AI prompt generator

AI image prompt generator: from rough idea to model-ready prompt

Write the subject first, then add style, lighting, lens and aspect ratio as separate clauses. Copy a working structure from the public gallery, run it on a Genvizu image model, and change one variable per run.

Start free · no credit card

  • Ten image models in one workspace, from a 1-credit Z-Image draft to Midjourney 8.2.
  • Every public gallery page shows the prompt and the model that produced it.
  • Credit cost is shown on the generate button before you spend anything.

Three prompts you can run today

Each example starts from the kind of one-line idea people actually have, and ends with a prompt you can paste into an image model unchanged.

E-commerce product shot

Input

Rough idea: matte black insulated water bottle, clean hero shot for a product page

Prompt output

Matte black insulated water bottle on a pale grey seamless backdrop,
three-quarter angle, large softbox from camera left, subtle rim light
on the right edge, shallow depth of field, 85mm lens look, crisp
condensation droplets, generous empty space above the bottle for a
headline, photorealistic, 4:5

Ask for the empty space where the headline will go. If you leave it to chance, the product ends up centred and there is nowhere to put copy.

Editorial portrait

Input

Rough idea: portrait of a woman in her thirties, magazine feel, vertical crop

Prompt output

Editorial portrait of a woman in her early thirties, head and shoulders,
direct eye contact, natural skin texture, single window light from the
left with soft falloff, warm neutral wardrobe, desaturated olive
background, medium-format look, 50mm, shallow depth of field, calm and
confident expression, 4:5

Name the light source and the lens before you name the mood. Models follow concrete optics far more reliably than adjectives such as "cinematic".

Poster key visual

Input

Rough idea: poster for an indie electronic music festival, summer, night

Prompt output

Poster key visual for a summer night electronic music festival,
silhouetted crowd with raised hands, magenta and cyan stage haze,
long-exposure light trails, high contrast, visible grain, wide empty
band across the upper third reserved for the festival name, flat
graphic composition, 2:3

Do not ask the model to render the festival name. Reserve a band for it and set the type in a design tool afterwards.

From idea to prompt

Shape subject, setting, composition, lighting, material, mood, and constraints before you generate.

Prompt patterns from real work

Study public creations by model, category, and tag so your next prompt starts from evidence instead of guesswork.

Clean handoff to creation

Move from prompt research into the Studio without changing the existing login, plan, or credit behavior.

A practical prompt workflow

  4. 04

    Generate, save the useful result, and refine the prompt for the next run.

Which image model to run the prompt on

Credits shown are per image at the listed resolution. The amount actually deducted at generation time is authoritative.

Where image prompts usually go wrong

Every run looks completely different

The prompt is probably a pile of adjectives. Lead with one concrete subject sentence, then add style, light and camera as separate clauses, and change one clause per run.

Text inside the image comes out garbled

Reserve empty space for the copy and set the type afterwards, or move that job to GPT Image 2, which handles readable text better than the illustration-oriented models.

The aspect ratio in the prompt is ignored

The resolution and ratio selector next to the generate button is authoritative and also drives the credit cost. Set it there, and keep the ratio in the prompt only as a hint.

A prompt that worked yesterday stopped working

Save the exact prompt text with the model and resolution you used. Different models read the same words differently, so a prompt is only reproducible together with its model.

Browsing and copying public gallery prompts is open to everyone. Generating requires a signed-in account: reference images you upload are stored by Genvizu so the model can read them, results are kept in your generation history, and credits are deducted under the existing plan and credit rules.

Questions people ask

Is the AI prompt generator free to use?

Browsing and copying prompts from the public gallery costs nothing and does not need an account. Generating an image spends credits from your Genvizu balance, from 1 credit for a Z-Image draft to 23 for a Midjourney 8.2 run; the exact cost appears on the generate button first.

Which image models can I generate with?

GPT Image 2, Nano Banana 2 and Nano Banana 2 Lite, Seedream 5.0 and 5.0 Pro, FLUX.2 and FLUX.2 Pro, Midjourney 8.1 and 8.2, Grok Image 2 and Z-Image. Resolution tiers and credit costs are listed on the model pricing page.

Can I reuse a prompt I found in the gallery?

Yes. Public gallery pages show the prompt, the model and, where the source is known, the original creator. Copy the structure, replace the subject with your own, and the result is a new image rather than a copy.
