Plumb Analysis

Keep your analysis true.

Trust the analysis without doing the analysis twice.

Plumb Analysis shows you exactly what AI changed, left out or added while turning your information into analysis.

Reviewing with Plumb

Review the part that changed. Not the entire analysis.

The analysis stays where it is. Findings sit against it. Open one and you get the statement AI wrote, the information underneath it, and what changed between them.

Why a supported claim can still get the source wrong

Plumb Analysis reviewing a generated support wrap-up. The brief sits on the left with its marked statements; the movements panel on the right has one finding open, showing the source clause, the output sentence and what changed between them. — The analysis stays. The findings sit on it. You open the one that moved.

Multi-source

Many sources. One analysis. More ways for the answer to go wrong.

Email. Calls. Research. Spreadsheets. CRM records. Policy. Output from an earlier AI step. One piece of analysis can draw on all of it at once.

Plumb follows the claim back across all of it.

Problems that only show up when the answer was built from more than one source.

Nothing supports the claim

The conclusion appears in the analysis, but none of the sources actually say it.

The sources disagree

The analysis quietly chooses one version and presents it as settled.

A qualifier disappeared

It came from one source, and did not survive being combined with another.

The right fact, the wrong source

The fact is accurate. It is attributed to material that never said it.

Something relevant never used

It was available in the set, and never made it into the conclusion.

An earlier summary carried forward

An earlier AI summary changed something, and the final analysis inherited it.

Why multi-source analysis fails even when every source is correct

What Plumb can see

Know exactly what went wrong.

A dropped condition is not the same problem as a changed number. A weakened requirement is not the same problem as a widened claim. A reviewer needs to know which one they are looking at before they can decide anything.

Condition removed Condition added Exception omitted Scope widened Scope narrowed Possibility became certainty Certainty reduced Requirement weakened Requirement strengthened Permission expanded Prohibition removed Number changed Timing moved earlier Timing moved later Duration changed Attribution changed Commitment introduced Relevant information omitted Unsupported claim added Meaning held

If Plumb knows what happened, it tells you what happened. Not just changed.

What Plumb Analysis gives you.

Verification

Check the analysis against the information it was built from.

You see which parts held and which parts need attention.

Speed

Review what changed instead of rereading the sources and rewriting the brief.

Traceability

Follow a finding back to the source material, including across multiple sources and an earlier AI step.

You see what the source said and why the finding was raised.

Audit trail

A record of what AI produced, what it was based on, what Plumb found, and what was reviewed.

If someone asks later how an AI-assisted analysis reached a result, that record is the answer.

Scale

Run AI on more analysis work without growing manual review at the same rate.
