blank.tools is a free browser-based utility that enables you to turn sensitive information into alphanumeric tokens before sharing it with AI systems and later replace tokens by original data again. No servers - everything happens locally in your browser.

This is a simple idea with a serious goal: protect your data before feeding it to AI. It’s free, open to feedback, and designed to work 100% locally in your browser. For now it is almost completely based on regex, but I plan to change that soon and add NER and other methods to make it more reliable. It is in beta stage so I am open to your feedback and remarks.
