๐Ÿ’กWhat is Timeline Studio?

Timeline Studio is a browser-based local-first editor built around a real multi-track timeline rather than a prompt-only video generator. It includes automatic captions, multilingual voiceover, AI repair, visual analysis, music tools and deterministic offline export. The project uses browser technologies such as WebGPU and WebAssembly so much of the workflow can stay on the user's machine. It is useful for creators who want AI assistance without automatically uploading their footage to a cloud editor. The project is MIT licensed, although individual models and third-party components can have their own terms. Because the project is actively changing, users should check the current release for the exact AI models available and the hardware supported by their browser. It is a strong free option for creators who want a modern browser editing experience with local AI features.
