Detect and redact PII instantly
One API call strips names, emails, phone numbers, SSNs, and 36 other entity types from text, JSON, and CSV — no training or configuration required.
What is Redactly?
Redactly is a PII detection and redaction API for teams that handle sensitive text, JSON, and CSV data. It uses a custom model fine-tuned for AI labs to find 40 entity types — names, emails, phone numbers, SSNs, addresses, card numbers — and redacts them in a single HTTP call, with no training, regex, or configuration required.
{
"text": "Held for Jane Doe, 555-867-5309,
jane@acme.example",
"style": "replace",
"webhook_url": "https://acme.example/hooks"
}
webhook_url and the full response is POSTed to your endpoint after redaction. No queue or worker to run.How does Redactly work?
Send text or a file to a single endpoint. Redactly returns your content with sensitive spans replaced, masked, or removed, plus the entity list with exact offsets.
40 entity types, one label set
Names, contact details, card numbers, IBANs, credentials, health data, and the special categories. Formats with a checksum are validated by pattern; free-text types such as names and conditions use the model. Every hit returns the same dotted label.
Replace, mask, or remove
Replace keeps the text readable for a reviewer, mask holds the original length so log alignment survives, and remove deletes the span when the field has to come back empty. Set it per request with the style field.
"text": "Call Jane Doe on 555-867-5309",
"style": "replace"
}
Send text, get labeled output
The response contains the redacted text, the original, and one object per span with its type, text, and offsets. Log those responses wherever you already keep records: the request text is processed in memory and never stored.
JSON, CSV, and delivery
Upload a .json or .csv file and get the redacted file back. JSON is walked recursively so every string value is covered; CSV is redacted cell by cell with the table intact. Add webhook_url and the response is POSTed to your endpoint.

One POST endpoint. If your tool can make an HTTP request, it can redact. See the integration guides.
How much does Redactly cost?
For a single product or pipeline that needs accurate PII detection without a platform build.

- Security questionnaire and DPA support
How does Redactly compare?
Two alternatives come up in every evaluation: a cloud NLP service, and hand-written rules. Each one leaves you maintaining something.
vs AWS Comprehend Medical
It finds PHI, then hands the problem back to you.
- Returns character offsets, so you write the redaction step
- 20,000 characters per call, English clinical text only
- Medical notes only — no customer, HR, or financial records
vs regex rules
Patterns match shapes, so the rule set never ends.
- Cannot find names, addresses, or free-form record numbers
- Misses formatting variants and over-redacts lookalike IDs
- Every new format is another rule, a test, and a regression
Frequently asked questions
Short, factual answers about detection coverage, integrations, onboarding, and plans.
Can Redactly integrate with our existing tools?
Redactly is a REST API, so it works with any language or platform that can make an HTTP request. There are guides for Python, Node.js, curl, n8n, Postman, and LangChain, and webhooks can push results to your own endpoint.
What types of PII does Redactly detect?
Redactly detects names, email addresses, phone numbers, SSNs, home addresses, dates of birth, IBANs, IP addresses, and 33 more types — 40 in total, out of the box, no training required.
How long does it take to see results?
One request. Ask for a key, then POST your first document — the API is ready immediately, with no configuration or model training.
What types of companies work with Redactly?
Redactly is built for teams that handle personal data — healthcare, finance, legal, and software — and the API makes no assumptions about your stack or language.
Does Redactly offer one-time use or ongoing plans?
Plans are billed monthly and can be cancelled at any time. The free playground covers occasional short pastes without a key.
What does onboarding look like?
Request a key, then POST your first document. Nothing to install or train. Larger deployments can get help wiring the first integration.
