How to Build Your Own RAG App Using Claude (No Code Required)
Ever seen those AI apps that seem to know everything about a specific topic, whether it's research papers, an author's work, or a podcast series? They're called RAG (Retrieval-Augmented Generation) apps, and they're pretty powerful. But here's the thing - you don't need to build one from scratch. Claude can help you create your own personal RAG app in minutes.
Why Use Claude for RAG?
- More cost-effective than building custom
- Significantly faster to set up
- No coding required
- Powerful retrieval capabilities
Quick Tutorial: Building a Sleep Optimization RAG
Let's walk through creating a RAG app using Andrew Huberman's sleep podcast as an example.
Step 1: Create a New Project
- Navigate to Claude's project section
- Name your project (e.g., "Sleep Optimization")
- Define your goal clearly
Step 2: Add Your Knowledge Base
- Get your content (in our case, the podcast transcript)
- Click "Add to project knowledge"
- Either upload files or paste text content
- Note: A 90-minute podcast transcript only uses about 14% of available capacity
Step 3: Start Interacting
Once your content is uploaded, you can immediately start asking questions. Claude will search through the uploaded content to provide relevant, accurate answers based on your source material.
Pro Tip: Custom Styles
Want to make it even better? Create a custom style using examples from your source material. This will make Claude respond in a tone that matches your content's voice.
Use Cases
You can use this for:
- Research paper analysis
- Podcast knowledge bases
- Documentation
- Personal knowledge management
- Author studies
- Course material synthesis
Alternative: Building Your Own
If you do want to build a custom RAG app from scratch, check out my video on simple RAG stacks. But for most use cases, Claude's project feature provides everything you need without the complexity.
