How to Brainstorm a Story with AI: Loglines, Twists and Beats
How to brainstorm a story with AI without letting it write for you: start from a seed, get ten loglines, then dig with follow-up questions. You keep the choices, the assistant explores the directions.

In this lesson you will learn
- Why you start with a story seed and constraints instead of asking for a finished story
- How to read ten AI loglines as a map, and spot the generic ones
- How follow-up questions turn a logline into a midpoint and a plot point two
- How to get a seven-beat skeleton using the structure labels
- The most underused question in AI writing: asking for criticism
- How to brainstorm backstories and character names that shape every line
The blank page is hard because every direction is possible, and an AI assistant can explore a dozen of them in a minute. This lesson shows how to brainstorm a story with AI and still choose like a writer. We start from a seed for The Night Ferry, an old ferryman who never takes passengers after midnight, add constraints, and ask for ten loglines for a five-minute short film.
Then we read the answers as a map, not a menu, ask follow-up questions that produce the engine and the compass, our midpoint and plot point two, and request seven story beats from opening to resolution. You will see how asking for criticism fixed a passive low point, how one backstory shaped Elias without ever being said, and how the names Elias and Maya were chosen. Lesson 4.2 of a free screenwriting course in ScreenWeaver.

0:04The blank page is hard because every direction is possible. An AI assistant is very good at exactly that problem, exploring a dozen directions in a minute. So you can choose, like a writer.
0:17Start with a seed, not a request for a finished story. Here's mine. An old ferryman crosses a lake at night. He never takes passengers after midnight. Tonight, someone begs him to cross. Then the constraints. Give me ten log lines for a five -minute short film with two characters. Vary the genre and the twist. One sentence each.
0:40Read the answers as a map, not a menu. Some are generic. A ghost, a dream, a murder. That's the average of everything the model has read. Others are interesting. Number seven. The passenger is his daughter, whom he hasn't seen in years. That's a twist you can show on screen, with an object, without explanation.
1:02Now go deeper, with follow -up questions. Give me five ways she could prove who she is, without saying it. The answers? She knows a nickname. She sings a song. She fixes the engine the way he taught her. She carries a matching object. The last two become our midpoint, and our plot point two. The engine, and the compass.
1:23Then ask for structure. Here's my log line. Give me seven story beats, using the labels opening, inciting incident, plot point one, midpoint, low point, plot point two, and resolution. You get a skeleton in seconds, ready to compare with the outline you built yourself.
1:43And ask for criticism. This is the most underused question in AI writing. What's the weakest beat of this outline, and why? The assistant pointed out that the low point was passive. Elias was just worried. So we made it active. He demands, who are you? And she refuses to answer.
2:02Brainstorm characters, too. Ask, give me five possible backstories for Elias that would explain why he never sails after midnight. One answer was perfect. The night his daughter left, she took the last ferry. After midnight. We never say it in the film. But knowing it changes how we write every one of his lines.
2:22And names. Names carry a lot. Ask for ten names for an old ferryman. And ten for his daughter. With a short reason for each. Elias came from that list. Old. Simple. A little biblical. Maya. Short. Modern. Easy to call across the water.
2:47Remember, the assistant is a sparring partner. You accept, twist, or throw away. The best ideas of the night fairy came from rewriting the assistant's answers, not from copying them.
3:01Your exercise. Write your seed. Ask for ten log lines. Choose one. Ask five follow -up questions. Ask the assistant to criticize your outline. Next, writing and rewriting scenes with AI. Bye. Bye
