You have to fill in some gaps (and occasional paranthesis) but it’s pretty darn good at writing elisp for improving your config. I find it’s helpful enough that you can take on medium hanging fruit that you wouldn’t attempt otherwise.

For example, I wrote a minor mode for centering text, an org-export backend for Notion, and some plumbing for chatgpt-shell.
