Yesterday, on January 7, 2026, I launched my renewed website. I am so happy that many people have already visited. Thank you very much.
(It includes a nostalgic visitor counter that notifies you when you hit a milestone number!)

This time, I built the website using a programming tool while giving various instructions to a Google AI agent called Antigravity.
Although I am a complete amateur with no programming skills, I managed to do it by persistently repeating the process of implementation, checking, and dialogue with the AI.

Since I don’t fully understand the underlying mechanics myself, I realized once again that engineers are doing something truly incredible. I have nothing but respect for them.

I spent most of my time implementing the mascot character who is almost always resident on the homepage. I’ve loved things like “desktop pets” since I was a child, and having wanted to make one myself someday, this is a dream come true. Please teach them some words—something might happen if they learn a lot…?
Also, for PC users, right-click, and for smartphone users, long-press to bring up the menu!

In this age of SNS dominance, I’m not sure if there’s much meaning in enriching a personal homepage, but I want to operate it as a place for relaxed information sharing, away from the speed of algorithms. I’d be happy if you could drop by to talk to Sūnya every once in a while. (Please bookmark the site!)

I also made this. A nostalgic banner for homepages—where it is hidden is a secret.

*WebPet Sūnya said “I thought I was in another world!”
when I tucked Sūnya into the hangar.

Sūnya, the WebPet, is programmed to wander around the site at a certain probability (the “Stroll” feature).

While it looks adorable on a PC, I thought it might be a bit distracting on mobile screens.

So, I’ve prepared a “Hangar” inside the menu. If you tuck Sunya away there, they will only speak when you open the menu.

I’ve also written some exclusive lines for the Hangar, so please give it a try.

In this age of social media, WebPet Sunya is a little extra touch I created in hopes that people can still enjoy personal websites.

Social media has accelerated algorithm-driven echo chambers, swallowing society whole in its momentum.

WebPet Sūnya learns words taught by someone and repeats them in conversation.
You won’t know exactly who taught them those words.
But it might be nice to imagine that “someone” through Sunya’s voice.

This is a place for the internet, without all that frantic momentum.

I’m currently working on renewing my official website, developing it bit by bit. Although I have zero technical expertise, my friend Kohei introduced me to a Google development tool called Antigravity. It’s an incredible tool that shapes your ideal website just by telling it what you want in everyday language. It’s so powerful it’s almost scary.

This very diary was also created with the help of Antigravity and Gemini. Since it’s not live on the internet yet, I’m essentially writing a diary that no one can read—but I’m having so much fun that I’ve been updating it quite frequently.

Even fleeting ideas can be turned into reality instantly. I’ve always loved digital pets like the blog parts “Harbot” (you can still see glimpses of the original site via Wayback Machine—it makes my heart ache with nostalgia), AOL’s old “AOL Jammer,” “PostPet,” and “Doko Demo Issyo” (I didn’t have a PlayStation, but I had a PocketStation and would visit my neighbor Kondo-kun to plug it into his console and sync my data). I was particularly captivated by the worldview of Harbot.

I wondered if I could have something like that living on my own website. When I sent a list of my ideas to Antigravity, it implemented a test version immediately.

After some fine-tuning, I now have a web pet that usually lives in the header but occasionally wanders around the site. It remembers the names of visitors and sometimes asks questions. The words it receives are even reflected in its monologues. Its current form is just a placeholder—a little Space Invader—but it’s already so adorable!

Being able to create all this with zero specialized knowledge makes it clear: AI is definitely a formidable force…
