Undefined Platform
iS2.net, an ever-evolving Undefined Platform where practicality meets curiosity.
Since its founding in 2001, we’ve been collecting and creating simple, powerful tools that solve real problems—whether it’s a quick calculator, a data converter, or a niche utility no one else thought to build.
Everything here starts with a spark of usefulness: an idea that seems small but can save time, clarify thinking, or just make life a little easier.
You’re invited to explore, use, and even shape what comes next. Have an idea? Submit a request, and if it fits our vision, we’ll build it—free for you and everyone else to benefit from.
About iS2.net
At its core, is2.net (short for iScandium², or the square of iScandium × iScandium) is a project of iScandium Smart Space Alliance Ltd., founded by Mark Cheng with a simple belief:
Tools should be accessible, transparent, and user-driven.
Once a tool is live, it runs entirely in your browser—no servers, no tracking, no cost. You’re in control. Download the code, tweak it with AI, or rebuild it from scratch.
This isn’t just a toolbox—it’s an open workshop. Your input helps decide what gets built, and your creativity decides how far it goes.

Frequently Asked Questions
What is this website about?
This website is a growing collection of simple, practical tools that I create whenever I think of something useful for everyday needs.
How much does tools cost?
Most tools are generated with AI at virtually no cost to develop, so they’ll always remain completely free to use.
What technology is used to do the calculation?
I use AI to generate JavaScript code for the calculators. All computations run 100% in your browser on your device, leaving no usage data or traces on the server.
Can I customize my own calculator with you?
Yes! You can also download the full source code and modify it yourself—with AI’s help if you’d like. Or you can email me for help
