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.

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
