Writing is a creative work. While Microsoft Word and Apple Pages are popular and handy, they tend to provide lots of features on formatting, but neglect the need of creative writing. eWriter is a tool focusing on pure writing with proper support to modern formats, like markdown files, source code, etc. We have laid out rich features to support technical writing, fiction writing, etc. Give it a try, or keep an eye on what it offers that might fit your needs.
It is smaller and faster to download, and occupies less space. eWriter doesn't pack with any dictionaries. It uses system's word list instead. Mac OSX has a word list at
/usr/share/dict/words. That is the dictionary eWriter uses. It contains about 235,000 to 236,000 entries. That is a lot of words. We will definitely add features into eWriter. But it will be kept at the same size or smaller.
All in all, enjoy eWriter, and please do try Numathic Write if you want to commit to writing.
