Auto-mosaic faces in videos, plus on-device AI for photos: erase objects, upscale, remove backgrounds, or edit with a prompt. Everything stays on your Mac. Free to use. MosaiClip is a video editor for Mac that automatically detects faces in videos and photos and keeps a mosaic tracking them as they move. Everything runs entirely on your Mac — your videos and photos are never uploaded anywhere. It combines privacy-aware editing with a workflow designed for AI video creation. AUTOMATIC FACE MOSAIC - Detects faces automatically and keeps a mosaic, blur, or black bar tracking each one as it moves - Toggle masking on or off for each detected person - For anything face detection can't catch (name tags, license plates, on-screen content), just circle it once and object tracking follows it from there. Lost it? Circle it again and continue - Choose from three masking styles: mosaic, blur, or black fill. You can also drag a rectangle or draw freehand to set the area BUILT FOR AI VIDEO WORKFLOWS - Repeat any section as many times as you like — handy for looping short AI-generated clips into a video of the length you need - Export the final frame as a PNG automatically alongside your video. Use it as the source image for the next generation in image-to-video workflows such as ComfyUI - Trim unwanted parts and add text or effects AI EDITING FOR STILL IMAGES - Eraser: remove people or objects you outline — the area is redrawn naturally from its surroundings - Upscale images to 2× or 4× resolution - Background: recognizes people and subjects, then makes the background transparent, blurred, or white - Edit with a prompt: redraw the whole image or a selected area with instructions like “make it a snowy scene” — in your own language, too - Create images with AI: generate a new image from a description, then edit it as a photo or add it to the start or end of a video as a still shot (title screen or end card) - Download only the AI models you need, free, right inside the app. All processing runs on your Mac EXPORT - Choose H.264 or HEVC (H.265), quality (high / medium / low), and resolution - Set a default destination folder once and skip the save dialog on every export PRIVACY - Face detection, tracking, and export all happen on your Mac. Nothing is sent to any server - The app connects to the model distributor (Hugging Face) only to download AI models. Your images and prompts are never sent - No account required PRICING - Free, with no limits on length, resolution, or features (exports carry a small logo in the corner) - A one-time purchase removes the logo. No subscription, no recurring charges - Purchase restore is supported Great for: - Hiding the faces of passers-by or children before sharing videos on social media or at work - Interviews, street footage, and event videos - Editing AI-generated videos, building loops, and grabbing the last frame for your next generation
