Send Specific PDF Attachments from Gmail to Google Drive with OpenAI

This n8n workflow triggers on new emails received in Gmail, iterates through attachments, extracts text from PDF files, and uses OpenAI to determine if they match a configurable search term (e.g., 'invoice', 'receipt', or 'contract'). Matching PDFs are automatically uploaded to a designated Google Drive folder, streamlining document organization.

The workflow begins with the Gmail 'On email received' trigger, followed by looping over attachments to identify PDFs. Each PDF's content is read and sent to OpenAI for semantic analysis against your criteria. Only relevant files proceed to the Google Drive upload node, ensuring only pertinent documents are stored without manual review.

Benefits include significant time savings in processing incoming emails with attachments, reducing errors in document categorization, and enabling scalable automation for high-volume inboxes. Ideal use cases: HR for timesheets or contracts, operations for vendor invoices, finance for receipts, or any scenario requiring intelligent PDF triage from email.

Prerequisites: OpenAI API credentials and Google Drive OAuth2 credentials. Note the disclaimer on varying AI accuracy—validate results initially. Easily customizable search terms via the Configure node.
