I'm Chengtao Liang, an AI and data specialist. I build tools for my own training, money and everyday thinking. These are the ones I keep using.
A second brain. Notes, research and decisions kept as plain files that any model can pick up, so the context carries across models instead of being re-explained every time.
The workspace itself stays private. Here is the shape of a week in it.
Private workspace
One week, two models
example
A personal training app. The plan is updated automatically by AI in the back end. The front end is only what I need at the gym: the next session, the sets, and what I lifted last time.

Open Rack Runner
The week's plan, and the session it opens.
The one I use most

Every name and figure shown here is scrubbed demo data.
AI and data specialist, eight years across neuroscience research and commercial analytics. I've worked as a consultant across AI, analytics engineering, data analysis and research, and these days I help teams actually use AI and build the systems that make it stick.
The research years are where the habit of testing things properly comes from. Most of what's on this page started as something I wanted for myself and couldn't find.
If any of this is useful to you, I'd like to hear about it.
