HOW IT WORKS
How to abstract a commercial lease, from PDF to a source-linked abstract
Lease abstraction is the work of pulling the terms that matter out of a long commercial lease and into a structured chart. Leaseabstracts does the copying. You upload a lease, the AI reads every page and locates the clauses, you review a source-linked and confidence-scored abstract, and you export to a spreadsheet you own. Here is the full process.

DEFINITION
What is lease abstraction?
Lease abstraction is the process of reading a commercial lease and pulling its key business terms, such as dates, rent, escalations, options, CAM, deposits, and critical clauses, into a short structured summary called a lease abstract. It replaces a long contract with a chart your team can sort, compare, and act on without re-reading the whole document.
Done by hand, it takes a trained analyst three to eight hours per lease and the output is only as reliable as the transcription. Done with Leaseabstracts, the AI extracts the same fields in minutes, links every value to its clause, and scores its own confidence, so a person verifies in seconds instead of transcribing for hours. See critical dates, the rent schedule, and key clauses for the fields it pulls.
THE PROCESS
How to abstract a commercial lease in four steps
Each step is automated, but you stay in the loop. The AI does the reading and copying; you keep the judgment and the final approval.
Upload a lease PDF
Drop in a commercial lease, digital or scanned.
Drag in the executed lease, an amendment, or a full file with exhibits. Office, retail, and industrial leases are all handled, and there is no page limit on a single document. Scanned and image-based PDFs run through OCR first, so a decades-old lease that arrived as a photocopy reads just as cleanly as a freshly typed one.
AI reads all pages and locates the clauses
It works across the whole document, not just the first few pages.
The AI reads every page, follows defined terms back to their definitions, and locates the clauses that drive money: the rent schedule, escalation method, renewal and termination options, CAM and recoveries, the security deposit, and the critical-date deadlines. It reconciles cross-references between the base lease and its amendments instead of stopping at the first mention.
Review the structured abstract
Source-linked and confidence-scored, so you verify in seconds.
You get a structured abstract of 200+ fields instead of a 70-page document. Every field is source-linked: click a value and jump to the exact page and clause it came from in the original PDF. Every field also carries a confidence score, so you know which entries the AI is certain about and which to double-check before you rely on them.
Export to Excel, PDF, or your system
A spreadsheet you own, or a Yardi and MRI-mapped file.
Once you have approved the abstract, export it to Excel (XLSX), CSV, or a formatted PDF. For teams running a system of record, a Yardi and MRI-mapped export drops the abstract in without re-keying or reformatting. The output is yours: no migration, no lock-in, and no per-seat enterprise contract.
VERIFY, DO NOT TRUST
Every field is linked to its source clause
The abstract is not a black box. Each value carries a reference back to the exact page and section of the original PDF where the AI found it. Click a renewal date and the source clause opens. This is the difference between a number you have to take on faith and one you can defend in an audit, a CAM dispute, or an acquisition review.
PER-FIELD CONFIDENCE
Each field is scored High, Med, or Low
Not every clause is written clearly. A confidence score tells you where to spend your review time, so you skim the certain fields and read the ambiguous ones. It is how the software turns hours of line-by-line checking into a few minutes of targeted verification.
Stated plainly in one clause. The AI found an unambiguous figure or date and matched it to its source. Skim and approve.
Derived or assembled from more than one clause, such as a rent schedule built from a base figure plus a stepped escalation. Worth a quick check against the linked clauses.
Ambiguous drafting, a missing exhibit, or conflicting amendment language. Flagged so you read the clause yourself before relying on the value.
HUMAN REVIEW
The AI does the copying. You keep the judgment.
Leaseabstracts is built to be checked, not blindly trusted. Nothing is relied on until a person approves it.
Review before export
The abstract opens in a review state. You read it, edit any field, and approve it before a single value leaves the tool.
Edit any value inline
Disagree with an extraction? Correct it in place. Your edit overrides the AI and travels into every export.
Low scores are flagged
Fields the AI is unsure about are surfaced, not hidden, so the ambiguous clauses get a human read.
Source on every field
Each value links to its clause, so review is a glance at the page, not a re-read of the lease.
Your data stays yours
Documents are encrypted in transit and at rest and are never used to train models. See our security page.
No system to migrate to
The output is a file you own. There is no system of record to adopt and no data to hand over.
