How to Use the AI Prompt Enhancer
From a rough idea to three ready-to-paste prompts, in under a minute.
- 1
Paste your idea
Type or paste a short description in any language — “a tiger in the snow” is enough. Pick a scene (portrait, landscape, product, creative) if you already know it, and tick the reference-image box if you plan to edit or restyle an existing photo.
- 2
Enhance
The prompt enhancer rewrites your line into structured English: subject, setting, light and lens, style and mood. You get one version each for Nano Banana Pro, Seedream 4.0, and a third tuned to free drafts or precise edits.
- 3
Copy or generate
Copy any prompt into the generator you already use, or open Ava and let her pick the model, set the parameters, and generate the image after you approve the plan.
What a Prompt Optimizer Actually Changes
An image prompt is four decisions. The enhancer fills in the ones you skipped and phrases them the way each model scores best.
Chủ thể
Who or what the image is about, with one detail that makes it specific rather than generic.
a Siberian tiger mid-stride, frost on its whiskers
Bối cảnh
Where it happens and what surrounds the subject — the background does half the storytelling.
a birch forest after fresh snowfall, pale winter sun low behind the trees
Light & lens
How it is lit and how it is shot. This is what separates a photograph from a render.
backlit rim light, 200mm telephoto, shallow depth of field
Style & mood
The finish and the feeling: photoreal, illustrated, painted, 3D — plus the emotional register.
wildlife documentary photography, cold muted palette, quiet tension
a tiger in the snow
a Siberian tiger walking through a snow-covered birch forest, frost on its whiskers, low winter sun backlighting the fur, 200mm telephoto, shallow depth of field, wildlife documentary photography, cold muted palette
The original has a subject and a location and nothing else. The enhanced prompt adds a moment (walking), a light source, a lens, and a genre — the four things the model was otherwise guessing.
coffee shop logo, minimal
flat vector logo mark for an independent coffee roaster, a single continuous line forming both a coffee bean and a rising sun, black on warm cream, generous negative space, no text
“Minimal” means ten different things. Naming the technique (flat vector, single line), the concept (bean + sun), the palette, and the composition rule turns a vibe into a brief a model can execute.
make the sky more dramatic
replace the overcast sky with towering cumulonimbus clouds lit orange from below by sunset, keep the buildings, people, and foreground exactly as they are, match the new light direction on rooftops
Editing prompts need two lists: what changes and what must not. The enhanced version names the replacement, protects everything else, and asks for the lighting to stay consistent — which is how edit models avoid drifting the whole frame.
Common prompt mistakes
- Stacking quality words. “8k, ultra detailed, masterpiece, best quality” came from older models and does almost nothing on current engines — it spends prompt budget without changing the image.
- Describing what you do not want. Most image models read “no hands in frame” as “hands in frame”. Describe the frame you do want instead.
- Using one prompt for every model. Nano Banana Pro rewards fusion and consistency language; Seedream 4.0 rewards resolution and texture language; an edit model needs explicit change/keep instructions. That is why this tool returns three prompts, not one.
- Writing a paragraph before you have a draft. Generate a cheap draft first (Z Image Turbo is free), see what the model got wrong, then spend words fixing exactly that.
- Forgetting the lens and light. A subject with no lighting or camera direction comes out as a flat render; two words — “window light, 50mm” — fix it.

Câu hỏi thường gặp
What is a prompt enhancer?
A prompt enhancer (or prompt optimizer) takes a short, rough description and rewrites it into the structured, specific prompt that image models respond to best — adding the subject detail, setting, lighting, lens, and style that most people leave out. This one goes a step further and produces a separate version for each model, because the same words do not score the same everywhere.
Does it work for Midjourney, DALL·E, or Flux prompts too?
Yes. The enhanced prompts are plain English with comma-separated descriptors, which is what those generators expect. Copy any card and paste it anywhere. The model-specific tuning is aimed at our lineup, but the structure — subject, setting, light and lens, style — improves results on every current image model.
Why do I get three different prompts instead of one?
Because models speak different dialects. Nano Banana Pro rewards fusion, consistency, and identity language; Seedream 4.0 rewards resolution, texture, and professional-lighting language; Z Image Turbo wants a clear, efficient prompt for fast drafts; Qwen Image Edit Plus needs explicit “change this, keep that” instructions. One generic prompt leaves each model guessing at the parts it cares about.
Is the AI prompt enhancer free?
Completely — no account, no credits, no watermark on the text. There is a fair-use rate limit per visitor so the tool stays fast for everyone. If you hit it, wait a minute or continue in Ava, where enhancement is part of every conversation.
Can I enhance prompts written in other languages?
Yes. Write your idea in any of the 27 languages CreateVision AI supports; the enhancer understands it and returns the prompt in English, which is the language current image models score best on. If you need the result in another language, ask Ava — she replies in the language you write in.
How is this different from Ava?
This page is a single step: idea in, prompts out, you decide what to do next. Ava is the full workflow — she enhances the prompt, chooses the model with public arena rankings to back the choice, sets ratio and quality, shows you the plan with its credit cost, and generates after you approve. Use the enhancer when you want the words; use Ava when you want the image.
