What is PII detection and why does it matter?

PII detection finds personally identifiable information (names, emails, IDs, location data) in your datasets. Masking it properly is required by GDPR, CCPA, and other privacy laws.

Is Amaze GDPR / RODO compliant?

Yes. Our masking rules are mapped to GDPR Article 6 and pseudonymization best practices. We also help you generate audit reports for your DPO.

Does my data ever leave my machine?

No. Every tier runs locally on your own machine. Enterprise adds a self-hosted team deployment and a local API, so your data never leaves your environment.

What data sources do you support?

Files (CSV, JSON, PDF, DOCX, XLSX) processed locally on your machine. Self-hosted enterprise builds can also connect to your own databases.

How long do you store anonymized data?

Amaze runs on your device and does not send your data anywhere, so there is nothing for us to store. You stay in full control of your files.

What support do Enterprise plans include?

Enterprise plans include priority support and onboarding, plus help rolling out Amaze across your team.

Does Amaze work without internet access?

Yes. Amaze runs fully offline — you can disconnect from the network entirely (air-gap) and anonymization still works. No outbound connections happen while a document is processed.

Anonymize before you paste into AI

Keep sensitive data on your machine, not in the model

Amaze detects and masks PII (Personally Identifiable Information) entirely on your own machine or infrastructure. So lawyers, doctors, and analysts can use ChatGPT, Claude, and Gemini without sending client data to the cloud.

The problem

Sharing sensitive documents shouldn't mean risking a leak

Modern AI tools are too useful to ignore — and too risky to feed unredacted client data. Amaze closes the gap.

GDPR fines up to €20M

A single leaked document can trigger regulator-level penalties — and they target controllers, not employees.

Cloud AI is a black box

Pasting client data into ChatGPT or Claude sends it to servers you don't control. Once it's out, it's out.

Manual redaction breaks

Find-and-replace leaks data in metadata, comments and headers. Humans miss things. Always.

Everything you need to stay compliant

From discovery to masking, Amaze covers the full PII lifecycle on your device.

Runs on your infrastructure

On-device: your data never leaves your machine.

One-click PII detection

Automatically spot names, emails, phone numbers, IDs, and Polish identifiers (PESEL, NIP, REGON, KRS) across any document.

Built for Polish data

Detects PESEL, NIP, REGON and KRS, and recognizes Polish names across grammatical cases.

OCR for scanned documents

Scanned PDF pages go through local OCR — text from scans is detected and masked just like in a regular document, fully offline.

Operation history & reports

Every anonymization operation is recorded in local history. Export summaries and details to CSV/JSON with one click.

GDPR / RODO compliant

Built-in masking rules aligned with GDPR, CCPA, LGPD, and HIPAA-ready workflows.

Two-way workflow

Anonymize, work in any AI tool, then restore originals locally with your private mapping file.

Air-gap ready

Disconnect from the network entirely — anonymization still works. No outbound connections happen while a document is processed.

Detected data types

13 categories. Calibrated for GDPR

Out-of-the-box coverage for the entities that matter in legal and compliance work.

How it works

From raw data to safe-to-share datasets in four simple steps, all on your machine.

Open your file

Drop in a document or connect a local database. Nothing is uploaded anywhere.

Scan for PII

Amaze scans columns, payloads, and documents on your machine to find sensitive data patterns.

Mask & use

Apply your rules once, then paste anonymized data safely into any AI tool.

Restore with your key

Bring the original values back locally with your private mapping key — anonymization is fully reversible.
