It's a set of Automator workflows for text manipulation in OS X apps https://github.com/vmdanilov/TextFlow. It had a warm welcome on HN https://news.ycombinator.com/item?id=9585115. Since that time it collected 486 stars on Github.
Happy to know that people still find it useful.
BTW, donations don't work for projects this small. But that was rather an experiment to prove what I've heard.
