+title: What is LlamaIndex?
+description: LlamaIndex is a framework for building LLM-powered applications.
+---
+
+import {
+  SiGithub,
+  SiNpm,
+  SiX,
+  SiDiscord,
+} from "@icons-pack/react-simple-icons";
+import { CodeBlock, Pre } from "fumadocs-ui/components/codeblock";
+import { Tab, Tabs } from "fumadocs-ui/components/tabs";
+
+LlamaIndex helps you ingest, structure, and access private or domain-specific data. It's available [as a Python package](https://docs.llamaindex.ai/en/stable/) and in TypeScript (this package).
+
+LlamaIndex.TS offers the core features of LlamaIndex for JS Runtime-agnostic (Node.js, Deno, and Bun) applications.
+
+## 🚀 Why LlamaIndex.TS?
+
+LLMs offer a natural language interface between humans and inferred data. Widely available models come pre-trained on huge amounts of publicly available data, from Wikipedia and mailing lists to textbooks and source code.
+
+Applications built on top of LLMs often require augmenting these models with private or domain-specific data. That data is often distributed across siloed applications and data stores. It's behind APIs, in SQL databases, or trapped in PDFs and slide decks.
+
+LlamaIndex.TS helps you unlock that data and then build powerful applications with it.
+
+## 🦙 What is LlamaIndex for?
+
+LlamaIndex.TS handles several major use cases:
+
+- **Structured Data Extraction**: turning complex, unstructured and semi-structured data into uniform, programmatically accessible formats.
+- **Retrieval-Augmented Generation (RAG)**: answering queries across your internal data by providing LLMs with up-to-date, semantically relevant context including Question and Answer systems and chat bots.
+- **Autonomous Agents**: building software that is capable of intelligently selecting and using tools to accomplish tasks in an interactive, unsupervised manner.
+
+## 👨‍👩‍👧‍👦 Who is LlamaIndex for?
+
+LlamaIndex targets the "AI Engineer": developers building software in any domain that can be enhanced by LLM-powered functionality, without needing to be an expert in machine learning or natural language processing.
+
+Our high-level API allows beginner users to use LlamaIndex.TS to ingest, index, and query their data in just a few lines of code.
+
+For more complex applications, our lower-level APIs allow advanced users to customize and extend any module—data connectors, indices, retrievers, and query engines, to fit their needs.
+
+## Getting Started
+
+<Tabs items={["npm", "yarn", "pnpm"]}>
+  <Tab value="npm">

+
+Our documentation includes [Installation Instructions](./getting_started/installation.mdx) and a [Starter Tutorial](./getting_started/starter_tutorial/retrieval_augmented_generation.mdx) to build your first application.
+
+Once you're up and running, [High-Level Concepts](./getting_started/concepts.md) has an overview of LlamaIndex's modular architecture. For more hands-on practical examples, look through our Examples section on the sidebar.
