Every app I use is about 70% right. The last 30% never ships because the addressable market for it is one person -- me. So I built seven apps that are 100% right for one person, and I think that whole category of software is about to get eaten.

A dashboard and Model Context Protocol server for a project portfolio whose entire state lives in markdown files.
