AI Prompt Engine v3.0 — Image & Video
Hyperrealistic Image & Video
Prompt Generator
Advanced prompt builder for Midjourney, DALL-E 3, Stable Diffusion, Flux, Nano Banana 2 & Veo 3. Pick a template, tune the parameters, generate.

Nano Banana 2 (Gemini 3.1 Flash Image) prompt rules:
▶ Verb first — the Opening Verb is placed at the very start of the prompt automatically.
▶ Positive framing — describe what you want, not what to avoid (use Negative Prompt field for exclusions).
▶ Tech specs — redundant terms are auto-deduplicated (e.g. 85mm + f/1.4 + prime lens → one clean spec).
▶ Text in image — enclose words in "quotes" and specify font (e.g. "bold white sans-serif").
▶ 4K note — "4K" in prompt affects detail density, not file size. Use the in-app Upscale button for true 4K output.

Veo 3 — Video Model Architecture
▶ Prompt reads like a director's treatment — not a list of tags.
▶ Structure: Shot + Subject + Action + Setting + Lighting + Camera + Motion + Audio
▶ Describe camera movement explicitly — Veo defaults to static if not specified.
▶ Keep prompts 100–150 words. Too short = generic. Too long = confusion.
▶ Dialog in quotes: A woman says, "We have to leave now."
▶ Name a motivated light source — stabilizes shadows across frames.
