Welcome
LegalSifter ReviewPro is a Google Docs sidebar that uses AI to review your contracts. You select a playbook, ReviewPro analyzes your document, and you get structured insights with proposed changes. You can then generate a redlined copy of your document with those changes shown as Google Docs suggestions.
This guide covers everything you need to know as a contract reviewer.
Quick Start
Get from an open contract to a redlined document in seven steps.
Open the Sidebar. In your Google Doc, go to Extensions › LegalSifter ReviewPro › Open LegalSifter ReviewPro. The sidebar appears on the right side of your document.
Sign In. Click Sign In. A login window opens — enter your LegalSifter credentials and complete authentication. The window closes automatically and the sidebar loads your account.
If the login window doesn't appear, your browser may be blocking popups. Allow popups for
docs.google.comand try again.Authorize Document. ReviewPro needs one-time access to this document to run a redline. We only request access to this file — not your entire Drive.
Choose a Playbook. The Playbooks tab shows your available playbooks. Use the search bar to filter by name if needed. Find the playbook you want and click Redline.
Document Analysis. ReviewPro analyzes your document. You'll see progress stages as the analysis runs (typically 30–60 seconds). When complete, the sidebar automatically switches to the Redlines tab.
Create Your Redlined Document. After the document analysis finishes, click Create Redlined Document. ReviewPro generates a new copy of your document with all proposed changes shown as Google Docs suggestions.
Review the Results. The sidebar automatically opens the Redlines tab showing results organized into a Summary, provisions with proposed changes, and a Compliant section.
Getting Started
Opening the Sidebar
The LegalSifter ReviewPro sidebar is available from the Google Docs menu:
Extensions › LegalSifter ReviewPro › Open LegalSifter ReviewPro
The sidebar opens on the right side of your document. If you've used ReviewPro before on this document, it may restore your previous review session automatically — including any sift that was still running when you last closed the sidebar.
Signing In
When the sidebar opens, you'll see a sign-in prompt with the value proposition:
"Choose a playbook. Redline your contract against your company's positions — in minutes."
Click Sign In. A login window opens — enter your email and password.
After successful authentication, the window closes and the sidebar loads.
If you don't have an account yet, click Request a Demo to visit the LegalSifter sign-up page in a new tab.
📝 Note: You'll need to sign in each time you open the sidebar. This is a security measure to protect your account.
Authorize Document
After signing in, the Authorize Document message will be shown. ReviewPro needs one-time access to this document to run a redline. We only request access to this file — not your entire Drive.
Click the Authorize Document button. A new window appears — select the current document and click Select.
Sidebar Layout
Once authorization is done, the sidebar has up to three tabs at the bottom:
Tab | Purpose |
Redlines | View analysis results and insights for your document |
Playbooks | Browse and select playbooks to start a review |
Profile | View your account info, credits, settings, and sign out |
The active tab is highlighted with an orange indicator.
📝 Note: The Playbooks tab is hidden automatically after a sift completes so you can focus on results. It reappears only when you choose to re-analyze the document with a different playbook (see "Re-analyzing with a Different Playbook").
Selecting a Playbook
The Playbooks tab is where you choose which playbook to use for reviewing your document.
Browsing Playbooks
Each playbook card shows:
Name — the playbook title
Description — a summary of what the playbook covers
Redline button — click to start the review
Updated date — when the playbook was last edited
Some playbooks may show an Inactive badge, indicating they are not currently available for use.
Searching
Use the Search playbooks… bar at the top to filter playbooks by name. The list updates as you type.
Starting a Review
Once you've found the right playbook, click the Redline button on its card. This begins the analysis of your document.
⚠️ Heads up: If you see the banner "You do not have permission to redline documents. Contact an administrator for access," your account has read-only or view-only access. Contact your administrator to request the required permissions.
Creating a Redlined Document
Generating the Redlined Document
Click Create Redlined Document. The button shows "Creating…" while the document is being prepared.
When ready, the new document opens automatically in a new browser tab.
The sidebar shows an Open Redlined Document link so you can return to it later.
What to Expect in the Redlined Document
The new document is a copy of your original with ReviewPro's accepted changes shown as Google Docs suggestions:
Proposed deletions appear as suggestion strikethroughs
Proposed insertions appear as suggestion additions
Comments you added in the sidebar appear as Google Docs comments
You can accept or reject each suggestion individually using Google Docs' built-in suggestion tools, just like any other Google Docs suggestion.
Navigating the Redlined Document
When you open the redlined document, you can reactivate the ReviewPro sidebar, which will automatically load the analysis results for that document. You can click action cards to navigate to specific clauses, just like in the original document.
Re-analyzing with a Different Playbook
After a sift completes, you'll see a secondary link labeled Redline again with a different playbook below the results. Clicking it:
Clears the current results
Re-shows the Playbooks tab
Lets you pick a different playbook and run a fresh analysis against the same document
💡 Tip: This is handy if you maintain different playbooks for different contract types or jurisdictions.
Resuming an In-Progress Analysis
If you close the sidebar (or Google Docs crashes) while a review is still running, don't worry — the next time you open the sidebar on that document, it automatically detects that a review is in progress and resumes showing the progress view. You don't need to start over.
Reviewing Your Document
Once the analysis completes, the sidebar automatically switches to the Redlines tab. The results are organized into three main areas:
Summary — at-a-glance statistics about what was found
Provisions with changes or alerts — the findings that need your attention
Compliant — provisions that already meet the playbook's positions
Summary
At the top of the Redlines tab, the Summary card shows at-a-glance statistics for the current analysis.
