Neither of those seem similar to GitHub copilot other than that they can reduce keystrokes for some common tasks. The actual applicability of them seems narrow. Frequently I use GitHub copilot for “implement this function based on this doc comment I wrote” or “write docs for this class/function”. It’s the natural language component that makes the LLM approach useful.
There is also auto doc generators.
I think what you’re specifically referring to is accessibility or ease of use. For someone unfamiliar with those tools, I can see the appeal.
Personally, as a software dev, I think it’s just very inefficient way to accomplish this goal. LLMs consume vastly more resources than a simple script. So I wouldn’t use it, especially if I’m paying real money for it.
