Steve Yegge shows Efrit, a tool that gives Claude full control of Emacs, on the Vibe Coding with Steve and Gene show. Claude opens info pages, runs shells and even draws a Mandelbrot fractal in a buffer.
Why Hacker News points people here: HN shares it as a fun demo of an LLM driving a live Emacs process and orchestrating its long-standing ecosystem.

“this is a fun watch”
Steve Yegge demos Efrit giving Claude access to Emacs.
For anyone else curious about what a practical loop implementation might look like, Steve Yegge YOLO-bootstrapped his 'Efrit' project using a few lines of Elisp: link And for more context on Efrit this is a fun watch: "When Steve Gives Claude Full Access To 50 Years of Emacs Capabilities" this video
Video on Yegge's Efrit, which drives Emacs with LLMs.
Another everything-is-new-again: link is Steve Yegge's drive-emacs-with-LLMs (I saw this mentioned via a video link elsewhere: this video )
“he demoed it here”
Yegge's demo of Efrit letting an LLM query a live Emacs process.
i also thought i can't get used to it, but i can! otherwise, as others have mentioned it, remap the keys! also, you can talk to some LLM about it, if you feel it would be tedious to come up with better bindings. feed in the key bindings from `C-h m` of eshell, enumerate which bindings you want to carry over from traditional shells and instruct it to recommend you binding swapping pairs. i was able to get great results on such niche operations already from anthropic's opus 4.5 models but even grok or deepseek was pretty helpful already last summer. steve yegge's efrit takes this to a whole new level, by letting the LLM interrogate your running Emacs process live for documentation or function source code: link he demoed it here: this video
