In plain English

Parabolic is a desktop application that lets you download video and audio from a wide range of websites. It provides a graphical interface on top of yt-dlp, a popular command-line download tool, so you can use all that functionality without typing any commands. The app is available on Linux, Windows, and macOS, and optional browser extensions for Firefox and Chrome let you send links directly from your browser to the app. When downloading, you can choose the format you want: video files in mp4 or webm, audio files in mp3, opus, flac, or wav. The app supports downloading subtitles and metadata alongside the video, and you can run multiple downloads at the same time rather than waiting for one to finish before starting the next. On Linux, the app is distributed through Flathub, which is a standard software store for Linux desktops. On Windows and macOS, you download it directly from the GitHub releases page. The Linux version uses the GNOME desktop style (the same look as many built-in apps on Ubuntu and Fedora), while the Windows version uses the native Windows interface called WinUI. Screenshots in the README show a clean home screen, a downloads-in-progress view, and a dark mode option. The project is built with .NET 10 and C#, and the README includes instructions for building it from source if you want to compile it yourself. Translations are managed through Weblate, so contributors can add or improve support for different languages without touching the code. The README includes a legal note that videos on YouTube and other sites may be protected by copyright, and the developers do not take responsibility for how you use the tool. Downloading content you do not have the rights to may violate the terms of those platforms.
