It works very well with VSCode. It has an integration. It shows differently than normal autocomplete, it shows just like gmail autocomplete (grayed out text sugggestion, and press tab to actually autocomplete). Sometimes the suggestion is just a couple tokens long, sometimes it’s an entire page of correct code.

Nice trick: write a comment describing quickly what your code will do (“// order an item on click”) and enjoy the complete suggested implementation !

Other nice trick: write the code yourself, and then just before your code, start a comment saying “// this code” and let copilot finishe the sentence with a judgement about your code like “// this code does not work in case x is negative”. Pretty fun !
