Pros & Cons
Perplexity AI
- Comet browser is now genuinely free worldwide since October 2025, removing a previous paywall entirely
- Education Pro’s $10/month rate provides meaningful savings for verified students
- Comprehensive tier structure (Free through Max, Enterprise Pro/Max) serves a wide range of usage needs
- Pro Search’s agentic reasoning mode carries separate request fees ($14-22 per 1,000 queries) beyond standard usage
- Max tier at $200/month represents a substantial cost for individual power users
- Enterprise Max at $325/seat/month is a significant investment for team-wide deployment
Microsoft Copilot
- Pre-bundled SKUs (Business Standard+Copilot, Business Premium+Copilot) simplify combined licensing
- SMB Business tier price cut to $21/user/month in late 2025, with a further temporary $18 promo
- Deep integration across the full Microsoft 365 app suite provides genuine workflow-embedded AI assistance
- True all-in cost ($69-90/seat/month) is substantially higher than the standalone Copilot add-on price alone
- Requires a qualifying Microsoft 365 license as a prerequisite — not purchasable independently
- Base Microsoft 365 suite prices also increased July 1, 2026, compounding the total cost increase
