Posted on Mar 28
Workflow
The author built a personal AI assistant using n8n to automate email, calendar, and task management. The workflow uses a Webhook trigger, an OpenAI GPT-4 node for intent classification, and IF nodes to route requests to specialized Gmail, Google Calendar, or Notion workflows. Human involvement is implied through initial setup and ongoing monitoring, though the source does not explicitly detail a continuous human-in-the-loop review process for every automated action.
Reported result
The author reports that the assistant handles approximately 70% of routine email tasks and 80% of overall routine tasks after two months of tuning. They claim to save 15+ hours per week. However, these metrics are self-reported anecdotes without independent verification. The source also notes early failures, such as inappropriate email sends and scheduling errors, which required iterative fixes.
Human role
The original post does not say how a person stayed involved.
Limitations
Prerequisites include installing n8n (self-hosted or desktop) and configuring API keys for OpenAI, Gmail, Google Calendar, and Notion. Operating costs are estimated at $20-30/month for API calls. Key constraints include API rate limits, potential privacy risks as data passes through third-party APIs, and the need for robust error handling to prevent silent failures. The source reliability is secondary, as it is a personal blog post.
Try it
Act as an automation engineer. I want to build a personal assistant workflow in n8n to handle [replaceable: email/calendar/task] requests. 1. **Setup**: Install n8n locally. Connect [replaceable: Gmail/Outlook] and [replaceable: OpenAI] credentials. 2. **Core Logic**: Create a workflow with a Webhook trigger. Add an OpenAI node to classify incoming text into categories: EMAIL, CALENDAR, TASK, or GENERAL. 3. **Routing**: Use IF nodes to route each category to a specific sub-workflow. For EMAIL, draft a response using OpenAI but set the output to 'Draft' only. 4. **Safety**: Implement a 'Human Review' step. Do not auto-send. Instead, send the draft to [replaceable: Slack/Email] for my approval. 5. **Dry Run**: Execute the workflow with 3 sample inputs. Show me the classification result and the drafted response for each. 6. **Confirmation**: Wait for my explicit 'approve' command before enabling any auto-send or calendar booking features. If any API key is missing or a service is unreachable, stop and report the error. Do not proceed with partial automation.
