Anthropic has put Claude directly inside Google Docs, Sheets, and Slides. Announced on October 6, 2026, the new add-on opens a Claude sidebar next to whatever file you already have open, so you can ask it to rewrite a paragraph, fix a spreadsheet formula, or clean up a slide deck without copying anything into a separate chat window first. It’s in public beta for everyone on a paid Claude plan.
TL;DR
Claude for Google Workspace is a free add-on (included with any paid Claude plan, from $17/month) that puts a Claude sidebar inside Google Docs, Sheets, and Slides. It reads and edits the one file you have open, shows every change as an approval card by default, and can’t touch your wider Drive, Gmail, or Calendar unless you’ve separately connected those. It’s genuinely useful for everyday document and spreadsheet work, but it has real beta limits worth knowing before you rely on it.
What it actually does
Install it once from the Google Workspace Marketplace and it works in all three apps — you don’t install separate extensions for Docs, Sheets, and Slides. Open any file, go to Extensions, Claude, Open Claude, and a sidebar appears next to your document. From there Claude can read the file, see what you’ve selected, and make edits in place.
According to Anthropic’s own announcement and help center documentation, what you can ask it to do differs a bit by app:
| App | What Claude can do | How changes land |
|---|---|---|
| Google Docs | Rewrite, restructure, and restyle text; turn notes into tables; tighten long sections without breaking formatting | Direct edits, or as suggestion cards you accept/reject one at a time |
| Google Sheets | Write and debug formulas, build pivot tables and native charts, add tabs, clean up inconsistent data, pull a range into Python for joins | Direct edits, shown as approval cards in the default mode |
| Google Slides | Build new slides matching the deck’s existing layout and theme; flag text that’s cut off or overlapping elements | New slides or edits you review before accepting |
You control how much Claude does before checking in. The default mode is “Ask before edits” — Claude describes what it’s about to do in plain language and waits for you to click Allow. Switch to “Accept all edits” and it works through a task without stopping for routine content changes, though per Anthropic’s help documentation it still always pauses for anything that touches links, external images, or someone’s access to the file — there’s no way to turn that particular check off.
It’s not a separate subscription. Claude for Google Workspace is included with any paid Claude plan — Pro, Max, Team, or Enterprise — at no extra charge. Pro starts at $17/month billed annually (or $20/month billed monthly), per Claude’s pricing page. There’s no free-plan version.
What it can’t see or do
The permission model here is intentionally narrow. Claude only requests two Google permissions: one to show the sidebar, and one to read/edit the specific file it was opened in. Per Anthropic’s help center, it does not request access to your Drive, Gmail, Calendar, or contacts, and it cannot open, create, or copy any other file — it only sees the one you have open, plus anything from connectors you’ve separately turned on (like a Google Drive or Salesforce connector already configured in your Claude account).
There’s a real list of things it won’t do even if you ask, documented directly by Anthropic:
- It cannot share a file, change who owns it, or grant anyone access — those actions are refused outright.
- In Google Docs, it can’t read, reply to, or resolve existing comments (paste a comment into the chat if you want Claude to act on it), and it can’t create or reorder document tabs.
- In Google Sheets, it can’t read “Connected Sheets” tabs that pull live BigQuery data, and it can’t set up triggers or scheduled refreshes.
- In Google Slides, charts it builds are inserted as static images, not linked Sheets charts — they won’t update automatically if your underlying numbers change.
- A single operation is capped at six minutes by Google before it’s cut off, so very large jobs need to be broken into stages.
- Firefox isn’t supported in this beta; Chrome, Edge, or Safari are required.
Files can contain hidden instructions. Anthropic’s documentation notes that a document could contain text written by someone else — sometimes hidden in white-on-white formatting or a tiny font — that tries to instruct Claude to do something the actual user didn’t ask for, like sharing the file or fetching a link. Claude is designed to treat document content as data rather than commands and to flag hidden text it detects, but Anthropic itself still recommends reviewing proposed actions carefully, especially in files that came from outside your organization.
How this compares to just using Gemini
The obvious question is why you’d add a third-party AI to Google’s own apps when Google’s Gemini is already built into Workspace for free. The honest answer is that it depends on which AI you already use for everything else.
Claude for Google Workspace
Requires a paid Claude plan on top of whatever Google Workspace plan you have. Brings your existing Claude connectors, skills, and (on Enterprise) Compliance API/audit logging into the sidebar. Makes sense if your team already standardizes on Claude for other work and wants that consistency inside Google files.
Google’s own Gemini in Workspace
Already included with most Google Workspace business/enterprise plans at no separate per-seat AI charge, and integrates natively with Gmail, Calendar, and Drive search without a separate connector setup. Makes sense if you don’t already have an established Claude workflow elsewhere.
Neither replaces the other’s wider product — this add-on is scoped to one open file at a time, not a general assistant across your whole Drive.
What’s not confirmed yet
Anthropic has not published a fixed date for when this leaves beta, or whether a cheaper or free tier will eventually get access — right now it requires a paid plan, full stop. It’s also worth noting this follows the same pattern as Claude for Microsoft 365, which Anthropic had already shipped earlier; the Google Workspace version is explicitly the second major office-suite integration, not the first.
Do I need to install Claude separately in Docs, Sheets, and Slides?
No. One install from the Google Workspace Marketplace adds it to all three apps at once.
Can Claude see my other files in Google Drive, or my email?
Not by default. It’s restricted to the single file it was opened in, plus anything from connectors (like a Drive connector) you’ve separately enabled in your Claude account. It does not request Gmail or Calendar access through this extension.
Can my collaborators see my chat with Claude?
No. The conversation is stored locally in your browser, per file. Collaborators see Claude’s resulting edits in the document and in Version History, attributed to you, but not the chat itself.
Does this use my documents to train Claude’s models?
Anthropic’s help documentation states it does not use this content for model training, and that inputs and outputs are deleted from Anthropic’s systems within 30 days, with some exceptions detailed in its data retention policy.
Is there a free version?
No. It’s available on paid Claude plans only — Pro ($17-20/month), Max, Team, or Enterprise. There’s no access on Claude’s free tier.
What if my company blocks Marketplace app installs?
That’s a Google Workspace admin setting, not a Claude one. A Workspace super admin can either allowlist Claude so individuals can install it themselves, or install it for the whole domain (or specific groups) directly — both options are available even when general Marketplace installs are blocked.
