Copilot vs Gemini (2026): Which Work Assistant to Pay For

Short answer: pick the assistant that comes with the suite you already pay for. Copilot runs inside Word, Excel, PowerPoint, Outlook and Teams. Gemini runs inside Gmail, Docs, Sheets and Meet. On list prices, Google's Business Standard with Gemini costs $14.00 a user a month billed monthly, against $28.20 for Microsoft 365 Business Standard with Copilot on the same billing.

Toolradar data: our Microsoft 365 integration list names 17 AI assistants as of October 2026. That count covers one ecosystem only, so it does not rank the two suites against each other.

Both products sit inside a suite. That means the question is less about which model is smarter and more about the apps your team opens all day, and what each vendor charges for AI on top of a seat. This page compares the two work suites, not the chatbots. For the chatbot-only angle, read Copilot vs ChatGPT, Gemini vs ChatGPT, Claude vs ChatGPT or Perplexity vs ChatGPT.

The two products in brief

Microsoft 365 Copilot is Microsoft's AI assistant built into its office apps. Gemini is the AI inside Google Workspace, included in Google's business plans and also sold to individuals as a personal Google AI plan. The two vendors license the feature differently, and that difference drives most of the cost.

What each assistant does in your apps

Microsoft's Copilot overview, updated October 1, 2026, lists what the assistant does inside each app. In Word, you draft, rewrite and summarize documents. In Excel, it analyzes data, generates insights, creates formulas and builds visuals. In PowerPoint, it creates decks from a prompt or existing content, summarizes them and edits them, including adding images and applying deck-wide formatting. In Outlook, it drafts emails, summarizes threads and offers coaching on clarity, sentiment and tone. In Teams, it summarizes and transcribes meetings and captures action items. OneNote and Forms get drafting help too.

Google's Workspace AI page, checked October 10, 2026, lists the Gemini features for each app. In Gmail, it summarizes threads and drafts emails. In Docs, it writes first drafts that match your tone. In Sheets, it builds spreadsheets and fills tables from a natural language prompt. In Slides, it adds editable slides to existing decks. In Drive, it helps find, summarize and synthesize information across your files. In Meet, it takes notes during the call. Vids helps teams make video.

On the core office work, the two lists are close. Both cover drafting, summarizing, spreadsheets, decks and meeting notes. The real difference is where the work happens. If your team works mostly in Outlook and Excel, Copilot is the one you can use without leaving the app. If it works mostly in Gmail and Docs, the same logic points to Gemini.

What it costs for 25 seats

Microsoft and Google price AI differently. Microsoft sells Copilot as an add-on to a Business plan or as a bundle with Business Standard and Business Premium. Google includes Gemini in its Business plans, so the AI is part of the plan price. The table uses monthly list prices, and it shows yearly prices where the vendor prints them. The arithmetic is seats x 12 months x monthly price, shown once.

Prices come from Microsoft's Copilot business pricing page and Google's Workspace pricing page, both verified on the vendor pages in October 2026.

Two notes on the table. The add-on row is Copilot on top of a Business plan you already pay for. The base Business plan price is not repeated here, so the add-on row understates the total for a team starting from nothing. Google's pricing page says annual billing saves 16% on a one-year commitment, but it does not print an annual per-user price, so those cells stay empty. Microsoft prints both monthly and yearly figures, so only its side of the table is complete.

The gap at 25 seats is wide. Business Standard with Copilot costs $4,260 a year more than Business Standard with Gemini on monthly billing ($8,460 against $4,200). The two bundles are not the same suite, though, so the gap is not only the AI. Check which apps your team needs before you compare the totals.

Round by round

Cheapest with AI included: Google. Business Standard with Gemini beats the Copilot bundle on the same tier by $14.20 a seat a month, or $4,260 a year at 25 seats. Starter at $7.00 is cheaper still, but its Gemini covers the assistant in Gmail and chat, not the Docs and Sheets features. It is a cheaper product, not the same product at a lower price.

Yearly billing: Microsoft, on the numbers it publishes. Business Standard with Copilot drops to $23.50 a user a month on an annual plan, and the add-on drops too. Google does not print a yearly per-user price on the page we checked, so there is no like-for-like yearly comparison yet.

