Build Your First AI Agent in Minutes
We built a daily AI agent that saves 20+ minutes each morning—here’s how you can too
Business mornings shouldn’t start with a scramble for information. Weather checks, calendar reviews, and manual cross-referencing eat up your time before you even get to work. For entrepreneurs, every minute counts, and small inefficiencies add up fast.
Imagine waking up to a personalized message that already weighs your schedule, the weather, and even air quality, delivering actionable recommendations for the day. That’s what’s possible when you build your own AI agent in n8n. Here’s how we built an assistant to automate exactly this kind of workflow.
Building a Weather-Aware Daily Assistant in n8n
To show what’s possible, we emulated a busy solopreneur who wants a smarter start to the day. The goal: create an n8n agent that reviews your calendar, checks the weather and air quality, and emails you a tailored trail running recommendation, before you’ve finished your first cup of coffee.
We started with a blank workflow, connected all the necessary APIs, and crafted a focused prompt. In minutes, our AI agent was sending personalized, actionable suggestions, saving us at least 20 minutes every morning.
Why n8n Makes Agent Building Practical
Automates start-to-finish: Scheduled triggers mean your agent runs daily, no manual setup needed
Brings your data together: Integrates with Google Calendar, Gmail, Sheets, weather services, and any custom API
Adapts to your workflow: Node-based design makes it easy to add, remove, or rewire tools as your needs change
Remembers context: Built-in memory keeps the agent’s responses coherent and relevant
No code required: Drag-and-drop nodes keep things accessible—even for non-technical business owners.
How We Did It
Here’s a step-by-step playbook for building our agent in n8n—ready for you to adapt to your own business routines.
1. Start a New Project & Workflow
We kicked things off by creating a new n8n project—keeping workflows and credentials organized and isolated. Starting from scratch meant no tangled legacy settings.
2. Add a Scheduled Trigger
The Schedule node became our automated starting point. We set it for 5:00 AM, so the agent would prep our day before we even woke up.
3. Insert the AI Agent Node
From the AI section, we added the AI Agent node. This is the “brain” of the operation—connecting data, memory, tools, and logic in one place.

A Little Sneak Peek Into Agents
We’re cooking up a brand-new course on building AI agents without coding—but since you’re here, you’re getting the first taste before it’s ready. This week’s how-to includes an excerpt straight from the course, designed to give you a quick, practical win and a peek at what’s coming.
In the full release, you’ll learn how to:
Understand how AI agents think, adapt, and use memory
Connect agents with real tools like Google Calendar, Gmail, and APIs
See how agents go beyond simple automations
Build and test your own working agents step by step
This sneak peek is just the beginning—you’re seeing it before we share it with anyone else.
4. Configure the Agent’s Brain (LLM)
We connected our OpenAI API key and selected GPT-4o-mini for a balance of speed and cost. This gave the agent powerful reasoning abilities for daily recommendations.
5. Set Up Agent Memory
Simple memory was enabled with a context window of 5. This lets the agent remember recent exchanges—so it can build on past information and stay relevant.
6. Integrate Essential Tools
We connected Google Calendar (to check events), Open Weather Map (for weather), Google Sheets (for personal trail data), and Gmail (to deliver the summary). Each connection required proper credentials and permissions, but setup was straightforward in n8n.
7. Add Custom Tools Using HTTP Requests
To include air quality, we registered for an airnow.gov API key and created an HTTP Request node. The node was configured with our endpoint and set to parse JSON for easy downstream use.
8. Craft a Precise Agent Prompt
We wrote a prompt that defined the agent’s identity, tasks, available data, and output format:
‘You are a trail running assistant. Each morning, check my calendar, the weather, and air quality. Suggest the best time and route for a run and email me a summary.’
The prompt was set directly in the AI Agent node.
9. Save & Organize
We renamed each node descriptively (“Get Weather,” “Fetch Calendar,” etc.) and saved progress frequently to avoid any data loss.
10. Test & Debug
We ran test executions. If errors popped up (like a missing API parameter), we used the workflow logs and n8n’s AI assistant to troubleshoot and correct any issues.
Optional: Enable Chat Interface
For direct questions, we added a chat trigger node—letting us message the agent in real time from within n8n or even through Slack.
This setup now runs daily—delivering actionable, context-aware insights to our inbox and freeing up valuable time.
Other Ways to Use This
The same n8n agent structure can automate countless routines for entrepreneurs and business teams. Here are a few ideas to spark your own applications:
Sales: Send a daily lead summary and suggested follow-ups based on CRM and email data
Marketing: Create a morning digest with live campaign stats, weather for events, and trending content
Project Management: Summarize key tasks and deadlines from Jira, Trello, and Google Calendar
HR: Automate onboarding checklists and reminders using Sheets, Calendar, and email
Consulting: Prep personalized client updates by pulling from multiple data sources

💡Bonus Pro Tips
Use Clear Node Names: Rename every node for clarity. It makes troubleshooting and future edits much easier
Iterate Your Prompt: Small prompt tweaks can improve output dramatically. Test and refine for best results
Credential Management: Regularly audit API keys and OAuth permissions to prevent outages
Export & Backup: Save your workflow after major changes—restoring from a backup is faster than rebuilding.
⏭️ What’s Next
That’s a wrap for today’s send—hopefully the weather-ready agent gave you a spark for building smarter workflows of your own.
As always, we’ll be back Thursday with the latest AI news, updates, and breakthroughs you don’t want to miss.
See you then 👋
