Based on my popular Live Writer plugin there is now a online version of the tool that can be accessed from anywhere.
As many people are moving away from Live Writer or Open Live Writer and using many various blog editing tools for their WordPress sites I have replicated the core functionality of my popular plugin into an online tool.
When you are writing a WordPress post in your editor of choice and want to insert a Source code snippet then just hop over to http://WPCodePreview.com and build your code snippet. Enter/paste your code and choose the various display and format options, and preview immediately how it will look. Once your happy with it – just click to copy your code and the generated Shortcode to your clipbaord and then paste it into your editor.
Its free to use, requires no user accounts and also as everything is done in your browser no data is saved by us.
