From AI basics to building agents — here are the exact free courses, from OpenAI, Anthropic, Microsoft, and Harvard, that will take you from overwhelmed to job-ready.

More than 75% of people in India are still not using AI effectively — not because the tools are hard, but because no one showed them the right starting point. These 7 courses fix exactly that.


     1. CS50X 2025 — Artificial Intelligence

  The best starting point for anyone new to AI. Harvard's CS50 recently released this one-hour video that gives you a clear, jargon-free overview of the entire AI landscape — what it is, how it's changing the world, and what's actually happening inside these systems.


     2. Introduction to Prompt Engineering

  Prompt engineering is the most immediately useful AI skill you can learn — and OpenAI's free academy has the best course for it. It takes you from writing mediocre prompts to crafting structured, reliable ones with real examples at every step. A good prompt always includes context, role, and a clear expectation.


     3. How to Use LLMs Effectively

  This 2-hour video by Andrej Karpathy — one of the greatest AI educators alive — is the definitive guide to getting the most out of AI tools. Not just ChatGPT, but the full ecosystem. If you only watch one video on this list, make it this one.


     4. Vibe Coding with Replit

  You don't need to be a developer to build real apps anymore. This course teaches you how to use AI to go from idea to a working, deployed application — using Replit as your co-builder. Perfect if you want to launch landing pages, portfolio sites, or product prototypes without writing a single line of code yourself.


     5. Claude Code in Action

  Built by Anthropic — the company behind Claude — this 1-hour course is the fastest way for developers to start using AI as a real coding assistant. Claude Code is one of the most powerful coding tools available today, and this course gives you the complete foundation to use it effectively.


     6. Generative AI for Beginners

  Microsoft's comprehensive GenAI course is the best all-rounder on this list. It starts with LLM basics and takes you all the way through to RAG, AI agents, and fine-tuning — all in one structured package. Ideal if you want a single course that covers the full breadth of generative AI development.


     7. Build and Sell AI Agents with n8n

  AI agents are the biggest career and business opportunity in AI right now. Companies are actively paying to automate their workflows — and this 8-hour course teaches you to build exactly that using n8n's drag-and-drop interface. No coding required, and by the end you'll know how to package and sell these skills as a service.
