What is an AI screenwriting tool?
A screenwriting tool can mean two different things, and the difference matters before you pick one. There is screenplay formatting, which is the editor that turns your scenes into industry-standard pages with the right margins, sluglines, and dialogue blocks. And there is screenwriting development, which is the work that comes first and runs alongside it: breaking the story into beats, finding the structure, writing character profiles and treatments, building the world, and planning what each scene needs to do.
Storyflow is the AI screenwriting tool for the development half. Describe your film, your series, or your short, and the AI lays out beat sheets, story outlines, character profiles, and scene cards on an infinite canvas. Beats sit in order, characters get their own cards, and scenes line up the way the story moves, all as cards you can drag, edit, and delete. It works the way writers think when they break a story on a wall of index cards, but with AI doing the first pass and a storyboard one click away.
To be clear about what it is not: Storyflow does not format a screenplay or export to Final Draft. It does not produce the .fdx pages your editor reads. It is where you figure out what the story is before you write those pages, and where you keep developing characters and scenes while you write them. When the pages get written in a screenplay editor, Storyflow is the board the writing came from.
HOW IT WORKS
Develop a screenplay with AI in four steps.
You bring the premise. The AI lays out the beats, characters, and scenes, so your attention stays on the story.
01
Open a free canvas
Start in the browser with a free account. There is no app to install and no card to enter, just an empty canvas ready for the story you want to break.
02
Describe your film
One line is enough: a heist thriller in three acts, a coming-of-age short, an eight-episode drama. Add the genre, the logline, or the ending you are chasing.
03
AI lays out the story
The AI places beat cards in order, character profiles, a treatment, and scene cards on the canvas, grouped so the shape of the story is visible at a glance.
04
Rework, storyboard, keep developing
Drag beats to restructure the acts, ask the AI to deepen a character, storyboard the key scenes on the same canvas, then share a view-only link or export as image or PDF.
A screenwriting tool that works before the pages.
Most story work lives in scattered notes and a blank script. Here the beats, characters, and scenes share one canvas.
Beats and structure from a single prompt
From a logline to a beat sheet
Describe the film and the AI breaks it into beats laid out in order on the canvas: setup, turns, midpoint, climax. See the whole structure, then move the beats that are in the wrong place.

Characters that get their own cards
Build the cast, not just the plot
The AI drafts a profile for each character: want, need, wound, and arc. Keep them visible beside the beats so the structure and the people stay connected as the story changes.

From beats to scenes you can see
Scenes become storyboards
Pick a sequence and ask the AI to turn it into a storyboard, scene by scene, on the same canvas the beats came from. Visualize the key moments before you write the pages.

Room for the whole story
An infinite canvas to break the story
A feature has acts, threads, and a full cast. With an infinite canvas and no object cap on the free plan, the beats, characters, world, and scenes all fit on one board.

BREAK THE STORY
Built for the way screenwriters develop a story.
Lay the beats on a wall, group the characters and threads, and keep the whole structure visible at once.
Cards you can move, edit, and reorder
Index cards that work like a story wall
Beats as movable cards: Beats and scenes are laid out as cards in order, so the structure of the film is visible without a locked template forcing the shape.
Drag to restructure the acts: Move a beat and the act moves with your thinking. Swapping the order of two sequences is a drag, not a rewrite.
Expand any beat: Ask the AI to break one beat into the scenes that fill it while the rest of the structure stays exactly as you arranged it.
Context from the board you are developing on
AI that builds on the story so far
Reads your active board: The AI uses what is on the board you have open, so new beats and scenes stay consistent with the characters and structure you already laid out.
@-mention your sources: Add up to one Blueprint and three documents as context: a treatment, a research doc, or a character bible the AI should develop the story from.
Re-prompt to refocus: Ask for a darker third act, a tighter midpoint, or a different inciting incident. The AI reworks the layout while keeping the cards you wrote.
More than text on every card
References, notes, and world-building on the canvas
Drop in anything: Location stills, casting references, mood images, PDFs, and links attach to the canvas next to the scenes they support. Build the world beside the story.
Frame grabs from video: Capture stills from YouTube and Vimeo straight onto the board when a film reference frames a scene better than a description.
Notes where you need them: Treatments and longer scene notes live as documents on the same canvas, so the board stays scannable and the depth stays one click away.
Development is step one, not the pages
From story board to the scenes you shoot
Storyboard the key scenes: Turn a sequence into a storyboard on the same canvas, with the AI carrying the beats over, so the story you broke becomes scenes you can see.
Share the development: Invite a co-writer or a director free, or send a view-only link so anyone can explore the board without an account.
Export as image or PDF: Need the beat sheet or storyboard in a pitch deck or a doc? Export it as a clean image or PDF in one step.
WHO IT IS FOR
Who develops screenplays with AI?
Anyone breaking a story before the formatted pages get written.
Screenwriters breaking a feature
Lay the beats for all three acts, profile the cast, and rework the structure as cards before opening Final Draft to write the pages.
Filmmakers planning a short
Map the story, build the world, and storyboard the key scenes on one canvas, then take the board into pre-production. Free, with no time limit.
Series writers in a room
Break a season into episode beats, track character arcs across the cards, and walk the room through the structure with a view-only link.
Directors developing a vision
Pin location stills and references beside the beats, frame the key scenes as a storyboard, and keep the look and the story on the same board.
Students learning structure
Generate a beat sheet from a logline, expand the beats you are unsure about, and pin the scripts you are studying beside the structure they teach.
COMPARED
How Storyflow compares to other screenwriting tools.
Most screenwriting tools focus on formatting the pages. Storyflow focuses on developing the story they come from.

What creators are saying
Join early creators getting structured workspaces and AI that remembers their projects
“Storyflow has sped up my workflow by at least 3x, which means more flow state and more projects I can actually ship. It truly changed the way me and my team create.”
Reilin Joey
Director & YouTuber
“One prompt gets me a structured board. But the tactics are my favorite. I run my YouTube scripts through them and my intros and retention got better. It's amazing.”
Justkay
YouTuber & Freelance Filmmaker
“I used to juggle five apps to plan a project. Now I describe what I am making and get boards, lists, and a schedule. All in one place.”

AI screenwriting questions, answered.
Everything people ask about developing a screenplay with AI in Storyflow.
No. Storyflow develops the story, the beats, the structure, the characters, the scenes, and the storyboards, but it does not format industry-standard screenplay pages and does not export to .fdx or Final Draft format. It pairs with a screenplay editor such as Final Draft, WriterDuet, or Fade In: you break and develop the story in Storyflow, then write the formatted pages in the editor.
The story is in your head. Break it on the board.
