A PDF inbox that summarises itself: Google Drive, n8n and an LLM (free workflow)

说明与用途

当PDF文件被添加到Google Drive文件夹时，自动创建一个Google文档，摘要文件内容、关键事实、页码和所需操作，使用Apify进行转换，LLM进行摘要。

问题

Teams often have PDFs that are never read; the goal is to automatically summarize new PDFs in a Google Drive folder.

结果

The workflow automatically creates a summarized Google Doc for each PDF added to the inbox, including key facts, page numbers, and required actions, with minimal manual intervention.

工作流

• 1. Google Drive Trigger polls the "PDF inbox" folder every minute. 2. Trigger sends file URL and name to a webhook. 3. Webhook forwards data to the Apify "Document to Markdown" actor via HTTP request. 4. Actor converts PDF to Markdown, preserving tables and inserting <!-- Page N --> markers. 5. If conversion succeeds, an LLM chain (gpt‑5‑mini) summarizes the Markdown. 6. Summary, source metadata, and full Markdown are inserted into a new Google Doc. 7. If conversion fails, the file and error are logged and no charge is incurred.

证据

Drop a file into a Google Drive folder, and a minute later there is a Google Doc next to it that says what the document is, lists the key facts with page numbers, and says whether anyone has to do something.

来源

The Actor runs in the cloud and downloads files by URL. It never sees your Google account.

来源

The conversion took 0.9 seconds; the whole run, including container start, about 10 seconds.

$1.50 per 1,000 pages with a text layer, +$5 per 1,000 for pages that need OCR, up to 25 % less on higher Apify plans.
