Overview
How might we design smart comparison so people can trust and act on AI output?
When this pattern fits
- Perfect for complex product categories, B2B software platforms, and marketplaces where users need to compare multiple options across many attributes.
When to skip or lighten it
- Commodity items differing only by price.
- More than five products at once on mobile.
- Spec data too incomplete for fair comparison.

Pattern Definition:Frequently asked questions
What should a comparison table highlight?
Rows where values differ; collapse identical rows. Call out winner per row when objective.
How many products at once?
Three to four on desktop; two on mobile with swipe between pairs.
AI role in comparison?
Extract and normalize specs from unstructured listings; keep human-verified core attributes.
Comparison vs review summary?
Comparison is multi-SKU spec diff. Review summary is sentiment compression for one SKU.
