Sourcetrace · document intelligence by Lumen & Lever · part of The Build

Your contracts are full of clocks. They run whether or not anyone is watching.

Controlled document intelligence over your organisation’s documents, spreadsheets and operational records. Every answer traces to source.

Private Australian hosting is available. Where it is selected, your data stays in Australia.

Exhibit
Question

When does the option to renew have to be exercised?

Sourcetrace

Written notice must be given no earlier than twelve and no later than six months before the term ends. The term ends 30 June 2027, so the window runs 30 June 2026 to 30 December 2026.

123 Collins Street, Lease.pdf

page 14 · clause 12.2(a)

"The Tenant may renew the Lease by giving the Landlord written notice not less than six (6) months and not more than twelve (12) months before the expiry of the Term."

Specimen. A lease question answered to page and clause. The answer is checkable because the source came with it.
The gap

An answer you cannot check is an answer you cannot rely on.

General assistants read across your files and return an answer. As a rule they do not show which line produced it.

Tools built for drafting and summarising are fine for drafting and summarising. For a decision that carries liability, the source is the point.

Sourcetrace answers, then shows the clause.

What Sourcetrace does

Three things, and it shows its work on every one.

Reads your material.

Contracts, leases, reports, spreadsheets, correspondence, operational records.

Answers in plain language.

Ask a question, get an answer a board can read.

Traces every answer to source, and watches the deadlines.

Document, page, clause. Nothing asserted without a line behind it, and every dated obligation surfaced before it passes.

Sourcetrace includes the document-structure engine Lumen & Lever uses before model work begins. It preserves layout, tables, annotations and page evidence before anything reaches a model. The controls are set out in the standard.

Technical provenance

The lineage is public.

The structure-preserving approach behind Sourcetrace started as rtfstruct, an open-source parser that reads Rich Text Format as a structured document tree rather than as plain text. That public lineage matters because traceability starts before a model sees the material.

rtfstruct is published under Apache-2.0. Inspect the source repository, cite the archived v0.1.1 release using DOI 10.5281/zenodo.21781834, and read why we built rtfstruct.

Where it applies

The same capability, pointed at the records that carry the risk.

Property

Lease portfolio intelligence

Every lease read and reconciled to source: option windows, rent reviews, make-good and outgoings, each answer tied to its clause.

The property application

Construction

Contract administration

Every entitlement and claim traced to the clause behind it, with the chronology assembled from the site record.

Document-intensive workflows

Any organisation whose decisions live in contracts, reports, spreadsheets and records. If the work is document-heavy, it is in scope.

How we engage
1

The Board Session

A$5,000, all in.

Your board sends its questions ahead. Every one comes back answered in writing. Then ninety minutes in the room, and you leave with decisions, not a presentation.

One week, end to end.

The Proof

A$9,500, fixed.

Pick the one job you need technology to do. An AI workflow. A contract read. A report produced. A slow cycle shortened. We run it on your own material for two weeks. It works, or you get a written account of why it does not.

The Build

From A$35,000, quoted after a Proof.

We build the system, fit the controls, and run it. One proposal, one number, and the running of it is in the number.

Talk about a Build

All prices are in Australian dollars. There is no retainer: you fund one proven piece of working functionality at a time, and each release of funds follows a demonstration rather than a promise.
