Gelt

Gelt is an AI-powered platform for designing, building, and iterating on websites, web applications, and interactive prototypes without writing code. It translates natural language specifications, sketches, and content into structured, production-ready front-end experiences. The primary purpose of Gelt is to shorten the path from concept to deployable product while maintaining professional design and code quality standards.

Gelt combines large language models such as Claude 4 Sonnet and GPT-5 with a visual editor to generate clean, responsive layouts, component structures, and UI flows. Users can define pages, components, and behaviors in plain English, then refine them through an intuitive interface that supports versioning, preview, and instant updates. The platform outputs standards-based HTML, CSS, and JavaScript (or modern frameworks, depending on configuration), enabling easy integration with existing backends and APIs. Built-in design systems, reusable components, and automatic responsiveness help ensure consistency across desktop and mobile experiences.
