Upload your documents to a **Qdrant** vector store, delete by category when outdated, and power an AI chatbot that answers questions using **only your uploaded data**.\n\nAll chat behavior is configured from a single **`Set Context`** node.\n\n### How it works\n1. **Upload:** Submit a file via the Upload form \u2192 chunks into segments \u2192 embeds with Gemini \u2192 stores in Qdrant tagged by document category.\n2. **Delete:** Submit the Delete form \u2192 removes all vectors for the selected category (use before re-uploading an updated document).\n3. **Chat:** User asks a question \u2192 AI Agent retrieves relevant context from Qdrant \u2192 responds based solely on your uploaded documents.\n\n### Setup\n* [ ] Install community node `n8n-nodes-qdrant` (Settings \u2192 Community Nodes).\n* [ ] Connect **Google Gemini** (`googlePalmApi`) credential to: *Embeddings Google Gemini*, *Embeddings Google Gemini1*, and *Google Gemini Chat Model*.\n* [ ] Connect **Qdrant API** (`qdrantApi`) credential to: *Insert to Vector Store* and *Knowledge Base*.\n* [ ] Connect **Qdrant REST API** (`qdrantRestApi`) credential to: *Delete from Vector Store*.\n* [ ] Edit **Set Context** node: update `bot_name`, `company_name`, and `support_email`.\n* [ ] Set your **Qdrant collection name** in all 3 Qdrant nodes.\n* [ ] Update dropdown options in both Form Triggers to match your document categories.\n* [ ] Activate the workflow.\n\n### Customization\n* Swap Gemini for OpenAI, Claude, or any LangChain-supported model.\n* Replace Qdrant with Pinecone, Supabase pgvector, or Weaviate.\n* Replace Chat Trigger with a Webhook to embed in your own application.\n\n### Requirements\n* n8n 2.9.4+\n* Community node: `n8n-nodes-qdrant`\n* Google Gemini API key\n* Qdrant instance (cloud or self-hosted)\n\n### LICENCE\nShared free of charge.
