How to disable automatic identation - eviltoast

I’m normally a straight vim user (just out of habit, no particular preference) and I’m giving neovim a spin. So far I like it but…

For the love of all that’s holy, how do I disable automatic indentation?

I have noautoindent set, nosmartindent set, filetype indent off, but neovim keeps inserting indentations. The only thing that works is setting paste on, but that’s not the right solution to this problem.

Please help. This is driving me nuts!