What's in the Summary
Total provisions reviewed — how many provisions the playbook checked against your document
Compliant provisions — count and percentage of provisions that passed
Changes or alerts — count and percentage of provisions needing attention
Total changes / alerts — total number of individual proposed changes and alerts across the whole document
Breakdown by Change Type (shown when there are changes)
Change Type | What It Means |
Added Terms | Language ReviewPro proposes to insert |
Modified Terms | Language ReviewPro proposes to rewrite |
Deleted Terms | Language ReviewPro proposes to remove |
Added Comments | Comments ReviewPro proposes to add for discussion |
Triggered Alerts | Flags where a provision is missing or unusually risky |
Interacting with the Summary
Click the Summary header to collapse or expand it
Use the Summary to decide where to start — for example, if there are many Alerts, prioritize those
Check Feature (Mark Provision as Checked)
As you work through the findings, you can mark provisions as Checked to signal you've reviewed them and move them out of your active list.
How to Check a Provision
Expand a provision card
Click Mark as Checked
The provision disappears from the open list and moves into the CHECKED section at the bottom
What Changes Visually
The checked provision gets a green Checked badge
The CHECKED section header shows a count of how many provisions you've checked
The section is collapsible — click the header to show or hide its contents
💡 Tip: Your checked state is saved, so if you close and reopen the sidebar for the same document, your checked provisions remain checked.
Uncheck (Reopen a Checked Provision)
If you marked a provision as checked by mistake — or need to revisit it — you can reopen it at any time.
How to Uncheck a Provision
Expand the CHECKED section at the bottom of the Redlines tab
Find the provision you want to reopen
Click Uncheck (shown with an undo icon next to the provision)
The provision is immediately restored to the open list in its original position, along with all its action cards.
Focus in Document
When you're reviewing an action card, you can jump directly to the matching location in your Google Doc.
How It Works
Expand an action card in the Redlines tab
Click Focus in document
The button briefly shows "Focusing…" while ReviewPro locates the passage
Your cursor moves to the relevant location in the document and the passage is highlighted briefly in yellow so you can spot it
📝 Note: If an action applies to multiple places in the document, the card shows "{n} locations" — clicking Focus in document walks through them.
💡 Tip: Use this to read the original language in context before deciding whether to accept or modify the suggestion.
Action Card Details (Once Expanded)
Click any action card to expand it. Each expanded card shows everything you need to evaluate the proposed change in one place.
What's on an Expanded Card
Action name — a short description of the finding (e.g., "Add mutual non-disclosure clause")
Location count — shows "{n} location" or "{n} locations" if the action matches more than one passage
Focus in document button — jumps your cursor to the matching text in the Doc
Suggested Changes — the heart of the card:
Remove: text shown in strikethrough that ReviewPro suggests deleting
Add: text shown in green that ReviewPro suggests inserting
Modified: if you've edited the proposed text, your edited version appears here
Proposed: the original proposed language (shown alongside Modified after you edit it)
Compliant Section
The Compliant section lists all provisions in your contract that already align with the playbook — no changes needed.
What You See
A collapsible section titled Compliant with a green pill badge showing the count (e.g., "5 Pass")
Click the section header to expand or collapse the list
Each compliant provision appears as a card with the provision name and a Pass badge
💡 Tip: The Compliant section confirms what's already working in the contract so you don't have to go looking for it. Reviewing this list is a quick way to validate that the contract covers your baseline positions.
Your Profile & Settings
The Profile tab shows your account information and add-on settings.
Account Information
Name and Email — your LegalSifter account details
Credit Balances — your available Sift Credits and Document Credits
Settings
Setting | Options | Description |
Theme | Light, System, Dark | Controls the sidebar's appearance. System follows your device's theme setting. |

Getting Help & Troubleshooting
Support Chat
LegalSifter ReviewPro includes built-in support chat powered by Intercom. Look for the chat option in the sidebar to start a conversation with the support team.
Common Issues
Login window doesn't appear
Your browser is likely blocking popups. Allow popups for docs.google.com in your browser settings, then try signing in again.
Session expired
If your session expires while you're working, the sidebar shows a "Your session has expired" message with a Sign In Again button. Click it to re-authenticate — your review progress is preserved, so you won't lose your place.
Analysis takes too long or fails
If the analysis exceeds the expected time, you'll see an error with a Retry button. Click it to try again. If the problem persists, check your internet connection or contact support.
"No connection" error
This appears when the sidebar can't reach the server. Check your internet connection and click Retry. The message reads: "Unable to reach the server. Check your internet connection and try again."
"Something went wrong" error
If the sidebar encounters an unexpected error, you'll see a Try Again button. Click it to reload. If the issue persists, try closing and reopening the sidebar from the Extensions menu.
Redlined document doesn't open
If the new tab doesn't open after clicking Create Redlined Document, your browser may be blocking the popup. Allow popups for docs.google.com and click the Open Redlined Document link that appears in the sidebar.
My permissions look wrong (can't redline even though I should be able to)
Sign out and sign back in — this refreshes the permission cache. If the issue persists, contact your administrator to verify your account's scopes.
❓ Need more help? Reach the LegalSifter team right from the sidebar via the built-in Intercom chat — or ask your administrator for account-level questions like permissions, credits, and playbook management.
