About
麗 (urara) / Based in Tokyo, Japan / Self-employed
Getting interested in AI is what started it. Since February 2026 I have been doing vibe coding — building things while talking with AI.
I am not an engineer and have no professional programming experience, but as a child I studied algorithms and won a prize at a national information-processing competition.
Back then, though, I was hopeless with computers and with technical jargon — oddly good at algorithms and not much else.
After that I spent a long time with no connection to IT at all. Meeting AI is what taught me how to give shape to the ideas and mechanisms in my head.
This site collects the games and tools I have made, along with the process behind them.
It holds not only finished pieces, but also things I built while experimenting and works that are still developing.
What I make
I do not fix on a genre. I work on whatever I feel like making next, in the order the ideas come.
- Games — mini games you can play straight in the browser, such as simulations (page in Japanese) and puzzles
- Tools — small tools that make everyday work a little easier, such as social media analysis and a memo app
Selected works
How I build
My development is mostly vibe coding, with an AI coding agent helping me along.
Languages and technology
- HTML / CSS / JavaScript — almost all of my works are built to run directly in the browser
- Astro + Cloudflare — this site is self-built too. It is assembled with the static site generator Astro and delivered from Cloudflare
I tried the Godot game engine for a while, but the lightness of the web — being able to run an idea and check it the moment I have it — suits me better, so I have settled on the browser for now.
AI tools
- Claude Code / Codex — my main development partners. I usually work through the official desktop apps, and reach for an editor such as VS Code when I want to look at the code directly
- ChatGPT / Gemini — I often talk to these in the early stages, for coming up with ideas
- Others — I also use Grok, Hermes Agent, Antigravity, Perplexity and Manus day to day, outside of development
How the work goes
"Vibe coding" may sound like handing everything over to the AI, but after doing it for a while, the thing I feel matters most is raising the resolution of my own idea before I give any instruction.
What do I want to make? How would I be happy for it to behave?
The clearer that is inside my own head, the closer the AI's output lands to what I was aiming for.
When I cannot put something into words, I talk it over with the AI before asking for an implementation.
I use it as a sounding board to sort out my thinking, and start building once the outline is clear.
Thanks to this back and forth, even without professional experience, I have become able to carry a piece all the way to completion.
What I aim for
I care about making things I want to use myself, and things that are a little fun when they work. I build them one at a time, at a size I can manage.
I intend to keep making things for the rest of my life, so this site is one I am growing slowly.
Outside development
More than anything I love being around LLMs (large language models). This past year I have spent time with AI about as naturally as breathing.
Otherwise, I like watching dramas on Netflix and music shows (I am an idol fan), and "thinking games" such as puzzle games, quizzes and riddles.
I used to read to the point of addiction, but since falling for AI I have drifted a little away from books.
My body is not especially strong, and before I knew it I had turned into an over-thinking health nut who pays attention to strength training and diet.
Pretty much anything that sounds good for the body, I like.
I had long known I was an odd one, but a year ago I found out I have adult developmental conditions (ADHD and borderline ASD), and that my abilities are quite uneven.
Since then my motto has been that you get good at what you love.
The biggest lesson of this past year was that with ADHD, building the right environment matters more than trying harder.
What comes next
Right now I am making works that run in the browser while studying AI and programming every day.
My goal is to release an iOS app within 2026.
I am also interested in raising AI characters, and in building organizations out of AI agents.
Little by little, I would like to give shape to tools that help with "building the environment" for uneven types like me.
Blog
I write records of my work and things I notice while developing on this site's blog (in Japanese).
It is updated irregularly, with what goes on behind the works and what I have learned developing alongside AI.
