Show HN: Sifty – Windows cleanup CLI/TUI with local-only AI Sifty, a new free and open-source Windows cleanup tool, has been released that offers a scriptable CLI and full-screen TUI for junk cleaning, disk analysis, duplicate finding, app management, and developer artifact pruning. The tool features a local-only AI assistant powered by Ollama that analyzes file metadata without sending data off-device, and includes safety measures such as dry-run defaults, Recycle Bin-only deletions, protected system paths, and a full audit log. Clean junk, analyze disks, find duplicates, manage apps and startup programs, apply updates, prune dev artifacts and git worktrees, and organize files — from a scriptable CLI or a full-screen terminal UI. The optional AI assistant runs locally via Ollama https://ollama.com : nothing leaves your machine, and it only ever sees file metadata names, sizes, paths , never file contents. Sifty deletes files and changes system state, so it is built to be hard to misuse: Dry-run by default — every destructive command previews what it would do. Real changes need an explicit --apply . Recycle Bin, never permanent delete — all removals go through one trash function backed by Send2Trash. sifty undo restores the last clean. Protected paths — C:\Windows , Program Files , ProgramData , the drive root and your profile root are refused even with --apply --yes . Audit log — every applied deletion is recorded in %APPDATA%\sifty\audit.log . The AI never deletes anything — it is advisory; high-risk tool calls always require your approval. | Feature | Sifty | CCleaner | Revo Uninstaller | WinDirStat | |---|---|---|---|---| | Junk / cache cleaning | ✅ 11+ categories | ✅ | ➖ | ❌ | | Disk usage analysis | ✅ top-N + volumes | ➖ | ❌ | ✅ treemap | | Duplicate finder | ✅ SHA-256, NTFS-aware | ✅ paid | ❌ | ❌ | | App uninstall + leftover scan | ✅ winget + leftovers | ✅ | ✅ + leftovers | ❌ | | App updates | ✅ via winget | ✅ paid | ❌ | ❌ | | Startup manager | ✅ reversible | ✅ | ✅ | ❌ | | Dev artifact purge node modules, … | ✅ | ❌ | ❌ | ❌ | | Git worktree / WSL2 VHD cleanup | ✅ | ❌ | ❌ | ❌ | | Local AI assistant | ✅ Ollama | ❌ | ❌ | ❌ | | Scriptable JSON output | ✅ | ❌ | ❌ | ❌ | | Recycle Bin + undo for everything | ✅ | ➖ | ➖ | n/a | | Price | Free, MIT | Freemium | Freemium | Free | Sifty is built developer-first : everything is scriptable, the engine is a reusable Python library, and it cleans the things developer machines actually accumulate build artifacts, orphaned worktrees, bloated WSL2 disks . pipx install sifty recommended isolated ; or: pip install sifty scoop bucket add sifty https://github.com/Vortrix5/scoop-bucket; scoop install sifty winget install Vortrix5.Sifty once the winget-pkgs PR is merged sifty doctor check admin rights, winget, Ollama Prefer no Python install?
