About

possiblymadebyahuman records the editing process of a piece of writing, signs it with a hash chain, and gives the author a short URL anyone can check. It works through a Chrome extension for comments, forum replies and email, a web writing page, or Emacs. It does not detect AI text or prove human authorship; server timestamps make a long writing span costly to fake, which supports the author's claim.
