The Story

I'm not a developer. I built these anyway.

Built nights and weekends, by someone who isn't supposed to be able to do this.

I work shifts. Early starts at 4am, or lates that finish past 7. In the gaps, I build — using AI as my co-developer, learning everything as I go, and documenting it all so others can follow the same path.

"I don't have a problem with hard work. I just believe that at some point, it should start working for you too."

If you're AI-curious and worried about being left behind — that's exactly who this is for. Every tool on this site is proof that you don't need a computer science degree to ship.
