For a research brief, evaluate ChatGPT on the traceability of its claims, not the fluency of its answer. Its search feature can return linked sources; the useful output is a short list of decisions supported by pages you can open and inspect.
Good fit
A first pass at a question with a defined audience and scope: for example, collecting the requirements for a small team’s next software purchase. Start with a question you can independently verify before trying a broad market report.
Poor fit
A final authority for facts that you cannot check. A polished paragraph or a citation alone does not establish that the source supports the claim. If you need a reproducible dataset, keep the original records outside the chat.
Steps
- Choose one narrow research question and write three acceptance criteria before opening the chat. Specify the region and date if they affect the answer.
- Use web search and ask for a claim-by-claim evidence table. Keep vendor statements separate from your own decision criteria.
- Open each cited page. Record whether it supports the exact claim, whether its date is relevant, and which questions remain unanswered.
- Turn only the supported findings into a brief. Keep a separate list of unknowns and the links you will revisit before acting.
Research [question] for [audience] as of [date]. Return five claims with a primary source link and the relevant date for each. Separate source facts from your inference. If a source does not answer a question, mark it unknown. Finish with the three checks I should perform myself.
Success criteria
A useful trial produces a brief whose important claims can each be traced to a supporting passage. Count unsupported claims and the minutes needed to verify them. Compare those costs with researching the same question directly; do not score answer length as productivity.
Limitations
Search and other features have plan limits. Confirm the current limits in your account before making a recurring workflow depend on them. This guide does not promise a particular free allowance or subscription price.
