Claude now works inside Google Docs, Sheets and Slides

Claude just moved into the office suite that millions of people open every morning. On Tuesday, October 6, Anthropic released Claude for Google Workspace, an add-on that puts Claude in a sidebar inside Google Docs, Google Sheets and Google Slides. It is in public beta on all paid Claude plans, which means Pro, Max, Team and Enterprise. At the same time, Anthropic shipped new Google Docs, Sheets and Slides connectors, also in beta, that let Claude create and edit Google files straight from a normal Claude chat.

That sounds like a small product update, but it touches a very sensitive spot. Google Workspace is Google's home turf, and Google has spent the last two years building its own Gemini assistant into exactly these apps. The Verge described the new Claude sidebar as similar to Google's Gemini sidebar. So from today, people who pay for Claude can use a rival AI right inside Google's own documents, without copying text back and forth between browser tabs.

The three things you need to know

• What it is. Claude for Google Workspace is one add-on from the Google Workspace Marketplace. One install adds Claude to Docs, Sheets and Slides together. You open a file, go to Extensions, then Claude, then Open Claude, and a sidebar appears next to your work. Claude reads the file you have open, sees what you have selected, and edits the file in place.
• What it can do. In Sheets, Claude writes and fixes formulas, builds pivot tables and native Sheets charts, and adds new tabs. In Docs, it rewrites, restyles and restructures text, and it can propose changes as cards you accept or reject. In Slides, it builds new slides from the layouts and themes your deck already uses, and then checks for overlapping elements or text that is hard to read.
• You stay in control. The default mode is called "Ask before edits". Every change shows up as an approval card, and Claude waits for your click. You can switch to "Accept all edits" if you want Claude to work through a task without stopping. Some actions, like adding a link or removing someone's access, always need your approval in either mode.

How the add-on works in practice

The idea is simple: instead of bringing your file to Claude, Claude comes to your file. Anthropic's own example for Docs is a product requirements document. You ask Claude to tighten the executive summary and turn the next steps into a table, and it does both directly in the document. Small fixes, like a clumsy sentence or a heading in the wrong style, happen in place without touching the surrounding formatting. Bigger rewrites can arrive as suggestion cards in the sidebar. Each card highlights the passage it would change, so you can apply it or throw it away.

According to Anthropic's help center, every edit lands in the file under your own name. That matters more than it sounds. It means Claude's changes show up in the normal version history of the document, just like your own typing. If something goes wrong, you can press undo for the last change or restore an older version, the same way you would after a bad edit by a colleague.

Claude can also simply answer questions without changing anything. The help center lists prompts like "What does column F calculate?" or "Which slides mention pricing?" and says answers cite where in the file they came from. For many people that will be the most useful part: finally understanding a giant spreadsheet that someone else built years ago.

A closer look at Sheets

Spreadsheets are where this add-on could save the most time. Anthropic says Claude can write formulas, build pivot tables and native Sheets charts, and add new tabs. For harder jobs like joins or data cleaning, it can pull a range into Python and write the results back into the sheet. The example in the announcement is a Q3 budget versus actuals report: you start from an empty sheet, attach your source files, and ask for one tab per team plus a summary chart, and Claude can flag anything that is over budget.

The help center gives more everyday examples. You can ask Claude to explain how a total is calculated and flag hardcoded numbers, to normalize a column of dates written in three different formats, or to find out why a lookup formula returns errors for some rows and fix it. Those are exactly the tasks that eat half an afternoon in a normal office week.

Docs and Slides

In Docs, the add-on is built for drafting, rewriting and restructuring long documents. Anthropic's help center suggests requests like cutting a 14 page brief to 6 pages without losing any numbered requirements, or checking a contract for defined terms that are used but never defined. Claude can work on every tab of a document, but it cannot create, rename or reorder the tabs themselves, and it cannot read or resolve comments yet.

In Slides, Claude builds new slides that match the layouts and theme of the deck you already have. After that, it checks its own work and flags elements that overlap, run off the slide, or are hard to read. One limitation is worth knowing: charts that Claude creates in Slides are inserted as images, not as linked Sheets charts, so they do not update when the numbers change.

