anonymize.today — Simple, Transparent PII Detection & Anonymization

Deterministic, regex-based safety for GDPR audit fit. No AI, no guessing—just transparent, audit-fit results on ISO 27001-matched servers in Germany.

SaaS Platform PII Finding PII strip GDPR ISO 27001 Microsoft Presidio

Platform Overview

anonymize.today is a simple, transparent PII (Personally Identifiable Info) finding and PII strip platform built on Microsoft Presidio technology. The platform uses predefined regex patterns — deterministic output, reproducible for the same input on the same ruleset version. Fully audit-fit for rule-set audit fit.

PII Detection & Anonymization Methods

PII Detection

Detect 256 item types across private IDs, financial data, government IDs (30+ global variations), location info, digital IDs (IP, MAC, URLs), team data, and temporal data.

Item count grows as new patterns ship; now list defined in the live items table.

5 Anonymization Methods

  • Replace — Substitute with placeholder.
  • Redact — Remove fully.
  • Hash — SHA-256 hashing.
  • Encrypt — AES-256-GCM encoding.
  • Mask — Partial masking.

Multi-Language Support

27 languages including English, German, Spanish, French, Italian, Japanese, Chinese, Korean. RTL support for Arabic. Auto language finding.

Detection Presets

Default and public presets for common audit fit scenarios. 89 built-in presets optimized for local PII patterns. Real-time processing without data storage.

Why Regex, Not AI?

Deterministic Approach

The platform deliberately uses regex-based finding rather of AI/ML for critical audit fit perks.

Regex-Based Approach

  • Deterministic, reproducible results (same input + same ruleset version)
  • Fully audit-fit for audit fit.
  • No training data needed.
  • Transparent decision making.
  • Fast, predictable speed.
  • No model drift over time.

AI/ML Approaches (Avoided)

  • Results vary between runs.
  • Black box decision making.
  • Needs training data.
  • Difficult to audit.
  • Higher compute costs.
  • Model drift over time.

How It Works

The 10-Step Process

  1. Input Text — Submit your document via web interface, API, Word Add-in, or Chrome Extension.
  2. Language Finding — System identifies the document language for optimal processing.
  3. Tokens — Text is broken into tokens for pattern matching.
  4. Pattern Matching — Regex patterns scan for 256 item types.
  5. Context Study — Surrounding text improves finding accuracy.
  6. Confidence Scoring — Each finding gets a confidence score.
  7. Item Labeling — Found items are categorized by type.
  8. Review Results — See all detections with positions and scores.
  9. Apply PII strip — Choose your method: Replace, Redact, Hash, Encrypt, or Mask.
  10. Output Document — Download your anonymized document.

Fit & Limitations

Best fit and known limitations

Best for

Quick, transparent, deterministic PII scrubbing with no signup overhead — pilots, light use, and education or research teams running short experiments before scaling.

Not the right fit

Image redaction with OCR (use cloak.biz); firm-wide audit logging or MCP link-up (use anonym.legal); workloads that need broad multilingual coverage beyond Latin scripts.

Known limitations

Regex-only finding misses ambiguous names without ML support; coverage is 27 languages versus 48 on the firm-wide platforms; the free tier resets every 30 days.
