Local File Secret Redactor

Let Agents read local files while redacting API keys, passwords, and secrets

Problem

Developers often let AI Agents read local files (.env, config) but worry about secrets leaking into the LLM context. Manually cleaning files is tedious and error-prone, while blocking Agent access hurts productivity.

Solution

A local proxy or CLI that detects and replaces sensitive values (API keys, passwords, tokens) with placeholders before file content reaches the LLM, then restores real values in the LLM's response. Supports custom regex and common secret formats.

Users

Developers using coding Agents like Claude Code and Codex, and teams that need AI to process sensitive data.

MVP

Intercept file reads and scan for secret patterns; replace secrets with placeholders; restore placeholders in LLM responses; include built-in patterns for AWS, OpenAI, GitHub, etc.; support custom regex rules.

Revenue

Open-source core with paid team edition (central policy, audit logs); or a one-time desktop purchase at $19.

Why now

AI coding Agents are widespread and developers feed them more local files, raising secret leakage risks; indie developers can address this security gap with a lightweight local tool, no massive cloud needed.
