“Lacuna” is an opinionated way to invoke LLMs into any text input on your Mac. Specifically, you can type bracketed phrases {such as this}, press Shift-Command-K (or a different shortcut of your choosing), and the tool sends your bracketed phrase + the surrounding text contents to an LLM of your configuration for generating text to replace the bracketed phrase. The program returns 3 candidate phrases and the experience is entirely keyboard navigable.

So far I find myself frequently using it when drafting emails where I want help with quick phrasing.
The project was inspired by Rectangle, an open source utility app for window tiling that is keyboard based.
