I am a big fan of Joplin, I have been using it for 1 month now, and my notes are currently synced with object storage in Alibaba Cloud.
I hope that Joplin can truly become a copywriting tool for video content creators, and the Chinese market is an integral part of it, and I hope to add a Chinese grammar check for Chinese users, while valuing the experience of Chinese users accessing Joplin's cloud sync service.
unfortunately you need to find a people understand there clooud services you mentioned, maybe relying on files system is easier.
