AI Prompt Generator for Image Prompts

Use this existing Omellody utility to turn a rough image idea into a complete prompt package with subject, style, lighting, composition, format, negative prompts, and reusable variations. The builder runs locally in your browser and does not send your inputs to Omellody.

Direct answer: A strong image prompt generator names the subject, use case, visual style, lighting, composition, exact output format, and defects to avoid. The safest workflow is to generate a structured prompt package, review it for rights and accuracy, then adapt model-specific syntax only at the end.

Act as a senior AI image prompt director. Build a complete prompt package for the visual request below. Subject: {subject} Visual style: {style} Lighting: {lighting} Composition: {composition} Important details: {details} Output format: {format} Negative prompt: {negative} Return: 1. A concise main prompt ready to paste into an image model. 2. A detailed prompt with camera/style language, texture, color, and composition notes. 3. A negative prompt that removes common defects. 4. Three variations: clean/minimal, dramatic/editorial, and conversion-focused. 5. A review checklist for accuracy, rights, readability, and brand safety. Rules: avoid living-artist imitation, copyrighted characters, trademarked logos, misleading claims, private data, and confidential campaign details unless the user confirms rights and safe use.

Prompt formula and variables

Formula: Subject + use case + style + lighting + composition + material details + output format + negative prompt + variation request.

VariableWhat to enterExample
{subject}The main product, scene, person, object, or thumbnail concept.a reusable insulated water bottle for remote workers on a clean desk
{style}The visual direction: photorealistic, editorial, 3D render, minimalist, cinematic, illustrated, and so on.photorealistic commercial product image
{lighting}Light source, contrast, mood, shadow quality, and any reflection constraints.soft side light, gentle shadow, warm neutral highlights
{composition}Framing, camera angle, focal hierarchy, crop, copy space, and background relationship.centered hero shot, shallow depth of field, uncluttered negative space
{details}Textures, props, colors, audience clues, brand constraints, and factual limitations.matte finish, condensation beads, laptop edge in background, no visible logo, premium everyday feel
{format}Aspect ratio, platform, crop, resolution target, and any safe-zone requirements.4:5 portrait for social and landing-page hero crops
{negative}Defects, misleading elements, rights risks, and visual artifacts to avoid.blurry, distorted hands, unreadable text, extra bottles, watermark, trademark logo, low resolution

Decision card: which prompt path should you use?

GoalBest starting pointExtra variable to add
Landing-page heroProduct hero or scene-setting prompt with strong copy space.Above-the-fold crop, CTA-safe blank area, and brand palette.
Ad creativeConversion-focused variation with one visual promise and one audience cue.Hook placement, mobile crop, compliance-safe claim wording.
Editorial imageDocumentary or magazine-style prompt with factual context.Source context, realism level, and no misleading reconstruction.
ThumbnailHigh-contrast composition with one focal subject and readable empty space.Small-screen legibility, face/object scale, and background simplicity.

Model adaptation table

Model familyKeep from this generatorAdapt after generation
Midjourney-style toolsSubject, style, composition, lighting, aspect ratio intent.Move ratio and stylization into model flags if supported.
Stable Diffusion-style toolsMain prompt, detailed prompt, negative prompt, texture constraints.Separate positive and negative fields, then tune sampler/steps outside the prompt.
DALL-E / Gemini-style toolsPlain-language brief, rights-safe descriptors, output use case.Use shorter natural language and avoid overloading with parameter syntax.
Design workflow handoffDetailed prompt, review checklist, channel constraints.Convert model output into a human art-direction note before publishing.

Publishing score formula

Before using an output, score it with this lightweight formula: Prompt score = subject accuracy + channel fit + composition clarity + rights safety + defect control. Use a 0-2 score for each dimension; publish only results that reach 8/10 and have no rights or privacy failure.

Score dimension012
Subject accuracyWrong subject or misleading scene.Mostly correct with small ambiguity.Clearly matches the requested concept.
Channel fitWrong crop or unreadable at target size.Usable with editing.Ready for the intended platform crop.
Rights safetyUses risky names, logos, characters, or confidential assets.Needs one safety edit.Uses descriptive, rights-safe language only.

Use-case examples

NeedHow to tune the prompt
Product heroUse material, surface, background, practical use case, and a clean negative prompt.
Social creativeAdd audience emotion, hook space, crop ratio, and brand-safe visual constraints.
Consistent seriesLock palette, lens language, format, and recurring props across each variation.

Quality checklist

  • Describe visual qualities instead of copying a living artist.
  • Reserve text space instead of relying on generated text.
  • Ask for variations, then choose one direction before final rendering.
  • Check rights, brand fit, accuracy, and audience expectations before publishing.

Negative prompt checklist

  • Remove distortion, extra objects, watermarks, fake logos, unreadable text, and low resolution.
  • Add channel-specific problems such as cluttered thumbnails, harsh glare, or inaccurate product shape.
  • Keep negatives short enough that the model still follows the main prompt.

Output review logic

Score each result on subject accuracy, composition, channel fit, rights risk, text readability, and defect count. Regenerate only the weakest variable instead of rewriting the entire prompt when one dimension fails.

Review table before publishing

CheckPass conditionFix if weak
Subject accuracyThe generated image matches the requested product, scene, or thumbnail promise.Add material, shape, size, audience, and non-goals.
Rights and brand safetyNo unauthorized logos, characters, living-artist imitation, or misleading claims.Replace names with visual descriptors and remove risky claims.
Channel fitThe crop, focal point, and contrast work for the intended platform.Name the aspect ratio, mobile crop, copy space, and focal hierarchy.
Defect controlNo distorted text, warped faces, extra objects, or watermarks.Tighten the negative prompt and simplify the composition.
Privacy note: Do not paste unreleased campaign plans, customer data, private brand assets, credentials, medical/financial records, or confidential creative briefs into public AI tools.

FAQ

What should an AI image prompt include?
Include the subject, visual style, lighting, composition, important details, aspect ratio, and a negative prompt that removes common defects.
Can I use this with Midjourney, Stable Diffusion, DALL-E, or Gemini?
Yes. The prompt is model-agnostic. Adapt model-specific flags, negative-prompt fields, and aspect-ratio syntax after generating the core brief.
Should I ask for a living artist style?
Avoid requesting living-artist imitation. Describe the visual qualities you want, such as soft editorial lighting, loose watercolor texture, or high-contrast cinematic color.
Does the builder upload my inputs?
No. The form runs in your browser. Still avoid entering confidential concepts, customer data, unreleased campaigns, or protected brand assets into public AI tools.
