# Split and review multi-document PDFs with pdfRest, GPT-4.1-mini, and Google Drive

> Quick overview Upload a PDF containing multiple documents, use AI to suggest document groups, and review titles, categories, and page ranges in a guided form. pdfRest creates separate PDFs and a downloadable ZIP with a page manifest, with optional Google Drive filing. How it works 1. Receives a PDF through an n8n upload form and verifies that exactly one valid PDF was provided. 2. Uses pdfRest to inspect the PDF, run OCR to create a searchable master copy, and split the master into individual page PDFs. 3. Uses pdfRest to convert each page to Markdown, then compiles a full-page inventory while preserving original page numbers and flagging low-text pages. 4. Sends the combined extracted text to OpenAI (via the n8n LangChain Information Extractor) to propose contiguous document boundaries with document type, title, counterparty, and evidence-based reasoning. 5. Presents editable titles, categories, and start/end page numbers for each proposed document. Reviewers can exclude groups or add
