Automatically Rename Gmail Attachments with AI and Save to Google Drive

Who is this for?

This workflow is perfect for anyone who regularly receives important email attachments like reports, invoices, or PDFs and wants them:

• Renamed using clean AI generated filenames
• Automatically saved to a specific Google Drive folder
• Neatly organized without manual work

It is ideal for freelancers, business owners, accountants, and productivity enthusiasts.

What does it solve?

Manually naming and organizing email attachments takes time and often leads to messy files.

This workflow solves that by:

• Automatically downloading unread Gmail attachments
• Using AI to understand the content and generate clean, consistent filenames
• Saving the renamed files to your chosen Google Drive folder
• Marking emails as read after processing

No more confusing filenames like "Attachment 1.pdf".

How it works

1. The workflow runs on a scheduled interval (every hour by default)
2. It checks Gmail for any unread emails with attachments.
3. For each email:
   • Downloads attachments
   • Extracts and reads PDF content
   • Uses AI to generate a new filename in the format: YYYYMMDD-keyword-summary.pdf
4. Saves the file to Google Drive with the new name
5. Marks the email as read to avoid duplicates

How to set up?

1. Connect these accounts in your n8n credentials:

   • Gmail (OAuth2)
   • Google Drive (OAuth2)
   • OpenAI (API key)

2. Update the folder URL in the Google Drive node to your target folder

3. Optional: adjust the trigger interval if you want it to run more or less often

How to customize this workflow to your needs

• Change the AI prompt to create different naming rules, such as including sender or topic
• Dynamically set Drive folders based on email sender or subject
