Google Docs with Markup AI Chrome Extension

Check, score, and fix your content without leaving Google Docs. The Markup AI Chrome extension adds a side panel to Google Docs that reviews the document you’re writing in, highlights the issues it finds, and writes the fixes you accept straight into the document, or adds them as suggestions or comments for someone else to decide.

Checks run against the brand standards your organization has configured in the Markup AI console — the same standards enforced everywhere else you write. See the agent documentation for what each agent looks for.

What you need

• A Google account with access to Google Docs.
• A Chromium-based browser — Chrome, Edge, Arc, Dia, Brave, or another browser built on Chromium. Safari and Firefox aren’t supported.
• A Markup AI account. Don’t have one yet? Create your organization at the Markup AI console.
• Permission to install browser extensions. If your browser is managed by your organization, an admin may need to deploy it first.

Installing the extension

There are two ways to get the extension: install it yourself from the Chrome Web Store, or have an admin deploy it across your organization.

Option 1: Install it yourself

Option 2: Deploy to your organization (admins)

If your users’ browsers are managed, you can force-install the extension so nobody has to install it themselves. Pick the tool you manage browsers with:

Use it in a document

1. Open any document in Google Docs.
2. Open the side panel by selecting the Markup AI icon (from the toolbar or your pinned extensions) or the floating Markup AI button in the document.
3. Select Log In and sign in with your account credentials, through Google or Microsoft authentication, or your organization’s single sign-on. Your sign‑in persists for future sessions.

Two ways to review

The panel comes in one of two versions, depending on whether your organization uses the Style Agent. Both check against the same brand standards and both work the same way with Google Docs edits, suggestions, and comments. They differ in how you start a review and how the results are organized.

• Organizations without the Style Agent — The panel offers Start Review. Select it and the extension reviews the whole document in one pass. Findings come back as a single prioritized list rather than a list per agent, so you work through what matters most first. Use View as to switch between Focus Areas, Priority Groups, and Document Order, and filter by priority level to narrow the list.
• Organizations with the Style Agent — The panel lists your organization’s agents. Choose the ones you want to run, then select Check. Results are grouped by agent, each with its own score, and the panel shows the document’s overall Content Risk level. Issues that have no one-click fix offer Mark as Resolved so you can clear them once you’ve handled them yourself.

Review and act on issues

Each issue shows the flagged text, why it was flagged, and the suggested fix when there is one — and the text is highlighted in your document. Select an issue to jump straight to the matching text.

For each issue you can:

• Apply the fix — replace the flagged text with the suggested rewrite. The fix is written into the document the same way a change you type would be, so Ctrl+Z (⌘Z) undoes it like any other edit.
• Add it as a suggestion — insert the fix as a Google Docs suggestion (tracked change) for someone to accept or reject.
• Add it as a comment — add a Google Docs comment with the finding, anchored to the flagged text.
• Dismiss it — set an issue aside without changing your document.

Results are saved per document, so you can close and reopen the panel without losing your place.

FAQ

• Can I choose which agents run? If your organization uses the Style Agent, yes: pick them from the list before you select Check. Otherwise the review uses the standards your organization has configured in the Markup AI console, and there’s nothing to pick.
• Do I need to update the extension? No. When a new version is released, your browser updates the extension automatically — you’ll always be on the latest version.
• The panel shows “Unable to connect to page” — what should I do? Reload the document and the extension will reconnect.

Known limitations

• Runs in Chromium browsers — not Safari or Firefox. Per-browser details are in Browser notes.
• Checks cover text content; images, charts, and other non-text elements aren’t analyzed.

Browser notes

The install steps above work the same in every Chromium browser: one Chrome Web Store listing, one side panel, one set of features. What differs is the wording of the install button, where the Extensions menu lives, and a setting or two. Pick your browser:
