Image MetaHub is a local-first Electron desktop application for organizing, browsing, and re-generating AI-generated images. It indexes media files in place (no uploads, no moving files) and extracts structured metadata — prompts, models, LoRAs, samplers, seeds, workflows — from 15+ generators including ComfyUI, A1111, InvokeAI, Midjourney, DALL-E, Fooocus, and Adobe Firefly (via C2PA/JUMBF/CBOR parsing). Beyond images it handles video, audio, and 3D model metadata. The app provides tagging, collections, automation rules, ratings, analytics, image comparison with pixel-level diffing, lineage/provenance tracking, and integration with local ComfyUI/A1111 instances for re-generation and upscaling. Pro features (visual search, clustering, batch export) are gated by an offline license system with a 7-day trial and Stripe billing.
