Neu is a simple application that makes it easier to create new documents in the Finder, without you having to open an application first.
It does this by adding "Create Document..." and "Create And Open Document..." menus to various places, including the main menubar, the Dock, and the Services menu that the Finder shows when you right-click on something. You can also trigger Neu from any application using a special key combination.
Neu lets you choose what to make from a list of templates, which are simply existing files. Once you've chosen a template, Neu creates a copy of it, brings the Finder to the front, and selects the new file.
Neu comes with some pre-defined templates, but you can add your own, so you can customise the types of new file available to suit your needs. It can make a blank text file, an empty letter, a shopping list, or anything else that you want. You can have one template, or a hundred - it's up to you.
