Pros & Cons

Perusall

  • Genuinely free when using uploaded materials or open educational resources
  • Institutional Basic/Premium licenses eliminate per-student fees entirely for adopted materials
  • Courses set up before July 6, 2026 remain unaffected by the new pricing model
  • New courses at unlicensed institutions after July 6, 2026 can no longer offer a $0 Student Access Fee option
  • Instructors must now choose a $5-25 per-student platform fee for new courses without an institutional license
  • A real shift away from the previously free model specifically for unlicensed institution new-course setups

Bing Copilot Search

  • Built directly into widely used Microsoft products, requiring no separate signup
  • Provides source citations for verifying synthesized answers
  • One of the most widely distributed AI search experiences by sheer reach
  • Dedicated answer engines have iterated faster on citation quality and search-specific behavior
  • Built-in distribution doesn’t necessarily mean best-in-class search capability
  • Worth comparing directly against specialized AI search tools if search quality is the priority
