MasterSelects
A browser-based media editor and an agent-friendly foundation for creative tools.
Edit video, mix audio, animate graphics, build 3D scenes, and work with live
visuals in one workspace with WebGPU rendering and a multitrack timeline.
Build while you create
Run MasterSelects locally from source and have a coding agent build the
effect, panel, or workflow your project needs. Try it in that same project,
refine it, and contribute useful additions so others can build on them.
The codebase includes architecture and feature documentation, reusable
components, automated tests, and a local agent bridge for editor control
and performance diagnostics.
The interface is optimized for touch and iPad, with phone workflows still
being refined. Editing and rendering run locally; hosted AI and media
generation use external services and may require credits.
The editor source is available under AGPL-3.0-only. MasterSelects is under
active development; keep backups of important projects.
Enable JavaScript and use a browser with WebGPU support to open the editor.
You can read about MasterSelects and the
documentation without JavaScript.
