I now use Longform in Obsidian for my novel writing after migrating away from “traditional” writing software like Scrivener. I’m only in this sub due to keeping an eye on what similar apps are doing, but I have never used Logseq and only use Obsidian.
I write grimdark science fantasy with a fantasy emphasis. My world has a 3000 year history currently that the series I am working on is in the middle of. Not to mention, I track lore items, characters, locations, tech, etc all in Obsidian. I could never do this in Scrivener without it turning into a mess. I also used Notion before Obsidian but found it was too structured for me.
That being said, I’d highly recommend any program like Logseq for planning, as others mentioned.
Longform in Obsidian (and any feature Logseq may have to compile and strip markdown) works great for exporting to editing or collaboration tools.
I rarely use the linking offered in Obsidian while actively writing. But it’s very useful when I’m editing.
all that being said, if your wife is used to writing in scrivener and the features it offers for that, using something like Logseq for planning and editing makes sense and is borderline mandatory for complex series .
I’d recommend she starts with planning and editing in Logseq or something similar and if she finds the workflow makes more sense to cut out scrivener like I did, then she can go for it. But for actually getting words on paper/screen, it’s important (at least for me) to minimize any friction. I need access on mobile, desktop, etc and the ability to just start putting down words.
