Meet the apps Download

macOS first · Windows and Linux next, from the same code

  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 a model on your own computer.

  3. 03

    Powerful

    Shortcuts everywhere, a command palette, 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.

The pencil case

Four tools, one family.

Ardoise, Craie, Cahier and Plume are French for the slate, the chalk, the notebook and the quill: each app is named after a school tool, and Trousse is the pencil case that holds them.

What sets them apart

Built to last, not to lock you in.

  • Native and fast

    Real desktop apps with a Rust core: they open fast, stay light and follow the system’s ways: menus, shortcuts, windows.

  • One family

    The same gestures, a command palette everywhere, the same settings, the same assistant: know one and you are at home in the others.

  • An AI that proposes

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

  • The model you choose

    Claude with your API key or your Claude plan (through Claude Code), or models running on your computer: Apple’s on-device model on Macs with Apple Intelligence, Ollama, LM Studio.

  • Your keys in the keychain

    Passwords and API keys go into the system’s keychain (macOS Keychain, Windows Credential Manager, Secret Service on Linux), never into a file.

  • Dictation, even offline

    Speak, and the text appears as you talk. Whisper runs inside the app, and the audio never leaves your computer. In Ardoise DB and Craie Text.

  • Open to agents

    Ardoise DB is an MCP server: Claude Code and other agents explore your databases without seeing your passwords, and their changes wait for your approval.

  • macOS first, everywhere next

    Designed on the Mac, built from the same code for Windows and Linux.

The assistant

The AI proposes. You decide.

The family’s assistant reads what is in front of you (the schema, the file, the diff, the thread) and answers with a proposal: a diff to accept or reject, a query to read before you run 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 provider you chose, or nowhere.

Privacy

Your data stays with you.

No account, no telemetry, no cookies, in the apps or on this site. Your passwords stay in the system’s keychain; your databases, files and mail stay on your machine or go straight to your own servers.

What leaves, and to whom

Systems

macOS first. Windows and Linux, from the same code.

  • macOS

    The reference platform: Touch ID, the Keychain, the menu bar, Apple’s model.

  • Windows

    The same code, built and tested for Windows, with Ctrl in place of ⌘.

  • Linux

    The same code, built and tested for Linux.

Soon in your pencil case.
