Compare Real Estate Contracts Instantly with AI
Upload two versions of a contract and get a clause-by-clause comparison with highlighted changes, risk flags on edits that increase your exposure, and a shareable plain-English summary — in under 60 seconds.
Why Contract Comparison Matters
Counter-offers, amendments, and redlines change the deal. A single edited clause can shift thousands of dollars in liability. Manually comparing versions is slow, error-prone, and easy to rush through when you're juggling multiple transactions.

What Fyxture Compares, Clause by Clause
Upload two versions — original and counter-offer, draft and amendment, or any two contract documents — and Fyxture identifies every change at the clause level.
Financial Terms
Price changes, earnest money adjustments, concession modifications, and any shift in who pays what.
Contingencies & Timelines
Inspection periods shortened or extended, financing deadlines moved, appraisal contingency changes.
Closing & Possession
Closing date changes, possession timing, per-diem penalties, and rent-back agreement modifications.
Liability & Obligations
Repair responsibilities shifted, warranty changes, insurance requirement modifications, indemnification edits.
Addenda & Riders
New addenda added, existing addenda modified or removed, rider conflicts with base contract language.
Boilerplate & Legal Language
Dispute resolution changes, governing law modifications, assignment rights, and notice provision edits.
Risk Flags on Every Change
Fyxture doesn't just show you what changed — it tells you why the change matters. Every edit is analyzed for risk impact so you know which changes to push back on.
Removed contingencies
A counter-offer that deletes the inspection contingency or shortens the financing window. Fyxture flags any contingency that was removed or weakened between versions.
Tighter refund or termination language
Edits that make it harder for the buyer to recover earnest money or exit the contract. Changes to default and remedy clauses that shift risk.
Shifted repair or liability obligations
Modifications that move repair responsibilities from seller to buyer, reduce warranty coverage, or limit seller disclosure obligations.
Deadline changes that create pressure
Inspection periods shortened from 10 to 5 days, closing dates moved up without corresponding timeline adjustments, notice periods reduced.
New or modified addenda conflicts
An amendment that contradicts terms in the base contract, or a new rider that introduces obligations not present in the original agreement.

Who Uses Contract Comparison
Buyer's Agents
Review counter-offers quickly and explain every change to your client in plain English. Know exactly what the seller changed and whether it increases your client's risk.

Transaction Coordinators
Verify that amendments match what was negotiated. Catch discrepancies between verbal agreements and written changes. Document every revision.
Investors & Acquisitions Teams
Compare deal terms across properties. Review lease amendments against originals. Track how terms evolve across a portfolio of transactions.
Frequently Asked Questions
What file formats does the comparison tool support?
Fyxture accepts PDF and DOCX files up to 20MB each. You can compare any combination — PDF vs. PDF, DOCX vs. DOCX, or PDF vs. DOCX.
Can I compare more than two versions?
Currently, Fyxture compares two documents at a time. For multi-round negotiations, compare each revision against the previous version to track how terms evolved.
Does it work with addenda and amendments?
Yes. You can compare a base contract against an amended version, or compare two different addenda. Fyxture maps clauses between documents even when formatting or structure changes.
Can I share the comparison with my client?
Yes. Every comparison generates a plain-English summary of what changed, what was added, and what was removed — designed to be shared with clients who don't want to read legal language.
How is this different from a Word redline?
Word redlines show text-level changes but don't tell you what they mean. Fyxture understands real estate contract language and flags which changes actually increase risk, shift liability, or affect deadlines.
