Aperture E-Discovery  /  litigation  /  on-premise

Find where the record disagrees with itself.

Aperture reads an entire production and returns every contradiction and every fact — each tied to the exact words in the source. The one capability no major e-discovery platform ships, air-gapped on the firm's own hardware.

// what it does

One narrow job, done to evidentiary standard.

It extracts every factual claim, checks each against a verbatim quote that must literally exist in the source, then finds where those claims collide across the whole matter.
01
the difference

Cross-document contradiction detection

Seven types — factual, temporal, measurement, attribution and more — connected across the production, not ranked within one document. As far as we can find, no major platform ships this at all.

02
grounded

No hallucinated findings

Every claim must cite a verbatim quote that literally exists in the source, or it's dropped rather than shown. On the shipped build, 98.3% of emitted claims carry a citation that survives re-verification.

03
chronology

Who knew what, when

Position timelines show who asserted a claim first and how corroboration accumulated across the production — plus per-party consistency scorecards.

04
privilege

Privilege, flagged

A layered, promotion-only privilege screen flags attorney-client and work-product material; any layer can flag, nothing can silently unflag.

Air-gapped, local models. Verifiable by your own packet capture — disconnect and run the pilot.
We audit ourselves and publish what breaks. On our last internal audit, every headline number was recomputed from the artefacts on disk; three were withdrawn or restated. That audit ships with the pilot — we'd rather hand you our worst review than have your diligence team write it for us.

Questions, answered plainly.

What is Aperture E-Discovery?

Aperture reads an entire legal production and returns every contradiction and every fact, each tied to the exact words in the source — air-gapped on the firm's own hardware.

How is Aperture different from other e-discovery tools?

It connects contradictions across the whole production — not just ranking documents — and every finding must cite a verbatim quote that literally exists in the source, or it's dropped rather than shown.

Does Aperture run in the cloud?

No — it runs on-premise, air-gapped. You can verify with your own packet capture that nothing leaves the box.

How is it priced?
