Features
Powerful AI file organization without compromising your privacy.
The AI model downloads once and runs entirely on your Mac using Apple Silicon's Neural Engine. Your file names, contents, and metadata never leave your device. Not even we can see them. Smart categorization recognizes photos, documents, videos, music, archives, and more — understanding context from filenames and content.
Cluster creates organized subfolders within your selected folder — perfect for cleaning up Downloads. Constellation distributes files to your Mac's native folders like Documents, Pictures, and Music. Pick the mode that matches how you think about your files.
Every change is reversible. Undo all changes and restore files to their original locations instantly. Cosmos always shows you what it plans to do before making any changes — review every suggestion, then apply with confidence.
Adaptive Intelligence
Most AI tools treat every user the same. Cosmos is different. It starts smart, but becomes yours.
Every time you accept or reject a suggestion, Cosmos remembers. Reject a suggestion? It won't make that mistake again. Prefer invoices in "Billing" instead of "Finance"? It picks that up. Over time, Cosmos builds a personalized understanding of how you think about your files.
The more you use it, the more it feels like your own personal assistant — one that knows exactly where everything should go.
Privacy
Unlike cloud-based organizers, Cosmos never uploads your files or file names anywhere.
The AI model downloads once and runs locally forever.
