About the project
Professional timeline editing, built for browser AI
Timeline Studio is an open-source experiment in bringing serious media editing and modern ONNX inference into a single browser workspace. It is local-first, installable and designed around a multi-track timeline rather than a one-click template flow.

What “local-first” means here
Editing operations and project-media processing are designed to happen in the browser. Large model files still need to be downloaded, and browser capabilities determine which AI and export paths are available. The project documents these limits instead of presenting remote or simulated output as local inference.
