I use tools like Google Keep and Evernote from time to time to manage my pile of recipies, data and "knowledge" (what ever that'd be ;)). However, I don't feel really comfortable and looked for alternatives. There are certain plugins for ownCloud, however, these are basically text-editors at best... Never liked that idea. So I came around Paperwork: http://paperwork.rocks/.
Truth beeing told: It is still in development. It is as bleeding edge as it gets. Sharp as a knife. And yes - I forgot to do backups of my (until then not used) database and lost a lot of data on an simple update... (Yep, the reason why I introduced you to automysqlbackup some days ago...).
But at the moment, it is working very well and I like it very much. I think it will become an really great tool :)!
