# VideoSOS

> Open-source browser-based AI video editor powered by 100+ models

VideoSOS is a privacy-first, browser-based video editor that integrates over 100 AI models for text-to-video, image-to-video, image generation, editing, and audio. It uses FFmpeg.wasm and Remotion for client-side timeline rendering without uploading user media to external servers. Users bring their own API keys from fal.ai or Runware to generate content directly inside the app.
