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, plain-text-first notepad. The catalogue covers text and writing, developer utilities, images, files and data, calculators, unit converters, colour tools and everyday helpers.

PlasmaHex started because all the tiny digital jobs we do every day were taking far longer than they should. I got tired of bouncing between slow, cluttered sites just to count words, validate JSON, resize an image or convert a colour, so I built my own tools and kept going. That little collection turned into PlasmaHex: one fast, clean, private place for all those in‑between tasks. No sign up, no tracking, no fuss. Just tools that work instantly and keep you moving. If it makes your day smoother, have a look round and try a few more - you’ll see what I mean.

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.
