Voice AI that feels real
Other platforms make you choose. Duplex gives you everything.
Instant Responses
170ms end-to-end latency. Conversations flow naturally without awkward delays or robotic pauses.
True Full-Duplex
Natural interruptions, backchanneling, and turn-taking. Just like talking to a real person.
Bring Your Own Everything
Use your own models (OpenAI, Anthropic), voices (ElevenLabs, Deepgram), or just use PersonaPlex.
MCP Tools Integration
Let your agents take real actions — search the web, query databases, call APIs, and more via Model Context Protocol.
Always Online
Your voice agents stay active 24/7. New users get welcomed, questions get answered, even at 3 AM.
