Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Deepgram

  • Pricing is entirely usage-based, so total cost can be harder to predict than flat subscription tools.
  • The Growth plan requires a minimum $4K/year commitment to unlock discounted rates.
  • Enterprise features and custom SLAs require a direct sales conversation rather than self-serve signup.
  • Some promotional per-minute rates are time-limited, meaning long-term pricing may differ from current promotional rates.

Parabola

  • The Basic plan allows 1 user and 1,000 credits with limited AI
  • No price is published for either the self serve or the business tier
  • Credits are consumed when agents run, and further credits are bought pay as you go
  • Role based access control, SSO, version history and SLAs all sit on the unpriced business plan
