What type of RAG pipeline or type of RAG did you implement?

Karthik Kandikonda

@tomas_baron Hey! Thanks for stopping by! Currently, it is a straightforward RAG implementation, which LlamaIndex refers to as 'naive RAG.' Documents are chunked and stored in a vector database for retrieval, so nothing fancy just yet. I wanted to flesh out the system first before adding more advanced retrieval techniques. I would love to hear your thoughts on LiquidIndex. Do you have any suggestions or features you would like to see?

@tomas_baron @karthik_kandikonda Great starting point - checkout GraphRAG and LightRAG (for better scores)

@tomas_baron @aiparth Will do! I was thinking of letting users select the type of RAG and their preferred vector database when creating a project. What are your thoughts on that? Or do you think there are other features that should take priority?


Thank you very much for the feedback and support!

Hey Product Hunt! 🚀


I'm super excited to be launching here for the first time! I’ve shared this project a couple of times on X (Twitter), but some friends told me about Product Hunt, so here I am!


I started working on this back in October 2024 because I saw the potential in cloud-based RAG—but most tools I found were either too complex, didn’t integrate well with other systems, or required too much setup. And honestly, why should you spend extra time building RAG when you could be focusing on your actual product?


That’s why I built this—to give developers high-quality AI search that just works, so they can spend more time building and less time side questing.


With this launch, you can:
Upload and connect your documents via file upload (Google Drive support is pending approval)
Query across ALL your data effortlessly— with just one API call
Get direct sources for every response, so you know exactly where the information came from


This is just the beginning, and I’d love to hear your thoughts! Your feedback means the world to me, and I can't wait to see how people use this.


Would love to know—what’s your biggest frustration when working with document-based AI?


Thanks for checking it out! 🚀
