Limitations & when to consider alternatives

Known limitations

  • Paid subscription required for the published plans. The current pricing page lists Agency, Full SaaS Mode, and Enterprise plans rather than a permanent $0 plan.
  • API query length limit. The documented message API requires the query to be under 5,000 characters.
  • Usage-based charges. Chat messages and voice calls deduct usage charges from an agency or client wallet.
  • Agent and concurrency limits vary by plan. Plans include different numbers of chat agents, voice agents, and concurrent calls.
  • Native mobile and desktop apps are not documented. The official documentation describes web, messaging, API, and phone-channel deployments rather than native Stammer applications.

Look elsewhere when

  • You need a native iOS or Android app.
  • You need an official browser extension.
  • You need fine-tuning of model weights.
