Only for Mac

Mac
AI tells you what's safe to delete — with reasons. Reclaim your Mac's storage from caches, DerivedData and node_modules. Everything runs on-device.
Soji ("cleaning" in Japanese) is a macOS disk cleaner built for developers.
"Can I delete this file?" — on-device AI answers that question, with reasons.
■ AI judges what's safe to delete
Soji scans caches and old files, rating each as Safe, Caution, or Dangerous — always with an explanation. A two-stage design rates the obvious cases instantly by rules and sends only ambiguous files to the AI, so it's both fast and accurate.
■ Ask AI when unsure
"What is this file? What happens if I delete it?" Chat right in the app. Answers consider creation date, last access, and the app the file belongs to.
■ Built for developer junk
DerivedData, node_modules, simulator caches, DeviceSupport, package caches (npm / Gradle / Cargo / Maven and more), and web build caches (.next / .turbo). Sweep away the gigabytes that development leaves behind.
■ Everyday junk too
App caches, logs, old DMG/ZIP installers, leftovers from deleted apps, iPhone backups, and your Downloads folder. Choose exactly what gets scanned.
■ Your rules win
Write "never delete this" in rules.md and it takes precedence over AI and built-in verdicts.
■ Built-in uninstaller
Move an app and all its related files — preferences, caches, logs — to the Trash together.
■ Designed for peace of mind
- Deletion only moves files to the Trash. Everything is reversible
- Scans only the folders you explicitly allow
- AI runs entirely on-device. Your file info never leaves your Mac
- Zero data collection, zero network access
Requires macOS 26 or later. AI assessment is enabled on Apple Intelligence-capable Macs; otherwise Soji runs with rule-based assessment.
