BUYER'S GUIDE
Best AI Lease Abstraction Software for CRE (2026)
Updated October 2026 · 10 min read
TL;DR
AI lease abstraction turns a stack of leases and amendments into structured data you can check against the source clause. Landlords with a portfolio should look first at Prophia, which pairs AI with expert review and stacking plans. Occupiers who also need lease accounting should look at Visual Lease or LeaseQuery (FinQuery). Lenders and buyers doing diligence can send leases to Clik.ai's 24-hour service. Abstria is a new self-serve tool with a free trial and 200+ fields traced to their clauses. LeaseLens is a different job: a $75 risk review of one lease for a tenant.
A lease abstract is the one-page (or two-hundred-field) summary of what a lease actually says: parties, term, rent schedule, escalations, recoveries, options, critical dates and the clauses that carry risk. Abstracting by hand takes hours per lease, which is why acquisitions teams, lenders and lease administrators have long outsourced it. AI has changed the economics. The tools below read a lease and its amendments in minutes and link each extracted value back to the clause it came from, so a reviewer checks rather than types.
The vendors split into three groups. Some sell a platform where abstracts become living lease data for a portfolio. Some sell abstraction as a service with people checking the AI's work. And a few sell a self-serve tool you run yourself. Which you need depends less on the AI than on what happens to the data afterwards.
Things to know before the list:
- Source links are the feature that matters. Every tool here links extracted values to the source text. Without that, you are trusting the AI rather than checking it.
- Decide who reviews. Prophia, Visual Lease and Clik.ai put people on the review step. Abstria and LeaseLens leave review to you. Accuracy figures on vendor sites are their own claims.
- Amendments are where abstracts go wrong. A base lease read in isolation misses later rent changes and option exercises. Check that a tool reads amendments together with the original and shows what changed.
- Abstraction is not legal advice. These tools speed up review; they do not replace counsel on a disputed clause.

The 6 Best AI Lease Abstraction Tools
1. Prophia
Best for: Landlords and operators who want abstracts kept current across a portfolio
Prophia is the most complete landlord-side option. AI extracts lease data, then Prophia's CRE experts audit it before delivery, and the result is a living abstract where each value links back to the source text across leases, amendments and renewals. Its Essentials plan covers 215 fields.
The abstracts feed everything else Prophia does: stacking plans that update themselves, critical date tracking, lease benchmarking, CAM and rent roll reconciliation, a Yardi audit that compares your system of record with the leases, and an MCP connector so ChatGPT, Claude or Gemini can query the data. Founded in 2018, it says it covers 720 million square feet across 5,852 buildings, and names RXR as a customer. It is a subscription priced per tenant, so it suits ongoing portfolio work more than a one-off diligence project.
What's good
- AI plus CRE expert audit on every abstract
- Values linked to the source lease language
- Stacking plans, critical dates and Yardi audit built on the data
- Unlimited users
What's not
- No published pricing
- Annual subscription, not a one-off service
- Landlord-focused, not built for occupier lease accounting
Pricing: Prophia Essentials is priced per tenant on an annual subscription; Prophia Portfolio is an annual add-on. Pricing on request.
2. Visual Lease
Best for: Corporate occupiers that need abstraction, lease administration and ASC 842 accounting together
Visual Lease, now part of CoStar Group, is a lease administration and lease accounting platform for organizations that rent their space, with compliance for ASC 842, IFRS 16 and GASB 87. It now offers AI lease abstraction powered by CoStar's Lease LLM, with fields tied back to the lease language and review by what it describes as more than 50 dedicated attorneys and expert abstractors.
The appeal is that abstraction lands directly in the system that runs critical dates and produces the accounting. The trade-off is that this is enterprise software: pricing is by request, implementations take time for large portfolios, and it is overkill if all you need is a stack of abstracts for a deal.
What's good
- Abstraction feeds lease admin and lease accounting in one system
- Human review by attorneys and abstractors
- Covers real estate and equipment leases
- Backed by CoStar Group
What's not
- Enterprise pricing only
- Long implementations for complex portfolios
- More than a deal team needs
Pricing: Request pricing from the vendor.
3. Clik.ai
Best for: Lenders and investors who want abstracts delivered for a deal, fast
Clik.ai is best known for AI underwriting, but it also runs an AI lease abstraction service. You send the original lease with its amendments and side letters, and you get back a standardized abstract covering 50+ fields across 12 sections, where every data point references the source lease section and page. A clause-by-clause review and QA pass sit on top of the AI, and the stated turnaround is 24 hours.
For a lender or buyer working through diligence, that is a practical middle ground between hiring abstractors and running a tool yourself, and it pairs naturally with Clik.ai's underwriting product. It is a service rather than a portfolio platform, so there is no ongoing lease management, and pricing is not published.
What's good
- 24-hour turnaround on a standardized abstract
- Every field cited to section and page
- Human QA on top of AI extraction
- Fits alongside Clik.ai underwriting
What's not
- A service, not a lease management platform
- Fewer fields than portfolio platforms
- No published pricing
Pricing: Pricing on request.
4. LeaseQuery (FinQuery)
Best for: Finance teams whose main lease problem is ASC 842 accounting
LeaseQuery, now FinQuery, is lease accounting software first. Its lease accounting product includes automated lease abstracts with AI-assisted data abstraction and AI-enabled document extraction, so lease data flows straight into journal entries and disclosures for ASC 842, IFRS 16 and GASB 87.
