## 📖 About This Course
This course is part of Decoding AI's open-source series, teaching you how to build production-ready GenAI systems using LLMs, RAG, agents and LLMOps.
**The Second Brain AI Assistant** course contains **6 modules** that will teach you how to build an **advanced RAG and LLM system using LLMOps and ML systems best practices**. You'll learn to build an end-to-end AI assistant that chats with your Second Brain - your personal knowledge base of notes, resources, and storage.
By the end of this course, you'll be able to architect and implement a production-ready agentic RAG and LLM system from scratch.
### So What Is the Second Brain AI Assistant?
The Second Brain, a concept by Tiago Forte, is your personal knowledge base of notes, ideas, and resources. Our AI Assistant leverages this knowledge to answer questions, summarize documents, and provide insights.
Imagine asking your AI Assistant to recommend agent courses, list top PDF parsing tools, or summarize LLM optimization methods - all based on your research, without manually searching through notes.
While we use Notion for this course, the code is adaptable to other sources like Google Drive or Calendar. We'll provide our curated AI/ML resource list from Notion, covering GenAI, LLMs, RAG, MLOps, and more. **No Notion account needed** - but if you want to use yours, our flexible pipeline supports any Notion database.

### What You'll Do:
- Build an agentic RAG system powered by your Second Brain
- Design production-ready LLM architectures
- Apply LLMOps and software engineering best practices
- Fine-tune and deploy LLMs
- Use industry tools: OpenAI, Hugging Face, MongoDB, ZenML, Opik, Comet, Unsloth, and more
After completing this course, you'll have access to your own Second Brain AI assistant, as seen in the video below:
