Corti

  • +API-first: drops ambient documentation, coding, and guidance into existing EHRs
  • +Real-time guidance during encounters, not just after-the-fact notes
  • +Pay-as-you-go developer pricing plus enterprise plans
  • -Decision support and documentation, not an autonomous clinician; clinician review required
  • -Developer-oriented; less of a finished end-user product than some scribes

Sindarin

  • +Focused on the genuinely hard problems: low latency, turn-taking, and interruption handling
  • +Broad multi-channel deployment from one Persona, including an unusual Unity SDK for game characters
  • +Dual no-code and developer paths with a free tier to start
  • -Very small, reportedly bootstrapped team, raising durability risk versus larger voice platforms
  • -Thin public documentation and no standalone pricing page; key API and model details are gated
