There's a page[1] detailing how to get get the .deb file without apt, and then use dpkg for arch [2] to install it if you wanted to. Of course you'd have to manually update, and pacman won't know about it.

EDIT: Turns out there is an AUR package already: https://aur.archlinux.org/packages/typora/

Good catch.

Serves me right for just googling for "aur typora".
