I shipped a free Mac app today: ModelKeeper: Your AI Cleanup Assistiant

Here's the problem it solves. If you've tried more than one local AI tool, Ollama, LM Studio, Jan, GPT4All, whatever, there's a good chance you've downloaded the same multi-gigabyte model more than once without ever knowing it.

And if you've ever uninstalled one of those apps, the model files it left behind are still sitting on your drive. The app is gone. The disk space isn't.

ModelKeeper finds every local AI model on your Mac, tells you exactly how much space each source is using, flags likely duplicates across tools, and calls out orphaned models from apps you don't even have installed anymore. Every delete goes to Trash first, nothing is permanent, so there's no risk in cleaning house.

It's free. Direct download, no App Store required.

This is a companion to the rest of the Ochre lineup, built the same way everything else at Ochre gets built: solve one problem completely, don't force anything on you that you didn't ask for.
