See where the character
actually changes.

On a track, it looks like a long empty stretch, and that visual is the most useful thing a tracker gives you. Concretely, a stalled arc is a character who appears in scenes but stops changing in them, most often because the story has started using them for function rather than for development: the mentor who becomes an information delivery system, the friend who exists to ask clarifying questions. Readers experience this as a character fading rather than as a specific fault, which is why it is so easy to miss while writing. The other pattern worth watching for is an arc that resolves too early, where the break happens at forty percent and everything after it is the character being consistent, which reads as flat.

Not during early access. Storyflow is paid-only right now, with plans starting at $9.99 a month, and a Free plan launches before the end of 2026. Anyone a paid member invites to a board joins free today, so a critique partner or co-author can work on the board without paying. If you want a free approach this minute, index cards on a table work genuinely well for this, since the method matters far more than the medium and the tracks are easy to lay out physically.

The want is what the character is consciously pursuing and would tell you about if asked. The need is what the story says they actually require in order to change, which they usually cannot see and often actively resist. The gap between the two is where most arc tension comes from, because the plot can then be constructed so that pursuing the want repeatedly fails to deliver the need. It is worth writing both on the board explicitly, because arcs where the want and the need turn out to be the same thing tend to have nowhere to go: the character gets what they were chasing and nothing internal has been tested.

Give every character a track, including the ones you suspect do not have an arc, because finding that out is the point. There is no object cap, so a cast of twenty each with their own track fits on one board without splitting into files. What usually emerges is clarifying rather than discouraging: three or four characters have real arcs, several have a single turn, and the rest are functionally scenery. That is often correct for the book, and knowing it explicitly lets you decide whether a character deserves an arc or deserves to be cut, instead of leaving them in a middle state where they take up space without developing.

It can build the structure and spot patterns, and it should not decide the change. Describe the story and the AI lays out the plot spine with arc tracks ready to fill, reading the active canvas as context so it works with what you have already placed. Once the board exists it can point out arcs with long empty stretches or arcs that resolve unusually early, which is a genuinely useful structural observation. What it cannot do is decide what your character should believe or how they should change, because that judgment is most of what makes a book worth reading. Storyflow is a planning canvas rather than a prose generator.

Yes, and this is the most common and probably the most valuable use. Card out the draft you have, one card per scene, then mark on each character's track the scenes where they genuinely change. The arcs you have actually written become visible, which is frequently different from the arcs you intended, and the difference is usually the reason a draft feels off without an obvious cause. Doing this before a revision pass is far more efficient than rereading, because rereading is the wrong instrument for seeing a shape.

No, and believing otherwise leads to bloated manuscripts. Plenty of characters exist to apply pressure, provide contrast, or perform a function, and giving each of them a change of belief dilutes the ones that matter. What is worth avoiding is the middle state, where a character takes up significant page time and half-develops without either arc or clear function. A tracker makes that state visible: their track has two cards, widely spaced, and neither leads anywhere. At that point you can commit to the arc or commit to the function, and either decision improves the book.

Yes. Share a view-only link and a critique partner, agent, or developmental editor opens the whole board in a browser with no account. The specific benefit is that it changes the kind of feedback you get: a reader looking at arc tracks responds to structure, whereas a reader handed three chapters responds to prose. For a developmental edit in particular, the arc board is often more informative than the opening fifty pages. You can also export it as an image or PDF to mark up.

Yes, and they belong together. The arc tracks run underneath the plot spine, subplot tracks run alongside them, and character profiles can be pinned beside the arcs they drive. That arrangement is what lets you see that a subplot and an arc are meant to resolve in the same scene, or that a character's break has been scheduled for a chapter where they do not appear, which are exactly the collisions that are invisible in a linear document.
