "Grok Bot uses your Cursor account. There is no separate Grok Bot login." But xAI also states the xAI account is different from the X account, linking is manual, one Cursor account to one Grok account. Money arrives on four rails: Cursor's web checkout, x.ai and grok.com, Apple in-app purchase for the iOS tier, and X Premium through X.
Lansing
"I think the Grok bot, Grok super heavy, cursor ultra, X premium subscription plans need to get packaged into one set of plans. Each app has its own subscription with tiers and discounts, including features from the other apps. It's really confusing at the moment."
Lansing owns the stock, holds an annual Cursor plan, and loves Grok Bot. A paying fan, not a hater.

"This is how we end up with another Adobe Creative Cloud clusterfuck."
Why it looks like this
The timeline explains almost all of it. SpaceX acquired xAI on February 2, 2026, all stock. It went public in June as NASDAQ: SPCX. The AI unit rebranded to SpaceXAI on July 6. SpaceX closed its $60B all-stock acquisition of Anysphere, the company behind Cursor, on August 14.
Grok Bot launched August 11. Three days before the deal that owns it closed. That explains the forensics: an Anysphere bundle ID, co.anysphere.sand, where "Sand" was Cursor's internal codename. A download from downloads.cursor.com. Gated behind a Cursor subscription, marketed on an x.ai page, documented on both docs.x.ai and cursor.com/help. A Cursor product wearing a Grok name, shipped before the paperwork closed.
The legal names show it too. x.ai's page title says SpaceXAI, its footer says © X.AI LLC, x.com's footer says © X Corp., and the Grok Bot App Store listing says © Anysphere, Inc.
The sharpest tell is not naming. Grok Bot competes directly with Cursor Cloud Agents, formerly Background Agents, which also run in isolated cloud VMs. Neither product's docs mention the other. No official comparison page exists. The only disambiguation in all of xAI's docs is one FAQ line: "It is not the same as Grok on grok.com or the Grok mobile apps."
Be fair. Two overlapping agent products with separate docs is what four brands merging in one quarter looks like from outside. Not stupidity. Integration debt, paid in public.

"@SpaceXAI really should fix this confusing product and feature naming."
What an operator should do about it
Buying for yourself: Cursor Ultra at $200. Do not buy SuperGrok Heavy to get Grok Bot. Buy that for the consumer assistant, and if you do, click "Link Grok Account" on day one.
Buying for two or more people: Teams Premium at $120 per seat beats the $200 tier. Check that before anyone expenses an Ultra seat.
Piloting on Pro at $20: you do not have Grok Bot. You have Origin. Fix the line item before you write the evaluation.
Building on the API: separate account, console and bill from every seat above. Pin exact model IDs, never aliases, and grep your repo for grok-build today.
Answer the lock-in question before you spend weeks on any of it. Two agent products in one company, both running isolated cloud VMs, will not both survive consolidation intact. Keep the durable parts, the context files, the instructions, the workflow definitions, in your own repo, not inside one vendor's surface. When the plans get repackaged, and Lansing is right that they will, the migration should cost an afternoon.
Part 2 goes back further: the two open-source projects that shipped persistent agents before Grok Bot existed, and what you trade to get the version that needs no setup.
Buy seats, not names.
