How to sketch and create protoypes of your ideas

Dr Android ROM

pencil project designOne of the most important work done by engineers, developers, marketing managers and others is to turn their ideas into reality. One of the procedures included in this process is the creation of sketches and prototypes.

I use traditional tools (pen ‘n paper) when it comes in designing, sketching and prototyping any ideas before I start building them. Pencil Project convinced me that my life would be easier and more “compatible” with other apps.

Pencil Project is a free and opensource tool for making diagrams and GUI prototyping that everyone can use. It is a Firefox extension that helps you to lay out and sketch your ideas using a wide range of elements, including common shapes (circles, triangles, squares etc.), GUI, web elements and more. After you have completed your work you can then export it in PNG, SVG, HTML, PDF and ODT file formats to use them in other apps, for adding more features.

And much more…


Pencil Project is available for:

  • Linux
  • Mac OS
  • Windows

and the only thing you have to do is to download the extension:

After you have download it, right-click on the file Pencil-x.x.x.xpi and open it with Firefox. After the installation you will be prompted for restart of Firefox. Then you just go Tools –> Pencil Sketching on Firefox and a new window with Pencil Sketching will appear.
