ChatGPT: ask questions of a document with evidence

Use a short document you may share and record its title and version. Choose a question whose answer is known so you can test retrieval first.

Compiled for Sorlavit Kim · Published · Updated · 2 min read

Environment and inputs: ChatGPT user guide · Feature and source access depend on the active account, app and organization settings. Optional file or app steps have a text-excerpt fallback. No fixed model version, price or usage quota is assumed.

What you will make

A practical ChatGPT guide to ask questions of a document with evidence. Use the sample input and prompt, then check the result. Use a fictional small-office IT team as the practice setting. Keep the approved facts in a clearly labeled source block.

Prepare the source and scope

Use a short document you may share and record its title and version. Choose a question whose answer is known so you can test retrieval first. Open the ChatGPT app or website and start a focused conversation for this exercise.

Try this prompt

In ChatGPT, provide the prepared input, then send the following request. For real work, replace fictional details with approved facts.

Using only this document, answer who approves equipment purchases. Give the section and a short supporting excerpt. If the document does not say, answer Not specified.

Review the result

Locate the excerpt in the actual source and distinguish the approver from the person submitting a request. Record each correction and its supporting source.

If the answer is wrong or incomplete

A document title alone does not grant access to its contents. Provide the text if the source cannot be read. For recurring work, keep the active source list with the project brief; for a one-off task, supply just the relevant excerpt.

Practice and completion check

Repeat with one incomplete input. Check the answer against the review criteria, remove unsupported claims and save the prompt with its source version. This workflow has not been verified in a customer deployment.
