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.

See It In Action

From sensitive to safe, three ways.

The same patient intake form, anonymized by Piixie on a laptop. Pick a mode, then drag the divider to compare it with the original.

The original intake form with the patient's name, date of birth, SSN, home address, phone, email and insurance numbers
The intake form with personal data replaced by placeholder tokens such as [NAME_1], [DOB_1], [ID_1] and [EMAIL_1]

Real output from the Piixie app with its local Medium model. The form and everyone on it are fictional. Read more about redaction and placeholders or synthetic data.

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.

Supported formats: PDF, DOCX, XLSX, CSV, TXT, Markdown, JSON, XML, HTML, images, email and databases

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

Spreadsheets & Databases

Tables, anonymized column by column.

CSV, Excel and SQL dumps get a plan per column. Piixie recognizes names, emails, phones, birth dates and addresses, then regenerates every cell in code instead of asking a model to rewrite each row.

  • One generator per column, with a switch to keep IDs and keys untouched
  • Consistent within a file: the same value always becomes the same fake
  • Review in a grid and edit before you save
  • Save the plan as a template and it applies itself to the next export
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.

Piixie's pipeline: a raw document goes through text extraction and PII detection by the LLM, then one of three modes (Redact removes PII, Replace inserts placeholder tokens, Synthesize writes Faker-backed fake data) produces a safe copy to prompt, share, archive or test with

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."
