@LangChainAIBuild stateful conversational AI agents with LangGraph and assistant-ui.
@js_craft_hqA huge shoutout to @simonfarshid for the cool stuff he makes at assistant-ui
@adamsilvermanassistant-ui powered by LangGraph! It is awesome.
@hwchase17Pleasure to work with Simon… bring streaming, gen UI, and human-in-the-loop with LangGraph Cloud + assistant-ui.
@neondatabaseConversations and streaming AI output are powered by @assistantui. It renders the chat interface and stores threads in Assistant UI Cloud so sessions persist across refreshes and context builds over time.
@ycombinator@assistantui is an open-source TypeScript/React library for AI chat. It brings a ChatGPT-like UI directly into your app.
@viratttMy favorite financial assistant is assistant-ui… fully open source… powerful starter tools… integrates with LangSmith and LangGraph.
@hungrytrtlassistant-ui… Could save days of UI work.
@keithschachtA great set of pre-built react components for building chatbot experiences.
@HowardBGilStop building chat interfaces yourself… Just install assistant-ui and you’re done.
@replyingaleksassistant-ui goated 🐐🐐
@yagudaevReact chat ui so you can focus on your agent logic. Can't wait to try it.
@voltagent_devWe just added Assistant UI support to VoltAgent. Streaming, tools, memory all work out of the box.
The UX of ChatGPT in your own app.
