  1. 01

    Simple

    What you look for is where you expect it. Open it and work: nothing to set up before you start.

  2. 02

    Flexible

    Keyboard or mouse, light or dark, French or English; Claude, or an AI running on your own computer.

  3. 03

    Powerful

    Everything from the keyboard, several windows, large volumes without slowing down.

  4. 04

    Smart

    An assistant that knows what is in front of you, proposes, explains, and leaves the decision to you.

Pupitre Hub, at the centre

One app that sums it up, five apps that talk to it.

Pupitre Hub gathers what the other apps and your work tools tell it, and every morning sums up your day: what needs your attention, wherever it comes from.

And your AI agents plug into it too: they read what Pupitre knows, and never act in your place.

The pencil case

Six tools, one family.

Ardoise, Craie, Cahier, Plume, Calepin and Pupitre are French for the slate, the chalk, the notebook, the quill, the pocket notebook and the school desk: each app is named after something from the schoolroom, and Trousse is the pencil case that holds them.

What sets them apart

Built to last, not to lock you in.

  • Fast and light

    Real apps for your computer: they open in an instant, stay light and follow its ways (menus, shortcuts, windows).

  • One family

    The same gestures, everything from the keyboard, the same settings, the same assistant: know one and you are at home in the others. And Pupitre Hub brings them together.

  • An AI that proposes

    The query, the fix, the message or the reply arrives as a proposal to review. Nothing runs, is written or is sent without your say-so.

  • The AI you choose

    Claude, with your subscription or your key, or an AI running on your computer, free and private: Apple’s on recent Macs, or another one you install.

  • Your passwords protected

    They go into the system’s vault (the Keychain on a Mac, its counterpart on Windows or Linux), never into a file.

  • Dictation, even offline

    Speak and the text appears as you talk; the audio never leaves your computer. In Ardoise DB and Craie Text.

  • Open to your AI agents

    Your AI agents can look at your databases and your day without seeing your passwords; what they propose waits for your approval.

  • Mac first, everywhere next

    Designed on the Mac, and the same apps on Windows and Linux.

The assistant

The AI proposes. You decide.

The family’s assistant reads what is in front of you (your data, your text, your changes, your mail) and answers with a proposal: a change to accept or reject, a reply to read before you send it. It never has more power than you.

  • Off by default Nothing leaves until you turn it on, and you see what is sent.
  • It reads, it touches nothing Its tools only read; a change becomes a proposal that waits for you.
  • No server in between The apps have no server of their own: your text goes to the AI you chose, or nowhere.

Your choice of AI

  • Claudeyour subscription or your key
  • Apple’s AIon your Mac, free
  • Ollama, LM Studioon your computer
Keeps the cities with at least 10 orders, busiest first.

Privacy

Your data stays with you.

No account, no tracking, no cookies, in the apps or on this site. Your passwords stay in the system’s vault; your data, files and mail stay on your computer or go straight to your own servers.

What leaves, and to whom

Systems

Mac first. Windows and Linux next.

  • macOS

    Where it all starts: Touch ID, the Keychain, the menu bar, Apple’s on-device AI.

  • Windows

    The same apps, tried on Windows, with Ctrl in place of ⌘.

  • Linux

    The same apps, tried on Linux.

Soon in your pencil case.
