Billable trust

Show clients your AI work got measurably better.

Before-and-after proof reports with scores, evidence, and version hashes you can hand to a stakeholder. Make "we improved it" a document, not a claim.

The deliverable

Reproducible evidence, not a claim.

A proof report is the artifact you hand over: score delta by dimension, the evidence behind each mark, and a version hash anyone can re-run. It sells reproducible evidence — never a certification. Sample shown below.

Evidence: v1 left “good” undefined; v2 adds an output contract and a stop rule. The eval case that v1 failed now passes.

What is in the report

A document, not a claim.

A proof report is the artifact you hand a stakeholder. It stands on its own and survives scrutiny because anyone can re-run it — the value is reproducible evidence, never a badge of authority.

Score delta by dimension

Before and after on each rubric dimension, so "better" is specific rather than a single headline number.

Evidence behind every mark

The finding that drove each score and the eval case that demonstrates the behaviour change.

A version hash

The exact artifact is identifiable, so the report points at something reproducible, not a moving target.

Re-runnable, not certified

We sell reproducible evidence — a client can run the same check and get the same result. We deliberately do not call it "certified."
