Where each one falls short

Cartesia

  • Instant and professional voice cloning are gated behind paid Pro and Startup tiers, unavailable on the free plan.
  • Voice agent calls carry a separate per-minute usage fee ($0.06/minute) on top of subscription credits.
  • Enterprise features like SSO and BAAs require a custom sales conversation rather than self-serve upgrade.
  • Free tier concurrency limits (2 TTS, 8 STT concurrent requests) may be restrictive for testing production-like load.

Microsoft Teams

  • Resource-heavy application; slow to load and consumes significant CPU/memory compared to alternatives
  • Limited channel structure; maximum of 200 public and 30 private channels per team
  • Cannot invite guest users to specific channels; guest access grants full team visibility
  • Unable to chat during screen sharing; limits real-time collaborative communication
  • Limited customization options for branding and interface; cluttered UX compared to Slack
  • Channels cannot be moved between teams; requires manual replication for reorganization
