Ask for a day in San Francisco and get a routed map, photographs, and an editable itinerary instead of a wall of text. Open Intelligent UI recreates the interactive answers introduced in ChatGPT, with the model streaming a layout that the app renders live from a library of 55 components. A request for a phone comparison returns product cards and a side-by-side table, a money question returns sliders that recalculate loans and savings as they move, and a language question returns flip cards followed by a scored quiz. Dashboards offer date-range switches, KPI cards, area charts, ranked source bars, and sortable page tables, and maps add category filters, pins, expandable stops, and street routes. Fifty-nine built-in functions let each answer compute with its own state, so splits, schedules, and unit conversions update without another model call. Chat history keeps earlier answers, light and dark themes are one click away, and suggestion tiles start common requests. A development gallery shows worked examples, including a bike assembly guide, a retirement calculator, and a small arcade game, all without calling a model. Models connect through OpenUI Cloud, any OpenAI-compatible endpoint, or local Ollama, so keys and data stay in your control. Product teams, designers, and developers get a working reference for generative interfaces.
