Where each one falls short

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

Amazon Lex

  • Pay-as-you-go model with no standard free tier, only AWS free credits for new customers (6 months, $200 limit)
  • Speech requests cost $0.004 each, text requests $0.00075 each, training costs $0.50 per minute
  • Variable costs can accumulate quickly for high-volume applications

UserVoice

  • No tier names, prices or billing cycles are published on the pricing page; every call to action reads Talk to an Expert rather than showing a figure
  • Pricing is based on feedback volume and which integrations are connected rather than a flat seat price, so cost cannot be estimated without a sales conversation
