Redact-a-bit strips identifying PII from PDFs and text files and swaps it for realistic fake data, partial masks, or [REDACTED] tags — so a document stays usable (e.g. to paste into AI) without exposing who it's about. Everything runs locally on your machine.
Install (Windows)
- MSI:
Redact-a-bit_0.2.0_x64_en-US.msi— or installer:Redact-a-bit_0.2.0_x64-setup.exe. - This build is unsigned, so Windows SmartScreen shows "Windows protected your PC" → click More info → Run anyway. It's a free, open-source tool and the source is right here to verify.
Privacy
- Nothing about your document leaves your machine. Optional local detection models (GLiNER) download once from Hugging Face on first use (inbound only); after that it runs with Wi-Fi off.
In this build
- Three levels × three modes (Fake / Mask / Label), regex floor + optional GLiNER name/address detection, true PDF-as-PDF redaction.
- Inputs: PDF and plain text (
.txt,.md). - Theme toggle (System/Light/Dark), keyboard-navigable UI, graceful handling of unsupported files, filenames encode level + mode.
AGPL-3.0-or-later. macOS/Linux builds to come.
