Wow, thank you for featuring my article! ❤️

Super grateful to the DEV community for amplifying this important topic. Redacting PII before it hits any LLM is becoming essential.
Hope it helps lots of devs build safer AI flows!

Totally relatable. I saw one of my colleague simply copy pasting complete error logs directly to Chatgpt without even a second thought to get immediate solution to the issue and thereby giving away lot of sensitive user info logged.

Thank you so much! 🙏
PII leaking into LLM providers is a silent risk that most teams only discover after it's too late. Glad this resonated with you. If you ever try the API, I'd love to hear your feedback!

Looks like a important problem to solve! I wonder if a visual side by side input vs output might help website visitors visualize your product.

It's actually live here - See PII detection in action where you can see the demo which actually runs in the browser

We tried it and started using it in our workflow. So far it has been good in redacting the PII. Much needed one with all the AI chaos going on everywhere
