Logo

## 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. ``` For the full 7-step prompt framework and model comparison, load `ai-generation.md`. --- ## Decision Tree | Situation | Load | |-----------|------| | AI generation (Nano Banana, GPT Image, prompts, iOS icons) | `ai-generation.md` | | Logo types (wordmark, symbol, combo, emblem) | `types.md` | | Design process with a human designer | `process.md` | | File formats and export requirements | `formats.md` | | DIY without AI (templates, Canva) | `diy.md` | | Hiring designers or agencies | `hiring.md` | --- ## 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 --- ## When to Load More | Situation | Reference | |-----------|-----------| | Full prompt frameworks, model comparison, iOS icons | `ai-generation.md` | | Wordmark vs symbol vs emblem decisions | `types.md` | | Working with designers, brief templates | `process.md` | | SVG, PNG, favicon, size requirements | `formats.md` | | Track what works, learn from iterations | `feedback.md` |
