See exactly what would leave your machine.
Nothing you paste here leaves this tab. Run the real detector, toggle to the redacted view, and see precisely which typed placeholders would cross the wire in your place.
Run the redactor right here, in your browser.
This is the real deterministic Tier-0 detector, the same code path the gateway runs, compiled to run client-side. Not a scripted animation. Paste your own text and watch what would actually leave on the wire.
What you paste never moves
The deterministic detector is compiled into this page and runs in your tab. There is no API call to score your text.
See what leaves on the wire
Toggle to the redacted view. Only typed <LABEL_NNN> placeholders cross the network; the real values stay here.
See why each span flagged
Every detection shows its label, rule, and confidence -- value-free provenance, so you can audit the decision and not just the result.
Summarize this note: client Daniel Brooks (SIN <GOVERNMENT_ID_001>), account <PAYMENT_CARD_001>, called <PHONE_NUMBER_001> to confirm his balance.
Why flagged (value-free provenance)
- <GOVERNMENT_ID_001>Gov ID / SINtier0:digit_run · conf 0.9 · luhn_ok
- <PAYMENT_CARD_001>Card numbertier0:digit_run · conf 0.7 · luhn_fail
- <PHONE_NUMBER_001>Phonetier0:phone · conf 0.85
This is Tier-0: deterministic, structured-PII detection (SIN, cards, IBAN, account IDs, phone, email, postal, dates) that runs with no model. Free-text names and addresses (for example Daniel Brooks above) need the on-device neural model. We never fake a detection Tier-0 did not make.
Three ways to prove it, right now.
Local is a claim that should be falsifiable. Each of these takes under a minute, and the exact result to expect is printed beside it.
Watch the Network tab
Open DevTools, switch to Network, then run a redaction above and watch for traffic.
Pull the plug
Turn off your wifi or go into airplane mode, then detect and redact the sample again.
Read the code
The detector is compiled into this page. The same core is open source on GitHub.
This is the floor. The on-device model goes deeper.
The browser demo is the deterministic Tier-0 layer. The full gateway adds the on-device neural model for names and free-text PII.
