## Which one do I need?
**You already have an agent.** Connect it to the channels your customers use — Slack, iMessage, MS Teams, WhatsApp — with the AI SDK. **You're notifying users.** Build workflows that send the right message to the right subscriber — Inbox, email, and Slack.

## Choose your path Novu Connect gives your AI agent a communication layer. It receives provider webhooks, normalizes messages, resolves identity, preserves conversation state, and delivers replies back to the original thread — so an agent you've already built can hold real conversations over Slack, iMessage, MS Teams, and WhatsApp. Connect an agent built with the AI SDK and send your first message. Understand the infrastructure layer between messaging providers and agent intelligence. Bring your own LLM, tools, runtime, and business logic. Inspect agent conversations, message history, participants, and provider context. Novu Notify helps you send the right message to the right subscriber on the right channel. Define workflows, trigger events, render content, respect preferences, and inspect delivery. Add the Novu Inbox to a React application and send your first notification. Learn how workflows model notification logic across channels and steps. Embed a real-time notification feed that subscribers can read, archive, snooze, and configure. Connect providers for email and Slack delivery. ## Build with your stack Connect an agent built with the AI SDK to Novu Connect. Add Inbox and notification UI to React, JavaScript, and React Native apps. Trigger notifications and call the API from TypeScript, Python, Go, PHP, .NET, Java, Kotlin, Laravel, and Ruby. Explore Novu REST APIs for events, subscribers, workflows, integrations, messages, and more. Build notification workflows as code with the Novu Framework. ## Community Star Novu, inspect the source, and contribute to the project. Ask questions and build with the Novu community. Follow product updates, SDK releases, and improvements across Connect and Notify.
