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.

I would like to acknowledge that this would not exist without the work of @simoncozens , @harbortype , @ryan and @letterror. For Glyphs, there's one other tool that does something similar, Variable Font Preview 3 by @mark2mark, which is certainly more professionally made and will likely be much better supported in the long run. I did consciously and actively avoided replicating things that are unique to that tool.
Now, I mentioned LLMs at the beginning. I won't justify my use of them. But this tool would not exist without them. I do have a full-on impostor syndrome about it, because yeah, I didn't write all the code that's in there. So many of the great ideas are taken from other's work too. So I don't feel like I own this. It exists because I wanted it to exist, and it's informed by the things I wanted it to do, that's kind of it.
@dogray That’s very nice! I’ll try it on a few projects soon ;)
