thejaytea/writingtools is an AI writing assistant invoked through a system-wide shortcut on Windows, Linux, and macOS. The README describes it as an application inspired by Apple Intelligence's Writing Tools. The latest release is Win_v9+mac_OS_v6.1, the source code is written in Swift, and the license is GPL-3.0.
The core of this repository is a flow that applies AI directly to selected text. Pressing the global shortcut corrects grammar, rewrites the text or changes its tone, summarizes web pages, YouTube videos, documents, and more, and then lets you continue the conversation with that summary. It can use both cloud LLMs and local LLMs, and it also supports the free Gemini API. The macOS version is a native Swift port, and the GitHub star count is 2471.
However, the source contains no changelog describing what changed in this release, and no performance figures comparing it with other tools are given. Considering that the release name combines v9 for Windows and v6.1 for macOS, and taking the GPL-3.0 license terms into account, what can be confirmed right now is only the feature scope. The README and the star count do not reveal how much has improved or the actual quality, so it is better to postpone judgment until the app is installed and tried.
