Newo vs Retell AI

Newo

Newo packages phone and chat reception into one AI agent for businesses that live and die by missed calls -- dental offices, HVAC, salons -- with real appointment-booking integrations rather than just a chat widget. The metered pay-as-you-go pricing means cost scales with call volume, which is fair but makes the bill harder to predict than a flat seat-based tool.

Pros

• +Handles phone calls in addition to chat, not just a website widget
• +Claims sub-3-second pickup and unlimited simultaneous conversations
• +60+ languages with mid-conversation switching
• +25+ pre-built integrations with scheduling, CRM, and payment tools

Cons

• −Pay-as-you-go pricing makes monthly cost variable and harder to predict
• −No public developer API confirmed beyond the listed pre-built connectors
• −Company founding and headquarters details come from third-party sources, not the site itself

Retell AI

One of the more honest voice-agent stacks: the pricing page breaks out infrastructure, TTS and LLM cost per minute so you can predict a call's cost instead of guessing. Telephony choice is wide and the concurrency allowance is generous. The catch is that per-minute billing plus add-ons makes a busy contact centre expensive fast, and the cheap end of the range only holds if you pick the cheap models.

Pros

• +Per-minute cost broken down by voice infrastructure, TTS provider and LLM on the public pricing page
• +Telephony via SIP trunking, Twilio and Vonage plus n8n, HubSpot, Make and Go High Level integrations
• +20 concurrent calls included before any concurrency charge
• +Voice, chat and SMS agents share one platform and API
• +HIPAA path exists via a signed BAA covered in the terms of service

Cons

• −Cost per minute more than quadruples between the cheapest and most capable model combinations
• −Knowledge base, denoising, PII removal and branded caller ID are all metered extras
• −No flat-rate plan, so a spike in call volume lands straight on the invoice
