hostel is a Mac app where a model running on your own machine keeps your books through Saybooks, on the Mac or on saybooks.io.
Your data stays on this Mac: the books, the documents, and what you type or attach. The model runs here too, so what it reads and writes stays here as well.
The one thing that goes out is a web search, if you turn it on, and the app says the same about that switch: the model's search queries and the pages it reads go out to the internet; your books, your files and what you type do not.
Say what happened and the model records it in Saybooks: invoices, orders, a job hunt, your own spending from a statement. The rules live in Saybooks, so a wrong entry is refused whichever model is typing, and every act is on a record you can read. The books can be a space on this Mac, or one on saybooks.io by sign-in; each conversation carries its own connection.
