Lease abstraction software reads a commercial lease and pulls every key term, parties, premises and RSF, base rent, escalations, options, CAM and critical dates, into structured data you can export. LeaseAbstractors abstracts a lease in minutes at high field-level accuracy, with every value linked back to its source page for fast review. Upload a lease below to see the abstract free, no signup required.

A single commercial lease can run 40 to 100 pages of dense legal language. Abstracting it by hand, or paying a service to, ties up skilled people, takes hours per document, and still leaves room for missed dates and mis-keyed numbers.
Reading a lease, finding the right clauses, and typing terms into a spreadsheet takes a trained analyst two to four hours per document. Across a portfolio that is weeks of work.
Outsourced abstraction services bill by the lease and turn work around in days. For an acquisition or an ASC 842 project covering hundreds of leases, the invoice adds up fast.
Renewal windows, termination options, and notice deadlines hide deep in the document. Miss one and a tenant auto-renews, or you lose a right you meant to exercise.
Every figure typed by hand is a chance to transpose a rent number or a square footage. Bad lease data flows straight into your rent roll and accounting.
Two analysts abstract the same lease differently. Without a fixed template, your portfolio data is uneven and hard to compare.
When a number is questioned, you have to find the page in the original lease all over again. Manual abstracts rarely cite their source.
LeaseAbstractors is AI lease abstraction software built for commercial real estate. Upload a lease in any format and the software returns a structured, review-ready abstract in minutes, with each field traced back to the exact page it came from.
Upload a 60-page lease and get a structured abstract back in a few minutes instead of a few hours. Process one document or a whole batch.
Parties, premises and rentable square feet, commencement and expiration, base rent and escalations, renewal and termination options, CAM and recovery terms, and security deposit.
Native PDFs, scanned copies, faxes, and photographed pages. OCR plus AI handles decades-old leases and poor-quality scans.
Every extracted value links back to the page and clause it came from, so your team verifies in seconds instead of re-reading the lease.
Download clean Excel and CSV, push JSON, or pull abstracts through the API into Yardi, MRI, or your lease administration system.
Bulk-upload hundreds of leases for an acquisition, audit, or ASC 842 project and get consolidated, consistent output.
Three steps from a raw lease document to structured, exportable data.
Drag in a PDF, scan, or photo of any commercial lease, or bulk-upload a folder of them. No template building required to start.
Tip: Start with the live demo above, no signup needed.
The software runs OCR to read the document, then uses language models to find and extract every key business and legal term into a structured abstract.
Check the flagged fields against their source pages, then export to Excel, CSV, or JSON, or send the data straight to your system through the API.
Any team that has to turn leases into data uses abstraction software to do it faster and more consistently.
Build rent rolls and track critical dates across the portfolio without manual data entry.
Abstract leases for due diligence, offering memoranda, and lease comps in minutes during a deal.
Get clean, consistent abstracts ready for your lease admin system or legal review.
Pull rent, term, and recovery data for underwriting and ASC 842 lease accounting.
The best lease abstraction software for your team depends on what you abstract and how much of it. Check field coverage first: does it capture options, co-tenancy, and recovery terms, or just rent and dates? Our commercial lease abstract template lists every field a complete abstract should include. Then look at how it handles scanned and photographed leases, whether every value is linked to its source page for review, and how the data leaves the tool, whether to Excel, CSV, JSON, or an API. For high-volume work like acquisitions and ASC 842 projects, confirm it supports bulk lease upload with consistent, consolidated output. If your system of record is Yardi, check how to abstract leases for Yardi Voyager.
If you are weighing software against an outside abstraction service, compare them on cost per lease, turnaround time, and who keeps control of your documents. Our breakdowns of abstraction services vs software and manual vs automated abstraction walk through the trade-offs with real numbers so you can pick the right approach. If you want to see how the work is done end to end, our guide to the lease abstraction process step by step covers it, and our overview of lease abstraction services compares outsourcing to software.

Talk to our teamLease abstraction software is a tool that reads a lease document and extracts its key business and legal terms, such as parties, rent, term dates, options, and CAM, into structured data. Modern versions use AI and OCR to do this automatically in minutes instead of hours of manual reading.
AI lease abstraction works in layers: OCR converts scanned or PDF pages into text, natural language processing identifies clauses and entities, and large language models reason about how the provisions fit together. The software maps each value to a structured field and links it back to its source page.
On standard fields like parties, dates, and base rent, leading lease abstraction software reaches 95 percent or higher accuracy. Accuracy drops on unusual or heavily negotiated clauses, which is why good tools flag low-confidence fields and link each value to its source so a person can verify it quickly.
Most lease abstraction software is priced by volume, either per lease or as a monthly plan with a document allowance. That is usually far cheaper than outsourced abstraction services, which commonly charge $150 to $500 per lease. Check our pricing page for current plans and limits.
It extracts the terms that drive lease management and accounting: parties and guarantors, premises and rentable square footage, commencement and expiration dates, base rent and escalations, renewal and termination options, CAM and operating expense recoveries, security deposit, and assignment and sublease rights.
Yes. Quality lease abstraction software combines OCR with AI, so it can read native PDFs, scanned copies, faxes, and even photos of lease pages. It handles older, lower-quality scans that plain text-extraction tools choke on, though a very poor image may need a clearer copy.
It depends on volume and control. Software returns abstracts in minutes, keeps your leases in-house, and costs less per lease, while a service hands off the work entirely. Many teams use software for speed and scale and reserve outside help for unusually complex leases.
You can export abstracts to Excel and CSV for spreadsheets and lease administration systems, JSON for developers, or pull the data through an API into platforms like Yardi or MRI. The structured output is ready to import without re-keying.
Lease abstracting software does the same job a human lease abstractor does, reading a commercial lease and pulling its key terms into a structured abstract, but in minutes instead of hours. The terms lease abstract software, lease abstracting software, and AI lease abstractor all describe the same category: a tool that abstracts leases automatically and links each value to its source page for review.
Automated commercial lease abstraction is the use of AI and OCR to read a commercial lease and its amendments and return the key terms as structured data in minutes, rather than the 4 to 8 hours a manual abstract takes. A complete abstract covers six areas: general lease information, financial terms, amendment history, critical dates, key clauses, and operating expense recoveries.
