Pinstamatic is a web based tool that makes non-photographic content more visually appealing on Pinterest. It allows you to post website URLs, quotes, text, Spotify tracks, Twitter handles, calendar dates, locations, and photos with captions. If you don't always have photos to share, then this is a great way to make your text based content fit into the Pinterest world better.
Pinstamatic is free and easy to use. Go to Pinstamatic.com, and choose the type of content you want to share. Enter the content, and hit "Pin" to post it to Pinterest. There's no editing tools or formatting to worry about -- it takes care of it for you.
