   A React and Next.js UI Toolkit for LLMs▲24

   Hey HN, I wanted to share a UI toolkit project I’ve been working on recently, born out of how difficult I found it to build a great UX on top of LLMs, and keep application state in sync. I’ve built: - A React/JS front-end library for conversational interfaces, which makes it super easy to bootstrap AI assistants and ChatGPT style UX: https://github.com/nlkitai/nlux - A set of adapters that simplify integration with AI backends such as LangServe and HuggingFace The library is highly configurable, easy to theme, supports markdown streaming (that was tough to get…

    OpenAI ChatGPT App starter DevXP feels like 2010, I built a better one▲19

The dev feedback loop was pretty terrible. That’s why I built a TypeScript starter that gets you up and running in under a minute. Clone, npm install, npm run dev, paste your ngrok URL into ChatGPT, and you're iterating on widgets with Hot Module Reload…
