# x70 Agentic UI > Agentic UI is a playful single-user experiment where an AI Agent can answer with concise text, an interactive React interface, or both. It uses the X70 public-site design system. Important notes: - **Experience:** Public, single-user, and ephemeral. Refreshing or leaving `/chat` ends the Session. - **Rendering boundary:** UI Replies are validated component trees drawn from a finite React catalog. The site does not inject model-authored HTML, CSS, or JavaScript. - **Interaction:** Controls in the newest UI Reply submit structured values as the next turn. Older UI Replies remain visible but become read-only. - **Model:** OpenRouter `nvidia/nemotron-3-nano-30b-a3b:free`. - **Access:** No account is required. Chat requests are rate-limited. - **Titles:** Homepage uses `x70 · Agentic UI`; subpages use `{Page Name} · Agentic UI`. ## Pages - [Home](/): Introduces the experiment with live interface examples. - [Features](/features): Demonstrates interactive forms, choices, dashboards, tables, and charts without screenshots. - [Chat](/chat): The ephemeral Agentic UI Playground. ## Technical shape - Next.js 16 and React 19. - X70 template header, footer, theme, motion, typography, and section geometry. - Vercel AI SDK through an OpenRouter OpenAI-compatible provider. - Zod schema validation plus an explicit React Component Catalog. - Optional Upstash Redis request admission in production. ## Ecosystem sibling sites - **x70 App** ([x70.one](https://x70.one)): Web agency and product engineering. - **x70 Apps** ([apps.x70.one](https://apps.x70.one)): Collection of modern native apps from X70. - **GitGrid** ([gitgrid.x70.one](https://gitgrid.x70.one)): Browser-local preview for planning a steadier GitHub contribution rhythm within a dedicated private-repository boundary. - **x70 Links** ([links.x70.one](https://links.x70.one)): Directory of X70 properties. - **Developer Portfolio** ([me.x70.one](https://me.x70.one)): Daniel Ensminger's work and writing. - **Design Guidelines** ([design.x70.one](https://design.x70.one)): Canonical X70 design system and brand assets. - **Browser Tools** ([tools.x70.one](https://tools.x70.one)): Privacy-first browser utilities. - **Boop** ([boop.x70.one](https://boop.x70.one)): Support and policy site for Boop.
