## What is Clack?

Clack is the messenger for your self-hosted OpenClaw AI Agent. Chat by text, talk by voice — across multiple private conversations, all stored on your own server.

No middleman. No cloud relay. No account required.

HOW IT WORKS Clack connects directly to your OpenClaw AI gateway. Send a text message or start a hands-free voice call — switch between both anytime. Every conversation is stored on your server and synced across sessions.

VOICE & TEXT IN EVERY CHAT Talk naturally with real-time voice calls and automatic silence detection. Or type when you prefer. Tiny icons show which messages were voice and which were text, so you always know how a conversation happened.

MIX AND MATCH VOICE PROVIDERS 
Choose speech-to-text and text-to-speech independently: 
• ElevenLabs — premium natural voices 
• OpenAI — reliable and fast 
• Deepgram — low-latency specialist 
• On-device (Apple) — free, works offline

Save money by using free on-device transcription with premium cloud voices, or go fully local for zero API spend.

### 4/5 — Works welll

*2026-03-25*

Easier to set up and actually works unlike other apps that try the same.  Can we set our own custom voices as I only see options for the defaults.

**Developer response:** Thank you for your review! Currently, only default voices are available per provider but I will note it as a feature request to add custom voices. I hope you enjoy using the app!
