Launch Week: assistant-ui goes multi-platform

This week, we're shipping one major feature every day. The theme: assistant-ui everywhere.

For two years, assistant-ui has been the go-to library for building AI chat on the web. Starting this week, that changes. Same runtime, same adapters, same developer experience — now on every platform your users are.

Day 1 — React Native

Build AI chat for iOS and Android.

We're launching @assistant-ui/react-native — native React Native bindings that bring the full assistant-ui experience to mobile.

Everything you know from the web version carries over:

• Same runtime, same adapters. Your ChatModelAdapter, AI SDK integration, or LangGraph setup works out of the box. No rewrites.
• Native primitives. View, Pressable, Text, FlatList — not web views, not wrappers. Real native components.
• Full feature set. Streaming, tool calls, message branching, thread management, attachments — all there.

Get started in one command:

npx assistant-ui@latest create --example with-expo my-chat-app

Or add it to an existing Expo project:

npx expo install @assistant-ui/react-native @assistant-ui/react-ai-sdk

The API mirrors the web version closely. If you've built with @assistant-ui/react, you already know how to use it.

Day 2 — React Ink (Terminal UI)

Build AI chat for the terminal.

We're launching @assistant-ui/react-ink — terminal UI bindings powered by Ink, the React renderer for CLIs.

Build rich, interactive AI chat interfaces that run in any terminal:

• Composable primitives. ThreadRoot, ComposerInput, MessageContent — the same component model, adapted for the terminal.
• Markdown rendering. Ship with @assistant-ui/react-ink-markdown for formatted headings, code blocks with syntax highlighting, tables, and lists — all in your terminal.
• Tool calls with live feedback. Built-in ToolFallback component shows spinners and formatted JSON output while tools execute.
• Shared backend. Same adapters, same runtime core. Switch platforms without touching your backend code.

Get started:

npx assistant-ui@latest create --ink my-chat-app

Day 3 — Assistant Cloud Redesign

A new dashboard for managing your AI assistants at scale.

We've completely redesigned Assistant Cloud — the hosted backend for assistant-ui. Thread persistence, analytics, user management, and more — all in one place.

What is Assistant Cloud?

Assistant Cloud gives your assistant-ui app a production-ready backend. Drop in a few lines of config and get:

• Thread persistence. Conversations survive page refreshes. Users can pick up where they left off.
• Thread list. A ChatGPT-style sidebar, powered by your data — no extra backend work.
• Auto-generated titles. Every thread gets a title, automatically.
• User authorization. Works with Clerk, Auth0, Supabase, Firebase, or anonymous mode for demos.

What's new in the redesign

The new dashboard at cloud.assistant-ui.com is a full control center for your AI deployments:

• Analytics dashboard. Total cost, token usage, run count, average duration — with model distribution charts and usage trends over time.
• Thread browser. Search and inspect every conversation. View full message history, metadata, and timestamps.
• User analytics. Per-user metrics: runs, threads created, tokens consumed, costs incurred.
• Run tracking. Every LLM invocation logged with model, provider, cost, input/output tokens, cached tokens, reasoning tokens, and duration.
• Assistant configuration. Create multiple assistants with different models, system prompts, temperature, and top-p settings.
• LLM provider management. Configure OpenAI, Anthropic, Google, and other providers — with encrypted credential storage.
• API key management. Generate, track, and revoke project API keys.
• Auth rules. Configure JWT validation with JWKS URL, audience, and issuer settings.

Getting started

Add thread persistence to your existing assistant-ui app:

npx assistant-ui@latest cloud

Or integrate directly with the AI SDK using useCloudChat:

npm install assistant-cloud @assistant-ui/cloud-ai-sdk

Works with any assistant-ui runtime — AI SDK, LangGraph, or custom backends. No migration required.

One runtime, every platform

The big picture: assistant-ui is now a universal AI chat framework. Web, mobile, terminal — one codebase for your backend, one set of adapters, one way to register tools. The only thing that changes is the UI layer.

@assistant-ui/react          → Web (React + Radix UI)
@assistant-ui/react-native   → Mobile (React Native)
@assistant-ui/react-ink      → Terminal (Ink)

We'll be updating this post throughout the week as we ship new announcements. Follow @assistant-ui for daily updates or join our Discord for early access.
