Frequently asked
Isn't Callsy built on ElevenLabs?
Partially, yes. ElevenLabs is one of Callsy's voice sub-processors — many of our 50+ voices are powered by ElevenLabs neural TTS. Callsy is the layer above: telephony, agent orchestration, conversational state, workflows, MCP, CRM. You could build Callsy on top of ElevenLabs + Twilio + Deepgram + your own orchestration, or you could use Callsy.
So should I just use ElevenLabs Conversational AI?
If all you need is voice chat on a webpage or inbound browser-based voice, ElevenLabs Conversational AI can be enough. If you need real outbound phone calls, SMS, contact management, multi-step workflows, CRM, or MCP integration with Claude / GPT — you'll end up building Callsy.
Can I bring my ElevenLabs voice to Callsy?
Yes. Callsy supports bringing your own ElevenLabs voice ID for custom or cloned voices, including voices you've cloned on your own ElevenLabs account. Contact support@callsy.ai for setup.
Which is better for non-English?
Both are strong. Callsy ships real ElevenLabs samples for 9+ languages out of the box (English, Polish, Arabic, Spanish, French, German, Italian, Portuguese, Hindi) with more on request. ElevenLabs itself supports 30+ languages for TTS, but you'd still need to wire the call around it.
Is Callsy cheaper than ElevenLabs?
They're not directly comparable. ElevenLabs charges per character of TTS. Callsy charges per call (or free tier). If you're placing real phone calls, Callsy's flat monthly typically costs less than the ElevenLabs-plus-infrastructure sum.
