Open-source app recreates paid tool for cross-platform use

A developer has created an open-source, cross-platform application called Cooper, which replicates the functionality of the paid Mac-only application Copper by shadcn. Cooper aims to provide a free alternative for users on Windows, macOS, and Linux who find the original's $50 price tag prohibitive. The application allows users to quickly capture selected text, access a panel for notes or prompts, and organize information locally and privately. AI

IMPACT Provides a free, open-source alternative for a productivity tool that integrates with AI chat interfaces.
