1. Define what you need to get

Before opening an assistant, clarify your purpose: are you looking for background for a meeting, a list of obligations, an explanation of a report, or outstanding tasks? Consider who will read the result and what decisions it might support. A summary for locating relevant sections does not need the same detail as a synthesis of commitments and people responsible. Defining the task helps avoid a lengthy response that merely rephrases the text without meeting your actual need.

Specify the scope and format that would be useful: for example, points by section, dates, responsible parties, and open questions. Ask it to distinguish what the document states from inferences and information it cannot find. If there are exceptions, conditions, or negatives, say they must be retained. The goal is not for the summary to sound conclusive, but to help you return to the original and check what matters.

If you do not yet know what to prioritize, start with an overview and then ask narrower questions. You can also request different levels of detail for different parts: brief background and greater precision on dates or requirements. The length should suit the intended use; it should not replace reading the decisive passages.

2. Check whether you may share the file

Before uploading anything, check whether the document contains personal data, customer information, financial or health information, credentials, contracts, or internal plans. The fact that a service accepts files does not mean you are authorized to send them. Your employer, educational institution, client, or team may have policies restricting the use of external tools. If you do not have permission, use an approved alternative or work without AI; removing names does not guarantee that the content is no longer identifiable.

Review the privacy controls and terms of the specific service you intend to use, and follow your organization’s policies. Do not assume that settings available in one tool also apply to others, or that changing a data option authorizes you to upload confidential information. If you cannot confirm that the use is permitted, do not send the file.

If only part of the file seems sensitive, do not assume that hiding names is enough. The remaining context, figures, or details may still make a person or matter identifiable. If an approved version exists for this use, confirm that it is the version you will use and that it retains the information needed for the task. Privacy settings do not replace authorization to share data.

3. Prepare the document and ask for traceability

Confirm that you have the correct version and consider which elements need to appear in the summary. Tables, appendices, footnotes, comments, or scanned pages deserve specific attention: do not assume they are included or interpreted as expected. For long files, it may be easier to work chapter by chapter or section by section, keeping the headings so you can check them later.

Ask for references you can locate rather than simply requesting a confident answer. A useful instruction would be: “Summarize the main points by section. For every important claim, indicate the heading or a passage I can locate that supports it. Separate what the document states, inferences, and missing information. If you find no support, say so.” You can also ask it to retain conditions and negatives and not turn a possibility into an obligation. A generated reference is a lead to verify, not automatic proof.

If possible, request the page number or exact heading. A distinctive excerpt can also help you find the passage. Then search within the file and confirm that it supports the meaning attributed to it: a phrase appearing somewhere is not enough if it concerns another subject or includes an omitted condition.

4. Check facts that could change a decision

Review conclusions, dates, amounts, responsible parties, commitments, and requirements first. Check the context, not just whether a fact appears: a figure may relate to a different period, and a date may be a proposal rather than an agreed deadline. For every obligation, verify who must act, what they must do, and under what condition. Words such as “unless,” “except,” and “not” can change the scope of a statement if they disappear from the summary.

To organize the check, mark each point as supported, partly supported, inferred, or unsupported. Keep what is substantiated, correct what is incomplete, and discard anything you cannot justify from the original. If the summary includes direct quotations, check that they are verbatim and that fragments have not been joined in a way that changes their meaning. Microsoft documents that Copilot in Word can summarize and reorganize content directly in the document; that capability does not itself verify every claim, so check the references against the file. (Microsoft Support)

For numbers, also check units, periods, and notes that limit their interpretation. In task lists, distinguish a general responsibility from an action assigned to a specific person. Do not judge only whether the summary is coherent or well written: what matters is whether each claim preserves the scope of the source text.

5. Review omissions and the tool’s limits

Once you have checked the claims, compare the summary’s structure with the complete document. Go through headings, closing sections, tables, and appendices to identify definitions or exceptions that might change how another passage should be read. Ask yourself what important information was left out and whether its absence would alter a conclusion. Not every section needs to appear: the check helps you decide whether an omission is acceptable for the purpose you defined.

Microsoft describes Copilot in Word as a feature that can help users understand long or complex documents and quickly find what matters; this describes a product capability but does not guarantee that every summary covers the entire file correctly. Check what the version you have offers and compare the result with the document. (Microsoft Support)

A simple check is to compare the original headings with the topics in the summary. Every section does not need a mention, but it is worth reviewing omitted parts to determine whether they contained limitations or relevant information. If a table, appendix, or scanned page has not been covered reliably, review it separately or prepare a manual summary of that passage.

6. Use the result as a draft, not a replacement

A summary can serve as a quick index, a draft set of notes, or a list of questions to take back to the file. It does not replace the original when interpreting an obligation, supporting a high-impact decision, or delivering text that requires documentary precision. Keep the reference document and the locations of verified passages. If you share the result, follow your organization’s rules on AI use and document handling.

Do not assume the process will save time: generation, reference searches, and corrections all take time. An experimental study with economics students assessed written-analysis tasks in Thai and mathematical and data-analysis tasks using Stata. Its findings relate to those tasks and participants, not document summarization; therefore, they do not show how much time is saved by summarizing a contract, report, or academic paper. (arXiv)

Before using or distributing the summary, apply a short checklist: authorized file, locatable references, checked figures and exceptions, reviewed coverage, and a person responsible for the result. If anything fails, treat it only as initial guidance and return to the original before acting. You can keep outstanding questions and passages needing interpretation alongside the summary; this makes clear what has been checked and what has not. The value lies in finding your way and returning to the source, not replacing it.
