Repiano

In 2025 I built "Repiano" as a prototype of a generic decision-making app — you describe the options you're weighing and the things you care about, and it helps you score them against each other. (This isn't an itch I'm done scratching... I still feel like multi-factorial searches is an important missing feature, as if it was something meant to be discovered in 1980 and built into computing like pagination and windowing but just was missed somehow.)

It was an excuse to start learning about writing code with AI, back when the models were just getting to the point that they weren't excellent auto-completes anymore. The app itself I paused, as while it was successful for a while for my workout routines, as I expanded to more prototypes I realized that data entry (and even more important maintainance) was going to be a limiting factor in how much trust would be built into the system and how much cost for questionable benefit would be spent.

Here it is in the state I got it to:

• The app
• The docs, including a couple of examples that start showing off rules.

Not sure I think it's worth a human read the docs and such, but (assuming the requests aren't blocked), do throw your LLM of choice at it and play around with it that way if you want.
