cowyo.com

TLDR: Open cowyo.com, type on a blank page, and share its URL. The page saves automatically and can also be read or written as plain text with curl. I first made cowyo in 2016 as a fast, self-contained place to jot down notes. Over time it became a small wiki, with Markdown rendering, history, lists, locks, encryption, and other modes. For version 3 I went back to the original idea: a pastebin for minimalists.
