Synthflow vs Air AI - Which one is best for you? (2024)

‍

#1: Synthflow AI - Customizable AI Voice Agents

Synthflow AI is a versatile phone agent platform, similar to Setter AI. It promotes a variety of use cases across different industries, such as real estate, recruitment, and car dealerships. While Setter positions itself as a developer platform, Synthflow offers a more user-friendly experience with an easy-to-use interface and plenty of guidance, including prompt templates for different call objectives. This makes prompting simpler, but users will still need to adjust prompts themselves to fine-tune the AI's behavior to their desired outcomes. Additionally, you need your own Twilio account for making phone calls, which adds to the overall cost per minute.

(+) When to choose Synthflow AI

• You want to customize prompts and train the AI yourself for complex conversation flows across different use cases.
• You prefer to configure phone calling services (such as Twilio) yourself.
• You want access to a variety of prompt templates.

(-) When to not choose Synthflow AI

• You need flexible pricing options (lowest tier is $29/month, next tier is $450/month).
• You don’t want to handle prompts, don’t work with a developer team, or need a quick start.
• You don’t have a Twilio account and don’t want to set up phone connections yourself.

Key Facts

• Price tiers: $29/month, $450/month, $900/month, $1,400/month
• Whitelabel solution available for agencies

#2: Air AI - Agency SaaS Platform

Air AI is a SaaS application offering ready-to-use AI phone agents. Although it was one of the first to introduce AI phone agents to the market, it has faced significant customer criticism due to high upfront license fees and a no-refund policy. Trustpilot reviews indicate some issues, with only 2 out of 5 stars. Users mention a poorly functioning service and long implementation times. Although advertised as plug-and-play, reviews suggest that substantial coding knowledge is required for implementation.

(+) When to choose Air AI

• You prefer to pay a high upfront fee rather than a pay-as-you-go model.
• You work with an agency that handles the setup and licensing for you.
• You are an agency looking to resell an AI phone calling platform to your customers.

(-) When to not choose Air AI

• You don’t want to pay an upfront fee of $25,000-$100,000.
• You don’t want to be locked into a mandatory commitment period with their SaaS platform.
• You want to avoid the hassle of coding or integrating APIs.

Key Facts

• One of the first AI phone agent applications
• Starting fee ranges from $25,000-$100,000 for agency license holders
• Predominantly negative customer feedback
