Extract data from promissory notes

A promissory note is the shortest document that still carries a legally binding promise to pay, and under UCC Article 3 it is a negotiable instrument, which means it can be transferred and enforced by whoever holds it. A lending operations team, a treasury analyst, and a paralegal all pull the same fields from one: the maker who promises to pay, the payee entitled to receive, the principal amount, the interest rate and how it accrues, the maturity date, and the signature that executes it. A private lender or a company managing intercompany loans might hold a stack of notes ranging from a $25,000 personal loan at 6% simple interest due in a lump sum to a $500,000 note amortizing over 48 monthly installments, each dated, each naming a different maker and payee, and some secured by collateral described in the note itself. What makes a note more than a form is the interaction of principal, interest, and the payment schedule. A note stating a $500,000 principal at 7.5% annual interest amortizing monthly implies a schedule where each installment splits into principal and interest, and the total due at maturity depends on the accrual method, simple or compound. A demand note has no fixed maturity and falls due when the payee calls it. Collateral, a governing-law clause, and a witness or notary block change how the note is enforced. Payment instructions may point to an IBAN, an ACH instruction, or an account for wire transfer rather than a physical location. Talonic reads the promissory note and returns the maker and payee with their addresses, the principal, interest rate and type, maturity date, and any installment schedule as structured rows, keeping the governing-law and collateral clauses as text. A note dated 2026-04-01 for a $500,000 principal at 7.5% maturing 2030-04-01 in USD loads into the loan system with its payment schedule, so a lending team books it from structured data rather than a re-keyed page.

What gets extracted from promissory notes

How extraction works for promissory notes

Promissory notes arrive as executed PDFs, notarized scans read with OCR, and templates filled in a document platform, and because there is no single standard form, the same terms sit in different places on every note. Talonic classifies the note and maps it to the instrument schema in the Field Registry, which captures the parties, the money terms, and the schedule without a per-template layout. The maker and payee are tagged by role with their addresses and any tax identifiers, and the principal, interest rate, interest type, and maturity date surface as discrete fields. Where the note carries an installment schedule, each row is returned with its due date, principal, interest, and total, and where it is a demand note the maturity is marked accordingly. Governing-law, collateral, and witness or notary clauses are kept as text so a paralegal reads the source rather than a paraphrase. Every value returns with a confidence score and pixel-region provenance under DIN SPEC 91491 conformity, so a lending team can verify a $500,000 principal and its rate against the executed note before booking it.
