What Is a Commercial Lease? Key Terms, Types, and What to Watch For
A commercial lease is a legally binding contract between a landlord and a business tenant. Learn the key terms, lease types, and critical clauses before you sign.
A free AI lease abstraction tool that uploads a lease PDF and returns a summarized extraction of key terms. Marketed to real estate professionals as a quick, no-cost way to review a lease.
Lextract wins 6 of 8 feature categories
Based on features, pricing, and workflow integration
Kolena offers a free AI lease abstraction tool that summarizes key lease terms from an uploaded PDF. It targets real estate professionals who want a quick overview without paying for a dedicated platform. The tool has gained traction among brokers and analysts who need a fast sanity-check on a lease document before committing to a deeper review.
The difference becomes clear when you need structured, exportable data. Kolena returns a readable summary -- useful for a first glance, not useful for loading into Yardi, verifying rent roll data, or running due diligence across a portfolio. Lextract returns 126 structured fields with per-field confidence scores, 20 automated red flag checks, and export formats (JSON, Excel, Word) ready for property management systems and financial models.

$15 for a single lease. Volume pricing: $65 for 5 leases ($18 each) and $120 for 10 leases ($17 each). No subscription, no implementation fees.
Free. No published paid tier or enterprise pricing as of early 2026.
Kolena is free, which makes it hard to compete on price for one-off, casual use. If you need a free tool to quickly review a lease clause or get a rough summary before a meeting, Kolena works. The cost comparison changes entirely when you need structured, exportable data: a free tool that returns unstructured text has zero value for loading data into a property management system, building a financial model, or running due diligence on 50 leases. The $15 per lease Lextract charges is the cost of getting data you can actually use.
Property managers, tenant representatives, CRE investors, and corporate real estate teams who need accurate structured lease data for due diligence, PMS import, portfolio review, or ASC 842 compliance.
Individual brokers, analysts, or tenants who need a free, quick summary of a lease document without requiring structured output or portfolio-scale workflows.
Lextract is the stronger choice for any CRE professional who needs data they can actually use. Kolena may make sense for the casual user who only needs a free, quick read of a lease with no downstream data requirements -- but for the majority of property managers, brokers, and analysts who need to load fields into Yardi, build a rent roll, or run due diligence, a text summary is the wrong output format regardless of price.
Lextract returns 126 structured fields, confidence scores, and 20 red flag checks exported in formats that plug directly into the systems CRE professionals already use. For any workflow where the data needs to be actionable, Lextract is the right tool.
