Reva

Local-first document intelligence for reinsurance operations.

Ingest messy submissions, extract source-cited data, reconcile control totals, review exceptions, and export clean records from one analyst workspace.

What Reva does

Reva is built for the document flow between cedents, brokers, and reinsurers. Those teams receive spreadsheets, PDFs, scanned images, emails, bordereaux, statements, slips, loss runs, and claim notices. Reva turns that inbound noise into reviewable data with evidence attached.

In plain English:

1. Drop in the files. Reva accepts common office, email, image, spreadsheet, text, and PDF formats.
2. It reads and classifies them. Digital documents are parsed directly; scanned documents use local OCR.
3. It extracts the important fields. Cedent, broker, reinsurer, period, currency, premium, claims, commission, cession percentage, retention, limit, and contract references are normalized.
4. It proves where values came from. Every value carries provenance, and geometry-backed citations can point back to the source area.
5. It checks the money. Control totals are compared against line-item totals under a configurable tolerance.
6. It lets an analyst decide. Exceptions, confidence, citations, and suggested corrections are reviewed before export.
7. It exports clean records. Data can leave as CSV, Excel, or JSON using reusable templates.

The important product decision: the default workflow is deterministic and keyless. AI providers can assist when configured, but upload, extraction, reconciliation, review, and export do not depend on a hosted model.

Capabilities at a glance

Capability	What it means for a non-programmer	Why it matters
Any-format intake	Reva can accept the file types a real operations inbox receives.	Less manual file cleanup before review.
Local OCR	Scans and photographed tables can still become searchable text.	Paper and image submissions do not become dead ends.
Source-cited fields	Values can point back to the original document text or region.	Reviewers can trust but verify quickly.
Reconciliation	Stated totals are checked against computed line-item totals.	Financial breaks are visible before data leaves the system.
Learned mappings	Sender-specific column names can be remembered after correction.	The second file from the same sender is faster than the first.
Knowledge Hub	Product and domain notes are searchable inside the analyst workspace.	The assistant can answer with project context instead of guessing.
Export templates	Data leaves in the shape the market or downstream team expects.	Review work turns into usable operational output.

How the system fits together

Layer	Responsibility
web/	The analyst application: workspace, review, export, mappings, settings, Knowledge Hub, and assistant.
src/Reva.Web/	The ASP.NET Core host: HTTP API, streaming endpoints, agent endpoint, and production static-file serving.
src/Reva.Core/	The shared reinsurance vocabulary: document states, canonical fields, contracts, and value formatting.
src/Reva.Infrastructure/	The document machinery: storage, parsing, OCR, extraction, mapping, reconciliation, export, settings, and agent tools.
contracts/	Stable JSON schemas for review payloads and citation geometry.
docs/	Product, architecture, demo, packaging, interview, and learning documentation.

The runtime path is simple: analyst browser → Next.js app → ASP.NET Core API → deterministic workflow → SQLite storage → review/export. Optional model providers attach through settings and never replace the deterministic source of truth.

Quick start

1. Run the API

dotnet run --project src/Reva.Web/Reva.Web.csproj -- --no-open

2. Run the web app

cd web
$env:NEXT_PUBLIC_API_BASE_URL = "http://localhost:5158"
pnpm install
pnpm dev

Open http://localhost:3000.

3. Try the demo flow

1. Open Workspace and load demo scenarios or upload a document.
2. Open Review and inspect fields, citations, confidence, and exceptions.
3. Ask Assistant which documents need review or where a value came from.
4. Open Mappings to see sender-specific header normalization.
5. Open Export and download CSV or JSON.
6. Open Showcase for the guided product tour.

Production packaging

Reva packages as a single ASP.NET Core host that can serve both the API and the exported frontend. The Windows packaging script builds the static web app, copies it into the API host, publishes Reva.exe, and smoke-tests the package against real HTTP routes.

See docs/packaging.md for the exact shape.
