About This Workflow
Overview
This n8n workflow is designed to create a robust system for backing up and processing your weekly notes. It begins with a Webhook Trigger that initiates the process, likely when new notes are ready to be backed up. The incoming text data is then segmented into smaller pieces using the Text Splitter node, which is crucial for managing larger documents. These chunks are converted into numerical representations (embeddings) using the Embeddings node (Cohere in this case) and then stored in a vector database (Weaviate) for efficient retrieval and analysis. A Weaviate Query and Vector Tool are employed to access this stored information. The core logic resides in the RAG Agent, which utilizes a Chat Model (OpenAI) and Window Memory to process the input and query results. Finally, the outcome is logged to a Google Sheet via the Append Sheet node, and any errors encountered during the execution are sent as alerts to Slack using the Slack Alert node.
Key Features
- Automated weekly notes backup triggered via webhook.
- Intelligent text chunking and embedding for efficient data processing.
- Vector storage (Weaviate) for persistent and searchable note backups.
- RAG Agent for contextual understanding and processing of notes.
- Google Sheets integration for logging backup status.
- Slack notifications for error alerting.
How To Use
- Configure Webhook Trigger: Set up the
Webhook Triggerto receive data whenever new weekly notes are ready for backup. Configure thepathto your preference. - Set up Text Splitting: Adjust the
chunkSizeandchunkOverlapparameters in theText Splitternode to optimize how your notes are segmented. - Configure Embeddings: Ensure your Cohere API credentials are set up for the
Embeddingsnode. Themodelis set toembed-english-v3.0. - Set up Weaviate: Configure your Weaviate credentials and
indexNamein both theWeaviate InsertandWeaviate Querynodes. - Configure Chat Model and RAG Agent: Set up your OpenAI API credentials for the
Chat Modelnode. TheRAG Agentis pre-configured to use theChat ModelandVector Tool. - Configure Google Sheets: Set up your Google Sheets credentials and specify the
SHEET_IDandLogsheet name in theAppend Sheetnode. - Configure Slack Alert: Set up your Slack API credentials in the
Slack Alertnode to receive error notifications.
