This n8n template builds upon a simple appointment request form design which uses AI to qualify if the incoming enquiry is suitable and/or time-worthy of an appointment. This demonstrates a lighter approach to using AI in your templates but handles a technically difficult problem - contextual understanding! This example can be used in a variety of contexts where figuring out what is and isn't relevant can save a lot of time for your organisation. How it works We start with a form trigger which asks for the purpose of the appointment. Instantly, we can qualify this by using a text classifier node which uses AI's contextual understanding to ensure the appointment is worthwhile. If not, an alternative is suggested instead. Multi-page forms are then used to set the terms of the appointment and ask the user for a desired date and time. An acknowledgement is sent to the user while an approval by email process is triggered in the background. In a subworkflow, we use Gmail with the wait for approval operation to send an approval form to the admin user who can either confirm or decline the appointment request. When approved, a Google Calendar event is created. When declined, the user is notified via email that the appointment request was declined. How to use Modify the enquiry classifier to determine which contexts are relevant to you. Configure the wait for approval node to send to an email address which is accessible to all appropriate team members. Requirements OpenAI for LLM Gmail for Email Google Calendar for Appointments Customising this workflow Not using Google Mail or Calendar? Feel free to swap this with other services. The wait for approval step is optional. Remove if you wish to handle appointment request resolution in another way.

Description This workflow automates email categorization in Gmail using the Gmail API and OpenAI's language model. It periodically checks for new emails, reads their content, and categorizes them based on existing Gmail labels. If no matching label is found, the workflow creates a new label and assigns it to the email. Key Features Polling for Emails**: The workflow triggers every 5 minutes to check for new emails using the Gmail Trigger node. Reading Labels**: Existing Gmail labels are fetched to determine the most relevant match for email categorization. Dynamic Labeling**: If no existing label matches, a new label is created dynamically based on the email's content. OpenAI Integration**: The workflow uses OpenAI's Chat model to analyze email content and suggest or create appropriate labels. Email Categorization**: Labels are applied to emails, ensuring they are organized in Gmail's structure. The workflow also removes less relevant emails (e.g., ads) from the inbox. Nodes in Use Gmail Trigger: Polls Gmail every 5 minutes for new emails. Gmail - Read Labels: Fetches all existing Gmail labels. Gmail - Get Message: Retrieves the full content of a specific email. Gmail - Add Label to Message: Assigns a chosen label to the email. Gmail - Create Label: Creates a new label if necessary. OpenAI Chat Model: Analyzes email content for categorization. Memory Buffer: Retains context for email analysis across multiple iterations. Wait Node: Adds a buffer period to manage email processing. Prerequisites Gmail API Setup**: Ensure Gmail OAuth2 credentials are configured in n8n. OpenAI API Key**: Configure OpenAI credentials for email analysis. Labeling Standards**: Maintain a consistent Gmail label structure for better organization. Instructions Add your Gmail API credentials to the Gmail nodes.

Who is it for? If you are getting a lot of emails into your Gmail inbox, then probably some of those can be solved easly by replying or by doing specific short tasks. But analyzing whole email thread content just to catch up with multiple threads can be very wasteful. So by using AI you can actually get simple propositions of what should be done before closing this specific email and actual proposed answer to that email. This is especially useful if you need to do some actions before replying to email. In that case you can simply assign task to specific person, await until it's done, copy-paste AI answer when it's done, and close. Another good use would be if on one inbox there are working multiple people. It can make the process much more streamlined. How It Works? Script runs on your selected trigger. If you are using section "Read and Star", then you may use "Email Trigger". Automation is looking for exiting open Todoist tasks, that have the same title as email If task does not exist, then we are asking AI to analyze thread and give output that is Todoist-API-ready: having summary of email content having proposed actions to be taken having proposed answer to this email If email was unstarred for some reason but task was not closed, then task is being closed automatically. Script FOR PURPOSE is not trying to unstar messagess which have closed tasks, because this could lead to some inconsistencies. How to set up? Select and setup your triggers, depending on your needs Setup connections using N8N instructions. You will need: Gmail Todoist AI (in this workflow OpenAI is used) (Optional) Remove "Read and Star" section if you don't want tasks automatically read and starred. (Optional) Adjust AI node - especially useful if you want to use different model or have response in different language NOTE Chat does not heave memory attached on purpose. The purpose is that it should analyze each inbox message separately, not in thread. When using memory, it can get lost easily. NOTE2 You might want to adjust limits on nodes "Get Unread From Inbox", "Get Starred From Inbox" and "Get Open Tasks", especially if having issues with model complying to output structure. And that's it. I hope that this automation will make your Gmail <-> Todoist process much more streamlined! What's More? There is actually more that you could do with this automation, but it really depends on your needs. For example, you could add Form trigger to handle incoming support requests. Another thing is that you could replace Todoist with Asana or any database (like NocoDB) if you are using it for your task management.

