Open source
A redaction tool asks you to trust it with the documents you are least willing to leak. That trust should be checkable, so the code that reads a file and decides what to remove is public.
What that gets you
Not open source as a virtue, but as something you can act on.
Read how detection works
The recognizers, the scoring, and the rules that decide what counts as sensitive are all in the open. You can read them before trusting them with a document.
Run it yourself
The same engine we run is the one you can deploy, so documents never have to leave your infrastructure.
Verify a redaction
Same input, same policy, same output. Deterministic results you can reproduce and audit rather than take on faith.
Fork it
Add a recognizer for a format we have never seen, or change how a conflict resolves. Nothing about the pipeline is sealed.
No licence surprises
Apache 2.0 for the engine, MIT for the clients, AGPL for Studio. Every repository states its terms in full.
Built in the open
Issues, commits, and releases are public. The history of how a detection rule got its current shape is there to read.
The repositories
The detection framework, the pipeline it runs in, and the server around it, with the licence each one carries.
nvisycom/server
Self-hosted backend with REST and WebSocket APIs for document processing, integrations, and data management.
nvisycom/studio
Web and desktop app for detecting and redacting PII in documents, processed locally in the browser or a native client.
nvisycom/docs
Setup and self-hosting guides, SDK usage, redaction-policy reference, and a full OpenAPI spec.
nvisycom/mcp
Model Context Protocol server exposing the platform to Claude Code, Claude Desktop, and other agent runtimes.
nvisycom/elide
Composable redaction framework for building PII detection and removal pipelines over unstructured data.
nvisycom/elide-runtime
Stateless document pipeline: wire schemas, policy-driven redaction governance, and the engine that ties them together.
Run it on your own infrastructure
Deploy the engine yourself, with air-gapped support and no document leaving your environment.
