I've published 3 books using a different writing tool each time and here's what actually mattered for getting the book out the door versus what was just procrastination in disguise
practical take on writing tools from someone who's shipped books in them because most comparisons are written by people who tested the free trial and never finished a manuscript
book 1: google docs wrote the whole thing in one massive document, no organization, just scrolled for days, lost scenes I'd written and accidentally contradicted myself because I couldn't find my own notes, the editing process was a nightmare because I had zero structural overview.
the book still got published and still sells, the tool didn't stop me from finishing
book 2: scrivener, the binder gave me the structural overview I was missing and the compile feature saved genuine time when formatting for publishing, those two things were worth the purchase price, but I also spent significantly more time on "organization" and the book took longer to write despite being shorter, for me personally the organizational tools were a net negative on speed even though they were individually useful.
book 3: mythrilio , the writing experience was simpler and the notes lived alongside the manuscript which worked for me, but I genuinely miss scrivener's compile feature, nothing else exports as cleanly for publishing and I ended up formatting in vellum anyway which added a step that scrivener would have eliminated.
honestly if I had to pick just one thing that mattered for actually finishing and publishing all three books it wasn't the tool it was having a daily word count target and hitting it regardless of whether my writing app was fancy or basic, I know people who've published 10+ books in google docs and people who've published nothing in scrivener and the difference is never the software
what actually mattered across all three was being able to see chapter structure at a glance and having notes accessible without switching apps
what didn't matter at all**:** graph views, linked databases, second brain systems, mobile apps I told myself I'd use and never did, dark mode (I know)
what did you write your published books in and would you switch for the next one or are you staying put
