About Me

Who I Am

I’m a Product Manager with more than 15 years of industry experience. Today, I build projects solo with AI-powered tools to bring this digital playground to life.

I’ll be sharing my thoughts and learnings from my entire journey right here on the blog.

KYOJOY grew out of my wish to build free, privacy-first tools that help people work efficiently and carve out breathing space amid packed work schedules. Every tool is built entirely with frontend tech, processing all files locally within your browser to guarantee top-tier data security and privacy.

My core mission is to deliver premium, no-login tools accessible to all users, with zero trade-offs in performance or safety. I firmly believe technology exists to empower users, not track their data.

My Story

What started out as a side project to craft handy lightweight tools has grown into KYOJOY: a suite of free, registration-free utilities tailored for today’s working professionals.

This journey was sparked by a straightforward question: Why do most online tools force users to sign up or upload personal files to third-party servers? Motivated by that thought, I set out to build better alternatives that prioritize user privacy without sacrificing robust functionality.
