Diffusion Studio is a browser-based video editor and creative suite that combines an infinite canvas with a timeline, enabling design-tool-like freedom and 4K exports. It includes built-in AI features, a local-like workflow, and a vision for desktop AI integration coming soon.

A single, in-browser editing workspace that starts from an infinite canvas and transitions to a timeline editing flow. Users import assets, arrange scenes on the canvas, then edit on a timeline with precise property controls (timing, position, scale, layout) and integrated effects and audio. The editor supports 4K export with no proxies, AI-powered generation and actions, context-aware tools, and a unified workspace from import to export. Plans include a free tier with AI trial credits and a Pro tier with additional AI models, credits, and priority support; a macOS app with MCP support and desktop AI agent collaboration is planned for the future.

Figma for Video Editing using Webcodecs Browser Acceleration

Diffusion Studio offers an in-browser AI-powered video editing app that uses Webcodecs and WebGPU to encode, process, and decode video with hardware acceleration. It automates editing tasks (e.g., removing filler words, pauses, and repetitive sections) and allows edits via transcript or timeline without uploading files.
