Integrations

The plumbing is already done.

Missing a provider?

Tell us. Adding a new STT, TTS, or LLM is usually a one-week ticket because the orchestrator talks to all of them through one adapter interface. Customer-data connectors take longer (we have to model your schema). Email us at hello@callfunnel.ai.
