Platform comparison
Phone and WhatsApp AI agents, compared.
Most AI voice platforms stop at the phone. Your customers are on WhatsApp too — messaging, sending voice notes, and tapping call. Here is how Televox AI compares to Vapi, Retell, and Synthflow on the channels that actually reach your customers.
The problem
Most AI voice platforms only answer the phone.
The popular voice-agent platforms are excellent at phone calls — and stop there. That leaves the channel your customers use most every day uncovered.
Your customers are already on WhatsApp
Vapi and Retell have no native WhatsApp channel at all — you bolt it on with a Zapier or Make workflow, or go without. A workaround is not a channel: it adds latency, breaks when the automation does, and never handles voice notes or calls.
Voice notes go unanswered
On WhatsApp, customers often send a voice note instead of typing. No platform in this comparison documents transcribing a voice note and replying to it — so those messages sit unanswered, or a human has to listen and reply by hand.
A different tool for every channel
Running a voice platform for the phone, a separate widget for web chat, and yet another setup for WhatsApp means three configurations, three knowledge bases, and no shared memory of the customer across them.
Built for developers, not front desks
Vapi and Retell are API-first developer platforms — powerful, but you (or an engineer) build and maintain the agent. A local business that just wants its calls and messages answered needs a different starting point.
The solution
One agent. Every channel your customers use.
Televox AI runs a single AI agent across phone, WhatsApp, and website chat — from one knowledge base, built for local businesses rather than developers. On WhatsApp it answers text messages, transcribes and replies to voice notes in the agent's own voice, and (in beta) answers voice calls when a customer taps the call button — all on your existing number.
