FAQ

Common questions

Discord is live now with full voice channel support. Telegram, Slack, WhatsApp, and custom WebRTC are coming soon. Build your agent once and deploy it everywhere.
BYOM lets you use your own API keys for LLMs (OpenAI, Anthropic), TTS (ElevenLabs), and STT (Deepgram). You pay those providers directly and just pay Duplex a small platform fee. Great for cost control and customization.
