AI Agent Messenger (React)

You've built an AI agent. It can answer questions, call tools, maybe even book flights. Now you need to put a chat window in front of a user — and you do not want to spend three weeks building message bubbles, typing indicators, scroll-to-bottom logic, and the fourteen other small things that make a chat UI feel like a chat UI instead of a form.

@sendbird/ai-agent-messenger-react is Sendbird's React component library for embedding AI agent chat into a web app. It gives you the conversation surface — the message list, the input, the rendering of AI-side messages, the typing state, the scrolling behavior — as React components you drop in and wire up to your agent's backend.

If you're building a customer-facing product where the AI is the interface — a support bot, a shopping assistant, a copilot pinned to the side of a dashboard — this is the kind of package you reach for instead of rolling your own. It handles the parts that are easy to get wrong: message ordering, optimistic updates, keyboard focus, the thousand tiny details that separate a chat that feels alive from one that feels like a form submission.

It's a React library, so it assumes you're already in that world. It's Sendbird-published, so expect it to slot cleanly into a Sendbird backend, though how much works outside that is a question for their docs. And it's a UI layer, not an agent framework — you still bring your own agent logic, your own LLM calls, your own tool routing. This package just gives the conversation a body.

For teams whose agent already works in a terminal and now needs a face, start here instead of from scratch. Pair it with something like Telnyx AI Agent Library if you're also wiring voice or SMS into the same agent.

Install it, drop the messenger into a page, point it at your agent endpoint, and see how much of the ugly part disappears.
