Prompt Flipper: Nifty one-click prompt sanitization

dev.to OpenSource2026-11-15 03:500 views

Hi everyone,

I've been working on a lightweight Windows open-source app called Prompt Flipper and wanted to share it here.

The main feature is one-click prompt sanitization.
It can detect PII and uses a local secrets database with Windows encryption to help remove sensitive information before copying or sharing prompts to any cloud ai chat session.

This tool runs offline.
No accounts, cloud services or telemetry.

It has a card-style interface for organizing and reusing (template) prompts stored as Markdown files.

I added a comic-style SANITIZE button and a funny nudge effect.
A 30 sec. video demo is in the Microsoft store.

Microsoft Store (free): https://apps.microsoft.com/detail/9PJSW6KZ5F63

GitHub: https://github.com/rckeller80/prompt-flipper

Feedback or coffee are welcome!
