Overview

End-to-end automation that ingests Gmail attachments, classifies them, and files them in Drive for easy sharing with your accountant.

The AI agent connects Gmail to Google Drive, pulls PDFs from emails, uses OpenAI to classify each PDF as an invoice or receipt, stores them in a dedicated Drive folder, and can email the documents to your accountant or team. It creates an auditable history of processed files and provides a simple way to access and share all documents.

FAQ

FAQ

Common questions about the AI agent and its operation.

The AI agent primarily processes PDFs, classifying them as invoices or receipts. It can be extended to handle other document types if needed, but this often requires additional parsing logic. Attachments that aren’t PDFs can be ignored or logged for review. The agent maintains an audit trail of all actions for accountability.

Yes. You can specify senders, domains, or date ranges to limit which Gmail messages are processed. Filters help avoid processing unrelated messages. You can adjust these at setup or via configuration. The agent logs which emails were included or excluded.

Files are stored in a dedicated Google Drive folder created by the AI agent. Naming follows a consistent pattern that includes date, type (invoice/receipt), and vendor. This ensures predictable sorting and easy search. You can customize the naming convention if needed.

Yes. The OpenAI model can be fine-tuned for your taxonomy and you can adjust rules for routing, such as sending receipts to a specific subfolder or forwarding invoices to a chosen recipient. If you require more complex routing, you can add supplementary steps in the workflow. Regular audits ensure classification accuracy over time.

Yes. Every processed document leaves an audit record with timestamps, source email, classification result, and final destination in Drive. The log supports compliance and easy reconciliation. You can export summaries for accounting reviews. This ensures traceability for internal or external audits.

Yes. The AI agent can be configured to operate across multiple Gmail accounts and Drive folders with distinct folders per project or client. Access controls ensure data isolation between accounts. Each configuration maintains its own audit trail and notification settings. You can centralize administration while preserving separation of concerns.

If a misclassification is detected, you can review the classified file in Drive and reclassify it. The system can be set to flag uncertain items for human review before final storage or distribution. Over time, re-training with corrected labels improves accuracy. Anomaly reports help identify recurring misclassification patterns.
