In this video, I break down the essential concepts of inserting data into a vector database, including embeddings, loading, metadata, and text splitting. These are critical for creating effective Retrieval-Augmented Generation (RAG) systems and building a strong knowledge base. Using tools like n8n and Pinecone, I’ll guide you step-by-step through practical examples to help you master these foundational skills. Whether you're new to vector databases or looking to improve your AI agent systems, this tutorial is for you!

No way I stumbled on this channel… exactly what I’ve been looking for, nice vid bruh super helpful and consumable man

This is the video I was waiting for, thank you so much!

[jribesc]

Thank you very much. I wanted to ask you a question, which is the best and most recommended vector database, Qdrant, Pinecone or Supabase? I like the Qdrant option for being local, Pinecone for its simplicity and Supabase everyone tells me it is the best, but its free plan does not convince me because my project is small and every week the project is put on pause if not used...

[mateussaviolo]

Bro, which one do you think is better? Supabase or Pinecone?

[jimvh]

Great video! I think that the chunk overlap (at 13:20 in the video) only seems to happen when sentences are not complete. That's what I see happening in your example here. Take a look again and try it out. So it chunks when the sentence is incomplete and uses the last part as first part only then.

[MariushAI]

Do you know how to integrate semantic text splitting into n8n?

[jordig]

quite helpful to see all those options without much sense. Missing chunk and overlap, which are REALLY very important, and update the content...your clicks and moving around made me nervous .... LOL

what is the real value application of this
