What is WriterDuet, and what is this instead?
WriterDuet is screenwriting software, and it is genuinely good at what it is for. It formats a screenplay correctly, it has real-time collaboration that predates most of its competitors having any, it keeps revision history and coloured pages, and it runs in a browser as well as offline. If what you need is to write and share a properly formatted script with a co-writer, WriterDuet does that well and this page is not going to pretend otherwise.
The reason people look for something else is usually that they are not stuck on the writing. They are stuck before it. The script will not come because the structure is not working, and a screenwriting application is not built for that problem. Its outlining and index card features exist, and they are attached to a document, which means they behave like a document: linear, one thing after another, and awkward the moment you want to see act two beside act three or move a beat and watch what it does to the sequence. Structure is a spatial problem and a script editor is a linear tool.
The second thing that lives badly inside a screenplay file is everything that is not the screenplay. The character work, the research, the reference images, the map of the world, the timeline of events that happen before page one, the version of act three you abandoned but might return to. All of it ends up in other files, and the connection between a scene and the research that justified it exists only in the writer's memory of the week they wrote it.
Storyflow is an AI-native infinite canvas, and it is deliberately the other half of the job rather than a replacement for the script editor. Describe the story and the AI lays out a beat board with cards across the acts. Then you do the real work: drag beats until the shape is right, run character arcs as their own rows beneath the spine, pin the reference and research beside the scene it feeds, and keep the abandoned act three in a corner of the canvas rather than in a folder you will not open. When the structure holds, you write the script in WriterDuet, Final Draft, or whatever you already use.
HOW IT WORKS
From an idea to a structure that holds.
No formatting, no page count. Cards, arcs, and the space to see the whole thing.
01
Open a canvas
Sign up in seconds. No download. Your infinite story canvas opens in the browser.
02
Describe the story
Type the premise, the character, and what changes. The AI lays out a beat board across the acts, so you start by arguing with a shape rather than staring at a blank page.
03
Move beats until the shape is right
Drag cards, run character arcs as rows beneath the spine, and mark the act breaks. A structural problem is visible as a gap or a pile long before it is visible in a draft.
04
Write the script wherever you write
Take the structure into WriterDuet, Final Draft, or anything else. Share a view-only link with a co-writer or a producer, or export the board as an image or PDF.
Beats, arcs, research, and the versions you kept.
The planning surface a script editor was never trying to be.
AI lays out a beat board from a premise
Start from a shape, not a blank page
Describe the story and the AI produces beats across three acts with the act breaks and midpoint marked. Correcting a proposed structure is far more productive than generating one from nothing.

Index cards that move in two dimensions
See act two beside act three
Cards in a document scroll. Cards on a canvas sit side by side, so a sagging middle or three beats doing the same job is something you notice rather than something a reader tells you.

Character arcs running under the spine
Track who changes, and where
Run each character as a row beneath the beat spine. A protagonist whose arc has no beat in act two, or an antagonist who disappears for forty pages, is visible as an empty stretch.

Research and reference beside the scene
Keep the material where the scene is
Interview notes, photographs, location reference, frames pulled from films you are stealing from. Pinned to the beat they inform rather than in a folder that stops being opened.
Try the story planning tool →Unlimited boards. No object cap.
Open a canvas, describe the story, and let AI lay out the beats. Storyflow is paid-only during early access, with plans from $7.99 a month billed annually, and a Free plan launches before the end of 2026.

WHAT IS DIFFERENT
This does not format screenplays, and that is deliberate.
WriterDuet is a script editor with planning attached. This is a planning canvas that hands off to a script editor.
The honest split
What you keep WriterDuet for
Screenplay formatting: Storyflow does not format a screenplay, does not paginate, and does not produce a PDF anyone would submit. If you need industry-standard formatting, you need a script editor and this is not one.
Revisions and coloured pages: Production drafts, locked pages, and revision colours are specialised features that matter enormously once a script is in production, and WriterDuet handles them properly.
Real-time co-writing on the script itself: Two people typing in the same screenplay at once is WriterDuet's signature feature and it works. Storyflow's collaboration is on the board, not on the pages.
What this adds instead: A spatial surface for structure, character arcs as visible tracks, research attached to beats, and an AI that reads the whole board. All of it before the script, and none of it in competition with the script editor.
Structure you can see rather than scroll
The frameworks, laid out rather than listed
Three act, with the breaks marked: The most useful thing about drawing the acts is proportion. An act two that occupies half the canvas and contains four beats is the sagging middle, visible before the draft that proves it.
Save the Cat and the beat sheet traditions: Templates for the standard beat structures, laid out as cards you move rather than as a list you fill in. The point of a framework is to notice where your story departs from it deliberately.
The story circle and cyclical shapes: Not every story is a line. Circular and parallel structures are painful to represent in a document and natural on a canvas.
Your own structure: Frameworks are diagnostic, not prescriptive. The board holds whatever shape your story actually has, which is the point at which a template stops being a constraint.
AI that reads the whole board as context
An AI that helps with structure and does not write dialogue
Generate the first beat board: Describe the premise and the AI lays out beats across the acts. Most will be conventional, which is useful, because knowing the conventional version is how you decide what to do differently.
Interrogate the shape: Ask where the midpoint is doing no work, which character has no beat in act two, or what the story promises in act one that it never pays off. The AI uses your whole board, so it answers about your story.
It structures, it does not ghostwrite: Storyflow arranges and suggests. It does not write your scenes, and a screenplay drafted by a model reads exactly like one, which is not a service to anybody.
Re-prompt without losing your work: Ask for an alternative act three and it builds around what you have placed. The beats you positioned and connected stay exactly where they are.
Co-writers, producers, and the room
Share the structure without sharing a draft
View-only links: Send a link and a co-writer, a producer, or a script editor opens the whole board in a browser with no account. Structural notes given against a board are far more useful than structural notes given against a draft.
A writers' room on one canvas: Invite people onto the board and break a season together, with each episode as a section and the series arcs running underneath.
Comments on the beat in question: A note about the midpoint sits on the midpoint card. Nobody has to reconstruct which beat a comment in an email was about.

Every template opens as a real, editable board on the infinite canvas. Pick the closest fit and make it your own.

HOW WE COMPARE
Storyflow vs WriterDuet, Final Draft, and Scrivener.
These are not really competing: WriterDuet and Final Draft are script editors, Scrivener is a long-form writing environment, and this is a planning canvas. Here is what each actually does.

WriterDuet alternative questions, answered.
What each tool is for, what you give up, and how the handoff works.
No, and it is worth being direct about that. WriterDuet is a screenwriting application: it formats a screenplay to industry standard, paginates, handles production revisions and coloured pages, and lets two people type in the same document at once. Storyflow does none of those things. What it replaces is the part of WriterDuet that was never its strength, which is the planning: outlining, index cards, and structure. Most writers who use both do the structural work on a canvas and then write the actual pages in a script editor. If your problem is that the script will not come because the shape is wrong, a better script editor will not help you, and that is the specific case this is built for.
Fix the shape before you write the pages.
