TV SERIES PLANNER
Every episode has to satisfy on its own while the season arc advances underneath it. Put the episode row and the season arc row on one infinite canvas, run character arcs across years below them, and keep the series bible on the same board. Storyflow is paid-only during early access, with plans from $9.99 a month, and a Free plan launches before the end of 2026.

A TV series planner is a tool for working out what happens in a show, at two scales at the same time. A novel has one clock. A series has two, and they run against each other. Tonight's episode has to open, escalate, and land a satisfying ending inside forty-odd minutes, because most viewers judge a show on the hour in front of them. Underneath it, the season arc has to move a measurable distance, or the show is a set of unrelated instalments wearing the same title card. A series planner is where you make sure both of those things happen in the same forty minutes.
That double clock is why series planning breaks linear documents so badly. To check whether episode five earns its ending, you read episode five. To check whether the season arc is advancing, you read the arc across all eight episodes, which means holding fragments of eight documents in your head at once. Then there is a third scale on top: a character arc that resolves in season three has to be seeded in season one, and a payoff you plant in the pilot is worthless if nobody remembers planting it. A document only ever shows you one page, so the questions that actually matter in television are the ones a document cannot answer.
Storyflow is an AI-native infinite canvas built for exactly that geometry. Describe the show in a prompt and the AI lays out a season board with episode cards, act structure, and the arc beats underneath. Then you drag episodes into a new order, run the season arc as a track directly below the episode row, give each recurring character an arc track that spans seasons, and pin the series bible, the world rules, and the reference material on the same canvas. Because the episode row and the arc row are stacked, a gap in an arc is a visible hole rather than something you have to reconstruct by reading.
Planning a series usually means working across six connected layers: the series engine and premise (the machine that generates a story every week, and the promise the pilot makes about what the show is), the season arc (where the serialized spine starts, turns at the midseason, and lands in the finale), episode structure (cold open, act breaks, and the A, B, and C stories that braid inside one hour), character arcs across seasons (what each character believes at the start of the run, what breaks it, and which season it breaks in), the series bible and continuity (canon, world rules, timeline, and the facts every writer has to obey), and the writers-room process (breaking a season on a board of cards, assigning episodes, and keeping many hands working from the same version). Storyflow keeps all six visible at once, which is the only condition under which the structural problems become findable.
HOW IT WORKS
No episode database to configure and no template to fight. Describe the show and start moving cards.
01
Sign up in seconds, from $9.99 a month. No download. Your infinite series canvas opens in the browser.
02
Type the premise, the genre, the engine that generates episodes, and the season length. The AI lays out a season board with episode cards, act structure, and arc beats underneath, so you start from a skeleton rather than a blank room.
03
Drag episode cards until the order works. Run the season arc as a track below the episode row, braid the A, B, and C stories inside each episode, and mark what gets seeded now and paid off later.
04
Invite your writers to the same canvas, or share a view-only link with a producer, an executive, or a manager. Export the season board as an image or PDF when it has to travel into a pitch document.
Episode beats, season arc, multi-season character arcs, and the bible on one infinite canvas.

AI builds a season board from your premise
Type the premise and the season length and the AI lays out episode cards against a structure, with the midseason turn and the finale placed and the gaps visible. Arguing with a bad first pass is much faster than staring at an empty board.

Episode row above, season arc row below
Put the episodes in a row and run the serialized spine as a track directly beneath them. An episode that satisfies on its own but moves the arc nowhere is instantly obvious, and so is the run of three episodes where the arc does all the work and nothing lands.

Character arcs that span seasons
Give each recurring character a track that runs the whole show, not one season. When you can see season one and season three on the same canvas, planting the moment that pays off later stops being a thing you hope you remembered and becomes a thing you placed.

The bible lives beside the board it governs
Canon, world rules, timelines, and character facts sit on the same canvas as the episodes that have to obey them. A bible in a separate document is a bible nobody opens in the middle of breaking an episode.

BUILT FOR TELEVISION
A folder of episode outlines hides the exact thing television lives or dies on: what the season is doing while the episode is doing its job.

