Built for commercial leases. Here is what comes back from every document you upload.
Each extracted term carries the page it came from. Click it and the PDF opens at that page, so checking a renewal option takes seconds instead of a reread.
A field the model could not fill is marked no value found. A value it could not tie to a page is marked no source page. Those are the only fields you must open.
Upload the base lease with its amendments and extension letters. Later documents that change rent, term or options are reflected and both sources are cited.
Renewal, termination and expansion notice deadlines come back as dates, not as a sentence you still have to count backward from.
Download the reviewed terms to Excel, CSV or JSON and hand them to the deal team, the lender or the lease accounting system.
Review up to 50 leases in one upload on Plus, or connect the REST API on Pro so leases from your document store are read as they arrive.
The model does the full read. A person clears the flags.
Scanned or native PDF. Add the amendments, commencement letter and any extension so the review reflects the current deal.
Rent, escalations, CAM, options, notice windows and clause text return in one fixed layout, each with its page.
Open only the fields marked no value found or no source page, plus anything that moves money, and confirm them on the cited page.
Export the reviewed abstract, attach it to the deal file, or push it to your lease system through the API.
What these tools read, where they stop, what they cost and how teams use them on real deals.
Short answer: AI lease review software reads a commercial lease and its amendments in a few minutes and returns the business terms a reviewer needs (rent and every escalation, CAM and expense recoveries, renewal and termination options, notice windows, assignment and guaranty language) as structured fields, each tied to the page it came from. The software does the full read. A person then checks only the fields that are flagged or that move money. It does not replace a commercial real estate attorney, but it removes most of the hours spent reading and retyping.
A manual review of a commercial lease is mostly reading. An analyst, paralegal or associate goes page by page, finds the rent schedule, the escalation basis, the renewal option and its notice period, the operating expense definitions and the assignment clause, and types each one into a summary or a spreadsheet. On a 60 page office lease with three amendments that is typically 4 to 8 hours of careful work, and the amendments are where most mistakes happen, because a 2019 extension letter quietly changes the rent that the 2014 base lease still shows.
AI lease review software reverses that order. It reads the whole lease set first and returns every term in a fixed layout. Instead of reading 60 pages to find 40 facts, the reviewer starts with the 40 facts and opens the lease only where a fact needs confirming. That is the whole value: the review becomes a verification pass instead of a first read.
Two features decide whether that verification pass is fast or slow. The first is the page citation. A term without a source is a term you have to hunt for again, so every value our review returns carries the page it came from, and clicking it opens the PDF at that page. The second is honest flagging. Our review marks a field no value found when the model could not fill it, and no source page when it returned a value it could not tie to a page. Those flags are the short list a reviewer must open. We do not show a made up confidence percentage, because a number like 0.98 from a language model is not a calibrated probability and it tends to make people skip checks they should do.
The honest answer depends on who is reviewing and how many leases are in front of them. The market splits into four groups, and the table above compares the tools in each on what the vendors publish themselves.
A small business owner about to sign a single lease wants to know what is dangerous in it. Per document tools built for that moment produce a risk report with red flags and suggested redlines and charge per document. BizLeaseCheck, for example, prices a full report at 20 to 50 dollars one time depending on the document type. That is the right shape of product for a one off negotiation. It is the wrong shape for a team that needs the same 40 fields from 30 leases in one consistent export.
Acquisition teams, lenders, lease administrators and the paralegals supporting them do not need a danger score. They need every lease in a portfolio read the same way, with amendments applied in order, every value cited, and an export that lands in Excel, Argus, Yardi, MRI or an ASC 842 tool without retyping. This is where dedicated lease review and abstraction software earns its cost, and it is the job our tool is built for. You upload one lease or a batch of up to 50 files on the Plus plan, and you get the same field layout back for every lease in the set.
Large owners that want the review done for them, with people checking the AI, buy a service tier. Prophia Essentials is the clearest example: its pricing page describes it as a per tenant annual subscription with AI plus CRE expert review across 215 fields, priced on a quote. Its lighter Prophia Abstract product is AI only, pulls about 35 terms, and is described on the same pricing page as free. We break the two down in our Prophia pricing comparison, and the Prophia alternative page covers when a self serve tool is the better fit.
If the leases already live in MRI, MRI Contract Intelligence adds AI extraction of dates, dollars and clauses with a human review step inside the MRI product family, and MRI says AI abstraction can cut lease review time by 50 to 75 percent. Our MRI lease abstraction alternative page compares that route with a self serve tool. Law firms that review many contract types often use a general contract review platform instead. Kira, long the best known of those, now resolves to the Review product on the Litera site. Both are sold after a demo, with no price published.
On the reading and extraction work, close to it, and much faster. Published comparisons of AI abstraction tools put field accuracy on standard commercial terms around 92 to 98 percent, against 95 to 99 percent for a trained human abstractor working carefully. The gap is concentrated in specific places: poor scans and faxed pages, handwritten interlineations, rent schedules split across exhibits, and drafting that is genuinely ambiguous. Those are also the places where a human reviewer slows down and makes mistakes, which is why the useful question is not which one is perfect but how fast the errors get caught.
Where AI does not match a person is judgment. Software can tell you that the tenant may assign without consent to an affiliate and cite the page. It cannot tell you whether that clause is acceptable for this tenant in this deal. That is the line we draw on every page: the software does the reading, a person makes the call. Our AI lease abstraction accuracy guide walks through the numbers and how to test a tool on your own leases.
