Features

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.

Detection

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.

  • 54+ 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

Document Mode

Import any document, see results side by side

Drop in 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.

  • 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
De-identification

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.

Destructive

Replace

Numbered identifiers like <<PERSON1>> replace the original text. A legend page is appended for reference.

Destructive

Highlight

Semi-transparent overlays in entity-specific colors mark detected PII for review — non-destructive.

Non-destructive

Mask

Character-level replacement preserving text length. "Jane Doe" becomes "J*** D**" — readable shape, hidden content.

Destructive
Draw-to-Redact

Manual 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

Batch Processing

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.

Re-identification & Export

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.

.txt De-identified text
.xlsx Results table with entity type, confidence, method
.pdf Modified PDF with redactions applied
Privacy by Design
