Automate Voice Tasks to Notion with n8n and AI
detail.loadingPreview
This n8n workflow automatically processes voice tasks received via webhook, enriches them with AI, stores them in Weaviate, and logs the results in Google Sheets. It leverages AI-powered text splitting, embeddings, and agent reasoning to handle and categorize tasks efficiently.

About This Workflow
Overview
This n8n workflow is designed to automate the process of handling voice-based tasks. It begins by receiving task data via a Webhook Trigger. The incoming text is then processed using a Text Splitter and OpenAI Embeddings to prepare it for vector storage in Weaviate. This vector database stores task information for intelligent retrieval. A RAG Agent, powered by OpenAI's Chat Model and using Window Memory, analyzes and processes the task, drawing context from Weaviate. Finally, the processed task status is appended to a Google Sheet using the Append Sheet node, and any errors are reported via Slack Alert. This workflow is ideal for anyone needing to convert spoken ideas or tasks into structured, actionable data without manual intervention.
Key Features
- Webhook Trigger: Easily receive task data from external voice input services.
- AI-Powered Text Processing: Utilizes Text Splitter and OpenAI Embeddings for intelligent data preparation.
- Vector Database Storage: Leverages Weaviate for efficient storage and retrieval of task embeddings.
- RAG Agent for Reasoning: Employs a Retrieval Augmented Generation agent for context-aware task processing and categorization.
- Google Sheets Integration: Automatically logs task outcomes and status updates to a Google Sheet.
- Slack Alerts: Notifies designated channels in case of any workflow errors.
How To Use
- Set up Webhook Trigger: Configure the
Webhook Triggernode with your desired path (e.g.,voice-task-to-notion). - Configure AI Nodes: Set up
Text Splitter,Embeddings, andChat Modelnodes with appropriate parameters and OpenAI credentials. - Weaviate Integration: Configure
Weaviate InsertandWeaviate Querynodes with your Weaviate instance details and an appropriate index name (e.g.,voice_task_to_notion). - RAG Agent Setup: Connect the
Vector Tool(pointing to Weaviate Query) andWindow Memorynodes to theRAG Agent. Configure the agent's system message and prompt. - Google Sheets Logging: Set up the
Append Sheetnode with your Google Sheet ID and the desired sheet name (e.g.,Log). Map the output from theRAG Agentto the 'Status' column. - Error Handling: Configure the
Slack Alertnode with your Slack credentials and a channel to receive error notifications.
