<h2>About this course</h2>
<p><a href="/topics/langchain">LangChain</a> Academy is the official learning hub from LangChain, the leading framework for building applications with <a href="/topics/llm">large language models</a>. This free course walks you through the fundamentals of LangChain and LangGraph, equipping you to build intelligent, agentic applications that can reason, plan, and act autonomously. Whether you're starting fresh or leveling up, this is where thousands of <a href="/for/developers">developers</a> are learning to harness the power of modern AI.</p>

<h2>What you'll learn</h2>
<ul>
<li>Core concepts of LangChain: chains, agents, and memory systems for LLM applications</li>
<li>How to build agentic applications that can make decisions and take actions</li>
<li>Introduction to LangGraph: orchestrating multi-step workflows and complex reasoning</li>
<li><a href="/topics/prompt-engineering">Prompt engineering</a> best practices within the LangChain ecosystem</li>
<li>Integrating external APIs and tools into your LLM applications</li>
<li>Building retrieval-augmented generation (<a href="/topics/rag">RAG</a>) systems for context-aware responses</li>
<li>Debugging, testing, and deploying LangChain applications in production</li>
</ul>

<h2>Who this is for</h2>
<p>If you're a developer, student, or aspiring AI engineer who wants hands-on experience building real AI applications, this course is for you. No deep machine learning background required—just curiosity and basic Python knowledge.</p>
<ul>
<li>Software engineers — master the practical frameworks powering production AI systems at startups and enterprises</li>
<li><a href="/for/students">Students</a> and freshers — build portfolio projects with cutting-edge tools to stand out in AI-focused job interviews</li>
<li>Product <a href="/for/managers">managers</a> and non-technical founders — understand what's technically feasible when scoping AI features</li>
</ul>

<h2>Prerequisites</h2>
<p>Basic familiarity with Python and how APIs work. You don't need to know machine learning theory or advanced math—just comfort reading and writing code, and curiosity about how LLMs actually work in practice.</p>

<h2>Why this matters for Indian learners</h2>
<p>AI is reshaping India's tech hiring landscape. Companies from Bangalore startups (AI labs, fintech, SaaS) to Tier-1 tech firms in Mumbai and Pune are urgently hiring engineers who can build with modern AI frameworks. LangChain skills are in high demand—engineers proficient in agentic AI command salaries 20–40% above traditional backend roles. This free course gives you a direct path to that premium segment without the gatekeeping of expensive bootcamps.</p>

<h2>Frequently asked questions</h2>
<h3>Is this course really free?</h3>
