gallsec: Three Ways to Prepare Sensitive Material for AI

Field notes

The site organizes privacy preparation into three separate paths rather than treating all sensitive material as the same problem. One path replaces data with labels and preserves reversibility through a key file; another permanently removes selected information, including from scanned PDFs while retaining page layout; a third swaps real prompt data for fictional values and describes restoring those values in the AI response. The homepage also says detection is optimized for Polish documents and shows that tools and dictionaries are still being prepared.
