Plot outlines
Structure your story with the Hero's Journey. On the Story Planner plan, you also get the Save the Cat! beat sheet and the Snowflake Method.
Scenes and chapters
Give each one a point of view, purpose, status, cast and setting, with room to summarize or draft.
Manuscript editor
Write your draft in the app, or import an existing manuscript from DOCX. Export to DOCX, ePub or PDF whenever you're ready.
Mentions while you write
Type @ to link a character, place or anything else in your world straight from your draft.
Writing sessions
Track your word count and writing time automatically, and see your progress across the whole draft.
Plot holes
Keep a running list of what to come back and fix, so nothing gets lost between drafts.
All in one place
Your story lives inside your world
The story planner is built into Quill&Steel OS, alongside your characters, locations, maps, magic systems, cultures, family trees, timeline and custom calendar.
Every scene and chapter links to its characters, places and plot points. Open a chapter and see who's on the page, where it happens and which beat it hits, then click straight through to any of them.
Made for worldbuilders

Yes. Import a DOCX file and keep writing in the manuscript editor.

What fantasy writers are saying...
"What an incredible platform! I have gone from 'I have an idea but no clue where to start,' to actually writing the first 4000 words, and having a pretty well-fleshed out world and magic system in place in only a week! Considering an outline for the plot has been in my head for around 7 years, I am ridiculously happy with this. I would absolutely, 100% recommend using Q&S OS!"
"This app is really cleanly made and the design is so cute! It's also incredibly well-designed and thorough when it comes to entering info about your fantasy world. Incredibly useful and fun tool for both fantasy authors and DMs."
"I love this app. The interface is really user friendly and doesn't just give you a base on which to work, but gives you advice and guidance as you go along."
