SupaDupa is a macOS menu bar app that helps you make sense of messy storage: old external drives, an overflowing Downloads folder, a decade of camera dumps. It scans a folder, finds exact duplicates with a BLAKE3 pipeline, surfaces near-duplicate and visually similar images, and renames files based on what's actually in them. It's for Mac users with cluttered disks who want to reclaim space and get organized without uploading anything to a cloud.
The intelligence runs on-device. SupaDupa uses Apple's Vision framework to classify image contents, read text inside screenshots, and compute feature-print embeddings that catch edited or re-exported copies a plain hash would miss. Nothing leaves your machine. There's no server, no account needed to scan, and no large language model in the loop. The trade is deliberate: local-first and private by default.
SupaDupa is live at version 0.3.3, with a free tier and a Pro upgrade. Right now I'm landing content-aware organization, including crash-safe file moves. Download or follow along at supadupa.tech.
