No more AI slop.
Stop struggling with basic prompts that give you random results. Poster Grammar is an AI art director agent that plans your concept, layout, typography and colour, then sends the master prompt to the image model to generate agency-grade posters.
No card needed.
Three things, done properly.
We start narrow on purpose. Every output is planned like a designer would plan it, then generated.
Product photography
Studio and lifestyle shots with real lighting, believable surfaces and your product kept true to its shape and colour.
See photo layouts →Posters & ads
Social posts, listings and campaign posters with one idea, a clear headline and room to breathe.
See posters →Video Coming soon
Short product films built on the same art direction, so motion looks as considered as the still.
Pick a format, start from a layout.
Every layout here was approved by a designer. Counts show what is in the library today.

Slop is what you get when a model guesses. We don't let it guess: four decisions are made first.
- 01
One idea
We read the product and the audience, then pick the one thing the visual must say.
- 02
A real layout
Product, headline and space are placed on a grid from a library of designer-approved compositions.
- 03
Art direction
Type, colour, light and setting are chosen for your product, never copied from a sample.
- 04
Checked
Crops, overlaps, contrast and copy are checked before anything reaches you.
Stop generating. Start directing.
