Image MetaHub is a local-first, open-source desktop app for managing AI-generated images and videos. It automatically reads generation metadata from tools such as ComfyUI, Automatic1111, Forge, Fooocus, InvokeAI, SwarmUI, SD.Next and Draw Things, making it easier to search, compare, organize and continue previous generations. Users can browse large local libraries, inspect prompts, models, LoRAs, seeds, samplers, steps and workflows, compare variations side by side, add tags and notes, preserve PNG metadata on export, and send images or prompts back into supported generation tools for further work. Image MetaHub is designed for creators who want full control of their media library without uploading files to the cloud, keeping their AI outputs, workflows and metadata private and accessible on their own machine.
