Every provider below is connected from one place in the dashboard: Settings → Integrations. Use the Telephony, LLM, TTS, STT and Tools filters on that page to find a provider, then click Connect on its card.
Bolna doesn’t charge for usage on providers you connect yourself — you pay that provider directly. See Connect provider credentials for the step-by-step flow and the keys each provider needs, and Choosing providers to pick a transcriber, LLM and voice for your use case.
