Microsoft Copilot Review for SMBs

ai assistant tool · $30 per user/month for Copilot for M365 / free Bing Copilot

Microsoft Copilot is Microsoft's bet on embedding AI across its ecosystem—Office documents, Windows, and Bing search. If you're already paying for Microsoft 365, the enterprise version ($30/user/month) layers AI on top of your existing data. The free Bing version is a browser-based chatbot that competes with ChatGPT but ties directly to web search.

What it does

Copilot for M365 reads your Word docs, Excel sheets, PowerPoint decks, and Outlook emails to summarize, draft, and edit content without leaving those apps. It also appears in Windows as a sidebar and in Bing as a conversational search engine. The M365 version handles document-specific tasks; the free Bing version is general-purpose chat with live web access. Neither requires you to copy-paste text into a separate tool—it works in-app.

Who it's for

✓ Ideal user

Teams already deep in Microsoft 365 who want AI-powered writing and summarization without switching between tools. You're willing to pay per-seat licensing for tight Office integration.

✗ Not for

Shops built on Google Workspace, Slack, or non-Microsoft stacks will find the integration friction not worth the cost. Single founders or freelancers will get more mileage from free ChatGPT or Claude.

Typical team size

15–500 employees (M365 adoption curve); solo users can use free Bing Copilot.

Typical industries

Professional services (legal, consulting, accounting)Financial services and bankingCorporate operations and administrationHigher education

Pros

✓ Deep Office integration eliminates context-switching. You don't open a new tab or copy text—Copilot reads your Word doc, Excel model, or email thread directly and offers drafts or summaries inline.

✓ Your data stays within Microsoft's ecosystem (M365 version), which matters for regulated industries like finance and healthcare that need data residency and audit trails.

✓ Live web search (Bing Copilot) gives you current pricing, news, or competitor moves without hallucinations about outdated facts; ChatGPT's free tier has no real-time data.

✓ No separate subscription for light users. If you're already on Microsoft 365, the free Bing version is available now; Copilot Pro ($20/month) sits between free Bing and enterprise pricing.

Cons

✗ The enterprise version ($30/user/month) is expensive at scale. A 50-person team pays $18,000 annually just for AI; ChatGPT Team costs $30/month flat for unlimited users on a shared account.

✗ Document AI quality is inconsistent. Summarizing a 20-page report works well; drafting complex financial models or legal analysis from scratch is slower and less reliable than a specialist tool like Spellbook for contracts.

✗ Limited to Microsoft products. If your workflow lives in Google Docs, Notion, Slack, or Figma, Copilot can't touch it—you're stuck copying text out and pasting results back in.

Pricing breakdown

$0 (Bing Copilot) or $30/user/month (Copilot for M365)

Copilot for M365 is $30 per user per month on top of your M365 subscription (Microsoft 365 Business Standard or higher required). Free Bing Copilot is available to everyone; Copilot Pro ($20/month) sits in the middle for power users.

Where it gets expensive

Per-seat licensing adds up fast at 50+ employees ($18,000+ annually). If you need it for the entire org, you'll pay more than a team ChatGPT subscription.

Alternatives worth considering

ChatGPT
ai assistant
General-purpose AI assistant for drafting replies, brainstorming, and rewriting text from prompts.
Standalone AI chat with 200M+ users, better instruction-following, and a flat $20/month Team plan for unlimited org users. No Microsoft lock-in, but no native Office integration either.
Claude
ai assistant
Chat-style assistant for longer documents, nuanced rewrite tasks, and step-by-step planning.
Stronger reasoning for long documents and financial analysis, plus 200K context window (reads entire reports in one go). Requires pasting content, but outperforms Copilot on complex tasks.
GitHub Copilot
ai coding
Developer-focused coding assistant for engineering teams writing and reviewing software faster.
If your team writes code, GitHub Copilot ($10/month per developer) integrates into IDEs and handles technical documentation better than Copilot; can also draft emails and docs as a general tool.

Verdict

Copilot for M365 is a convenience layer, not a game-changer. It shines if you're a Microsoft shop and want AI help without leaving Word or Excel—but you're paying a premium for integration you may not use daily. Free Bing Copilot is worth testing; the $30/month enterprise version is only justified if at least 40–50% of your team will use it regularly for document work.

Worth it when

Your team is already on Microsoft 365 Enterprise, spends 10+ hours weekly in Word/Excel, and has budget for per-seat AI licensing. Legal, accounting, or consulting firms with compliance requirements benefit from data staying within Microsoft.

Skip when

You're on Google Workspace, Notion, or Slack; you need AI for specialized tasks (coding, design, video); or your budget won't support $30/user/month across your team. Free ChatGPT or Claude will serve you better.

FAQ

Do I need Microsoft 365 to use Copilot?▼

For Copilot for M365, yes—you need Business Standard ($12.50/user/month) or higher, plus the $30 Copilot add-on. Free Bing Copilot works in any browser with no subscription.

Can Copilot access my company data without uploading it to the cloud?▼

Copilot for M365 processes your documents within Microsoft's infrastructure but doesn't train on your data or share it with Bing. If you need strict air-gapped AI, this won't work; you'd need an on-premises solution.

How does it compare to ChatGPT or Claude for writing quality?▼

ChatGPT and Claude are better general-purpose writers, especially for creative or technical work. Copilot excels at summarizing and editing *existing* documents but is slower at generating long-form drafts from scratch.

Can I use just the free Bing version and skip the $30 enterprise tier?▼

Yes, if you don't need Office integration and don't mind pasting text into a browser. Free Bing Copilot has web access and works fine for research, brainstorming, and light writing—it's honest competition for free ChatGPT.
