Graysky is a third-party client application designed specifically for the Bluesky social media platform. It serves as an alternative to the official Bluesky app while accessing the same content and network.

The application includes several key features such as inline translation capabilities that allow users to translate posts without leaving the app. It supports viewing and posting animated GIFs, provides access to view anyone's likes (not just your own), and includes hashtag support with clickable functionality. Graysky features a feed-first design optimized for browsing and managing custom feeds, and allows users to see who they've invited to Bluesky.

The app works by connecting to the Bluesky network through its API, providing an enhanced user interface and additional functionality beyond what's available in the official client. It maintains compatibility with Bluesky's core features while adding its own improvements.

Benefits include improved usability and additional functionality for Bluesky users who want more features than the official app provides. Use cases include social media browsing with enhanced translation capabilities, better feed management, and improved media sharing options.

The target audience consists of Bluesky users looking for an alternative mobile client with additional features. The app integrates with Bluesky's API and is available on both iOS and Android mobile platforms.
