Review a contract from your side of the table
Generic AI reads a contract from nowhere — it has recommended clauses against its own user's interest. CruxDoc reviews as your side: your obligations, your risks, your deadlines, every finding quoted from the document and verified against the page before you see it.

How it works
Upload the contract
PDF, Word, or a scan — scans are read with OCR automatically.
Name your side
The tenant, the freelancer, the buyer. The review reads every clause from that seat.
Get ranked, cited findings
High to low severity, each with the exact clause quoted and checked against the page.
Verify in one click
Every verified quote links to its page in the reader; anything unverified says so.
The check happens before you see the answer
The failure everyone fears from AI on legal documents is the confident invention: a clause that is not there, a quote that says the opposite. CruxDoc's rule is mechanical, not aspirational — a quoted finding is string-matched against the document's text on the server, and a quote that fails is labeled unverified instead of shown as evidence.
The same engine answers follow-up questions in chat, extracts key terms as a table, and reads scanned agreements through OCR.
Beyond the review: five things it can hand you
Every tool reads the whole document, quotes it, and keeps the run in your history to reopen free or share as its own page.
Handoff report
The review as a lawyer-ready PDF: findings, key terms, every quote cited.
Deadline calendar
Every date with its page, downloadable as an .ics your calendar imports.
Compare versions
Two drafts, every changed clause quoted from each, ranked by what it costs you.
Playbook check
Your standard positions, checked clause by clause against this document.
Negotiation brief
What to push back on, what to concede, and the clause each point rests on.
Frequently asked questions
Q.01How does the AI contract review work?
Upload the contract, tell CruxDoc which party you are (the tenant, the contractor, the customer), and it reads every page from your side: obligations, liabilities, indemnities, termination traps, deadlines and unusual terms, ranked by how much they matter. Every finding quotes the clause it comes from.
Q.02Does it read the whole contract or just parts?
The whole document, every page. Reviews route through full-document reading, not keyword search — a review that reads 4% of a contract and misses a clause is a wrong review.
Q.03How do I know it is not making things up?
Every quote is string-matched against the actual document text on our servers before you see it. A quote that fails the check is shown as unverified instead of dressed up as evidence — you always know which findings to double-check.
Q.04Is this legal advice?
No. CruxDoc is a reading aid that shows you what the document says and where. For decisions that matter, take the cited findings to a professional — that handoff is exactly what the output is written for.
Q.05Is it free?
Your first document needs no account. A free account includes 100 questions a month; each review uses one.
