Perplexity

The canonical sample contains 103 reachable videos that were fully audited from their complete transcript and ordered frames. It shows two systems operating at different times: Perplexity's 2025 Campus Partner and Comet referral pushes paid creators or participants to recruit, install, activate, and re-share, while software educators built a broader shelf of narrow interface tutorials, research-to-deliverable demonstrations, and browser-agent workflows.

The Comet referral program ended on 2025-11-06, so its codes and payout walkthroughs are historical evidence, not a current commission claim. Cost-bounded exclusions are explicit rather than silently treated as findings: 72 videos exceeded the ten-minute audit ceiling, seven were unavailable at authenticated preflight, and sixteen failed artifact capture after the bounded retry; every excluded URL and reason is preserved in the research ledger.
