karthink/gptel-quick is an Emacs package to do quick LLM lookups of selected region.
On <2025-06-12 Thu> I installed it using this snippet:
(use-package gptel-quick :ensure t :vc (:url "https://github.com/karthink/gptel-quick" :branch "master") :bind (("C-c j l" . gptel-quick)))
Now, when I select a region and press {C-c j l}, gptel-quick opens a posframe at point with short explaination of the term. Works well, akin to built-in macOS feature "Lookup", but powered by LLM hense can give context-aware answers.
Check videos in karthink/gptel-quick, they are good.
