Lease abstraction software
Every abstracted term comes with its source
LeaseBrain is AI lease abstraction software for commercial lease document chains. It structures material terms, connects each value to its source page and clause, computes the dates your team needs to watch, and keeps uncertain fields visible for human review.
The renewal option remains in effect, with notice measured from the expiration date as amended by this document.
Structured field
- Field
- Renewal option
- Current source
- Amendment 02, page 4
- Review state

What gets abstracted
A current-state record of the lease, not another loose summary

Base rent, escalations, and operating expense provisions
Renewal, termination, expansion, and purchase options
Notice requirements and computed notice windows
Use, exclusivity, assignment, and subletting provisions
Security deposits, guarantees, and amendment history
The control path
Extract, cite, resolve, compute, review
01
Extract
Material fields are structured consistently across the portfolio.
02
Cite
Each stored value carries its source page and clause text.
03
Resolve
Amendments update only the fields they actually change.
04
Compute
Relative notice language becomes concrete calendar dates.
05
Review
Ambiguous or low-confidence fields remain visible for a person.

Questions
Before you choose a lease abstraction tool
What makes citation-backed lease abstraction different?
Every abstracted value points to the document, page, and clause that supports it. A reviewer can check the source language without searching through the entire lease again.
How does the software handle lease amendments?
LeaseBrain orders the document chain and applies changes field by field. Later language controls the terms it changes, while terms it does not address remain in force.
Does software remove human review?
No. Routine extraction and date math move through the system, while low-confidence or ambiguous fields stay visible for human review with the source clause beside them.
How is LeaseBrain priced?
Pricing is discussed after a short requirements review of the portfolio, documents, and workflow. Book a meeting to walk through the fit and discuss price.
