Automate lease abstraction
Unstract reads the lease and every amendment, side letter and estoppel that followed it, rolls the terms forward, and sends the abstract and its critical dates to your property management or lease administration system.
Trusted by real estate and property teams around the globe
The terms that count are spread across decades of paper
A tenant's real deal is the original lease plus every amendment, side letter and estoppel signed since. Someone reads them all in order, works out which rent and which dates still apply, and keys the result into an abstract by hand.
A lease packet scanned as one file, with no page breaks between documents
A 2009 lease scanned crooked, with a stamp across the rent clause
A base rent the third amendment changed and the abstract never caught
An abstract keyed by hand while a renewal notice date gets closer
An estoppel the lender needs, still waiting on the tenant
A missed amendment or a renewal date nobody diarised turns into rent billed at the wrong rate or an option that lapses before anyone notices.
Unstract reads every document in the lease file, rolls the terms forward through each amendment and builds the abstract with the page each term came from. A lease administrator or paralegal sees only the conflicts.
From the lease file to lease administration, without the keying
Five steps, run on their own for every lease. Parsing by LLMWhisperer, extraction by Document Studio, the whole run by Flow.
Pick up every lease document wherever it lands
Leases, amendments, side letters and estoppel certificates arrive as scans in a property folder, as PDFs from counsel, as downloads from an acquisition data room and as attachments from a lender. Each one is picked up where it arrives and tied to its property, suite and tenant, so the whole history of one lease sits in one record, even when it spans decades.
Nobody has to hunt through shared drives for the 2014 amendment before the abstract can start.
Split the lease packet and date every document in it
A packet scanned as one PDF is split into its documents, and each one is classified (lease, amendment, side letter, estoppel, SNDA) and dated from its execution page. The documents are then put in the order they were signed, so the latest amendment's terms are the ones that carry forward.
An undated side letter is flagged at this step, before its terms can override anything.
Read every lease and amendment, then pull the terms that matter
LLMWhisperer reads each document as text with its layout kept, so a rent schedule stays a table on a crooked 2009 scan and a handwritten initial beside a clause stays beside it. Document Studio then extracts the terms you defined: parties, premises, term dates, the rent schedule and escalations, CAM and tax recoveries, renewal and termination options, notice periods and critical dates.
Every value keeps the document and the page it was read from.
Check each amendment against the lease before anyone relies on it
Terms are rolled forward through each amendment in order, then checked against your standard lease and against the rent roll. A conflict, a missing exhibit or a clause that departs from your standard terms stops in a review screen with each version side by side and the page it came from.
A lease administrator or paralegal decides what the documents mean. Unstract shows what each one says and gives no legal advice.
Open the abstract where lease administration already works
The finished abstract and its critical dates go to your property management or lease administration system, such as Yardi or MRI Software, with a reminder for every option and expiry on the critical-dates calendar. Rent changes go to accounting, and every decision a person made is recorded against the lease.
The abstract shows where each term came from, so the next reader checks a page reference instead of the whole file.

Bring the lease and everything signed since. You see each term with its page, and each conflict held for your team to decide.

Live on one property's leases first
Your team writes no code. The run is set up on leases you already hold and proven on one property before the rest of the portfolio follows.
Book a consultation
We go through a few of your lease files with you: how they are stored, which terms your abstracts carry, and who settles a conflict between an amendment and the lease today.
Built on your leases
The abstract fields, the checks against your standard lease and rent roll, and the connection to your lease administration system are set up on real lease files, old scans included.
Pilot one property, then the portfolio
One property's leases run live first. When the abstracts hold up against the ones your team wrote, the other properties follow with the same review rules.
Built for the people who keep leases current
Rent, recoveries and option dates for every suite in front of you, taken from the latest amendment, not the lease someone filed first.
AI lease abstraction that drafts each abstract with its page references, so the team reviews conflicts instead of keying a whole file.
The conflicts and the clauses that depart from your standard lease, each with the pages that disagree, ready for a decision.
Lease abstraction software for a whole portfolio or an acquisition's data room, with every abstract built the same way.
Abstracts drafted in minutes, conflicts caught before they cost rent
Safe for the rent and deal terms in every lease
Leases record what each tenant pays, the concessions each one negotiated and what they owe you through the term. Across a portfolio, that is your income and your negotiating position, written down in one place.
- Encrypted in transit and at rest.
- Leases and abstracts are never used to train models.
- Access by role, property and document type, with every review and correction recorded against the lease.
- Retention you set: processed lease files are deleted on the schedule you choose.
- Self-hosted deployment for owners and REITs whose controls keep lease documents inside their own environment.
What lease administrators ask before they start
Check every value against its source. LLMWhisperer reads each page with its layout kept, so a rent table on an old scan stays a table, and Document Studio extracts the terms you defined with a confidence score and the page each came from. Flow then checks every amendment against the lease, your standard terms and the rent roll. A low-confidence read or a conflict stops for a person instead of landing in the abstract.
Automated lease abstraction gives your compliance and lease accounting teams the same record every time: term dates, the payment schedule, renewal and termination options and every critical date, each with its page. Flow sends it to your lease administration system and sets a reminder for every option and expiry. Your team decides how a term is treated; Unstract supplies what the documents say.
Yes. A packet scanned as one file is split into the lease, each amendment, side letters, estoppels and SNDAs, and each document is dated from its execution page. Exhibits stay attached to the document they belong to, and a packet with a missing exhibit is flagged.
A lease abstract is a summary of the terms you act on: parties and premises, term dates, the rent schedule and escalations, CAM and tax recoveries, renewal, termination and expansion options, notice periods and critical dates. You choose the fields, and Unstract fills them from the latest document that governs each term.
A person on your team. Unstract holds the lease with both versions side by side and the page each came from, and a lease administrator or paralegal confirms the term. Unstract reports what the documents say and gives no legal advice.
Unstract is lease abstraction software your team runs. Abstracts are built in your own account, and your lease administrators review the conflicts. Nobody outside your team reads your leases.
Your property management or lease administration system, such as Yardi or MRI Software, through its import or API, plus accounting and a critical-dates calendar. A copy can also go to a shared drive or a database. Flow sends it as part of the run, so nothing is keyed again.
Unstract is SOC 2, ISO 27001, GDPR and HIPAA compliant. Lease files are encrypted in transit and at rest, never used to train models, and kept only as long as you choose. Owners that keep documents in-house can self-host. Your auditors can read the control list in the Trust Center.
