Ai Video Editor

Ai Video Editor is listed under the name Timeline Studio, a free video editor that runs entirely in the browser. It combines AI voice generation, automatic captions, talking portraits and a multitrack timeline in one installable web app. The company describes it as local first: core editing and model inference run on the user's own device, and model files are downloaded on demand and cached for repeat use. The AI features include multilingual voiceovers, automatic captions using Whisper running in a WebAssembly worker, browser based music generation through WebGPU, and talking portraits that animate a face from audio. A repair set handles object and watermark removal, video restoration and denoising. Subject and depth analysis supports cutouts, outlines, smart framing and photo parallax. On the editing side there are visual keyframes for scale, position, rotation and opacity, rectangle, rounded rectangle and circular masks, filters, transitions, clip speed control, and a choice of whether extracted audio stays linked to its clip. It suits creators, educators and small teams who want captions, voiceovers and quick edits without uploading footage to a server. Export is available as MP4 and WebM. Pricing as published shows a free tier at USD 0, and the structured data on the pricing page lists no paid plan. Because the page is rendered with JavaScript, no further plan detail could be read, so anyone planning heavy use should confirm on the site. Local inference needs a capable device and a browser with WebGPU support.
