Introducing PlasmaHex

Introducing PlasmaHex; a polished, browser-first collection of more than 100 practical tools. Search by name, task, common phrase, abbreviation or spelling variant; open a focused tool page, or jot down notes in the private notepad.

The catalogue covers text and writing, developer utilities, images, files and data, calculators, unit converters, colour tools and everyday helpers. The notepad opens as untitled.txt and offers 44 searchable language modes, including HTML, CSS, JavaScript, Markdown and Python. It provides syntax highlighting, autosaves drafts to this browser, and offers a preview only in HTML and Markdown modes. HTML preview is sandboxed; Markdown is rendered safely. Tool inputs and selected files are processed on-device wherever practical; notes are saved in this browser’s local storage, and code entered in the notepad is never executed.

Tool values and selected files remain in the browser. The notepad draft and selected language are saved locally on the current device. Copy and download actions are initiated by the user; there is no account or application server.

Hope you like it!
