vs. AI Legal Platforms
AI is probabilistic. Lease math can't be.
AI legal platforms cover contract review and drafting assistance well. But lease math — percentage rent, CAM reconciliation, rent escalations — has to be deterministic, not probably right.
AI is improving fast. We take it seriously.
AI legal platforms represent the fastest-moving category in legal technology. Spellbook, Harvey AI, and Luminance are genuinely sophisticated tools used by thousands of legal teams. They excel at contract review, research, and drafting assistance across many document types.
The question is specific: can a probabilistic system reliably calculate a 10-year rent schedule with CPI escalations, percentage rent breakpoints, and pro-rata shares? For a 40-page lease with $50M in aggregate rent obligations, “probably right” isn't good enough.
Deterministic vs. probabilistic
AI platforms predict text. LeasePilot computes results. Both have a role, but they're not interchangeable.
AI Legal Platforms
LeasePilot
- Generates text based on patterns and probabilityComputes results with mathematical certainty
- Suggests clauses that look right but may hallucinateApplies your firm-approved clauses, no hallucination
- Cannot reliably calculate rent escalation schedulesDeterministic CRE calculation engine built-in
- Treats each document independentlyConnected document suite from a single deal record
- Broad coverage across many contract typesDeep CRE expertise in one document type
10+ years of CRE logic, not training data
Not AI predictions. Deterministic business rules encoded over a decade of CRE lease work.
№ 01
Structured CRE data model
Rent schedules, CAM, TI allowances, and percentage rent exist as first-class objects with calculation logic, not text patterns an LLM can approximate.
№ 02
Deterministic calculation engine
Rent escalations, pro-rata shares, and breakpoint calculations are computed with mathematical certainty. No hallucinated numbers, no plausible-looking but wrong math.
№ 03
Connected document suite
Lease to amendments to SNDAs to estoppels, all stay in sync from a single deal record. AI tools treat each document independently.
№ 04
Open API for CRE data
An open API that bridges your operational systems — Yardi, MRI, Salesforce, or your own data layer — and LeasePilot's drafting. AI legal platforms sit on top of documents, not connected to your operational data.
№ 05
Your firm-approved clause library
Clausebook organizes and versions your approved language with one-click insertion. Different from AI-suggested language, which may hallucinate or drift from your standards.
№ 06
AI where it adds value
LeasePilot uses AI for lease abstraction (Extract) and negotiation assistance (Autopilot), where flexibility helps. Deterministic logic handles everything where correctness is non-negotiable.
Where AI platforms are genuinely stronger
LeasePilot goes deep on one document type. AI platforms go wide across many. Many teams use both: LeasePilot for leases and CRE documents, an AI platform for everything else.
- Breadth across many contract types
- Legal research database integration
- Low adoption friction (Word add-ins)
- Market-standard benchmarking (Spellbook)
- Rapid pace of improvement
The calculation gap
Ask an LLM to calculate a 10-year rent schedule with 3% annual escalations, a 6-month abatement, and percentage rent above a natural breakpoint. You'll get plausible-looking numbers; they won't be reliable.
