What it does well
What it does for a company
The short answerGrok Bot is the most team-ready of the new personal agents, and it is still in beta. What it doesn't give you is a company brain with a living file per client and access set fact by fact, a choice of AI, or a server of your own. If those matter, Brainstack is the better fit, at one price for the company instead of per seat.
What one person needs from an agent, and what a company needs on top. What we say about Grok Bot comes from its maker and the press, and we mark what isn't public.

A personal agent knows one person. Brainstack keeps one brain for the whole company and answers each person with only what their role allows, from the app or from their own AI.

Instead of one assistant for one person, each agent owns a job, works to its schedule and brings you the big calls. One tap to approve, from the channel you already use.

More than 100 apps. The company brain reads only what you connect, and each agent acts only in the tools you give it.
Gmail, Drive, Notion, your CRM. The brain builds a living file per client from them.
Give each person a role. That decides what they see, in the app and in their own AI.
Pick a role, set its schedule and what needs your approval. It starts on the next run.
Every plan includes the company brain, your own server and approvals. You pay your company's AI plan directly to Anthropic, OpenAI or Google, at their price.
It does, and they are solid. The difference is what sits under the agents. Brainstack keeps one company brain, a living file per client with sources, and decides what each person can see in it. It also runs on the AI your company chooses and on a server only your company uses.
Grok Bot for teams is $120 per seat per month, so 10 people pay $1,200. Brainstack Growth is $499 per month for up to 10 people and 10 agents, plus the AI plan your company pays to Anthropic, OpenAI or Google.
Not in Grok Bot: an automatic router picks xAI models. In Brainstack you connect your company's Claude, ChatGPT or Gemini plan.
No. It is built for a company's work: clients, invoices, inbox, sales and support. Each person can still ask the company brain from their own Claude or ChatGPT, and gets only what their role allows.
Starter is $99 a month, Growth $499 and Scale $999, for the whole company. On top, you pay your company's AI plan (Claude, ChatGPT or Gemini) directly to the provider. We add no margin. Custom is priced with you.
On a server only your company uses, in the US or Europe, with encrypted backups every 6 hours. Your AI provider processes what an agent or a person sends it, under the terms of your plan.
Not yet. What we do have: one server per customer, permissions per person, approvals before anything leaves, a record of what each agent did, and GDPR terms.
