Lextract vs Kolena
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.
Overview
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.
Feature Comparison
| Feature | Lextract | Kolena | Advantage |
|---|---|---|---|
| Extraction Output | 126 structured fields with per-field confidence scores | Human-readable text summary of key lease terms | Lextract |
| Price per Lease | $20 flat rate; $17/lease in 10-packs | Free | Competitor |
| Red Flag Detection | Automated detection of 20 commercial lease risk patterns with severity ratings | Not available as a dedicated feature | Lextract |
| Confidence Scoring | Per-field confidence scores for targeted human review | Not available | Lextract |
| Data Export | JSON, Excel, Word, PDF exports for PMS and financial model import | No structured export; summary text only | Lextract |
| Field Coverage | 126 curated fields covering all standard commercial lease data points | Variable; focuses on summary-level terms, not full structured extraction | Lextract |
| Processing Time | Under 3 minutes per lease | Under 1 minute (summary generation) | Tie |
| Portfolio Workflows | Structured output ready for bulk import into Yardi, MRI, Excel, or Airtable | Not designed for portfolio-scale workflows | Lextract |
Pricing
Lextract
$20 for a single lease. Volume pricing: $90 for 5 leases ($18 each) and $170 for 10 leases ($17 each). No subscription, no implementation fees.
Kolena
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 $20 per lease Lextract charges is the cost of getting data you can actually use.

Who Should Use Each
Choose Lextract if...
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.
Choose Kolena if...
Individual brokers, analysts, or tenants who need a free, quick summary of a lease document without requiring structured output or portfolio-scale workflows.
The Verdict
Kolena fills a legitimate niche: a free AI tool for a fast, casual lease overview. It is the right tool if your goal is a quick read and you have no downstream data requirements.
For any workflow that requires structured data -- loading fields into Yardi, building a rent roll, running due diligence, or tracking escalation schedules -- 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.
