Mesh: Scaffolding Comparison Tables for Online Decision Making
summary
Mesh is a Chrome extension that scaffolds comparison tables by importing open Amazon tabs and additional URLs, fetching reviews that mention each criterion and populating cells with default star ratings that users can override and annotate. Three studies (survey n=89, interviews n=30, lab + field) show concrete gains: users find more correct objective answers faster with lower workload, generate more insightful summaries in 20 minutes, and in a two‑week deployment (5 users) four make real purchases using the tool.
