Stop redacting documents by hand. Let AI do the heavy lifting.
PII Anomalyzer uses dual AI models to detect PII, paired with a manual draw-to-redact toolbar — so you catch everything, miss nothing, and never upload a file to do it.
Context-aware AI, not just regex
PII Anomalyzer runs two independent AI models on every scan and combines their results. The dual-model approach catches what single-model tools miss: "Jordan" is recognized as a person in one sentence and a country in the next.
- Wide range of entity types detected automatically
- Dual-model detection for higher accuracy
- Pattern recognizers for US, UK, AU, and NZ postal formats
- Surface form propagation — detect once, match everywhere
- Form field PII detection for fillable PDFs

Import any document, see results side by side
Import a PDF, Word document, or Excel spreadsheet. PII Anomalyzer auto-detects the document type — native text, fillable form, or scanned image — and applies the right processing pipeline. A side-by-side viewer shows the original next to the de-identified version with native vector PDF rendering. New to this? Follow the step-by-step guide to redacting a PDF.
- Auto-detects PDF type: native, form, or scanned
- Non-PDF formats converted automatically
- Side-by-side original vs. de-identified view
- Coordinate-aware text processing
- Built-in OCR for scanned documents
Four ways to protect sensitive data
Choose the right method for your workflow — from permanent removal to non-destructive annotation.
Redact
Black boxes permanently cover PII. The underlying text is removed from the PDF layer — gone for good.
DestructiveReplace
Numbered identifiers like <<PERSON1>> replace the original text. A legend page is appended for reference.
DestructiveHighlight
Semi-transparent overlays in entity-specific colors mark detected PII for review — non-destructive.
Non-destructiveMask
Character-level replacement that preserves text length while hiding the value.
DestructiveManual precision for what AI misses
Handwritten text, logos, signatures, and visual PII in images — some content needs a human eye. Draw redaction rectangles directly on the PDF, resize with drag handles, and nudge with arrow keys for pixel-perfect placement.
- Select, Draw, Delete, and Clear All toolbar modes
- Click-and-drag to create redaction boxes on any page
- Resize by dragging edges, nudge with arrow keys
- Always renders as solid black — explicit "remove this" intent
- Persists between de-identification runs for iterative refinement
- Zoom-independent — coordinates stored in PDF points

Process multiple documents at once
Queue multiple documents for processing in a single workflow. Each document gets its own de-identified output, modified PDF, and results table — combined into a single exportable dataset.
De-identify, share safely, translate back
Export a de-identified document using the Replace method, share it with AI tools or external reviewers, then use re-identification mode to translate their responses back to the original context. You can also use it to verify redactions before final release. Export de-identified text, results tables (XLSX), and modified PDFs.
100% offline PII detection, redaction, and anonymization.
Every AI model, every algorithm, every computation runs on your machine. No document data leaves your computer. No telemetry, no analytics, no usage data sent back to us. There is no server holding your documents because there is no server.
