- SCM (Screen Memories) is a new local-first, open-source macOS tool that performs deep semantic AI searches on your local photos and videos.
- The app runs entirely offline, utilizing local models like CLIP, Whisper, and Tesseract to analyze visual frames, OCR text, and spoken dialogue.
- It directly addresses growing user privacy concerns regarding cloud-based AI scanning tools, offering a completely self-hosted, gatekeeper-free experience.
The internet’s growing anxiety over cloud-based AI surveillance has sparked a massive counter-movement in open-source developer communities. The latest viral hit taking Hacker News and GitHub by storm is SCM (Screen Memories), a local-first, privacy-centric search tool designed specifically for macOS. Unlike mainstream alternatives that upload your personal media to remote servers, SCM brings deep AI-driven indexing directly to your Apple Silicon Mac, allowing you to search every single photo and video frame offline.
Created by developer allenv0, SCM leverages lightweight, highly efficient local models to parse through folders on your hard drive. Once initialized, the app doesn’t require an internet connection, a subscription, or even an account. By running everything on-device, it offers Mac users a powerful way to locate specific memories using natural language—all without sacrificing their personal privacy to corporate cloud servers.
How It Works: Five Local Search Modes
What sets SCM apart from standard search utilities is its multi-layered approach to indexing. It features five distinct search modes: semantic visual search (via a local CLIP model), precise video scene segmentation that points to exact timecodes, optical character recognition (OCR) powered by Tesseract in over 35 languages, and exact spoken-line detection inside video files utilizing Whisper. Users can even opt-in to a local LLM chat interface that queries the extracted metadata.
For power users and privacy advocates, SCM represents a shift toward ‘local-first’ software engineering. Available via Homebrew for macOS 12+ on Apple Silicon, the project has quickly gained traction, racking up hundreds of GitHub stars in a matter of days. As tech giants continue to push for mandatory cloud integration, lightweight, user-trusted tools like SCM are proving that the future of personal computing might just be completely offline.
