About This Workflow
Overview
This workflow provides an automated solution for checking visa requirements for travelers. It leverages a webhook to receive user queries, then uses LangChain nodes to process the information. Text data is split, embedded using Cohere, and stored in a Weaviate vector database for efficient retrieval. When a query comes in, it's embedded and used to query the vector store, with an AI agent (Anthropic) providing the final answer. All interactions and results are logged to a Google Sheet for record-keeping and analysis.
Key Features
- Real-time visa requirement checks via webhook.
- AI-powered information retrieval and response generation.
- Efficient data storage and querying with Weaviate vector database.
- Text splitting and embedding for enhanced AI processing.
- Automatic logging of queries and results to Google Sheets.
How To Use
- Set up the 'Webhook' node with your desired path (e.g.,
visa_requirement_checker). - Configure the 'Splitter' node for text chunking.
- Set up the 'Embeddings' node with your Cohere API credentials.
- Configure the 'Insert' and 'Query' nodes to point to your Weaviate instance and the
visa_requirement_checkerindex. - Set up the 'Chat' node with your Anthropic API credentials.
- Configure the 'Agent' node to use the retrieved tools and memory.
- Set up the 'Sheet' node with your Google Sheets API credentials to log the results.
- Trigger the webhook with user queries about visa requirements.
