What your
report looks like
Every flag comes with a severity rating, a plain-English explanation of the risk, and a concrete suggested fix you can use in negotiation.
Critical flags
Clauses that could cause significant financial loss, IP forfeiture, or legal liability
Warning flags
Unfair clauses worth negotiating — they won't kill you but they should change
Minor flags
Slightly one-sided terms — worth noting, low urgency
📄 Freelancer / Client Agreement
🔴 High Risk
Score: 78/100
Scanned against 60+ rules. Found 8 flags (3 critical, 4 warning, 1 minor) and 3 missing clauses.
Critical
Intellectual Property
All Inventions Assigned to Client
Everything you create — including side projects — becomes the client's property.
Fix: "Assignment excludes inventions on Contractor's own time unrelated to Client's business."
Warning
Payment Terms
Net-90 Payment Terms
You must wait 90 days after invoicing to receive payment — severe cash flow risk.
Fix: Negotiate to Net-30. Add 1.5% monthly interest on overdue invoices.
Critical
Scope
Unlimited Revisions Required
No limit on changes — a fixed-price project could require unlimited unpaid rework.

Got Questions?
Frequently Asked
Is ClauseGuard actually free? What's the catch?
Completely free, no catch. ClauseGuard runs locally in your browser using a built-in rule dictionary — there's no AI backend, no server costs, and nothing to pay for. The source code is open. If you find it useful, a Ko-fi or GitHub star is appreciated but entirely optional.
Does my contract text get sent anywhere?
Never. All scanning runs entirely within your Chrome browser using local JavaScript. No network requests are made during analysis. Your contract text is stored temporarily in Chrome's local storage between the popup and the results tab, then deleted immediately. See our Privacy Policy for full details.
What types of contracts does it work on?
ClauseGuard works on employment contracts, freelancer/client agreements, B2B commercial agreements, NDAs, and service agreements. It detects contract type automatically and scores risk accordingly. It works on web pages, PDFs opened in Chrome, Word documents (.docx), Google Docs, and signing platforms like DocuSign, PandaDoc, and HelloSign.
Can it read PDFs and Word documents?
Yes. For PDFs opened in Chrome, ClauseGuard fetches the raw file and extracts text from the PDF content streams. For Word documents (.docx), it reads the ZIP-based file format to extract text from document.xml. Note: scanned/image-based PDFs cannot be read — if a PDF is image-only, open it in Google Docs first (which has built-in OCR) and scan from there.
Is this legal advice?
No. ClauseGuard is an informational tool that flags potentially problematic contract language based on common patterns. It does not constitute legal advice. For high-value or complex contracts, always consult a qualified attorney in your jurisdiction. The tool is designed to help you ask better questions and know what to negotiate — not to replace professional legal counsel.
How do I report a false positive or suggest a new rule?
Open an issue on GitHub. Include the clause text that triggered the false positive and the contract context. For new rules, describe the clause pattern, its risk category, and why it's harmful. Community contributions are welcome and reviewed promptly.
Does it work on all websites?
It works on any standard web page and most contract platforms. There are two exceptions: Chrome's own system pages (chrome://) cannot be accessed by any extension, and some heavily sandboxed enterprise platforms may block content scripts. In those cases, try selecting and copying the contract text manually, pasting it into a plain text file or Google Doc, and scanning from there.
