Why this site exists
rev. 2026-11-12I work in IT and I'm a tech enthusiast. This is where I collect the everyday tools I need for work and for the rest of life. Right now that means the Anagram Solver, the Unit Converter, the JSON Formatter & Validator and the Team Generator.
When a new need or challenge comes up, I build a tool for it and add it here. I'm sharing them because I'm probably not the only person who needs them, and the goal is a free repository of tools that anyone can use. They run in your browser, so what you type stays on your device.
Each tool has plain-English notes and worked examples, the guides go deeper, and the changelog shows what has changed. There is more on the About page, or tell me which tool you would like next.
