Auto-Rename Gmail Attachments with GPT-4o & Save to Google Drive

This workflow automates the tedious task of managing email attachments by checking Gmail hourly for unread emails with attachments. It downloads PDFs, extracts their content, and leverages GPT-4o to analyze and generate descriptive filenames in the format YYYYMMDD-keyword-summary.pdf, ensuring files are intuitively named based on their actual content rather than generic labels like 'Attachment 1.pdf'.

Perfect for freelancers, accountants, business owners, and anyone dealing with frequent invoices, reports, or documents via email. It eliminates manual renaming and sorting, saving hours of productivity while keeping your Google Drive folders neat and searchable.

Setup is straightforward: connect Gmail, Google Drive, and OpenAI credentials in n8n. Customize the target Drive folder, AI prompt, or schedule interval. Benefits include reduced errors, consistent organization, and seamless integration—no more cluttered drives or lost files.

After renaming and uploading, it marks the email as read to avoid reprocessing, ensuring efficient, one-time handling. Ideal for high-volume email users seeking AI-powered file management without manual intervention.
