tsquare for Obsidian

Draw UI wireframes in your notes with tsquare, a small text language for wireframe boards: screens side by side, notes, flow arrows, in clean grayscale. It's easy for AI models to write, so you can paste in what one wrote and see it right away.

Use it

Write a tsquare code block in any note:

```tsquare
board "Sign in"
  screen phone "Sign in"
    stack gap=12 padding=24
      text lg bold "Welcome back"
      input "Email" placeholder="you@example.com"
      input password "Password"
      button primary "Sign in" fullWidth
```

In reading view and live preview, the block shows the board, sized to fit the note. In live preview, like any code block, it shows its text while the cursor is inside it: click outside the block (or press Cmd/Ctrl+E for reading view) to see the board again. Select the board (or its expand button) to open it full size: zoom with the buttons, a pinch or Ctrl/Cmd + scroll, drag to pan, and select a screen's name to zoom to it. Keys in that view: + and - zoom, 0 fits the board, Esc closes it.

If the text has a mistake, the block lists each problem with its line number, with a "did you mean" when there's a close match.

The docs cover the language and every component; the playground has examples to start from.

Privacy

Wireframes are drawn on your device, by the tsquare library bundled into the plugin. The plugin makes no network requests and collects nothing.
