Airy is software developed by Eltima Software for downloading videos from YouTube.
The first version of the product was released in 2013. Written in Objective C it was a basic downloading tool that could process one video at a time.[unreliable source?]CNET staff in their review says that "It has a very streamlined interface with just a couple of options and a copy/paste mechanic."  Additional functionality was added including the capacity to download a few files simultaneously by copy-pasting links in a text editor. The app can convert downloaded content into a format and resolution of user's choice – HD, SD and low definition. The app is capable of extracting audio files from videos. Starting from version 2.0 the app can download entire YouTube playlists.
Initially developed for Mac OS, Airy also supports Windows.
