Detect and redact PII
in any text.
One API call finds names, emails, phones, addresses and secrets in 30+ languages — and hands back clean, masked text. We run the model ourselves, so there's no per-token AI tax, pricing is flat, and your data never touches a third-party LLM.

How it works
PII detection and redaction in two endpoints.
POST /v1/detect
Returns every PII span with label, byte offsets and a confidence score.
{ "entities": [
{ "label": "EMAIL",
"start": 20, "end": 36,
"score": 0.99 } ],
"count": 1, "ms": 31 }POST /v1/redact
Returns your text with every span masked as LABEL — ready to log, store or send to an LLM.
{ "redacted":
"Contact [FIRSTNAME] at
[EMAIL].",
"count": 2, "ms": 28 }PII redaction software, minus the enterprise tax.

Questions
What counts as PII? +
Sanitext detects personal data: first and last names, email addresses, phone numbers, postal addresses, dates, URLs, account and card numbers, and secrets like API keys and tokens — in 30+ languages. Each is returned as a labeled span with exact byte offsets.
Detection or redaction — which do I get? +
Both. POST /v1/detect returns the spans; POST /v1/redact hands back your text with every span masked as [LABEL]. Same call, your choice.
Is my text stored? +
No. We log request metadata only — character counts, entity counts and timing — never your text or the PII itself.
How fast is it? +
Short inputs (1–3 pages) return in well under a second. Large documents take longer; the Scale and Enterprise tiers add an async bulk endpoint for them.
How is this cheaper than AWS or Azure? +
We run the open-weights model on our own infrastructure, so we pay no per-token AI fees — and we pass that on. Flat tiers, overage up to 2× cheaper, and a permanent free tier.
Is this GDPR or HIPAA compliance? +
It is a redaction and data-minimization aid, not an anonymization or compliance guarantee. Use it as part of a broader privacy-by-design approach. EU residency and a signed DPA are available on Enterprise.
