Hi everyone, I’m Kenn, the builder of Privly Scrubber.
As someone working at the intersection of reliability and security, I’ve seen firsthand how AI tools can supercharge productivity, whether you're in tech support, healthcare, legal, marketing, or operations. But there's a catch: using AI often means pasting sensitive data into chat interfaces, and that can be risky.
I used to spend way too much time manually scrubbing logs and messages, removing emails, service names, database schemas, and other internal identifiers, just to make sure I wasn’t leaking anything confidential. It was tedious, error-prone, and frankly, a productivity killer. That’s why I built Privly Scrubber.
What Privly Scrubber does:
• Real-time protection: Monitors what you type or paste into AI tools and automatically redacts sensitive info.
• Local-first privacy: Everything happens on your device. No data ever leaves your machine.
• Smart redaction: Replaces sensitive terms with clear tokens like or , so your message stays readable and safe.
• Customizable: Easily add your own keywords, patterns, or team-specific terms, whether you're in finance, HR, or customer support.
Whether you're debugging logs, drafting client emails, or analyzing reports, Privly Scrubber helps you use AI confidently without compromising your data.
What makes it different:
• 100% client-side: Data never leaves your browser.
• Real-time detection.
• One-click actions: Mask, ignore, without breaking your flow.
• Customizable: You can add any data to flag and mask.
• Analytics: Weekly/monthly insights into your data protection.
What I’m proud of:
In this fast-moving AI era, my greatest pride is shipping a tool that protects data from leaks, while staying simple, fast, and secure. It solves a real, everyday pain point without adding friction.
Try it out and tell me what you think! Would love your feedback and ideas!
This is truely awesome! The whole "local-first privacy" thing is a huge plus for me—I'm always paranoid about sending sensitive info to any AI, so having everything happen on my device is a game changer. Ngl, that's a smart way to build trust. How customizable is it for, like, HIPAA compliance stuff?
