Claude now works inside Google Docs, Sheets and Slides, the same files where Google’s own Gemini already lives. For Europe’s small firms the news is not which assistant is smarter. It is that the assistant has stopped asking you to come to it.
FROM THE EDITORS
Every office has a desk by the window that nobody owns. On 6 October Anthropic moved into the one in Google’s office. Claude for Google Workspace is now in public beta on all paid Claude plans: an add-on from the Google Workspace Marketplace that opens in a sidebar next to the document, the spreadsheet or the deck you already have open. Extensions, Claude, Open Claude. No new tab, no copy and paste, no export.
That sounds like a convenience. It is a change of address. Until now, using Claude on your work meant taking the work to Claude. From today, Claude comes to the work, in a building whose landlord sells a competing tenant.
What it actually does
In Docs, Claude fixes a sentence or restyles a heading in place, and proposes larger rewrites as suggestion cards you accept or reject. In Sheets it writes formulas, builds pivot tables and native charts, adds tabs and, in Anthropic’s own example, flags anything that is over budget; for joins and data cleaning it can pull a range into Python and write the result back into the sheet. In Slides it builds new slides from your deck’s own layouts and theme, and flags elements that overlap, run off the slide or are hard to read.
The default mode is “Ask before edits”: every change arrives as an approval card with a summary, and nothing happens until you click. “Accept all edits” lets Claude work through the job on its own. Claude’s access matches your existing Google sharing permissions, and admins can deploy it to the whole domain or to selected groups from the Google Admin console. Enterprise customers keep the Compliance API, customer-managed encryption keys and audit export they already had. A separate set of connectors, also in beta, lets you paste a Google file link into a Claude conversation and have it create or edit the file from there.
Why move in next to Gemini
The obvious objection: Google already puts Gemini in these apps, and bundles it into its business Workspace plans. Why would a small firm pay a second time for an assistant in the same sidebar?
Because the desk is not the point. The chair is. A firm that has built its quoting, its customer replies or its monthly reporting around Claude’s way of working no longer has to choose between that and the files its staff live in. And Anthropic’s models already sit inside Microsoft 365 through Copilot. With this launch, Claude has a desk in both of the offices where Europe’s small businesses do their paperwork. It is becoming the one colleague who works in either building.
For Google this is calculated hospitality. Workspace gets stickier when the best-known rival model works inside it rather than pulling users out of it. For Anthropic it is distribution without a sales force. For the customer it is the rarest thing in software: a choice made at the level of the sidebar, not the suite.
The adoption problem it quietly solves
Eurostat’s latest survey found 20 per cent of EU enterprises with ten or more staff using any AI technology, and only 17 per cent of small ones. The common explanation is skills. The less flattering one is friction. An assistant that lives in another tab is a tool for the one person in the firm who likes tools. An assistant that lives in the budget sheet is a tool for whoever opens the budget sheet.
That is the shift worth watching. The bookkeeper in Aarhus does not need to learn prompting to ask the sheet which suppliers went over budget in September. The office manager in Lyon does not need a new app to turn three pages of minutes into a summary at the top of the same document. The work stays where it was. The help moves in.
Read the lease before you unpack
A beta is a beta, and three things deserve attention before a small firm switches it on for everyone.
First, permissions. Claude sees what you can see. If your shared drive is a decade of “anyone with the link can edit”, that is now the assistant’s reach too. Tidy the sharing before you install the add-on, not after.
Second, the plan. The add-on needs a paid Claude plan: Pro is $20 a month, or $17 billed annually; Team starts at $25 a seat a month, or $20 annually. For anything involving customer or employee data, a commercial plan is the defensible choice, because it is where the data-training protections and the admin controls come standard. Check the data processing terms before the first invoice goes in, not after.
Third, the mode. “Accept all edits” is a fine way to restyle forty slides. It is a poor way to touch the sheet your VAT return is built on. Keep “Ask before edits” as the default for anything with money or names in it, and let the cards be the audit trail.
What to do this week
- Install it for one person, on one workflow. The monthly budget sheet or the standard quote template. Measure whether it saves an hour before rolling it out.
- Fix the sharing first. Remove old “anyone with the link” files from the drive the pilot can reach.
- Pick the plan on purpose. Pro for trying it; Team once it touches customer data or more than one colleague.
- Keep approvals on. Every accepted card is a record of what changed and who said yes.
- Do not cancel Gemini to make a point. Run both on the same task for a month. The assistant that wins is the one your staff actually open.
For two years the AI question for small firms has been which model to choose. That question is getting less interesting by the week. The better question is where the help sits, and as of today, for anyone who works in Google’s apps, it sits at the desk by the window, next to the file, waiting for you to click yes.
