A: Great question!
Currently, Release0 does not offer a built-in RAG (Retrieval-Augmented Generation) system. It functions as a no-code chatbot and workflow automation builder, where you control logic, prompts, and integrations including AI integrations.

However, you can:
- Build structured prompt flows using variables and user input.
- Integrate external RAG services (like ChatNode, OpenRouter, or your own API) via webhooks or our HTTP Request block.
- Use document-based context if your external RAG provider supports it (e.g., limiting responses to a PDF or website content).

So if you already have a knowledge base system (with vector search, etc.), you can plug it in seamlessly. As an example, if you use OpenAI, just create your "Assistant" at https://platform.openai.com/assistants upload PDFs with your knowledge base or point to websites with the information to train your assistant. Then from Release0 use your API key to connect R0 with OpenAI and from the R0 OpenAI block select the "Ask Assistant" option from the several integration options. You will find your newly created and trained Assistant there.
Then just loop it with the agent user prompt. Now your agent will use your knowledge base to reply.
This gives you RAG flexibility without vendor lock-in, and keeps your token usage optimized based on your own infrastructure.
