About This Workflow
Overview
This n8n workflow is designed to automate the process of taking images from Unsplash and preparing them for use on Pinterest. It starts with a Webhook Trigger which can be initiated by an external service or manual call.
The incoming data, likely image metadata or URLs from Unsplash, is then processed by a Text Splitter node from the Langchain integration. This prepares the text for embedding. An Embeddings node (Cohere) generates vector representations of the text, which are then stored in Supabase using the Supabase Insert node. Simultaneously, a Supabase Query node is available for retrieving similar items, suggesting a potential for future enhancements or different use cases.
For AI-powered interactions, the workflow includes a Vector Tool which accesses the Supabase vector store, Window Memory for context, and a Chat Model (OpenAI). These components feed into a RAG Agent which can process and define content based on the retrieved information. The output of the RAG Agent is then logged to a Google Sheet via the Append Sheet node. In case of errors, a Slack Alert node is configured to notify a designated channel.
Key Features
- Webhook-based trigger for initiating the automation.
- Text splitting for efficient AI processing.
- AI-powered text embedding using Cohere.
- Vector data storage and retrieval with Supabase.
- RAG (Retrieval-Augmented Generation) agent for intelligent content processing.
- Logging of process status to Google Sheets.
- Error alerting via Slack.
How To Use
- Set up a
Webhook Triggerand obtain its URL. - Configure the
Text SplitterandEmbeddingsnodes with your desired parameters. - Connect your Supabase account and specify the index name for the
Supabase InsertandSupabase Querynodes. - Set up your OpenAI and Cohere API credentials.
- Configure the
RAG Agentwith the appropriate prompt and system message. - Link your Google Sheets account and specify the Sheet ID and Log sheet name for the
Append Sheetnode. - Configure the
Slack Alertnode with your Slack API credentials and channel for error notifications. - Trigger the webhook with appropriate Unsplash image data to start the automation.
