Ameko is an open-source, cross-platform subtitle editing suite designed for creating, styling, and managing Advanced Substation Alpha (ASS) subtitles. It provides integrated audio and video playback for previewing subtitles with accurate timing and rendering. Users can load reference subtitle files and automatically view overlapping lines while editing translations. A tabbed workspace supports multiple subtitle projects with independent media files. Project management tools centralize shared styles, colors, spell-checking settings, and terminology lists. The application also includes subtitle rendering performance analysis and integrated Git version control. Advanced automation is available through C# scripting, NuGet packages, and limited JavaScript support. Ameko runs on Windows, macOS, and Linux.
