Email a Summary of a Drive PDF

Summarize a PDF stored in Google Drive and email the result.

Setup

Connect Google Drive in Download the PDF and set the same PDF file ID there and in Read the PDF bytes. Enable Drive file transit and set its HTTPS hostname in the Read the PDF bytes HTTP allowlist. Connect Encodian in Extract PDF text. Select an available model in Summarize the document. Connect Gmail in Email the summary and set the recipient.

In n8n, set the PDF file ID in Download uploaded File from Google Drive, connect Google Drive and Mistral Cloud, and set the recipient and Gmail connection in Send Summarized text to Gmail. Run either format manually.

Behavior

The workflow downloads one PDF, extracts its text layer, summarizes that text and emails the result with the processing time in Africa/Lagos. Open Flow accepts PDFs up to 700,000 bytes and requires an accessible text layer; scanned images without text are not transcribed. Text extraction and model results can differ between formats and should be reviewed. Large documents may exceed model or execution limits.

The document is sent to Encodian and its text to the selected model. Restrict access to execution data and temporary transit URLs. Read, extraction or model failures stop before email. A failed or uncertain send may have succeeded; check Sent mail before retrying.

Changes to the source

Replace private file and recipient settings. Open Flow uses Encodian text-layer extraction and a configurable AI Agent; n8n keeps the original Mistral summarization chain.
Both formats send plain text. Open Flow checks the PDF, extracted text and model result before email.
