An AI-powered search and research assistant that can analyze uploaded documents. Useful for quick lease questions with cited sources, but lacks structured extraction, confidence scoring, and CRE-specific features.
Lextract wins 8 of 10 feature categories
Based on features, pricing, and workflow integration
Perplexity AI has carved out a unique position as an AI research assistant that cites its sources. Upload a document, ask a question, and Perplexity provides an answer with references - a workflow that appeals to professionals who need verifiable information. For quick lease research questions ("What is a standard CAM cap in Class A office?"), Perplexity delivers well-sourced answers faster than traditional search.
But Perplexity is a research tool, not an extraction tool. It excels at finding and synthesizing information but cannot extract a consistent set of structured fields from a lease document, score confidence per field, detect CRE-specific red flags, or export data into property management systems. The use cases are complementary, not competing: Perplexity helps you understand market context; Lextract extracts the data from the lease itself.

$15 for a single lease extraction. Volume pricing: $65 for 5 leases ($13 each) and $120 for 10 leases ($12 each). No subscription.
Free tier with limited daily queries. Perplexity Pro costs $15/month for unlimited queries, file uploads, and access to advanced models. Enterprise plans available.
Perplexity Pro at $15/month is cost-effective for general research. But it cannot replace a purpose-built extraction tool - you would still need to manually extract, structure, and verify every field from the AI's prose output. For lease abstraction specifically, the labor cost of using Perplexity as a makeshift extraction tool far exceeds Lextract's per-lease pricing.
CRE professionals who need structured, repeatable lease data extraction for portfolio management, due diligence, and PMS integration.
Market research and contextual lease analysis: understanding whether specific terms are market-standard, finding comparable lease structures, and getting cited answers about CRE concepts and regulations.
Lextract is the stronger choice for structured lease data extraction. Perplexity may make sense as a research companion -- understanding whether a 5% CAM cap is below market for Class A suburban office, finding comparable lease structures, getting cited answers about CRE concepts -- and those are tasks Perplexity handles genuinely well. But for the majority of CRE professionals who need structured data from the lease itself, Perplexity is a research tool, not an extraction tool.
Lextract takes a lease PDF and returns 126 structured fields with confidence scores and red flag detection. These are complementary workflows. Use Perplexity to research market context. Use Lextract to extract the actual data from the lease itself.
