melvin-abraham/google-assistant-unofficial-desktop-client

This project brings Google Assistant to desktop computers running Windows, macOS, or Linux. It is an unofficial app, meaning it was built by an independent developer using Google's publicly available Assistant software kit, not by Google itself. The design takes visual cues from the Google Assistant interface found on Chrome OS, and it offers both a light mode and a dark mode. To get it running, you download an installer for your platform (or build it from source if you prefer). On Windows you can use the winget package manager, on macOS you can use Homebrew, and on Linux you can install it through the Snap store. All three platforms also receive pre-release preview builds if you want to try features before they are fully stable. Before the app can talk to Google, you need to complete a one-time setup called Device Registration. This process creates a Key File and a Token that prove your identity to Google's servers. The README points you to a step-by-step wiki for this process. Once you have those files, you set their locations in the app's Settings screen and you are ready to go. The default keyboard shortcut to open the assistant is Win plus Shift plus A on Windows, Cmd plus Shift plus A on macOS, or Super plus Shift plus A on Linux, though this can be changed in Settings. Under the hood the app uses Electron, a tool that lets web technologies run as a native desktop window. It also uses a library called p5.js to draw a visual animation while you speak into the microphone, another library to play audio responses through your speakers, and a wake-word library (based on Porcupine) that lets the app listen for a trigger phrase without you pressing any button. The project is still under active development and welcomes outside contributions. You can report bugs, suggest features, improve documentation, or submit code changes through the GitHub repository.
