Both pages checked by August 19, 2026
- NexaAI + human backup
- Pricing not published
- no published plan
- People-powered 24/7 call answering, client intake, inbound and outbound sales and live chat/text service for home services, healthcare, legal and real estate businesses, with an optional Voice + AI agent that can hand calls off to human agents.
- VapiAI only
- Pricing not published
- no published plan
- Developer platform for building voice AI agents: Vapi hosts the orchestration layer and charges a per-minute hosting fee, while you pick and pay for your own speech-to-text, LLM, text-to-speech and telephony providers and write the assistant, tools and server hooks yourself.
The differences that matter
- Nexa is ai + human backup; Vapi is ai only. That is the real decision here, not the price.
- Nexa can put a human on the line; Vapi is bot-only.
