data-redaction

An open-source framework for detecting, redacting, masking, and anonymizing sensitive data (PII) across text, images, and structured data. Supports NLP, pattern matching, and customizable pipelines.

Filter sensitive information from free text before sending it to external services or APIs, such as chatbots and LLMs.

LLM privacy gateway in Go — millisecond-latency PII and secret redaction. Used in production by PackyCode.

Find and redact sensitive data before it leaks — a fast, offline CLI and Go library that detects PII, secrets, and credentials in files and streams, scores them with context-aware confidence, and redacts them format-preserving. Nothing leaves your host.

Python CLI tool to redact and un-redact sensitive data from text files. 🔐📝

Rust derive macro for redacting sensitive data in std::fmt::Debug

Automatically filter sensitive information from RubyLLM conversations using Top Secret.

Browser-based redaction utility that lets you paste any payload—HTTP exchanges, JSON, YAML, CSV, configs—and instantly strip out sensitive values while preserving structure.

Redactify is an efficient data redaction tool that secures sensitive text using advanced NLP and rule-based methods. It combines transformer-based NER, regex, and Presidio analysis to detect and mask personal information through full redaction or partial masking—ensuring compliance while preserving data utility.

Open-source data protection framework for AI agent workflows in n8n. Detects, tokenizes, and reversibly anonymizes sensitive data before it reaches your models.

Privacy-first Windows app that finds sensitive data before files are shared. Scans locally, supports optional on-device Ollama AI, and creates redacted copies without uploading source files.

Privacy and log encryption. Enterprise-grade encrypted log processing system with Zero Trust architecture. AES-256-GCM encryption, PII redaction, tamper-evident audit trails. Python/FastAPI/Kubernetes. GDPR/HIPAA compliant.

Safe-Paste is a developer-focused tool that ensures you never leak sensitive information when sharing code. It scans your pasted content for secrets, tokens, credentials, and confidential values, then redacts or replaces them with safe placeholders. Ideal for AI prompts, documentation, issue reports, and public chats.
