Sketch a screen in plain text.
Stamp parts on a grid. Copy it anywhere.
$0.99 on the App Store. Free on the web.
This is the real app. Pick a part, click the grid, drag it around, then export the text.
What it does
A wireframe you can paste.
Every other wireframe tool hands you a picture. Blockprint hands you text, so it lives in the same place as your code.
[ OK ] [____] [x] a (o) b
23 parts
Buttons, inputs, tables, modals, navbars, tabs and more. Stamp them as characters, not pixels.

Move, resize, edit
Drag a part, nudge it with the arrow keys, double-click to change its words. Duplicate and reorder in a key press.
``` ┌──────┐ │ Hi │ └──────┘ ```
