Online document review
An AI contract review tool built for practical contract analysis.
Klause works as an online contract checker and contract analyzer for the document in front of you. It reads the supplied agreement and organizes the result into a plain-English summary, prioritized findings, obligations, key facts, missing protections, negotiation suggestions, and questions to ask.
The Review is document-grounded rather than a generic legal-risk score. Important findings include the supporting clause or passage so you can return to the source language and decide what needs clarification, negotiation, or professional advice.
Questions the review helps answer
Read the practical meaning—not only the legal wording.
- What am I agreeing to do?
- How can either party end the agreement?
- What happens when payment is late or disputed?
- Who owns the work, data, or intellectual property?
- Which clauses create the greatest exposure?
Common areas worth checking
One-sided termination rights
Unclear payment or renewal terms
Broad indemnity obligations
Missing or unlimited liability caps

Frequently asked questions
Before you start your review.
Can I review a contract online for free?
Yes. The Klause Free plan includes three complete Reviews with no credit card. Upload or paste the contract, then read the plain-English summary, prioritized findings, obligations, evidence, missing protections, and questions to ask.
What does the AI contract checker examine?
The Review looks for important payment, renewal, termination, liability, indemnity, confidentiality, intellectual-property, dispute, and governing-law language. Findings are tied to evidence from the document you provide.
Which agreements can the contract analyzer review?
Klause can review business contracts, consulting agreements, freelance contracts, purchase agreements, partnership agreements, vendor agreements, and other supplied contract text. The result is informational and not legal advice.
Does Klause provide legal advice?
No. Klause provides an informational document review to help you understand language, obligations, risks, missing protections, and questions worth raising. It is not a substitute for advice from a qualified lawyer.
What does the Review Report include?
The report includes a plain-English summary, prioritized findings, obligations, key facts, missing protections, negotiation suggestions, evidence from the document, and questions to ask before you proceed.
Can I review a PDF or DOCX file?
Yes. Klause supports common document formats including PDF, DOCX, TXT, Markdown, and CSV, subject to the current upload and document-length limits.
Review before you proceed
Start with the document in front of you.
Klause is an informational review tool, not a law firm and not a replacement for advice from a qualified legal professional.
