Which is not runnable in the first place. Interesting though, as this shows exactly the problem. It looks legit, but it's some generated fake text.

  It tends to invent whole fake packages.

    Yup, I got some nice documentation (minor syntax error) for a Http package in Lean that doesn't exist. I asked about Lean4 and it helpfully explained that the non-existent package had moved from Lean to Std.

I just tested it on a little snippet of my code obfuscated with https://obfuscator.io/ https://obfuscator.io/ and it worked almost perfectly. My original code: function resizeImage(img) { var maxHeight = 350; var ratio = 1; if(img.height > maxHeight) { ratio = maxHeight / img.height; } var width = img.width * ratio var height = img.height * ratio; var canvas = document.createElement('canvas'); canvas.height = height; canvas.width = width; var ctx = canvas.getContext('2d'); ctx.drawImage(img, 0, 0, width, height); return canvas.toDataURL("image/jpeg", 0.8); } ChatGPT's answer: https://i.imgur.com/5jgPMEd.png https://i.imgur.com/5jgPMEd.png

  Interesting why it changes 350px to 600px. Also interesting is how it's explanation of the deobfuscated code, although broadly correct in terms of goal, doesn't accurately describe the steps. Almost as if it's disregarding the code altogether and merely describing another implementation of "resizeImage".

  Interesting, I tried it on the sample code at https://obfuscator.io https://obfuscator.io, which was just: function hi() { console.log("Hello World!"); } hi(); ChatGPT was unable to deobfuscate. Here's the answer: https://i.imgur.com/20XhPw6.png https://i.imgur.com/20XhPw6.png
