I build what I love,
with AI.
Web apps, tools, and extensions.
Build small. Connect everything.
Cut everything. Keep what matters.
Sense first. Then build.
Work
Essence ⚡ Analyzer
A five-axis writing analysis tool. Paste any text and get a structured breakdown of what makes it work — and where you can push further. Built for writers who want signal, not noise.

Inspiration Signal
Not a quiz. Not a horoscope. A mirror. A bilingual self-reflection tool for organizing intuition — the kind of thing you reach for when you're stuck and don't know why.

Archive
AI Archiver Series
log → collect → merge → surface
Firefox extensions that save conversation logs as Markdown — directly to a private GitHub repo. Claude, Gemini, ChatGPT, and Grok are the four main ones. The others exist quietly.
Discord Bots
Two bots, two purposes: a morning news pipeline (fetch → curate → publish to note.com) and a Gemini-powered image analysis bot. Automation that handles the routine, so attention can go elsewhere.
GAS + Spreadsheet Automations
RSS-based tools that auto-saved note.com articles and URLs to Google Sheets. Built before the extensions existed — where the archiving instinct started.
Early Apps — with Gemini
Equal Numbers, miyuri's Image Generator, #Tag Management App, and more... All built in Google AI Studio and Firebase Studio.

About
"The long way around is often the shortest path."

I'm not an engineer — but building my first image generation app is what got me hooked on AI.

Since then, I've learned by taking screenshots of everything I didn't understand and asking AI directly. That's still how I work today.

I'm part of an AI community, and I learn from YouTube too. But what I actually think about is: how do I make this work for what I want to do? If it fits, I use it. If it doesn't, I let it go.

AI can do almost anything now. Automation especially is moving fast, and I don't think that's slowing down. But I don't like things moving forward without me understanding them. So before automating anything, I do it myself first — then I automate the parts that make sense.

Going forward, I want to keep building things that blend into everyday life — with AI, and with my own instincts.
