Who invented Contract Superintelligence?
Jim Vanderpool, a practicing Tennessee attorney and the founder of ClosingStart and Realestart, is the inventor of Contract Superintelligence, which he started working on in 2017.
Before there was AI, there was CSI.
As of October 2026.
He is not a computer programmer. He had never written a line of code before 2017. He is a lawyer, and it turns out that with legal training and more than 15,000 real estate contracts behind you, you start to see patterns: you know what the next page is going to say before you turn it. He taught himself regex, became, in his words, nominally proficient at Python, and taught a computer to find the patterns.
Contract Superintelligence, in plain English: Contract Superintelligence (CSI) is technology invented by Tennessee attorney Jim Vanderpool that reads your real estate contract and tells you, in about five minutes, exactly how much money you'll bring to closing as a buyer or walk away with as a seller. Every number shows you where it came from in your contract, and you can ask it questions about your contract in plain English.
The dates
- 2002. Vanderpool Law starts giving buyers and sellers their numbers the week the contract arrives, by hand.
- September 1, 2017. Work began, at Vanderpool Law in Franklin, Tennessee.
- April 2018. The first instant settlement statement produced with no human input.
- 2019. Programming begins on the two companies built on it: ClosingStart, for consumers and realtors, and Realestart, for the title industry. Both stay inside the office for years.
- 2024 to 2025. He decides everyone should have it, not just his clients.
- 2026. Contract Superintelligence runs inside ClosingStart and Realestart and powers the Vanderpool Law instant settlement statement.
For the technical crowd: how it works, stage by stage
What follows is the engineering view of Contract Superintelligence, one stage at a time. It is a proprietary system built for a single domain, residential real estate conveyancing, that both understands documents and does the arithmetic. Jim R. Vanderpool, a Tennessee attorney, began development on September 1, 2017, and in April 2018 it carried a contract all the way to a finished settlement statement with no person entering data.
- Intake. The input is rarely one file. It is a transaction's paperwork as a set: the signed purchase and sale agreement with its addenda, amendments and counteroffers, whether the PDF carries real text or only scanned page images.
- Reading the contract. From that set CSI identifies the terms of the deal, against a vocabulary built for this one kind of transaction: the price paid, the earnest money and who holds it, how the purchase is financed and for how much, the deadlines for inspection, financing, appraisal and closing, concessions from the seller, which party pays for which title policy, who the parties are, and how the property is identified down to its legal description.
- Keeping the receipt. No value travels without its origin. Each one carries the document and page it came from and the passage that supports it, so a reader can go from the number to the words behind it.
- Settling what governs. When a later amendment or counteroffer replaces an earlier term, the set is ordered by time and by authority, so every value the system tracks ends up as the one that actually controls.
- Doing the math. Those controlling terms go into a calculation layer that gives the same answer every time and is configured by jurisdiction. For Tennessee it computes the realty transfer tax, the mortgage indebtedness tax, recording fees, title insurance premiums from the rate schedules and the property tax proration, day by day, to the closing date.
- The statement. The output is a settlement statement for each side, buyer and seller. A line taken from the contract can be followed back to its passage; a line the system calculated can be followed back to the rule behind it.
- Answering questions. Questions are answered only from the documents that were sent in, each answer cites the passage it rests on, and when the contract says nothing on the point, the system declines to answer rather than guess.
Its methods, models and rules are proprietary.
Why he built it
When he opened his firm in 2002, the first time most buyers and sellers saw what their closing would cost was at the closing table, with a pen in their hand, even though the contract had held the answer since the day it was signed. He wanted his clients to know before they signed. What he ended up building is a way to read a contract back to the people who signed it as a settlement statement, their own terms turned into dollars, and it never closes: a contract sent at midnight on a Sunday is read the same as one sent at nine on a Tuesday. The story is the long version.
