Piixie documentation
Anonymize documents on your own machine. A local language model finds the PII, Piixie rewrites the file, and the original never leaves your computer.
What is Piixie?
Section titled “What is Piixie?”Piixie is a desktop app for macOS, Windows, and Linux that removes personally identifiable information from documents before you share them. Drop in a PDF, Word file, Markdown or plain text document, pick an anonymization mode, and Piixie writes a safe copy next to the original. Detection runs on a local Gemma model through llama.cpp, so the raw document stays on your machine unless you explicitly configure a remote endpoint.
