Most AI video tools begin with an upload button.
That is convenient for the application developer, but it changes the product for the user. Raw footage can be large, personal, slow to transfer, and expensive to process repeatedly. For a video editor, uploading is not a one-time action either: every trim, caption, effect, and export can create another round trip.
I wanted to explore a different constraint: how much of an AI video-editing workflow can stay inside a modern browser?
That question became Timeline Studio, an open-source, local-first AI video editor with a multi-track timeline, captions, voiceovers, visual effects, browser AI tools, and offline export.
The interesting part was not putting a familiar editor UI on a webpage. It was making media, AI inference, model delivery, timeline state, preview, and export behave like one coherent system.
