** 3 AI workflows
*** 1. RAG pipeline & chatbot
**** tools
- pinecone :: vector database
- google drive :: data storage
- google docs ::

** Workflow #1 - Rag Pipeline and Chatbot
*** RAG
- stands for :: retrieval, augmented, generation
- looks inside database for the answer

**** Vector Database
- multidimensional graph of points
- vector is placed based on meaning of vector
  - ie, wolf and dog will be close
  - banana, apple will be close

**** how it works
- we have a document
- break it into chunks
- run it through an 'embeddings model'
  - this puts the chunks into a vector model

**** Query
- run the query through the embeddings model
- see where it lands in vectors, grabs back the nearest 4 or 5 vectors and returns it to us

*** process
- our trigger is any changes in folder on google drive

*** get Google Drive Credentials
