Original Summary

This past week I built (prompted) a tool I find myself using day to day and wanted to share it with others who may find it useful as well.<p>“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.<p>Demo: <a href="https:&#x2F;&#x2F;jackdamon.org&#x2F;assets&#x2F;images&#x2F;lacuna-scheduling-demo.gif" rel="nofollow">https:&#x2F;&#x2F;jackdamon.org&#x2F;assets&#x2F;images&#x2F;lacuna-scheduling-demo.g...</a><p>Example scheduling workflow using Lacuna’s native UI and sample suggestions.<p>So far I find myself frequently using it when drafting emails where I want help with quick phrasing.<p>The project was inspired by Rectangle, an open source utility app for window tiling that is keyboard based.<p>Lacuna is open source and available here: <a href="https:&#x2F;&#x2F;github.com&#x2F;jdamon96&#x2F;lacuna" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;jdamon96&#x2F;lacuna</a><p>Blog: <a href="https:&#x2F;&#x2F;jackdamon.org&#x2F;blog&#x2F;lacuna&#x2F;" rel="nofollow">https:&#x2F;&#x2F;jackdamon.org&#x2F;blog&#x2F;lacuna&#x2F;</a>
