Everything you need

Never lose a storyline again

Every subplot, every book, and every loose end, all on one board.

One board for every storyline

Your plot threads run across the top and your books run down the side. Each square holds the plot points for that thread in that book.

See what's still open

Tick a thread resolved when its storyline is finished. You'll see at a glance which ones still need to pay off.

Linked to your scenes and chapters

Link a plot point to a chapter, scene, or plot beat you've already planned. One click on the card takes you straight there.

Threads for your characters

Add the characters a storyline is about, and the thread shows up on each of their character pages.

Made for series

Follow a storyline from Book 1 to Book 3. Add another book to your series at any time and your threads come with it.

Your own order

Drag plot points into your own order. Give each thread a color and keep notes on what it sets up.

All in one place

A plot tracker inside your story plan

Most plot trackers are a spreadsheet or a pile of sticky notes. In Quill&Steel OS, your threads live next to your scenes, chapters, and characters.

Link a plot point to the scene where it happens. That scene then shows every thread running through it. Add characters to a thread and it appears on their pages too.

How do I keep track of subplots across a series?
