Glamorous Toolkit is built on Pharo, which I think is a fork of Squeak or shares lineage with it.
It's not about AI
Are you joking? GTK is not about AI either (though yeah they put LLMs in it if you want), it's another Smalltalk environment.
i mean look at the site linked. It's beating you over the head with AI immediately
They did turn the AI marketing dial way up on the landing page, but you should give the project a chance if you haven't seen it - it's by far the most modern Smalltalk browser and super fun to use. I only stopped using it on my random data explorations and for-fun coding sessions because it was quite heavy in RAM usage and I wanted something lighter (settled on good old emacs).
What do you use it for?
I used it to explore data since it has built in support for various data formats and easily made visualizations, but I haven’t used it in a few years because I thought it was using too much RAM for what it gave me (around 1GB to start with).
