Toolbox / Principles

How these tools are built

  1. 01

    Local-first

    Every tool runs entirely in your browser. Input never leaves your device — no uploads, no server round-trips, no analytics on your data.

  2. 02

    Small and focused

    Each tool does one job well, with sensible defaults and a sample input so you can see what it does immediately.

  3. 03

    Shared contracts

    Tools are built from the same input, output and copy/download primitives, so they feel consistent and can hand results to one another with “Continue with”.

  4. 04

    Accessible

    Keyboard-friendly navigation (⌘K search), proper labels, and light and dark themes.