A review that only returns parties, dates and base rent is a summary, not a review. For commercial leases the set that matters to a US buyer, lender or landlord looks like this:
Our review returns these as fields, and the full clause text where a summary would lose meaning. The lease clause extraction page lists the clause level fields in detail, and critical date extraction covers how every notice window comes back as a date you can load into a calendar.
Acquisitions. A buyer gets a data room with 40 leases and two weeks of due diligence. Running the set through review on day one turns the rent roll check into a comparison exercise: the rent, term and options in the leases against the rent roll the seller provided, with every difference traced to a page. The analyst time goes to the mismatches, not to reading.
Lending. A credit team underwriting a loan on a multi tenant property needs the same facts from every lease, plus the SNDA and estoppel terms. A consistent export means the lease summary in the credit memo is built from cited data rather than copied by hand.
Lease administration onboarding. A new portfolio arrives and every lease has to go into Yardi, MRI or a lease accounting system. Review first, then import the reviewed fields, so the system of record starts clean.
Legal support. Paralegals supporting a real estate group use the cited abstract as the first draft of the lease summary and spend their time on the clauses the attorney needs to see. Our lease abstraction for paralegals page shows that workflow.
For one lease and a quick question, a general assistant is fine. The trouble starts with volume and with proof. A chat answer has no fixed field layout, so the tenth lease comes back structured differently from the first. It rarely gives a page you can click to confirm a number. It can miss an amendment that sits in a separate file. And on several consumer plans the content you paste can be used to train the model unless you opt out, which matters when the lease is under an NDA. We compared the two side by side in ChatGPT lease abstract vs abstraction software.
Three pricing models dominate. Per document tools charge a one time fee per report, which suits a single negotiation. Enterprise platforms and managed services quote an annual contract after a demo, often priced per tenant, per lease or per location. Self serve software publishes a monthly plan. Ours is on the pricing page: Starter at 49 dollars a month includes 2,500 Base pages or 500 Pro pages with a 25 page cap per document, and Plus at 149 dollars a month includes 10,000 Base or 2,000 Pro pages, unlimited pages per document, bulk upload of 50 files, custom templates and 3 seats. Pro adds the REST API.
The fair way to compare is cost per reviewed lease against what the review costs today. If an analyst spends 4 to 8 hours on a commercial lease with amendments, and the software turns that into a 20 to 40 minute verification pass, the saving per lease is several analyst hours, every time.
The fastest way to judge any of this is to run a lease through the tool at the top of this page and compare the result with your current summary.
Yes, for the reading part. AI lease review software reads a 60 page commercial lease in a few minutes and returns its business terms, dates and clause text with page references. It does not replace a commercial real estate attorney on negotiation or legal judgment. The practical workflow is AI first for the full read, then a person on the flagged and high value terms.
It depends on the job. A tenant negotiating one lease before signing is served by a per document risk report. A team reviewing a stack of leases for an acquisition, a refinancing or an onboarding needs every term cited to a page, amendments applied, and an export. Enterprise owners on MRI can use Contract Intelligence; owners who want a managed service often look at Prophia Essentials.
It can summarize one, but it does not give you a fixed field layout, a page citation you can click, or a consistent export across fifty leases, and on several consumer plans the content you paste can be used for model training unless you opt out. That is why teams with real volume use dedicated lease review software.
On standard commercial fields such as parties, dates, base rent and option terms, current tools typically land around 92 to 98 percent field accuracy, against 95 to 99 percent for a trained human abstractor. Accuracy drops on ambiguous drafting and poor scans, which is why page citations and flagged fields matter more than any headline number.
Pricing models vary. Per document consumer tools charge 20 to 50 dollars for a single report. Enterprise platforms such as MRI and Prophia Essentials quote after a demo. Our plans are published: Starter is 49 dollars a month with a 25 page per document cap, and Plus is 149 dollars a month with unlimited pages per document and 50 file batches.
No. It replaces the hours spent reading and retyping terms, not the judgment about whether a clause is acceptable. Lawyers and paralegals use it to get the whole lease into a structured, cited form first, then spend their time on the clauses that need advice.

Ask a questionEach plan includes a monthly allowance of pages, and the number you get depends on which AI model you choose at extraction time. Base AI processes pages faster; Pro AI delivers the highest field-level accuracy. Your allowance resets on your billing anniversary each month, unused pages do not roll over. A typical commercial lease runs 20 to 60 pages including amendments, so the Starter plan's 2,500 Base AI pages cover roughly 40 to 120 leases a month.
Once your included pages are used up, extraction pauses until the next billing cycle. You can upgrade your plan at any time mid-month, the higher allowance kicks in immediately and you are only charged the prorated difference for the remainder of the period.
Yes. You can switch from monthly to yearly billing at any renewal date to lock in the 50% discount. If you switch mid-cycle, the new rate takes effect at the start of your next billing period. Annual plans are non-refundable after the 14-day cancellation window.
All plans export to Excel XLSX and CSV. Plus adds QuickBooks (QBO) export and financial reports. Pro unlocks JSON output via REST API so you can push structured data directly into any ERP, RPA platform or internal system.
We do not use your documents to train or improve our own models, and files are encrypted in transit (TLS 1.2+) and at rest (AES-256). Extraction runs through a third-party model provider, so review their terms if your policy requires a contractual no-training commitment. You control retention: documents can be deleted from the workspace at any time, and we will remove everything on request.
