The trade-offs

Strengths and Limitations

Cartesia

Strengths

  • Lowest-latency real-time voice for agents
  • Instant three-second cloning
  • Cost-effective developer API

Limitations

  • Less expressive on long-form and audiobook content
  • Newer and developer-oriented

Granola

Strengths

  • No bot joins the call, so nothing appears in the attendee list
  • Expands shorthand typed during the meeting instead of replacing note-taking
  • AI chat runs across the whole meeting history, not a single transcript
  • Opt-out of model training on every plan, including the free one
  • MCP server and API on Business, so meeting context reaches other AI tools

Limitations

  • Capture depends on a machine being in the meeting, since it records local computer audio
  • The free plan limits how far meeting history reaches back
  • Integrations, API and MCP start on the Business plan
