Check an AI summary against the document that matters
Verify names, numbers and omissions instead of grading a summary by its fluency.
Keep the original within reach
A fluent summary can make a long report easier to approach, but it can also conceal a missing qualification. Use the summary as a navigation aid while keeping the original document available. NIST's generative AI risk profile discusses risks including fabricated content and information-integrity concerns. A practical reader can respond by checking the parts that would change a decision. Start with a defined question, such as what conditions apply to a warranty or which dates govern a project. A vague request for the main points gives you less control over what the system chooses to omit.
Separate extraction from interpretation
Ask for the relevant passages or section locations before asking what they mean. If the tool provides page numbers, check them against the actual document because numbering may differ between the file and the printed pages. Copy the exact passage into your notes when it matters, staying within permitted quotation limits if you publish those notes. Then write your own short interpretation. This two-step process helps you notice when the assistant moves from describing the source to adding an inference. It also makes later verification easier for another person who needs to review your conclusion.
Check the high-risk details
Read every name, amount, date, unit, and condition in the summary against the original. Pay particular attention to exceptions introduced by words such as unless, only, may, or subject to. A table can contain footnotes that change the meaning of an apparently simple number. If the assistant converts units or calculates a comparison, reproduce the arithmetic independently. Do not accept a citation merely because it looks formal; follow it and verify that the cited source supports the attached claim. Keep a list of unresolved details rather than filling gaps with a plausible guess.
Look for what vanished
Compare the summary with the document's headings and conclusion. Did it leave out limitations, dissenting views, exclusions, or the population to which findings apply? A study about one environment may not support a recommendation for another. Ask what evidence would contradict the summary's conclusion, then search the document for it yourself. This is especially useful when the summary sounds more decisive than the original author. Shortness requires omission, so omission alone is not a defect. The defect appears when what disappears is necessary to understand the scope or uncertainty of the claim.
Make the final note accountable
Save the source title, publication date, document version, and the locations of checked passages. Label your note as a verified summary, a provisional reading, or a list of questions as appropriate. If the document has financial, legal, or medical consequences, use qualified professional interpretation for the actual decision. For ordinary work, circulate the original alongside your checked note so others can inspect the basis. The useful skill is not finding a prompt that makes every summary perfect. It is creating a lightweight review process that keeps convenience connected to the evidence that the document actually contains.
