The quick read
- Give both the same research question and time boundary.
- A discovery tool can feed a separate drafting workflow, but moving between products creates its own overhead.
Choose the stage
If the task is discovering sources, examine how quickly each product leads to relevant original material. If the task continues into analysis or drafting, evaluate that continuation too. Current modes and tools matter more than a broad label attached to the product.
Check the source trail
Give both the same research question and time boundary. Open important citations, inspect dates and distinguish original announcements from commentary. Count unsupported conclusions and missed qualifications, not merely the number of links.
Use complementary strengths when useful
A discovery tool can feed a separate drafting workflow, but moving between products creates its own overhead. Compare one-product and two-product processes on the complete result. Choose based on reliable evidence and the work needed to produce a checked brief. This framework does not assume that a search-led answer is automatically factual or that a general assistant cannot research. The source trail has to earn that trust.
