A year ago I was using claude and found it unexpectedly blowing-away already-settled code. I found this frustrating and just wanted to drop a "save point" where I could compare the before and after versions of certain files. So I built a little utility called "bup" that tarballs the whole code tree and gives it a unique name. It ignores prior backups and has options to ignore certain subdirectories, VCS directories, artifact directories, or secrets files. And you can add a single switch (-s) to create a shell script that automatically backs-up the current project. Yes I can use git for this, but this is honestly way easier, especially if I want to compare/edit different versions. No names. No files. No trees. Just "bup .". And it's 100% bash. https://github.com/maxk42/bup

I'm probably the only one who'll ever use it but I like it.

I built https://www.ironvolume.com/ to help plan workouts for crossfit, hyrox and building it out for athx.

https://tajd.github.io/cofferdam/ - is an experimental compile time time checker that can be run for typescript/rust to be able to impose architecture, design principles that can be forgotten by agents. The goal is to be able to make it possible for an agent to be reminded about design conventions where it forgets, so it reduces the amount of context that needs to be used initially to define those sorts of conventions.

I tool which pulls all details from my Garmin and keeps a '5 day rolling average' series of stats -- my lifestyle means I can't keep up 'X steps a day', but I feel I can keep up 'average X steps a day for the last 5 days'. What's perfect is I can tweak it, I even added a special 'the weather is truely awful today, you can dip under average but you need to make it up later' option by getting it to automatically pull the weather forecast, or 'The weather is perfect today, really push'.

I built several prediction models for the market price of gold and cryptocurrencies. But this is always more a fun task than serious stuff - you can't trade with it. Yes, I think it would be possible, but not w/o having the hardware and data resources. I also built a music player with an LLM agent, helping finding the right tracks.

Mostly games-adjacent hobby tools, it turns out.

An app to let my friends and m…

Games stuff for me too - geoguessr in my case. It'd never have been worth putting in the time to build them without AI but so easy with AI.
