danielle / harness·v2.0

The AI harness for the quietest part of regulated work.

Contracts. Disclosures. Controls. Charts. The Danielle Harness runs any document-heavy workflow against your playbook — and emits work your team can file, sign, or send.

01/the thesis

Every regulated industry runs the same workflow. We built one harness for it.

  • The rules are opaque — they live in playbooks, regs, and the heads of senior reviewers, not in the document being marked up.
  • The workflows are document-heavy. The artefact is prose, hundreds of pages of it, and the work is reading and reconciling line by line.
  • One missed clause or filing can reach seven figures downstream, and validation cycles consume weeks of senior time before anything goes out.
01 · OPAQUE RULES

The governing logic lives in playbooks, regulations, and the heads of the people who have done the work longest — not in the document.

02 · DOCUMENT-HEAVY

The work is hundreds of pages of prose that has to be read, marked, and reconciled line by line.

03 · COST OF ERROR

One missed clause, control, filing, or finding can compound into seven-figure exposure downstream.

04 · LONG VALIDATION

Review cycles stretch across weeks of senior review before anything goes out.

02/the harness

Six stages. Every output is traced, cited, and signed.

The Harness is one execution pipeline shared across every product. We didn't rebuild it for finance, controls, debt, or charts — we taught it a new playbook and shipped a new product.

03/the products

Four products. Built on the Harness.

Each is a named product with its own playbook, its own emit format, and its own buyer — but all four share the same Harness underneath. Every other workflow runs on the platform directly.See all products →See the platform →

04/the signature gesture

We render the work as a diff, not a chat.

Every change gets a gutter, a line number, and a marker. The output feels engineered, not annotated — you can audit it, accept it, or argue with it the same way you would code review.

05/engineered, not prompted

Four things a chatbot can’t promise.

The Harness isn’t a prompt. It’s an execution pipeline whose output you can hand to a regulator, an auditor, or opposing counsel.

FILE FIDELITY
The file you send is the file you get back.

A custom compiler writes changes into your original document — styles, tracked changes, macros, numbering, and redactions untouched. Only the spans we changed change.

NO FREE TEXT
The model can’t free-write.

Every output is a typed tool call resolved against your playbook. No tool call, no output — the model never narrates into the document.

INDEPENDENT VERIFIER
Nothing ships unverified.

A separate agent checks every output against the source. Unsupported claims route back instead of reaching you.

CITED + RE-RUNNABLE
Every claim cites its source.

Each output is grounded in a source span and signed against a playbook version. Re-run the matter against the same playbook — the audit trail is comparable and attributable.

06/grouped by buyer

Same harness. Different vocabulary.

LEGAL & FINANCE
Contracts, debt, private capital

High-volume review of contracts and finance documents — clauses, covenants, side letters, chains of title.

ENERGY
Oil & gas

Leases, royalties, title, JOAs — decades of technical documents read against the rule.

HEALTH
Records, claims, prior auth

Clinical records read against the rule. The vocabulary is charts, codes, criteria.

PLATFORM
Everything else

Compliance, controls, credit memos, discovery — no named product for your workflow? Bring your playbook and run directly on the Harness.
