SaaS landing page
Compare with baselineBrief · sent to the model word for wordTempo is a shared calendar tool for small teams of 5 to 50 people. Its main selling point is "automatically finds a time when everyone is free."

Show three metric cards: today's revenue, number of orders, and average order value; a line chart of revenue over the last 30 days; a bar chart comparing sales across locations; a table of the top 5 best-selling items; and a date range picker. Use hard-coded sample data.

SkillArena itself
Compare with baselineBrief · sent to the model word for wordSkillArena is a website that compares UI skills for AI coding agents. Build its home page: a header with the logo and navigation (Matrix, Compare, About, Waitlist); a hero that explains that every page on the site was generated from the same product brief with a different skill; a matrix where rows are skills (the first row is a "no skill" control group) and columns are four briefs, each cell showing a screenshot thumbnail (use placeholder boxes); and a waitlist form with email and a role choice. Use placeholder skill names.
