I’ve built a pretty simple AI Agent in n8n using GPT-4 as the LLM, with basic memory and Notion Tools integrated.
The setup is:
Trigger: A message in a chat
Agent: Connects to GPT-4 ( brain )
*** Basic memory
Tools:
Notion Search Tool (to access all databases)
Notion Write/Create Tool
Issue 1: The “Tomorrow” Bug
When I send a message like “Set up a meeting for tomorrow”, the AI creates an entry in Notion, but the date ends up being randomly set in October 2023 instead of the actual “tomorrow” from today. It’s super inconsistent and I can’t figure out why.
Anyone know why this is happening or how to make the agent or GPT correctly interpret relative dates?
Issue 2: Can’t Update Existing Entries
I want the agent to update entries in Notion, not just create new ones. When I add another Notion Tool to handle updates, the agent seems to ignore it and just creates a new entry instead. I’ve tried different configurations, but can’t get it to modify an existing one.
How do you configure the Notion update function correctly so that the AI knows which entry to update and doesn’t default to creating a new one?
Bonus Question: Leveling Up with n8n
Are there any good tutorials, guides, or workflows you recommend to take my n8n experience to the next level? Especially for working with AI Agents and integrations like Notion, Airtable, Emails ( not only gmail ) etc
If you’ve solved anything similar, I’d love your input. Even better if you’ve got a working example of an AI Agent using Notion for both creating and updating entries properly.
// Check if the input is intended to view meetings rather than create one.
// If the input contains keywords like “what”, “show”, or “list” followed by “meeting”
const viewMeetingPattern = /(what|show|list).*meeting/i;
if (viewMeetingPattern.test(input)) {
// For a view query, simply forward the original input to be handled downstream.
return [
{
json: {
chatInput: input, // Pass along the original query.
sessionId: sessionId,
intent: ‘view’
}
}
];
}
// Otherwise, assume the input is a command to create a meeting.
// Initialize days offset (relative to today)
let daysOffset = 0;
if (/in\s+(\d+)\s+days/i.test(input)) {
daysOffset = parseInt(input.match(/in\s+(\d+)\s+days/i)[1]);
} else if (/tomorrow/i.test(input)) {
daysOffset = 1;
}
// Calculate the meeting date.
const today = new Date();
let meetingDate = new Date(today);
if (daysOffset > 0) {
meetingDate.setDate(today.getDate() + daysOffset);
}
const dateString = meetingDate.toISOString().split(“T”)[0];
// Extract the meeting time (e.g., “at 19:00”)
const timeMatch = input.match(/at\s+(\d{1,2}:\d{2})/i);
const time = timeMatch ? timeMatch[1] : ‘09:00’;
// Extract the person’s name (assumes the word following “with”)
const personMatch = input.match(/with\s+(\w+)/i);
const person = personMatch ? personMatch[1] : ‘Unknown’;
// Build a structured message for meeting creation
const outputMessage = `Please create a meeting in Notion with the following details:
Person: ${person}
Date: ${dateString}
Time: ${time}
Location: Not specified
Topic: Not specified
Make sure the meeting is saved and confirmed. Do not ask for suggestions.`;
