FAQ
What is an n8n RAG AI agent?
An n8n RAG AI agent retrieves relevant information from approved sources before generating an answer. The workflow can connect retrieval, AI, business tools, and escalation rules.
Which content can the RAG chatbot use?
The RAG chatbot can use approved PDFs, documents, FAQs, website pages, Notion, Google Drive, Airtable, or database records when the format and access are supported.
Which vector databases do you support?
I can work with Pinecone, Qdrant, Supabase or another supported vector database after reviewing your data volume and hosting requirements.
Can you use OpenAI Claude or Gemini?
Yes. I can configure the n8n AI agent with a supported OpenAI, Claude, or Gemini model based on your account, use case, and required integrations.
Will answers include sources?
The Standard and Premium packages can return source references or document metadata when the retrieval system and chatbot interface support them.
Can the knowledge base update automatically?
Yes. I can build document ingestion automation that refreshes the vector database on a schedule or supported content event.
Can you connect the RAG agent to my website?
Yes. I can connect the knowledge base chatbot to a supported website interface, API, webhook, or existing chat frontend.
Can the AI customer support agent escalate to a human?
Yes. Standard and Premium can include human escalation when confidence is low, information is missing, or the user requests assistance.
Can you guarantee completely accurate answers?
No AI system can guarantee perfect answers. I reduce risk with approved sources, retrieval rules, prompt constraints, test scenarios, fallback responses, and escalation.
What support is included?
I fix bugs inside the delivered n8n RAG workflow during the package support period. New sources, channels, models, or integrations require a separate offer.
