Features
Recall.
Ask about anything you have read or opened. Local, encrypted, searchable.
Your own history, on your Mac
Melvin keeps a local index of pages, documents, and app activity so you can ask in plain language later. It lives on your Mac in an encrypted store. Nothing is uploaded for this, and it works before you sign in.
Search is always available. Asking Melvin to answer from that history is part of the product, not a separate install.
