Why Piixie

The AI anonymizer that never uploads your data.

You use LLMs to get work done. You should not have to paste raw PII into someone else's service. Piixie strips private data on your machine so you send only what you intend.

LLM-Powered Detection

Context-aware AI finds PII that regex and rules miss. Names, relationships, embedded references that span across pages and tables.

Any File Type

PDFs, DOCX, spreadsheets, images, databases, plain text, JSON, XML, emails. One tool handles them all with the same intelligent pipeline.

Your Machine, Your Data

Everything runs locally. No cloud uploads, no API calls to external services unless you choose. Deploy standalone, on-premise, or with your own LLM.

Anonymization Modes

Three ways to protect sensitive data.

Choose the right mode for your workflow. Some need the strongest redaction. Others need the document to stay readable for demos, tests, or prompts.

Redact

Replace names, emails, phone numbers, and other PII with solid blocks. The strongest mode for zero-leakage compliance.

Explore redaction

Replace

Swap in stable placeholder tokens like [PERSON_1] and [EMAIL_1]. Perfect for review, tracing, and audit trails.

Synthesize

Generate realistic fake values locally using Faker-backed profiles. Documents stay readable for demos, tests, and LLM prompts.

Data Sources

Every file type your team touches.

One pipeline handles text, structured data, images, and documents. Vision-capable LLM means no separate OCR step needed.

DOCX

XLSX

CSV

TXT

Markdown

JSON

XML

HTML

Images

Databases

And more formats on the roadmap. Piixie aims to support every file type that contains PII.

How It Works

Intelligent pipeline, local execution.

The same pipeline runs on the desktop, at the command line, and on a shared server. Every step happens on your machine.

Testimonials

Teams trust Piixie with their most sensitive data.

"We evaluated every anonymization tool on the market. Piixie was the only one that kept patient data entirely on our HIPAA-compliant servers. No cloud risk, no compliance headaches."

Dr. Sarah Reeves

Chief Privacy Officer, MedSecure Health

"Piixie cut our data prep time by 80%. We used to manually scrub PII from training datasets. Now the LLM-powered detection catches things our regex rules never did."

Kevin Lin

CTO, NeuralForge AI

"Attorney-client privilege is non-negotiable. Piixie lets us share redacted case files with expert witnesses without any risk of the underlying PII leaking through a cloud service."

Elena Navarro

Head of Legal, Navarro & Ruiz Abogados

"We run Piixie on air-gapped networks for classified document processing. The fact that it works fully offline with a local LLM is exactly what government agencies need."

Luis Carlos Miño

CISO, Banco Iberia Digital

"The synthetic data mode is a game changer. We generate test fixtures that look real but contain zero actual customer data. QA loves it and compliance signed off instantly."

Anita Kapoor

VP Engineering, InsureTech Global

"GDPR audits used to terrify us. Now we run every customer-facing document through Piixie before it touches any external tool. Our DPO calls it the best investment we made this year."

Valentina Herrera

Compliance Director, GovTech Latam

"We pipe 10,000 documents a day through Piixie's CLI. The batch automation and server mode handle our volume without breaking a sweat. Setup took less than an hour."

Rafaela Santos

Data Engineer, DataBridge Brasil

"The quality of Piixie's synthetic data surprised us. It preserves document structure and relationships while every piece of PII is replaced with coherent fake data. Our ML team uses it daily."
