US closing documents for lenders, businesses, and founders

Every document your deal needs to close.

Built from your terms and the letter of the law. No model drafts a word of it.

OpenShut returns every document a US transaction requires, assembled into one signature-ready binder from your terms and the law that governs them. The figures are computed from the terms you enter, and every clause is the operative text of the statute or standard form it comes from, reproduced word for word for your counsel to verify against the source. Because no language model drafts any of it, there is no step where a figure or a clause could be invented, and the assurance you are relying on is the law itself.

Accuracy

Every number and every clause traces to its source.

Each figure is calculated in code from the terms you enter and the rules of your program, then reconciled against the source it came from before any document assembles. Statutory clauses are reproduced verbatim from the authority they cite, and every other clause comes from a frozen, source-verified library, so any provision in the binder reads straight back to its source. Nothing is drafted on an estimate, and nothing reaches you before it is checked against the program rules built into the engine.

Why this is different

Every legal-document tool today makes you choose between wrong and slow.

A template hands you a blank form and gives the law back to you. An AI drafts something that reads right — and is sometimes wrong, with no way to tell which clause. OpenShut is neither. The operative text of every document is fixed to its source — the statute, the regulation, the standard form. The figures are computed from your terms and checked against the legal limit before anything generates. What you get is not a draft to review. It is the document — the way a top firm would produce it — in minutes, for a fraction of what a closing costs in counsel time.

From term sheet to closing table

Four steps from your terms to a signature-ready binder. You confirm every computed figure before drafting begins, so the documents match the transaction precisely.

  1. 01

    Enter the deal

    Pick the program and enter the terms — parties, amounts, dates. Your firm's details fill in from your organization profile, so you only type what is specific to this deal.

  2. 02

    Confirm the figures

    Every computed figure — rate ceilings, fees, schedules — is shown beside the rule it was derived from. Confirm or correct each one; nothing generates until you do.

  3. 03

    Generate the binder

    Every document the transaction requires assembles as one set, checked against the federal and state rules for your program, and ordered for the closing table.

  4. 04

    Download and close

    Export signature-ready documents as Word files. Counsel review is recommended before execution. An append-only audit log records actions on the deal, and each generated document retains the record of the program checks behind it.

The platform around the binder

Generation sits at the center. Verification, compliance, the audit trail, the data room, and the API run around it.

Security

Built to hold a bank’s most sensitive files

Your deal data is handled with the discipline a lending institution applies to its own records. Every file is sealed inside your organization and reachable only by the people you authorize, every action taken on it is recorded permanently, and the platform is held to the same controls your auditors will ask about. Your security team is welcome to review all of it.

Sealed to your firm

Each organization's data is isolated end to end. No other client, and no one outside the team you authorize, can reach it.

A permanent, tamper-evident record

Actions on your deals and documents are written to an append-only record that can be reviewed but never quietly changed.

Held to bank-grade controls

We maintain the safeguards your auditors expect and are preparing for SOC 2. We will walk your team through each control on request.