The Copilot add-on: the route to priority access. Microsoft's documentation separates two levels. Without the add-on, users get standard access to Copilot in Word, Excel, PowerPoint and OneNote, which Microsoft says is subject to service capacity and can vary through the day. The add-on gives priority access and grounds answers automatically in Microsoft Graph, which means mail, files, meetings, calendars and Teams. A team that wants Copilot to read its own files without manual uploads is paying for the add-on.

Company data: Copilot describes it more fully. Microsoft says the add-on grounds answers in the organization's mail, files and meetings without any upload. Google says Gemini in Drive helps find, summarize and synthesize information across your files, but its page does not describe how that grounding works in detail. Both use company data. Copilot's documentation is more specific, which makes it easier to check what a team actually gets before it signs.

Meetings: a tie. Teams summarizes and transcribes meetings and captures action items. Gemini in Meet takes notes. Pick the tool your meetings already run on, because switching meeting tools is a bigger cost than either AI feature.

Overall: Copilot for a Microsoft shop, Gemini for a Google shop. The price gap favors Google on monthly list prices. The app fit favors whichever suite your team already logs into. Pick the suite first, then the assistant that comes with it.

Which one to pay for

• You run Microsoft 365 with Outlook, Word and Excel as daily tools. Copilot is the right pick. Start with the base license's standard access, then buy the add-on for the people who live in Outlook and Teams. Expect $25.20 a month per add-on seat on top of the Business plan, or $21.00 on yearly billing. The $18.00 yearly rate is on sale only for purchases from July 1 to December 31, 2026, for existing Business customers, and it applies to the first year only.
• You run Google Workspace. Gemini comes with Business Standard and Business Plus, so there is no AI add-on to buy. Standard covers Gemini in Gmail, Docs and Meet, which matches most office work. A team that needs the expanded Gemini set has to pay for Business Plus at $22.00. Standard is the cheaper choice if its Gemini features cover the work.
• You work alone, with no suite. Google AI Pro costs $19.99 a month for an individual, according to Google's plans page. It gives higher Gemini usage than the free plan and 5 TB of storage. It is a personal plan, not a Workspace business plan. If free Gemini already does what you need, check the free plan limits first. For a free chatbot instead, see the best free AI chatbots. Our free Gemini Pro guide covers the ways to get the paid tier without paying for it.
• Your company mixes both suites. Pick by where the files live. Running both means paying for two seats per person, which costs more than either suite alone. If the question is which chatbot to use rather than which suite to buy, Claude vs Gemini covers the third option.

Where each one falls short

Copilot. Microsoft's pricing page says the add-on is for existing Microsoft 365 customers with an eligible Business plan, so a company has to hold that plan before it can add Copilot. Users without the add-on get standard access, which Microsoft says varies with capacity. Microsoft's documentation also uses several license names: Copilot Chat (Basic) and Microsoft 365 Copilot (Premium), which the pricing page calls Microsoft 365 Copilot Business. Check with your admin which one you are buying. If the question is the paid chatbot tiers rather than work suites, ChatGPT Plus vs Pro lays out the price steps.

Gemini. Starter's Gemini is basic: the Gmail assistant and chat, not the Docs or Sheets features. Gemini Enterprise is not priced on Google's Workspace pricing page, so this comparison leaves it out.

How we compared

We read Microsoft's Copilot business pricing page and its Microsoft Learn overview, updated October 1, 2026. We also read Google's Workspace pricing page, its Workspace AI page and its Google AI plans page. All of them were checked on October 10, 2026, and every price on this page comes from those pages. We also used Toolradar's live Microsoft 365 integration list, updated October 2026. We did not test either product or run it on real documents, so the feature notes describe what each vendor documents, not what the tools do in practice. The seat totals are our own arithmetic from list prices. Prices change often, so re-check both pricing pages before you buy.

FAQ

Bottom line

Pick the suite before you pick the assistant. A Microsoft team that works in Outlook and Excel gets the most from Copilot, and the add-on is what turns standard access into priority access. A Google team gets Gemini inside Business Standard at $14.00 a user a month billed monthly, the cheapest plan that covers Gemini in Gmail, Docs and Meet on these vendor prices. Check both pricing pages before you buy.
