A lease is rarely one clean PDF
A digitally signed lease from this year reads easily. The portfolio you inherit with a building acquisition looks more like this.
Photocopied for twenty years, then scanned
Every landlord's form puts the rent somewhere else
Rent changed in pen and initialled at signing
The lease, its amendments and an SNDA in one scan
Rent steps in an exhibit, the CAM cap in a side letter
Someone reads every page and types the rent, dates and options into a system, and a missed renewal notice date costs the term.
Unstract reads each lease and amendment, pulls the terms you name with the clause they came from, checks them against each other, and sends the record to your property management or lease administration system.
Parse the lease, extract the terms, run the intake
LLMWhisperer, Document Studio and Flow each work alone and fit together. Start with the one your lease work needs now and connect the others when the volume calls for it.
Turn any lease or rental agreement into layout-preserved text
Leases arrive as signed PDFs, photocopies of photocopies and phone photos of a page someone initialled. LLMWhisperer reads each one and keeps the layout, so a rent table stays a table, an exhibit keeps its rows, and a handwritten change sits next to the printed figure it replaced.
Send that text to your own LLM, or make parsing the first step of a longer lease process.
Learn more about LLMWhispererGet structured data from every lease and rental agreement
Describe the terms you track, from parties and premises to rent steps, CAM terms and option notice periods, and Document Studio works as a lease agreement data extractor for every landlord's form. Each value comes back as JSON with the clause it came from. A value that disagrees with an amendment or exhibit arrives flagged. Unstract reports what the lease says; whether a clause holds up stays with your counsel.
Deploy it as an API, run it as an ETL pipeline over a folder of leases, or make extraction one step in an orchestrated process.
Learn more about Document StudioRun lease intake end to end, from scan to critical dates
Describe how your team handles a new or acquired lease, and Flow's agents build the workflow: the lease and every amendment, side letter and estoppel are collected, sorted by date, read, and rolled forward so the latest terms win. You approve the workflow once and it runs the same way on every lease, then sends the record and its critical dates to your property management or lease administration system, your accounting and your calendar.
Set the stopping points once: terms that conflict between documents, an exhibit the lease refers to but the file lacks, a clause the extraction cannot read with confidence. Only those leases go to a lease administrator or paralegal, with the page and the reason attached.

Built for the teams who keep leases current
New tenants set up with the right rent, deposit and CAM share from day one, without retyping the lease.
Acquired portfolios read in days, every renewal and termination notice date on the calendar before it can slip.
Each term tied to the clause and page it came from, so review starts from the lease language rather than a summary.
Rent, escalations and recoveries across the portfolio as one dataset, ready for budgeting and the next refinancing.
Less time keying leases, more time on the tenants
Rents and deal terms stay yours
A lease carries the rent you agreed, the concessions behind it and often the tenant's financials attached to the guaranty. Across a portfolio, those terms are the comps a landlord or tenant negotiates against.
- Encrypted in transit and at rest.
- Your documents are never used to train models.
- Access by role, property and document type. Every review and correction is recorded against the lease.
- Retention you set: processed files are deleted on the schedule you choose.
- Self-hosted options are available for owners and law firms that keep lease files inside their own environment.
What leasing and legal teams ask first
LLMWhisperer. Send it a scanned, photocopied or photographed lease through its API and it returns the text with the layout kept, so rent tables, exhibits and initialled changes stay where the lease put them. It also shows where on the page each value came from.
Document Studio deploys an endpoint per document type. POST a lease, get back a JSON record with parties, premises, rent schedule, dates, options and CAM terms, each with its clause. Prefer files to calls? Run the same extraction as an ETL pipeline over a folder or bucket.
Stop reading every page by hand. Name the terms you track once, and every lease comes back in that shape, whichever landlord's form it is on. For a whole portfolio, Flow collects the leases and amendments, puts them in date order and sends only the conflicts to a person.
Look for a platform that reads the document and the extraction as separate steps. In Unstract, LLMWhisperer reads the lease and keeps its layout, Document Studio uses LLMs to turn that text into the fields you named, and Flow's agents run the intake around both. The reading step is an OCR engine built for LLM pipelines, which keeps rent figures tied to the line they sit on.
Yes. The same setup runs as a residential tenancy agreement data extractor: tenant and landlord names, the rental address, rent and due date, deposit, term or month-to-month status, and the signatures. Name the fields once and every tenancy agreement comes back the same way.
Yes. Each addendum is read on its own, so the same extraction works as a lease addendum data extractor. Flow then dates every amendment and carries its changes forward, so the record shows the rent and expiration that apply today and which document set them.
No. Unstract extracts what the lease says and points to the clause it came from. Whether a termination right or a CAM cap is enforceable is a question for your lawyers, and the clause reference takes them straight to the language.
The lease stops in a review queue with both values and the pages they came from. A lease administrator or paralegal picks the right one, corrects it or sends it back, and the decision is recorded against the lease.
Yes. LLMWhisperer reads handwriting alongside printed text and handles skewed, faded and photocopied scans. A rent figure struck through and initialled comes out next to the printed one, so the extraction can take the change and flag it for a look.
Unstract is SOC 2, ISO 27001, GDPR and HIPAA compliant: documents are encrypted in transit and at rest, never used to train models, and kept only as long as you choose. Owners and firms that need it can self-host. See the Trust Center.
Yes. Start for free, upload a lease and an amendment, and see the fields come back. Running intake for a whole portfolio through Flow starts with a consultation, where the workflow is built around your lease forms and your system.
Bring one tenant's lease file to the consultation
The original lease, its amendments, a side letter and the scan nobody likes to open. We read them together and show each term with the clause it came from.
