Automated Calendar Event Tagging with AI and Vector Stores
detail.loadingPreview
This n8n workflow automatically tags calendar events by leveraging AI and vector store technology. It processes event details through a Webhook Trigger, splits text with Text Splitter, generates embeddings with Embeddings, and stores/queries this data using Weaviate.

About This Workflow
Overview
This n8n workflow is designed to automate the tagging of calendar events. It utilizes a Retrieval-Augmented Generation (RAG) approach by integrating AI models and vector stores. The process begins with a Webhook Trigger receiving calendar event data. This data is then split into manageable chunks using the Text Splitter node. Next, the Embeddings node generates vector representations of the text, which are then inserted into a Weaviate vector database using the Weaviate Insert node. For processing, a Weaviate Query retrieves relevant information, which is then processed by a Vector Tool. This tool, along with Window Memory and a Chat Model, feeds into the RAG Agent. The RAG Agent, acting as the core intelligence, processes the event data and generates appropriate tags. Finally, the results are logged to a Google Sheet via the Append Sheet node, and any errors are reported via Slack Alert. This workflow solves the problem of manual event tagging by providing an intelligent, automated solution.
Key Features
- Webhook Trigger for real-time event data intake.
- Text Splitting for efficient processing of large text inputs.
- OpenAI Embeddings for converting text into numerical vectors.
- Weaviate for storing and retrieving vectorized data.
- RAG Agent for intelligent data processing and tag generation.
- Google Sheets integration for logging and auditing.
- Slack notifications for error alerting.
How To Use
- Set up a Webhook Trigger to receive calendar event data.
- Configure the Text Splitter to appropriately segment your event descriptions.
- Ensure your OpenAI API credentials are set for the Embeddings and Chat Model nodes.
- Set up your Weaviate instance and provide the necessary API credentials.
- Configure the Weaviate Insert and Query nodes with your desired index name (e.g., 'calendar_event_auto-tag').
- Set up your Google Sheets credentials and specify the sheet ID and log sheet name for the Append Sheet node.
- Configure your Slack API credentials for error alerts.
- Trigger the workflow by sending data to the Webhook URL.
