Sifty is an open-source Windows 10/11 maintenance tool designed to safely clean junk files, find duplicates, manage apps and services, and purge developer clutter. It enforces safety by funneling all deletions through a single function that sends files to the Recycle Bin (never permanently deleting), uses strict path protections to prevent critical system deletions, and defaults to dry-run mode to avoid accidental data loss. An optional AI assistant runs locally via Ollama, only accessing metadata (file names, sizes, paths) to advise users without reading file contents or performing any deletions. The AI suggests actions but requires explicit user approval for all operations. This approach balances effective cleaning with strong safeguards against accidental or malicious file loss.
