I build free online tools at ToolMixr and write honest AI tool reviews at GenAIPick. I also document the entire journey — from zero traffic to AdSense rejections — at lusdaily.com in Chinese. Before this, I was that person with 15 browser tabs open, each running a different "free" tool that required an account, uploaded my data, or hit me with a paywall. So I built what I wanted: tools that just work, right in your browser.

The Full Story

I started building web tools because I got tired of using free online tools that collected my data, showed too many ads, or asked me to sign up just to format some JSON.

ToolMixr was the result — every tool runs entirely in your browser. Your data never leaves your device. Your passwords, JSON, images, and financial data stay private.

Then I started GenAIPick because I noticed most AI tool reviews were either sponsored, outdated, or written by someone who clearly had not actually tested the product. I pay for my own subscriptions and write honest reviews of the tools I genuinely use.

When I am not building tools or testing AI, I am probably reading about local AI models, tweaking my home server, or playing with the latest open source AI releases.
