I would add MonoclesChat as well, it's a fork of Conversations with some quality of life improvements. It's obviously thought to be used with the Monocles ecosystem, but works fine with whatever XMPP server ;)

I'm using Joplin and I'm quite happy with it :)

I couldn't see anyone mentioning so I would add Disco Elysium

Not your typical RPG by any measure, but one of my top favorite games of all time, more focused on exploration and talking/decisions rather than fighting. Also has a unique mechanic where "stats" are connected to mental attributes that talk with the character by offering advice, insight, or just poor suggestions depending on your level :D