The new connectors: starting from the chat

The add-on is only half of the launch. The other half are the new Google Docs, Sheets and Slides connectors, which work from the other direction. You stay inside Claude, paste a link to a Google file or ask for a new doc, sheet or deck, and on supported setups the file opens in a pane next to your conversation. Anthropic says this makes the most sense when you need a brand new file or when your work spans several files. Claude's access through the connectors matches your existing Google sharing permissions, so it can only reach files you can already reach.

On Team and Enterprise plans, an owner or primary owner has to switch the connectors on first. For the add-on itself, Google Workspace admins can install it for the whole domain or only for selected groups from the Google Admin console.

What Claude can and cannot see

Privacy is the first question most people will ask, and the help center answers it in detail. The add-on asks Google for two permissions: one to show a sidebar, and one to view and manage the documents, spreadsheets or presentations it has been installed in. According to Anthropic, Google enforces that the extension can only work on the one file it was opened in. It does not request access to Drive, Gmail, Calendar or contacts.

Anthropic says it does not use this content to train its models, and that inputs and outputs are deleted from its systems within 30 days, with some exceptions described in its data retention policy. Your chat history with Claude is stored locally in your browser, per file, and does not sync across devices. Collaborators see the edits Claude made, attributed to you, but they do not see your conversation.

Anthropic also addresses prompt injection, which is a real risk for any AI that reads documents from other people. Files can contain hidden instructions, for example in white text or tiny fonts. The help center says Claude treats document content as data rather than commands, labels hidden text it finds, and is designed not to follow instructions inside a document to share the file, fetch a link or contact anyone. Claude also cannot share a file, give anyone access or change the owner, even if you ask. Still, Anthropic itself recommends reviewing Claude's proposed actions before approving them, especially in files that come from outside your organization.

The limits of the beta

This is a beta, and the help center is refreshingly open about what does not work yet:

• It works only on the file it was opened in. It cannot open, create or copy other Drive files, and it cannot export a PDF.
• You need to keep the sidebar open while Claude works. Closing it stops the task.
• Chrome, Edge and Safari are supported. Firefox is not supported in this beta.
• Google stops a single long operation after six minutes, so very large jobs should be split into stages.
• Voice dictation is not available in the sidebar.
• On Enterprise plans, the Compliance API, customer managed encryption keys and OpenTelemetry audit export apply, but zero data retention is not available, and the help center says the add-on should not be used with protected health information.

Why it matters

The fight over AI assistants is moving away from the chat window and into the tools where work actually happens. Microsoft has Copilot in Office, Google has Gemini in Workspace, and Anthropic already offers Claude for Microsoft 365. With this launch, Claude now sits inside both of the big office suites. For companies that like Claude's writing and analysis but run their business on Google Docs and Sheets, the main reason to stay with Google's own assistant just got weaker.

It also changes the daily routine for a lot of people. Until now, using Claude on a spreadsheet meant exporting it, uploading it, asking a question, and then copying the answer back by hand. That friction is gone. When the AI can see your selection and make the change itself, with your approval, it stops being a separate tool and becomes part of the document.

And it shows where Anthropic wants to grow. The company is heading toward its IPO, and office work for teams is where the steady subscription money is. Making Claude useful in the files people already have open is a direct way to win those seats.

Dany's take

I like how careful this launch looks. "Ask before edits" as the default is the right call, and so is the hard rule that Claude can never share a file or change who has access. The biggest risk with AI inside documents is not a bad formula, it is an assistant quietly doing something you did not want, so I am glad Anthropic put the brakes in by default. The part I find most interesting is Sheets. Explaining an old spreadsheet, fixing broken formulas and building a clean report from messy data is boring work that almost everybody does, and it is exactly where a good model shines. My advice: if you already pay for Claude, install it, open one of your real spreadsheets and ask it to explain the biggest formula in there. Just keep the default mode on until you trust it, and be careful with files from strangers. I will be watching how Google answers, because having a competitor sitting right inside Docs is not something they will ignore for long.