That makes it a sensible choice when the people asking for abstracts are in accounting, and its LeaseGuru trial lets you enter your first two leases free. It is not a standalone abstraction product, though, and teams that need deep operational lease data or landlord-side analytics will find more in Prophia or Visual Lease.
What's good
- Abstraction built into lease accounting
- Covers ASC 842, IFRS 16 and GASB 87
- First two leases free on LeaseGuru
- Extends to prepaids and accruals
What's not
- Not sold as standalone abstraction
- Accounting focus, lighter on lease operations
- Quote-based beyond the trial
Pricing: Quote-based; LeaseGuru lets you enter your first two leases free.
5. Abstria
Best for: Attorneys and diligence teams who want to abstract leases themselves, with every field traced (new)
Abstria is a new tool from Al Rafay Consulting, a Microsoft partner based in Illinois, and it shows the newness: few independent reviews and a thin track record. What it does is well designed. It reads leases, amendments, SNDAs, estoppels, LOIs and acknowledgements, extracts more than 200 fields per lease, and hyperlinks each one to the page and clause it came from. Review happens in a dual-panel editor beside the PDF, amendments are compared against the original so changed values sit side by side, and a portfolio assistant answers plain-language questions such as which leases expire in the next 90 days.
Abstracts export to PDF or Word, and there are admin and contributor roles with an audit trail. A self-serve free trial is available; paid plans need a sales conversation, and SSO and API access are Enterprise only. Its accuracy and speed figures are vendor claims, so run leases you have already abstracted through it first.
What's good
- 200+ fields, each linked to its source clause
- Reads amendments, SNDAs and estoppels and shows deltas
- Self-serve free trial
- Audit trail and review workflow
What's not
- New, with a thin track record
- No published paid pricing
- No human review included
Pricing: Free trial; paid and Enterprise plans on request.
6. LeaseLens
Best for: Tenants and tenant-rep brokers checking one lease before signing (new)
LeaseLens does a different job from the rest of this list. It is not a portfolio abstraction tool; it is a risk review of a single commercial lease from the tenant's side. Upload a retail, office, industrial or NNN lease and you get a free preview, then a $75 report that runs the lease against a 15+ category checklist and covers risk flags rated by severity, the rent schedule, CAM, personal guarantee exposure, critical dates and negotiation priorities, quoting the clause behind each finding.
A $199 a month plan gives brokers unlimited reports. The site says it was established in 2026 and names no operator, so it has little track record, and it states plainly that its reports are not legal advice. For a small tenant about to sign, it is an inexpensive second read before paying a lawyer.
What's good
- Clear per-report price with a free preview
- Findings quote the clause and suggest negotiation asks
- Unlimited plan for tenant-rep brokers
- Free reprocessing if a material clause is missed
What's not
- Single-lease review, not portfolio abstraction
- New, with no named operator
- Not legal advice
Pricing: $75 per report; $199/month unlimited for brokers and teams.
How to Choose
Decide what happens to the data after it is extracted, then pick the tool built for that.
- Choose Prophia if you own or operate a portfolio and want reviewed abstracts that stay current and drive stacking plans, critical dates and Yardi checks.
- Choose Visual Lease if you are a corporate occupier and abstraction needs to feed lease administration and ASC 842 accounting.
- Choose LeaseQuery (FinQuery) if the request comes from accounting and the abstract mainly needs to produce journal entries and disclosures.
- Choose Clik.ai if you are a lender or buyer on a diligence clock and want cited abstracts back within a day.
- Choose Abstria if you are an attorney or diligence team that prefers to run abstraction yourselves, with every field traced, and can accept a new vendor.
- Choose LeaseLens if you are a tenant or tenant-rep broker who needs a quick risk read of one lease, not an abstract.

How We Researched This Guide
We worked from each vendor's own website, pricing page and product documentation, checked in October 2026, and only included tools listed in this directory. We did not run these products on our own leases. Prices are the vendor's published rates; where a vendor does not publish prices we say so. Accuracy, speed and coverage figures are the vendors' claims and are labeled that way. No vendor paid for placement.
Frequently Asked Questions
What is AI lease abstraction?
Software that reads a lease and its amendments and extracts the key terms (parties, dates, rent schedule, escalations, recoveries, options and risk clauses) into structured fields, usually with a link from each value back to the clause it came from. It replaces hours of manual summarizing per lease.
How accurate is AI lease abstraction?
Vendors claim high accuracy (Prophia and Clik.ai cite 99%, Abstria 95% or more), but those are their own figures. The practical safeguards are source links on every field and a human review step, either the vendor's (Prophia, Visual Lease, Clik.ai) or your own.
Should I use software or an abstraction service?
If you need abstracts once, for a deal, a service such as Clik.ai's 24-hour abstraction is simpler. If lease data has to stay current and drive operations or accounting, a platform such as Prophia, Visual Lease or FinQuery makes more sense. Self-serve tools like Abstria suit teams that want control and will do the review themselves.
How much does AI lease abstraction cost?
Most vendors quote on request. Prophia prices Essentials per tenant on an annual subscription, FinQuery's LeaseGuru lets you enter your first two leases free, Abstria offers a free trial, and LeaseLens publishes $75 per single-lease report or $199 a month for unlimited reports.
Can AI lease abstraction handle amendments?
The better tools read amendments together with the original lease. Abstria compares amendments against the base lease and shows changed values side by side, Prophia's living abstracts span leases, amendments and renewals, and Clik.ai takes amendments and side letters as inputs.
