Clippie is designed for users who have to copy and paste from templates everyday. Define some clips in the app, and they'll always be there to be copied later.
You can download Clippie binaries for Mac (Intel and Apple Silicon), 64-bit Windows and 64-bit Linux from the Releases page. 32-bit Windows and Linux are not built due to low usage. However, because Clippie is an Electron-based app, feel free to clone the source code and run it on your computer in case you are a 32-bit Windows or Linux user. Just open Terminal and enter these very familiar commands, assuming you have NodeJS installed:
npm install
npm start
There's also a Chrome extension from GitHub and Chrome Web Store. Note that the desktop app and crx don't share data. You'll need to export and import JSON clips on your own to share the data between the two.
