Despite feeling conflicted in a few ways about it, I (José) have been using LLMs to help with coding since May or June of last year. I recently went into a bit of a coding binge with LLM support, and one of the results is this, a Glyphs plugin called Interpol (https://github.com/Dogray-Type-Foundry/Interpol).

It's basically a plugin to preview interpolations, with a a couple of different way to navigate through the design space. The interpolations can be shown, again, in a few different ways, some which I haven't seen used in any other similar plugins. It can also highlight points that are kinking, and by how much, and tries to provide a way to help resolve those kinks.
