BALMAS AI anonymizes PDF, Word, Excel, PowerPoint, TXT and CSV files locally in your browser before you use them with ChatGPT, Claude, Gemini or Copilot. It detects names, IDs, phones, companies, amounts and secrets such as API keys, lets you keep, replace or remove each finding, and returns a clean copy in the original format with metadata stripped. Three cleaning levels; on PRO, Round-Trip Restore puts real values back into the AI output. balmas-mcp is a local, read-only MCP server that anonymizes every file an agent reads.
