The Randomize mode

Instead of obvious [REDACTED], a credit card become another Luhn-valid but fake card, email become [email protected], IP become 203.0.113.x. The AI or form still get proper input — just not your real data.

Four ways to react

Off

Stay out of the way.

Warn

Mask

Change each secret to a [[PLACEHOLDER]].

Randomize

Swap each secret for realistic fake data.

Every structured match got validated locally, so normal text like order number or version string sure no kena touched.
