How to Use AI to Summarize Documents and Contracts

Use AI to summarize long documents and contracts into key points and questions, with guardrails for accuracy and legal review.

To use AI to summarize documents and contracts, paste the text into an assistant and ask for a plain-English summary, the key terms, and any questions you should ask. This helps you grasp long material quickly, but it does not replace professional advice on legal or financial documents.

This guide covers safe, useful summarizing. For data rules, read our governance checklist.

What a good summary request looks like

  • Summarize this in five plain-English points
  • List the key dates, costs, and obligations
  • Flag anything unusual or risky
  • Suggest questions to ask before signing

A simple process

  1. 1

    Paste the text

    Provide the full document or section..

  2. 2

    Ask for structure

    Request points, terms, and questions..

  3. 3

    Verify the detail

    Check key clauses against the original..

  4. 4

    Get advice

    Have a professional review anything binding..

Treat the figures below as third-party research and general context, not a forecast for your own business.

Where AI can go wrong

AI can miss or misstate clauses in long documents. Treat its summary as a guide to read more closely, not as the final word on what a contract says.
