48pages

48pages is a computer software listed on Trustburn. 48pages is a digital notebook application that limits each notebook to 48 pages, modeled after the size of a Field Notes memo book. The service offers end-to-end encryption and explicitly does not include AI features or tracking.

The app is currently available through an invitation-only private beta, meaning new notebooks are invitation-only right now. Users can request an invite to join the waitlist. The service is designed for people who want a notebook that ends with a conscience, where every scrap has to earn its ink because the page can't grow forever.

The core concept is that a page that can't grow forever can't turn into a bottomless pile you never revisit. When the page fills, you archive it and start the next one sequentially. This limit is the whole idea, ensuring that holding less is the point of the tool.

The app features four verbs for managing scraps: roll them into tasks, file them into a searchable cabinet, gather them by hashtag, or scratch them out. A fifth verb, ferry, carries an idea out of 48pages to TheSlot or Endpaper to grow into an outline or published piece. Each action leaves a visible scar on the original page so the record is never lost.

The platform is built natively for Mac, iPad, and iOS, with web access available today. Native apps are in active development. Everything you write is end-to-end encrypted on your device before it syncs, using a key derived from your recovery phrase that the developer never receives.

The service is currently free while in private beta, with no trial, no countdown, and no feature switched off until payment. The full notebook, on a single device, includes the entire writing experience, the 48-page limit, all four verbs, the cabinet, and the shelf ceremony. The price for Plus tier is TBD, but it will cover encrypted sync across devices and unbounded cabinet limits.

The app works entirely offline first, with sync being opportunistic. You can write on a plane or in a basement without a signal, and it catches up when you are back online. Your notebook is never hostage to a connection, and the page lives on your device before any sync occurs.

To export your writing, you can always get your writing out as plain markdown any time on any tier. The entire page, the cabinet, and every shelved book are available for export. There is no lock-in of any kind, making leaving as easy as arriving.

The app is described as a small private beta with a one-person team building under the name Tidyapps. Aaron, the creator, builds the software on nights and weekends around a day job and a family. The site explicitly states it is a one-person operation with no team, no investors, and no growth chart deciding what it becomes next.

The app uses a zero-knowledge architecture where encryption happens on your device with a key derived from your recovery phrase. The developer stores ciphertext and salts but holds no key that opens them. Even if compelled, there is nothing on the servers to read, and the recovery phrase is the only key.

When a notebook reaches page 48, it shows you the ledger of days, scraps, and actions taken. It asks whether you are ready to shelve it and open Book No. 2. Nothing is deleted; the finished book goes to your shelf, read-only and always openable.

The app allows only one notebook to be open at a time, enforcing sequential volumes rather than parallel ones. This ensures the limit means something and keeps the product focused on keeping only what is worth keeping. You archive the current book and start the next one.

The service includes a feature called Ferry that carries an idea out of 48pages to external tools. It connects to TheSlot to grow an idea into an outline or to Endpaper to write the real piece. The page keeps a ferried scar so it remembers where the idea went.

The app is designed for users who want a notebook that ends with a conscience, where every scrap has to earn its ink. It suits those who prefer a page that stays honest and end-to-end encrypted sync that keeps it theirs across devices. The service is for people who value a small, private notebook over a bottomless pile.
