Read & ask
Original PDFs alongside grounded answers, exact evidence passages and page-specific source navigation.
Document intelligence · Portfolio showcase
Evidence,
before answers.
Read the original. Follow the citation. Understand what the evidence supports—and where it stops.
Static demonstration
This page uses synthetic examples and recorded screenshots. Sign-in, uploads, AI questions and exports are not interactive here. No documents are collected and no model requests are made.
A traceable document workflow
Built for careful review.
Capabilities implemented in the repository. A verified private deployment is required to use them with your own documents.
Connect the context
Collections and questions across selected documents, with workspace and source-version checks.
Compare with limits
Structured amounts, dates and supported obligations. Uncertainty and insufficient evidence remain visible.
Keep the review
Reviewed comparison snapshots, stale-source warnings and JSON/PDF exports that make no model calls.
Recorded on stable main
The original stays in view.
A real browser capture of the Evidence Viewer using a synthetic PDF and intercepted test answers. This screenshot does not demonstrate a live hosted backend.
Illustrative synthetic evidence
Useful differences. Honest boundaries.
Document A · example passage
“Payment USD 100 due December 1, 2026.”
Document B · example passage
“Payment USD 200 due December 1, 2026.”
Explicit amount difference
The stated amounts differ. This alone does not establish a contractual contradiction or whole-document equivalence.
Static, hand-authored illustration of the supported comparison scope. No AI endpoint is simulated.
Semantic comparison uses bounded rule-based normalization. It does not provide unrestricted AI semantic understanding, full-document completeness, or cryptographic verification of historical originals.
Design preview · separate draft PR #13
Graphite Precision.
The enterprise interface is a separately reviewed design branch. It has not been merged into the stable main shown above.
Deployment status
Public processing is closed.
Managed authentication, provider budgets, storage recovery and operating safeguards must pass deployment-specific checks before a private beta can open.