Cold open, act breaks, and the A, B, and C stories
Structure the hour properly: Lay out the cold open, the act breaks, and the tag as cards. Act breaks are the load-bearing beats of commercial television and the strongest structural discipline in streaming too, because a break that does not make someone stay is a break in the wrong place.
Braid the A, B, and C stories: Run the A story, the B story, and the runner as parallel lanes inside a single episode, then check where they intersect. Three plots that never touch is three short films; the braid is what makes an episode feel like one thing.
Keep the procedural and the serial in balance: Mark on each episode card how much is self-contained and how much is serialized. Seeing the ratio across a whole season is how you catch the drift into pure serialization that leaves every individual episode feeling like a middle chapter.
The pilot has a different job: A pilot is not episode one, it is the argument for the series. Lay out what it establishes: the engine that generates a story every week, the cast dynamic, the tone, and the promise the show is making. Then check that episode two can actually deliver on it.

The season arc, the midseason turn, and the finale
The arc as a track under the episode row: Place an arc beat on the track wherever the serialized story genuinely advances. An empty stretch under three consecutive episodes is the run where viewers say the show lost momentum, and on a stacked board you can see it before you write it.
Place the midseason turn deliberately: The middle of a season is where a show either changes its own premise or starts repeating itself. Put the turn on the board, look at what sits either side of it, and check that the back half is a genuinely different situation rather than more of the front half.
Setups and payoffs across episodes and seasons: Mark what is planted and where it detonates, then draw the connection across the canvas. Setups with no payoff are broken promises, and payoffs with no setup are the coincidences audiences call cheating. Both are visible the moment the lines are drawn.
Season two exists on the same canvas: Put next season beside this one rather than in a new file. Deciding what the finale withholds is a decision about season two, and you can only make it well if season two is something you can look at.

AI that can see the whole show, not one episode
Ask questions only the whole board can answer: Ask where the season arc goes quiet, which two episodes are structurally identical, whether a character has anything to do in the back half, or what the finale is currently promising about season two. It reads the entire canvas, so the answers are about your show.
Break from a premise, then argue with it: Have it lay out a first-pass season, then throw out the half you hate. A room does its best work reacting to a bad idea on the wall, and a first pass you can reject is worth more than a blank board you are still respecting.
It structures, it does not ghostwrite: Storyflow is a planning canvas rather than a script generator. The AI helps you see and arrange the show, which is the genuinely hard part of television. What the characters actually say stays yours, and it belongs in your script software.
Iterate without losing the room's work: Re-prompt as many times as you need. Cards the room already wrote and placed stay exactly where they are while the AI builds around them, so a regenerate never costs you a morning of breaking.

A writers room, a producer, and a buyer
Break the season together on one canvas: The room works on the same board rather than on one person's notes plus a photo of a corkboard. Cards move in front of everyone, so the version on the wall and the version in the file are the same version. Anyone a paid member invites to a board joins free today.
Assign episodes and keep the bible honest: Hand an episode to a writer with the season arc, the character tracks, and the canon visible beside it. Most continuity errors are not carelessness, they are a writer who could not see the fact they were about to contradict.
Show the season instead of describing it: Send a view-only link to a producer, an executive, or a manager and they open the whole shape of the season in a browser with no account. A stacked board makes a structural conversation far more concrete than a document of episode summaries.
Export for the pitch: Export the board as a high-quality image or PDF when the season has to live inside a pitch document, a deck, or a bible you are sending out. Read how the pieces fit together in our guide to planning a TV pilot with AI.
Every template opens as a real, editable board on the infinite canvas. Pick the closest fit and make it your own.
Outline your plot, characters, and world in one connected view, then expand each thread as the story grows.

HOW WE COMPARE
Every tool here is genuinely good at something, and one of them owns a job we do not do at all. Here is where they differ.

How to break a season, how long it should be, and where a canvas beats a document.
Start with the engine, not the plot. Work out what generates a story every week, because that is what makes it a series rather than a long film. Then break the season: put every episode on its own card in a row, and run the serialized arc as a track directly underneath. Place the midseason turn and the finale early, since they are the two beats everything else is shaped around. Only then fill in each episode with a cold open, act breaks, and the A, B, and C stories. Finally, run each character's arc across the whole row and check that nobody goes quiet for a third of the season.
