How It Works
LetzAI streamlines the traditionally complex process of custom AI model creation into an accessible workflow designed for creators of all technical backgrounds. Users begin by selecting their desired model type (person, product, or style) and uploading 10-20 high-quality training images that represent the subject or aesthetic they wish the AI to learn. The platform’s AI training engine processes these images using advanced machine learning techniques, typically completing model training within hours while sending email notifications upon completion. Once trained, users activate their custom models and can immediately begin generating images by incorporating their model tags into natural language prompts, with the ability to blend multiple models for unique creative combinations. The platform’s community features enable sharing trained models publicly or keeping them private, while integrated editing tools allow for post-generation refinement through inpainting, outpainting, and upscaling capabilities.
Use Cases
LetzAI addresses diverse creative and commercial scenarios where personalized AI generation provides significant value over generic alternatives:
- Brand identity and marketing asset creation: Companies can train AI models on their specific products, brand aesthetics, and visual guidelines to generate consistent marketing materials, social media content, and advertising visuals that maintain brand coherence across all touchpoints and campaigns.
- Artist style exploration and portfolio expansion: Visual artists can create AI models trained on their existing artwork to explore variations, experiment with new compositions, and rapidly prototype concepts while maintaining their distinctive artistic voice and style consistency.
- Product visualization and e-commerce content: Retailers and manufacturers can generate diverse product imagery, lifestyle shots, and contextual applications by training models on their product catalogs, enabling cost-effective content creation for multiple marketing channels without extensive photography sessions.
- Personal creative projects and social content: Individual creators can develop AI representations of themselves, family members, or personal aesthetic preferences to create unique social media content, personalized artwork, and creative expressions that reflect their individual identity and style.
