hostel · for Mac

A model on your own Mac keeps your books

Version 0.2, build 202609271220, 27 September 2026. Free.

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.

What you need

Installing

  1. Download the zip and open it.
  2. Drag hostel to Applications.
  3. Open it. Gatekeeper names the developer as Crankk Inc; that is the company the app is signed and notarized under.
  4. On the first run the app asks for Ollama, then downloads the model itself and shows how far along it is.

What it does

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.
