AI Social Media Post Generator.
Feed-Ready Imagery From a Prompt

A social post is not a poster shrunk down. It is an image competing inside a scrolling feed, seen for a fraction of a second, at a size you do not control. That changes the brief in three ways.

First, ratio. Every platform crops differently, and an image built for one feed will lose its subject in another. Second, safe zones. Profile overlays, captions, and call-to-action buttons sit on top of your image in some placements, so the important part of the composition has to sit inside a margin. Third, legibility at thumbnail size. If the subject does not read when the image is the size of a thumbnail, nothing else about it matters.

This page covers generating imagery for social feeds generally. For static design outside a feed — print, display, wall posters — the ai poster generator overview is the better starting point.

The most common mistake in AI-generated social imagery is asking for text. The model produces letterforms that look plausible at a glance and are wrong on inspection — misshapen characters, broken spacing, occasionally words that do not exist.

There is also a strategic reason to avoid baked-in text. Text rendered into an image cannot be edited, cannot be translated, cannot be resized, and cannot be read by screen readers. Caption text is searchable, accessible, and editable after the fact. Image text is a dead end.

So treat the image and the copy as separate layers. Generate the artwork with the area for a headline deliberately left empty, then set the headline in your design tool or leave it to the platform caption entirely. A striking image with a well-written caption typically outperforms a mediocre image with the words burned into it.

Social is a volume game in a way that print never is. A month of posts across three platforms is easily thirty or forty images, and the previous approach — stock photography plus a template — produces a feed that looks like everyone else's.

Generation changes the economics of that volume. Credits start at $10 per 1,000 and do not expire, so a month of social imagery costs a few dollars rather than a stock subscription. Because the credits do not expire, a heavy month does not waste the allowance from a quiet one — which is exactly the mismatch a monthly stock plan creates.

The practical discipline for volume is to fix one prompt per format. Keep a saved prompt for the 4:5 announcement, one for the 1:1 product shot, one for the 9:16 story. Then each new post changes a single variable — the subject or the colour — and the set stays visually coherent instead of drifting.

Everything generated on a paid plan carries a full commercial licence, covering organic social, paid social, and print. The free tier is for evaluation rather than commercial use.

Two limits are worth knowing before you plan a campaign around this. Generated imagery is original rather than stock, which removes the licensing problem stock photography usually brings — but it does not give you rights in someone else's trademark, a real person's likeness, or a protected character. Describe styles generically rather than asking for a specific protected work.

And the licence covers your use of the image, not the truth of any claim you place on it. If a post asserts something about a product, that assertion is yours to substantiate — the image generator has no opinion about it.
