About

Billy Xu

I’m someone who uses AI every day: to build products, make videos and handle everyday life, with one goal: make life a little better.

By trade I’m a software engineer with a background in test automation (SQA / SDET), so I like to confirm that something actually works. But this site isn’t about testing. It’s about what AI can genuinely do for an ordinary person.

PushSense is my first free app, built around my own need for voice dictation. Speech recognition runs on the Mac because that suits this product. Other ideas might become a tool, or simply an interaction worth playing with.

I’m exploring agent workflows across tools and platforms: clear tasks, useful handoffs, and checks against actual results. My writing records what I use, build, and learn, including product decisions, repairs, and personal observations. I’m also learning how to share what I make.
