About This Site

About the site

Ylyuriy is an independently developed collection of free web tools for the small everyday moments when you need to decide something. It has been online since 2025.
Twelve tools are available today: Word Roulette, Web Dice, Amidakuji, Bingo Machine, Team Shuffle, Prefecture Roulette, City Roulette, Gobi Roulette, Case Converter, Width Converter, Kana Converter, and Keyboard Tester (Prefecture Roulette, City Roulette and Gobi Roulette are available in Japanese only). All of them run entirely in your browser — no account, no installation.

About the operator

Ylyuriy

This is a one-person site. The planning, design, code, writing, and day-to-day operation are all my own work.
The guiding idea is simple — "Cute!!". I want these tools to lift your mood a little while you use them, not just get the job done.

Development notes and everyday writing live on the blog (in Japanese).

Principles behind the tools

• No sign-up, no installation
  You are never asked to create an account or install an app. Every tool is free, works the moment the page opens, and lets you close the tab whenever you are done.
• What you type is never sent to us
  The site is delivered as a static site with no server of its own. The words and names you enter, your draw history, and your settings are stored only in your own browser (local storage) and are never transmitted to our server.
• Motion is optional
  When your operating system is set to reduce motion, the spinning roulette and the line-tracing amidakuji animations are skipped. The results themselves are unaffected.
• Usable on any device, and by keyboard
  Every tool is built and checked to work the same way on phones, tablets, and desktops — and to be fully operable with a keyboard alone, without a mouse.
• Available in Japanese and English
  Most tools and pages are published in both Japanese and English, and you can switch between them at any time from the language selector in the header. A few tools are Japanese only because their source data has no English equivalent, and those are marked as such in the tool list.
