How It Works
What Makes This Different
- Intent Analysis -- Understands what you actually need (blog header? app icon? product shot?)
- Domain Expertise -- Selects the right creative lens (Cinema, Product, Portrait, Editorial, UI, Logo, Landscape, Infographic, Abstract)
- 5-Component Prompt Formula -- Constructs prompts with Subject + Action + Location/Context + Composition + Style (includes lighting)
- Prompt Adaptation -- Translates patterns from a 2,500+ curated prompt database to Gemini's natural language format
- Post-Processing -- Crops, removes backgrounds, converts formats, resizes for platforms
- Batch Variations -- Generates N variations rotating different components
- Session Consistency -- Maintains character/style across multi-turn conversations
- 4K Resolution Output -- Up to 4096×4096 with
imageSizecontrol - 14 Aspect Ratios -- Including ultra-wide 21:9 for cinematic compositions
