Playscii is a powerful, open-source ASCII-based art, animation, and game creation tool. Advanced layer-based tools and import and export options are available through a familiar window system with the appeal of classic DOS development tools like QBasic.
Monodraw allows you to easily create text-based art (like diagrams, layouts, flow charts) and visually represent algorithms, data structures, binary formats and more. Because it's all just text, it can be easily embedded almost anywhere.
JavE (Java Ascii Versatile Editor) is a free Ascii Editor. Rather than for editing texts, it is intended for drawing simple diagrams by using Ascii characters. It is like a graphics editor for editing texts instead of images.
