Frequently Asked Questions
What types of PII does this tool detect?
The tool detects person names, organizations, locations (via AI NER model), plus emails, phone numbers, Social Security numbers, credit card numbers, IP addresses, dates, and US ZIP codes (via pattern matching). Both AI and pattern-based detection run entirely in your browser.
Is my data safe and private?
Absolutely. The AI model runs 100% on your device. No data is uploaded to any server. Your sensitive information never leaves your browser — that is the whole point of on-device AI.
What is the difference between AI Mode and Basic Mode?
AI Mode uses a named entity recognition (NER) model to detect person names, organizations, and locations in context — things that regex alone cannot reliably find. Basic Mode uses pattern matching only (emails, phones, SSNs, etc.) and works instantly without downloading a model.
What redaction options are available?
You can replace PII with a type label like [PERSON] or [EMAIL], mask it with asterisks (J*** D**), or remove it entirely. The redacted text can be copied or downloaded.
Can SimpleDataFoundry detect PII at scale?
Yes. SimpleDataFoundry can apply PII detection and redaction rules to your data pipelines automatically — scanning millions of rows as they flow between your sources and destinations. Connect your databases, APIs, or data lakes and apply privacy rules without manual work.
Does this work with non-English text?
The AI NER model works best with English text. Pattern matching (emails, phone numbers, etc.) works with any language. For multilingual PII detection at scale, SimpleDataFoundry supports additional models and custom rules.
