Real tools that run in your browser tab.

A CAD editor that opens native DWG, a 3D modeller with a slicer, and a sample workbench that splits drums into stems. Your files never leave your computer.

Three tools, one tab each

What happens to your files

No install

Open the page and start. The tool is one page that runs in the tab you already have.

No upload

Your file is read by the page itself. Every result is made on your computer, and nothing is sent anywhere.

No sign-in

No account, no email, no trial. What a tool keeps between visits stays in your browser.

One set of commands

Mouse, keyboard, screen reader or agent: the same way in.

Each tool declares its commands once. The buttons, the command palette, the command line and the agent interface are all built from that list, so nothing is reachable one way and missing another.

  • Command palette

    Press Ctrl K in cicada or schmelze to find every command by name.

  • Command line

    Type L for a line in cicada, or box 40 20 10 in schmelze.

  • Screen readers

    The drawing surface has a sentence that says what is on it.

  • Agents

    The same commands, with a schema, on window.hexenwerkzeug.
