Turn your brand brief into a model-ready image prompt

Three prompt directions with the subject, composition, lighting, camera, palette and constraints broken out separately. Edit any decision and the complete prompt rewrites itself.

What the product is, what it does, and any distinctive brand cues. Everything the prompts claim has to come from here.

0/2000

Sets the target canvas and ratio the composition is written for.

Image models render lettering unreliably. Leaving clear space for real typesetting is usually the better commercial choice.

0/240

A factual point the image should communicate. Used as written or not at all.

0/240

Names or hex values. Anything you do not supply is labelled a suggestion rather than presented as your brand colour.

0/120

An observable object, prop, scene or brand element.

0/240
0/400

Free, no signup. Fair-use limits apply.

Use public, non-confidential information only. Your brief is sent to our AI provider to generate prompt text and is not included in product analytics.

Three prompt directions will appear here, each with editable subject, composition, lighting, camera, palette and constraints.

Why this one

What this tool gets right

The prompt is legible, not magical

Every visual decision is its own field. When an image comes back wrong you can see which instruction caused it and change that one, instead of rewording a paragraph and generating again.

Three directions, one brief

Product clarity prioritises comprehension. Campaign concept brings a stronger commercial idea. Channel native protects the placement. Pick the one that matches the job.

Honest about typography

Image models render lettering badly. The default reserves clean space for real typesetting rather than pretending a model is a reliable layout tool, and says so when you override it.

Grounded negatives

The avoid list names failure modes relevant to your image and everything you excluded. Not a copy-pasted wall of negative keywords that applies to nothing in particular.

How it works

Three steps, about thirty seconds

01

Describe the product or brand

What it is, what it does, and how it should look. Every claim in every prompt has to come from this, so specifics pay off immediately.

02

Pick the goal and the placement

The placement sets the target canvas and ratio the composition is actually written for, which is the part most prompts skip.

03

Edit the decision that is wrong

Change the lighting, tighten the composition, swap the palette. The complete prompt recomposes as you type, then you copy it into whichever model you use.

A useful prompt is more than a string of style words

A generic prompt can describe an attractive image and still miss the product, the placement and the commercial job. This AI image prompt generator starts from the constraints instead: what the product actually is, what the image needs to achieve, where it will appear, which elements and colours matter, and what it must avoid. Then it separates the visual decisions so you can inspect them. Subject tells the model what deserves attention. Composition establishes hierarchy and safe space. Lighting, camera and palette shape the visual language. The result is a prompt you can reason about rather than one you rerun until something works.

Why the negatives matter as much as the description

Most of the distance between a usable commercial image and a discarded one is failure modes: a fake logo, unreadable interface text, an extra hand, a lens flare nobody asked for. Naming the ones that are actually plausible for your image removes them far more reliably than a generic negative list copied between projects. Anything you exclude goes into that list verbatim, and the tool checks that it did. If you need a prompt for an AI image generator that respects a hard constraint, that check is the difference between finding out now and finding out after you have paid for the generation.

Check the prompt before you generate an image

  • This free tool creates prompt text only. It does not generate, edit or evaluate an image.
  • It does not read product URLs in this version. The prompts use only the brief you paste.
  • It does not verify claims, trademarks, rights, platform policies or model policies.
  • Image models may ignore instructions and often render text, logos, hands and interfaces incorrectly.
  • Suggested palettes are not your official brand colours unless you supplied and verified them.
  • A prompt cannot promise originality, legal safety, ad performance or conversion.
  • Channel dimensions are common placement sizes, not a guarantee of platform compliance.
  • Do not enter confidential, private or internal information.

Questions, answered

Yes. Generate, edit, select and copy all three prompts without an account. A fair-use limit caps how many runs you get in an hour, and it resets automatically.
No. It writes prompt text. You get the subject, composition, lighting, camera, palette, typography constraints, negative instructions and channel format, ready to paste into whichever image model you use. Advibly, the paid product behind this, is where the actual generation happens.
Not in this version. Paste a brand brief instead, describing what the product is and what makes it distinctive. Fetching an arbitrary page from our servers needs security work that is not done yet, so the tool does not offer it rather than doing it badly.
Three directions, which are product clarity, campaign concept and channel native. Each has eight editable visual fields, one complete copyable prompt, and a note on what it is good for and what it gives up.
The output is model-neutral, structured prose that reads cleanly in any of the current image models. As an AI prompt image generator it makes no claim that a given provider will follow every instruction, because none of them reliably do.
If you supply them, exactly as written. If you do not, any palette it proposes is labelled a suggestion rather than presented as your brand's, because it has no way of knowing what your colours are.
You can ask for a short headline, and the prompt will say plainly that it will probably come out wrong. The default reserves clear space for you to typeset over afterwards, which is what most commercial work ends up doing anyway.

Words are the easy part. Advibly makes the creative.

Advibly turns your brand into finished ads: product-in-hand UGC videos, static image ads, carousels, and explainers. Same thinking as this free tool, pointed at the thing that actually takes time.
