Keep scrolling — the page fills as you go
Step one
You arrive with almost nothing.
A woman, a house, a feeling you can't name yet. That is a completely normal place to start, and StoryProp does not ask you to fill in a form before it will talk to you.
YouI want something about a woman who's been pretending for a long time. Small town. I don't know the ending.
Step two
Lock in one thing at a time.
Not a questionnaire. A conversation. We give a couple options, recommendations if you want one. What you agree to gets written down. What you don't stays a suggestion.
StoryPropTwo ways in: she's protecting someone, or she's protecting a version of herself. The second is harder to resolve and better television.
Step three
Structure shows up when it's useful.
No framework is imposed. When shape would actually help you decide something, it appears in the conversation as a suggestion you can take or leave.
StoryPropIf the neighbour arrives in the cold open, the audience knows before she does. That's the whole engine of the pilot.
Step four
Then it writes — a little.
An opening situation. A paragraph or two. Then it hands control back and waits, because a whole chapter you didn't ask for is not help.
StoryPropHere's the opening image. Tell me if the cup is too much.
60 minutes later
You have a page and a project.
Not a finished pilot. Something better at this stage: a real opening, characters that exist on paper, decisions recorded with the reasoning that produced them, and a partner that will remember all of it tomorrow.
Most writing tools show you an empty page.
Premise
A woman who has spent nine years perfecting an ordinary life discovers that the person most likely to expose her has moved in next door.
Characters
- Mara — protecting a version of herself, not a secret
- Daniel— the neighbour; knows, and hasn't said
Shape
- Cold open: the audience learns before Mara does
- Act one: the invitation she cannot refuse
- Act break: he uses her real name
Opening
The room was dark except for the kitchen. Mara set out two cups without being asked and turned the chipped one toward herself, so that the flaw faced in.
“You knew I was coming?” Daniel said.
Saved to the project
- Canon · Characters · Shape · Draft history
- Every decision, with the conversation it came from
What you walk away with
A project, not a transcript.
Everything above is still there when you come back — not as chat history you have to scroll, but as records the agent reads before it writes anything else.
01
The draft
Real pages in the format's real conventions, editable by you at any point, and clean on export: no watermark, no notice, nothing of ours.
02
What's true
Canon, characters, and the decisions you locked — kept apart from the ideas you only floated.
03
Where it came from
Every research source it used, with provenance and dates, filed without you ever filing anything.
04
Every earlier version
Grouped into sessions and agent passes, comparable, restorable, and searchable alongside the current draft.
The part that compounds
Tomorrow it still knows.
The first session is the easy one. The difference shows up in month four, when you open a project you have not touched in three weeks and it picks up mid-thought.
Starts over, politely
You re-explain the premise, re-paste the chapter, re-establish who knows what. The context window is the memory, so the project only exists in your head and your clipboard.
Reads the project first
The conversation is permanent and ordered, the records are authoritative, and every draft is retained. Ask what you decided about the ending in March and it can find the turn where you decided it.
One agent, five families
Whatever form the work takes.
The same partner, the same conversation. What changes is the page — each format is set in the conventions it is actually judged by.
01
Novels
Premise, outline, characters and continuity across a whole book — drafted a scene at a time.
02
Screenplays
Proper Hollywood pages. Sluglines, action, cues and dialogue set themselves as you write.
05
Essays & nonfiction
Argument, evidence and sources — without narratology imposed on work that has no plot.
Writer authority
What it won't do.
Most of the fear about writing with an agent is fear of losing the thing you were making. These are constraints, not preferences.
- 01It won't write a chapter you didn't ask for. Drafting is small by default — an opening, a paragraph or two, then back to you.
- 02It won't edit something you didn't point at. A scoped instruction changes that passage. The rest of the scene is left alone.
- 03It won't make a creative decision for you. It recommends, explains why, and waits. Suggestions stay suggestions until you say otherwise.
- 04It won't quietly turn a brainstorm into canon. What you approved and what you were only thinking about are kept apart on purpose.
- 05It won't put its name on your work. No watermark, no branded filename. It’s your work, your ideas. We’re just the tool.

Fair questions
Before you sign up.
What is StoryProp, exactly?
A project-aware AI writing agent: your manuscript on one side, one persistent creative partner on the other, both working on the same document. You direct it in plain language — develop this premise, tighten this scene, hold this voice — and it does real drafting and revision work under your direction.
What does early access mean here?
StoryProp is live and paid, and still being finished in the open. You get the real product — the workspace, the agent, professional exports — while the rough edges are honestly rough. Your work and your history carry forward.
How is this different from ChatGPT or another general chatbot?
A general chatbot starts over every session: you re-paste the chapter, re-explain the premise, re-establish who knows what. StoryProp keeps the project — permanent conversation, authoritative records, every draft — and reads it before writing anything.
The other difference is discipline. It revises what you point at instead of regenerating everything, drafts small by default, and leaves creative decisions where they belong: with you.
Can it really remember a whole project?
The project conversation is permanent and ordered, your locked decisions live in project records, and every draft is retained and searchable. The agent reads from all of that before it writes, which is what keeps months-long work coherent.
Will it write the whole thing for me?
Only when you ask it to, in so many words. The default rhythm is deliberately small — an opening, a paragraph or two, then back to you — because a chapter you didn't ask for is not help. An explicit request for a chapter or a whole draft runs that full scope without nagging you between sections.
What kinds of writing does it support?
Five families: books and prose (novels, short fiction, memoir, nonfiction), movie screenplays, television and episodic scripts, stage plays, and general writing from essays to speeches to articles. Script formats get true professional layout; prose gets a clean, familiar editor.
Who owns what I make?
You do. As between you and StoryProp, it claims no authorship or ownership in your input or the output, and exports carry no StoryProp branding of any kind — your byline, pen name included, and nothing of ours.
