Grok Bot vs Microsoft 365 Copilot for a small business (Oct 2026)
Updated · by Rosh Perera
Microsoft 365 Copilot lives inside the Microsoft apps your team already uses: Outlook, Word, Excel and Teams. For small businesses, Microsoft sells Copilot Business as an add-on for organisations with up to 300 users on a Microsoft 365 Business Basic, Standard or Premium plan (Microsoft Learn: Copilot Business FAQ). Grok Bot gives you Bots with one job each that work across connected apps and a browser. If your business runs on Microsoft 365, Copilot works where your files already are. If you want standing Bots doing repeat jobs, compare Grok Bot. Try our free planner to pick the first job.

Who can buy it and how
Grok Bot: on The X Subscription, Premium is $30 a month, Super $100 and Ultra $200, each with weekly Grok Bot usage included; extra usage is billed on token cost (x.ai, checked 18 Oct 2026). Copilot Business: an add-on for up to 300 seats on Microsoft 365 Business Basic, Standard or Premium, sold on an annual commitment with monthly or annual billing; there's no month-to-month option (Microsoft Learn: Copilot Business FAQ). Check Microsoft's pricing page for the current per-user price and any promotions.
Where it works
Copilot works inside Microsoft 365 apps and follows the data policies you set for your tenant (Microsoft Learn). Grok Bot works from its desktop and phone apps on a shared cloud computer with its own browser and logins (x.ai, xAI's FAQ).
How you hand over work
Grok Bot: you make a Bot for one job and write its rules in plain words. Routines run on a schedule or start from events, and Bots keep working with your laptop closed on a shared cloud computer with its own browser (x.ai, Grok Bot 101). Copilot: you ask in the app you're in, and Microsoft offers agents within Microsoft 365; check Microsoft's docs for which agents your plan includes.
Approvals
Grok Bot: before sending, posting, buying or deleting, a Bot shows you the action and you choose Allow once, Always allow or Deny, and you can add Ask first rules in Settings, General, Auto-review (xAI's Approvals docs). In Copilot, drafts appear in your Microsoft apps for you to send; review anything that goes to customers.
Which fits
Pick Copilot if your team lives in Outlook, Word, Excel and Teams and wants AI help inside those apps. Pick Grok Bot if one owner wants Bots running repeat jobs on a schedule across mixed apps, including Google tools and websites. Annual commitment matters: test before you buy seats.
Copy-ready prompt
Test job for either tool (drafts only): Every weekday at 17:00, read today's meeting notes in [folder] and today's sent emails. For each meeting: a 4-line recap with agreed actions and owners, and a draft follow-up email to attendees. Rules: don't send anything; if an action has no owner, list it under "unassigned".
Works as a Grok Bot routine, a ChatGPT scheduled task or a Claude project instruction. Fill in the [brackets] first. It only writes drafts.

Setup steps
- Pick one real job you do every week, like a Monday list of overdue invoices.
- Write it in five lines: what to read, what to make, where to put it, what it must never do.
- Run it in the tool you already pay for, drafts only, for one week.
- Write down every fix you had to make.
- Only then try the other tool on the same job and compare the fixes, not the demos.
Keep these human
- Both tools can act in your accounts. Keep anything sent in your name, paid for or deleted on approval, in either one.
- Prices and plans here are list prices from the vendors' own pages on the dates shown. They change often, so check both before you pay.
- We're an independent site with no commission from either vendor. We haven't measured either tool on your work, so any time saved is an estimate.

FAQ
Who can buy Microsoft 365 Copilot Business?
Organisations with 300 or fewer users on Microsoft 365 Business Basic, Standard or Premium (Microsoft Learn).
Can I pay for Copilot Business monthly?
You can be billed monthly, but it's an annual commitment; Microsoft says there's no month-to-month agreement (Microsoft Learn).
Does Grok Bot work with Outlook?
Check our Grok Bot connectors list for current apps. Grok Bot can also use websites in its browser, though sites may ask for a fresh login.
Which is better for a one-person business?
Run one weekly job in each on drafts. A solo owner who doesn't use Microsoft 365 daily may get more from standing Bots; a Microsoft-based team may prefer Copilot.
