The Garble Text plugin allows users to obfuscate all content within Obsidian, turning text into unreadable characters and blurring images, providing a secure way to take screenshots without revealing sensitive information. The plugin's garbled text can be revealed simply by hovering over it, ensuring that it remains hidden when not needed. It can be activated through the commands palette, offering a quick toggle feature. The plugin also includes planned improvements, such as regex-based garbling and custom display fonts for garbled text, enhancing its versatility for privacy-conscious users.
