First Impressions
I pasted a complex C++ pointer function into Figstack, and it explained it to me in plain English. For learning new codebases or languages, this is incredible.
Best Feature: Explain Code
The 'Explain' button is the killer app here. It breaks down logic step-by-step. It also translates code—I converted a Python script to JavaScript instantly, and it actually worked.
The Verdict
It's not an IDE, but a companion tool. I keep it open in a tab when I'm reading legacy code I don't understand.
