I would need a desktop editing application for a static site generator (Hugo) for non tech people. Edit happens locally, then the content folder is synced remotely (Syncthing) where build happens. https://www.pubcrank.md/ is the right idea, but not free and chrome only, and still a bit raw.
Can you suggest more similar apps?
Requirements: desktop app, single user, wysisyg, that works offline.