Workflow Description This workflow helps content creators automatically repurpose YouTube videos into SEO-friendly blog posts. It extracts the video transcript, uses AI to generate a full blog post with a relevant image, and sends the complete package via email, ready for publication. Prerequisites/Requirements This workflow relies on external AI services. You will need: OpenAI Account: Used for generating the blog post text (specifically mentioned using GPT-4o in the workflow notes). Credentials: Requires an API key from OpenAI. Cost: OpenAI API usage is typically paid based on the amount of text processed (tokens). Check OpenAI's current pricing. Setup: Sign up at OpenAI and obtain your API key. Dumpling AI Account: Used for retrieving YouTube video transcript and generating the blog post image. Credentials: Requires an API key from Dumpling AI. Cost: Dumpling AI offers 250 free credits to start with and different plans for different levels of usage. Check the pricing page for more details. Setup: Sign up at Dumpling AI and obtain your API key/credentials. Email Account: Credentials for the email service (e.g., Gmail) used to send the final result. How it works Input Video Details: You provide the YouTube video URL and your email address. Get Transcript: The workflow fetches the transcript of the specified YouTube video. Generate Content: An AI model crafts a blog post (title, description, body) based on the transcript. Create Image: Another AI model generates a suitable image for the blog post. Format & Package: The blog post is converted to HTML, and the image is prepared for sending. Email Result: The final HTML blog post and image are emailed to you. Set up steps Configure Variables: Enter the specific YouTube video URL and the recipient email address in the "Set Variables" node. Connect Credentials: Add your credentials for the services used (e.g., OpenAI for text generation, Dumpling AI for YouTube Transcript and AI image generation service). Connect Email Credentials: Authenticate your Gmail account (or chosen email provider) to allow the workflow to send the email. Take it to the next level Direct Publishing:** Instead of emailing the result, connect directly to your CMS (like WordPress, Ghost, Webflow) to automatically create a draft or publish the blog post. AI Agent Integration:** Replace the single "Generate Blog Post" step with an AI Agent for more sophisticated content generation, potentially researching topics or structuring the post section by section based on the transcript. Social Media Snippets:** Add steps to generate companion social media posts (e.g., for Twitter, LinkedIn) summarizing the blog post. Batch Processing:** Modify the trigger to read multiple YouTube URLs from a spreadsheet or database to convert videos in bulk. Enhanced SEO:** Refine the AI prompts to specifically target keywords or incorporate SEO best practices more deeply into the generated content. Multiple Image Options:** Generate several image variations and include them in the email or draft post for selection.

This n8n template reviews and audits recently active Google Drive files and reports on files with excessively open permissions. This shows how you can automate simple compliance tasks for access control management. File Sharing Permissions are routinely abused when access needs and scopes expand to many colleagues, clients and users. Often, granting excessively open permissions means you can get back to work rather than deal with numerous access request notifications. Whilst sometimes justified, the problem is that the permissions are rarely reverted to a safer setting at a later date when it is no longer needed. This template serves to improve your security posture by giving frequent reminders of these open files so that they can be actioned and not forgotten about. See example Audit Report here: https://docs.google.com/spreadsheets/d/1V2aiLhp3_nH7EBniMn7D0kFHg7-A5NjpDZXMhb4F5UI/edit?gid=503992967 How it works A scheduled trigger runs everyday to generate a new audit report. A new sheet is created in a designated Google Sheets document to store the day's results. The Google Drive node is used with Advanced Search params to fetch recently modified files for the user with each file result containing the current permission settings. The results are filtered for those with publicly accessible "anyone with link" and sharing with external users via domain. The results are then manipulated into rows so that we can append them to the Sheet we created earlier. The audit Google Sheet is updated with the results and an audit report is sent to the user to action. How to use Set the scheduled trigger to a more appropriate interval which works for you or your organisation. Consider using allowlists for organisations you frequently share with to reduce the number of false positives. The results can be forwarded to other security or analytical products as required. Requirements Google Drive for Document Management Google Sheet for Reports and Data Collection Gmail to Email Reports Customising the workflow Not using Google? Apply the same approach using Microsoft Sharepoint or Dropbox. If your security policies require it, you could automate fixing the file permissions as a proactive action instead and notify the user later.
