Nvisy Server

Detect and redact sensitive data across documents, images, and audio.

The open-source multimodal redaction API: an LLM-powered engine and HTTP service that finds PII and applies your redaction policies, wrapped in a multi-tenant, self-hostable Rust server.

nvisy.com · docs.nvisy.com · app.nvisy.com

A document flows through two phases: detection analyzes it for sensitive entities and stores a reviewable report; redaction applies the pipeline's policies (with optional reviewer edits) to produce a redacted file. Detection runs asynchronously off a transactional work queue; redaction is synchronous and repeatable. Everything is scoped to isolated workspaces with per-workspace credential encryption.

Warning

Active development. API not stable. Public APIs, configuration shapes, on-disk formats, and wire protocols may change without notice between releases. Pin a specific commit if you depend on this in production.

Features

• Multimodal redaction: detect and remove sensitive data across PDFs, office documents, images, and audio.
• AI-powered detection: LLM- and pattern-driven PII/entity recognition, governed by configurable redaction policies.
• Reviewer edits: suppress a false positive, retag a detection, or add one the analysis missed, then re-redact, as many times as needed.
• Workspace isolation: multi-tenant workspaces with HKDF-derived, per-workspace credential encryption.
• Live status: server-sent event streams for detection progress and notifications, fed by NATS pub/sub.
• Interactive docs: auto-generated OpenAPI served through a Scalar UI.

Requirements

• Rust + Cargo: 1.99+, Edition 2024
• PostgreSQL 18+, NATS 2.10+ (JetStream), and an S3-compatible blob store (RustFS by default). The dev compose file provides all three.

Quick start

The fastest way to get started is with Nvisy Cloud. To run a server locally:

make install-all       # Install tools and make scripts executable
make generate-all      # Generate .env, auth keys, and apply migrations

docker compose -f docker/docker-compose.dev.yml up -d   # Start Postgres, NATS, RustFS
make run                                                # Run the server

The API then serves interactive OpenAPI docs (Scalar UI) at the running server's docs path. For self-hosted deployments, see docker/ for compose files and infrastructure requirements, and .env.example for configuration.

Run make help to list the available commands.
