This service should not cost more than 3 dollars a month, for example most of my previously Evernoted friends used to migrate to Telegram free storage. Maybe Telegram provides only mediafile storage with no advanced search - but the search algorythm among your text document should not be significantly costier than GNU Emacs in Org-mode.

Stepan Pachikov is so great guy, I listened a lot of his talks. I am sad to live without his software, without screenshot editing software having red arrows of some specific form and without the search which worked really well. Good-bye yet another greedy corporation.
