Sift the junk from the keep.
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: nothing leaves your machine, and it only ever sees file metadata (names, sizes, paths), never file contents.
Safety first
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, andsifty undorestores 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.

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).
Install
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? Download the standalone sifty.exe from the
latest release.

Some operations (Windows temp, update cache, certain uninstalls) need an
Administrator terminal. sifty doctor tells you if you're elevated, and
sifty --admin <cmd> relaunches elevated via UAC.
The TUI
sifty tui opens a full-screen app with a seven-section sidebar (Home,
Clean, Disk, Apps, Monitor, Reports, AI):
- Home: volume gauges and a Run checkup button that scans everything at once; findings come with buttons that fix them right there (clean junk, clean stale downloads, apply updates, each behind a confirm).
- Clean: Junk / Purge / Optimize / Smart cleanup under one roof (tabs).
- Apps: Installed / Updates / Startup / Services, with fuzzy filter, sorting, bulk uninstall, and an automatic leftover scan after uninstalling.
- AI: an agentic chat where proposed tool runs show Run/Skip buttons inline in the conversation, and scan results carry follow-up action buttons.
Press Ctrl+P for the command palette (jump to any screen), F2 to elevate, Space to mark rows for bulk actions. The Reports screen shows space reclaimed over time with an Undo last clean button.
AI setup (optional)
- Install Ollama and start it.
- Pull the configured model:
ollama pull qwen2.5:3b. sifty ai statusshould report "running".
Configure everything with the sifty config command, no need to hand-edit
files:
sifty config # show all settings + your overrides sifty config set ai.model "llama3.2:3b" # use a different local model sifty config set ai.host "http://localhost:11434" sifty config set safety.extra_protected_paths '["D:\\Important"]' sifty config set junk.include_downloads_installers true sifty config edit # or open config.toml in your editor
Settings live in %APPDATA%\sifty\config.toml; sifty config set only writes
the keys you change, so defaults keep flowing through on upgrades.
Architecture
Layered: thin frontends over a reusable engine, OS specifics quarantined:
src/sifty/
├── cli/ # Typer entry point + one thin command module per group
├── tui/ # Textual full-screen app (views call core, not cli)
├── core/ # the engine: junk, disk, apps, updates, cleanup,
│ │ # startup, services, organize, checkup, history, …
│ └── safety.py # ★ protected paths, dry-run guard, trash(), audit log
├── windows/ # OS primitives: winget, registry, UAC, Recycle Bin, DISM
├── ai/ # Ollama client, advisor prompts, agentic tool loop
└── infra/ # TOML config + rotating diagnostics log
Frontends depend on core; core depends on windows/infra; nothing
imports upward. A GUI could call the same engine functions (junk.scan,
disk.find_duplicates, checkup.run_checkup) without a rewrite. See
docs/ARCHITECTURE.md for the design rationale.
Tests
.\.venv\Scripts\python.exe -m pytest -q # 160+ tests, ~20 s
The safety guardrails are the most heavily tested code in the repo; the Windows environment is mocked so the suite also runs on CI. See CONTRIBUTING.md to get involved.
