About

Open-source MIT video editor running fully offline in browsers. Instead of slow UI simulation by browser automation, we built standardized Agent Skills to directly manipulate project files. Solving deployment pain points of large ONNX diffusion models on client-side WebGPU. Try live demo & view source on GitHub.

Behind Timeline Studio: AI Agent Skills Replace Slow Browser UI Automation

Hi everyone, I'm Martin, the maker of Timeline Studio. This open-source browser video editor runs fully local-first powered by WebGPU and ONNX Runtime Web.

Most AI editing tools only simulate UI clicks to operate timelines, which is slow and unstable when facing page loading exceptions. I built a set of standardized Agent Skills to let AI directly parse and modify native timeline project files, cutting redundant browser interaction overhead.

The project supports multi-track editing, audio separation, multilingual subtitles and offline WebM export. The full MIT licensed source code will be public when we launch on August 25. I m currently optimizing the loading & inference speed of large diffusion models inside the browser, and I welcome all technical discussions and suggestions here before launch.
