DuoBolt is a desktop application for macOS and Windows. It finds exact duplicate files by full BLAKE3 hashing, and groups look-alike photos with a separate engine that ranks them and explains the pick. All inference runs on the device; nothing is uploaded and no account is required. DuoBolt prioritizes safety, performance, and clarity with a local-first architecture where all processing happens on your machine. The workflow is review-first, fully auditable, and reversible.

DuoBolt finds and cleans duplicate files with a fast, modern engine. It scans large folders, codebases, design projects, and NAS volumes with high accuracy and low overhead. The desktop app runs on macOS and Windows; a free CLI is included for macOS, Windows, and Linux. DuoBolt uses BLAKE3 for multi-threaded hashing and delivers clear, visual results without unnecessary clutter.
