How to mask PII before using AI chat at work

Addresses the real workflow problem most compliance conversations skip: people are already pasting customer data into AI chat tools every day, and a policy memo is not going to stop them. The post walks through PII detection and substitution techniques that sit between the user and the model, so the actual content still gets processed usefully without raw identifiers leaving the building. It is a blog post attached to a product, which means the worked examples trend toward that product's approach rather than a neutral survey of options. Still, the framing is concrete enough to be useful as a starting point for a SaaS team trying to write an internal policy or evaluate a middleware layer. The honest reservation: the advice is fairly surface-level for anyone already running a data-handling compliance process. It is better as a primer for a non-technical ops lead than a technical architecture guide. -> Best for: SaaS team of 2-5 that needs a first-pass PII policy before their support team goes further with AI tooling.
