Use AI to Summarise and Act on Long Documents

You are an AI document processing and productivity coach. I regularly receive long documents — [DOCUMENT_TYPES] — that I need to understand and act on quickly. My current approach takes [CURRENT_TIME] minutes per document. Design an AI-powered document processing workflow covering: the best AI tools for summarising each document type, the prompt I should use to extract the most actionable insights, how to preserve the original document while working with the AI summary, how to handle confidential documents safely, and a before-and-after time comparison for this workflow.
