It's still in development. I built a proof-of-concept from scratch almost a year ago, which I just open-sourced at the following link.

I intend to develop it a bit more and host it online.

A previous prototype, really barebones, is at https://expensed.me.

The idea is to drag and drop (or type) a plain-text note and visualize the data as a scatterplot or other charts.
