MarsSeed [1] filed a deletion request for scrivener [2]: Broken foreign binary from 2015; with unbuildable legacy AUR dependencies (gstreamer0.10 et al).
Upstream's latest releases support Windows and MacOS. One can run the Windows version on WINE. Free trial is available. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/scrivener/
