description	Generate logos with AI image tools using effective prompt structures, validation loops, and export workflows for App Store icons and brand marks.

Quick Start: AI Logo Generation

Best model for most logos: Nano Banana Pro (Gemini 3 Pro Image)

Basic Prompt Formula

Create a [STYLE] logo featuring [ELEMENT] on [BACKGROUND].
[DESCRIPTION]. The logo should look good at 32px with recognizable shapes.

Example

Create a minimalist logo featuring a geometric mountain peak on white background.
Clean lines, navy blue (#1E3A5A), modern and professional style.
The logo should look good at 32px with recognizable shapes.

Model Quick Reference

Model	Best For
Nano Banana Pro	Overall best, text + icons, App Store icons
GPT Image 1.5	Conversational iteration, natural language
Ideogram	Perfect text rendering
Midjourney v7	Artistic icons only (no text)

iOS App Icons (Liquid Glass)

iOS 26 uses Liquid Glass design. Use this prompt structure:

Create a polished iOS app icon featuring [ELEMENT].
Rounded square with [COLOR] gradient, minimalist white symbol centered.
Soft shadows, glassy depth effect, works at 60px.
The icon represents [APP PURPOSE].

See ai-generation.md for the complete iOS 26 prompt template.

Validation Loop (MANDATORY)

NEVER deliver without visual review. Every AI output must be inspected before sharing.

1. Generate → 2. Look at the actual image → 3. Check for issues → 4. Fix or regenerate → 5. Repeat (max 5-7 attempts)

Common fixes:

• Unwanted padding → Crop
• Elements cut off → Regenerate with "centered composition"
• Text garbled → Use Nano Banana/Ideogram or add manually
• Too complex → Simplify prompt

If 5-7 attempts fail, change model or strategy entirely.

Universal Truths

AI output is a starting point. Every AI logo needs vectorization, cleanup, and manual text refinement. Never use raw output as final.

Test at small sizes early. If it doesn't work at 32px, simplify. Most real-world usage is small.

Text handling varies. Only Nano Banana and Ideogram reliably render text. For Midjourney, generate icon-only.

Simple logos last. Nike, Apple, McDonald's. Complexity dates quickly and fails at small sizes.

Before Finalizing

• Works in black and white
• Readable at 32px (favicon test)
• Vectorized (SVG), not just PNG
• All variants created (horizontal, stacked, icon-only)
• Text manually refined, not AI-generated
• Tested on dark and light backgrounds
