Compare your sources. Make a clearer decision.

Start with the decision

Name the decision before asking for a summary. “Choose a vendor for a six-week rollout” gives the Agent a more useful frame than “read these PDFs.” Add the audience and the questions the decision maker must resolve.

Create a Project, upload the relevant files, and put persistent requirements in Project instructions. A separate Session for each comparison keeps the conversation focused while the Project retains shared context.

Make the evidence inspectable

Request columns for the criterion, each option’s stated position, the source location, and any unanswered question. If a proposal does not mention support hours, the table should say “not stated.” A plausible answer is not a substitute for a source.

If you add web research, ask for links and a distinction between current vendor documentation and claims from the supplied files. Check the linked page yourself when the decision depends on a changeable fact.

Challenge the recommendation

Open the resulting file in Preview. Check the most consequential rows against the originals. Ask which assumptions would change the recommendation, and whether all options were evaluated using the same criteria.

Save the final brief in the Project and retain the inputs. A future Session can update the comparison when a new proposal arrives. Bookmarks help you return to useful replies; Archive → Wiki is useful for findings that should become lasting knowledge.

Try it with a small example.
