QwikiTXT is a mini project we released lately. You can read about the “why” here. It’s an online notepad, which you can use immediately, without the need to sign up or anything.
You can use it to collaborate with others on a text or note something down for yourself. Besides that QwikiTXT has two special features, it remembers 10 previous versions of the text and it can visually show the changes between the versions. Both of these features are generally nice to have, but come specially handy when collaboration on text with others.
Here is a simple screen cast to quickly show the QwikiTXT work flow:
