Movie Poster Generator
Pitch a title, a genre, and an audience. The agent writes a real creative strategy and renders a batch of cinematic poster concepts — no designer, no brief deck, one canvas you re-run for any film.
How it works
A handful of nodes do the work. A brief becomes a strategy, the strategy becomes concepts, the concepts become key art.
01Set the brief
Three text inputs hold the film's title, its genre, and the audience you're selling to. That's the entire creative input.
Singularity · Sci-Fi · AI Enthusiasts
02Write the strategy
A Prompt node frames the brief and an agent returns a real creative strategy: positioning, audience insight, a core visual concept, and a color palette.
Positioning · audience insight · hex palette
03Spin up concepts
A list generator turns the strategy into a batch of distinct plot angles, so one run gives you a spread of directions, not a single guess.
Five plot concepts per run
04Render the key art
Each concept is templated into a full theatrical poster prompt, then an image model renders it, title, tagline, billing block and all.

One title. Five concepts.
Same brief, a fresh strategy each run. Here is Singularity rendered as five poster concepts, straight off the canvas.
Direct it yourself
Nothing here is locked. Swap models, shift the tone, re-roll a concept, or point the whole thing at a different title.
Swap the image model
GPT Image-2, Flux, Nano Banana, Ideogram. Change one node and the whole batch re-renders in a new look.
Shift the tone
Change the genre or audience and the strategy, palette, and posters all follow, no manual re-briefing.
Edit the poster recipe
The poster Prompt node owns the composition, typography, and billing-block layout. Tune it once, every render obeys.
Batch any title
Drop in a new title and run it again. The workflow is the reusable part; the posters are just this run's output.
Models in this workflow
Called with your own keys. The bill comes from the provider, not from us — no token markups — and you can switch any of them for a better model the day it ships.
Frequently asked questions
- How do you generate a movie poster with AI?
- In NodeTool it takes four nodes: enter the title, genre, and audience; an agent writes the creative strategy; a list generator turns it into distinct plot concepts; an image model renders each concept as a full theatrical poster, title, tagline, and billing block included.
- Which models does this workflow use?
- Gemini 3.1 Pro Preview writes the strategy and the plot concepts, and GPT Image-2 renders the key art. Both are called with your own provider keys at provider prices.
- Can I swap in a different image model?
- Yes. GPT Image-2, Flux, Nano Banana, and Ideogram are one node apart — change the model and the whole batch re-renders in the new look, with the rest of the workflow untouched.
- Do I need a designer or Photoshop?
- No. The poster Prompt node owns the composition, typography, and billing-block layout, so each run produces finished poster concepts. Drop in a new title and run it again — the workflow is the reusable part.
