Two AI agents now offer to run your busywork, and they are built for very different people.
Meta launched Muse on September 8, 2026, and xAI launched Grok Bot in beta on August 11. Both work in the background, connect to your apps, and check with you before doing anything big. This guide compares them in plain words, so you can tell which one fits the way you work.
If you’re a physician on the fence about which AI agent to work with, this is written for you. Let’s talk more about it.

Muse AI vs. Grok Bot for Physicians
| Muse (Meta) | Grok Bot (xAI) | |
|---|---|---|
| Cost to start | Free, with a usage limit | Paid plan, from $30 a month (list price) |
| Where you use it | iPhone and Android app, muse.ai, WhatsApp | Desktop app, phone app, Slack, X chat |
| Best known for | One personal assistant for life and small business | A team of assistants, each with a job |
| Patient data (HIPAA) | No coverage stated | No coverage stated |
What they have in common
An AI agent is different from a regular chatbot. A chatbot answers a question and waits. An agent takes a job, works through the steps on its own computer in the cloud, and keeps going after you close the app. Both Muse and Grok Bot work this way. Both connect to tools like email, calendars, and accounting apps, and both are meant to ask before they send, buy, or delete anything.
Both companies also tell you to start small. Meta’s help pages suggest low-risk tasks first. xAI’s guides suggest starting with work where the Bot only prepares something for you to review.
Muse: one assistant for everyday life
Meta says anyone can use Muse with no technical skills, and that it is available in the US. You message it in the app, at muse.ai, or in WhatsApp.
It can handle email and calendar tasks, book travel, fill out forms, and track budgets.
Muse for Small Business adds connections to tools like QuickBooks, Slack, Zoom, Canva, and Shopify, plus your Facebook and Instagram business accounts.
Grok Bot: a team of assistants, each with a job
With Grok Bot, you create several named assistants, called Bots, and give each one a job.
xAI’s examples include a chief of staff that writes a daily digest of what needs your attention, an expense manager that matches receipts and flags missing information, and Bots for sales outreach and ad reports.
You can talk to your Bots in the desktop app on Mac, Windows, or Linux, in the phone app, in X chat, or in Slack, according to xAI’s docs. Bots can repeat a job on a schedule.
A feature called Teach a task lets a Bot learn from watching you do a browser workflow, though xAI says it is rolling out gradually. Grok Bot is built more for repeatable work and for teams than for personal errands.
Privacy and safety in plain words
Both agents get access to your accounts, so how each one protects them matters.
Meta says Muse runs on a private computer of its own, and a separate gatekeeper program must approve anything that leaves it. Meta says Muse cannot see your passwords or payment details, and an Activity log shows what it did. You can opt out of having your chats used for training. Meta’s research post adds that its staff are limited by policy but not blocked from seeing data when needed to run the service. A stricter version, Muse Confidential VM, is planned for later this year.
In October, security researchers found that pages shared from Muse could be located through public web records. Meta paused sharing, fixed the problem, and turned it back on October 22. Meta said it affected shared documents and images, not chats.
For Grok Bot, xAI’s security docs say all of your Bots share one cloud computer, along with its files and logins, so separate Bots are not a security wall. xAI’s FAQ says Grok Bot needs cloud storage, does not support Cursor’s Legacy Privacy Mode, and follows your Cursor account’s training settings. xAI also says Grok Bot picks the AI model for each task, which can include models from outside companies on a published list. If you share a Bot through a link, the link shows its setup, so remove secrets first.
On patient information, neither company says its agent is covered under HIPAA. None of the Muse pages reviewed mention HIPAA or a Business Associate Agreement, and xAI’s BAA request page is about its APIs. Keep patient information out of both, and check with your compliance team.

Which one should you pick?
Muse fits if you want to try an agent without paying first and spend most of your day on your phone or in WhatsApp. It suits a physician who wants help with everyday errands and a small business or side venture, like email, calendar, travel, budgets, and social media accounts.
Grok Bot fits if you are comfortable paying, work mainly on a computer, and want separate assistants with separate jobs, such as one that prepares a daily digest and another that checks expenses. It also suits people who already pay for Cursor, SuperGrok, or a Premium-or-higher X Subscription plan, and an office or business with staff that wants team seats for business-side work.
Skip both for now if you would need them for patient information, or if you are not ready to review what an agent does before it acts.
A physician with a side business who wants to test the idea at no cost might start with Muse. A physician who owns a practice and wants repeatable weekly admin jobs, like expense checks or a daily digest, might look at Grok Bot’s team plans. Either way, start with a task where the worst result is a bad draft.
Bottom line
Muse is the easier and cheaper way to try an AI agent. Grok Bot costs more and asks more of you, but it is built for repeatable jobs and teams. Both are new, both can make mistakes, and both change often, so check the current plans and settings before you connect anything.
