#2: Synthflow AI - Customizable AI Voice Agents
Synthflow AI is a general-purpose phone agent platform, similar to Bland AI. It advertises various use-cases and industries, such as real estate, recruitment and car dealership. While Bland leans towards positioning itself rather as a developer platform, Synthflow chooses a more user-friendly approach with a simple to use user interface and a lot of guidance, for instance in form of prompt templates for different call goals. While prompting becomes easier this way, the user still needs to touch prompts himself to adjust the AIs behaviour to their desired outcome. Additionally you have to bring your own Twilio account for making phone calls (in opposition to Setter AI and Bland AI) adding up the total cost per minute.
(+) When to choose Synthflow AI
- You want to customize the prompts and train the AI yourself to create complex conversation flows for different use-cases.
- You want to configure the phone calling services (here Twilio) yourself.
- You want to have access to a variety of prompt templates.
(-) When to not choose Synthflow AI
- You seek a flexible pricing option (lowest tier at $29 USD / month, next tier at $450 USD / month).
- You do not want to touch any prompt, do not work with a developer team and/or want to get started quickly.
- You don’t have a Twilio account and don’t want to configure the phone connection by yourself.
Key Facts
- Price tiers: $29 USD / month, $450 USD / month, $900 USD / month, $1,400 USD / month
- Whitelabel solution available for agencies
#3: Vocode - Open Source Option
Vocode is another general AI phone agents platform with a developer-centric focus. As the only tool on this list the code of their product is available open source, so it can be used for free when hosted by yourself. At the same time Vocode offers a paid hosted option too. It comes with a lot of flexibility and a broad API.
(+) When to choose Vocode
- Clear choice when in need of an open source option or self hosting is desired.
- You want to customize and configure deeper levels of the conversational AI (voice synthesis, LLM-streams, …).
- You want to test conversational AI at a low (financial) cost.
(+) When not to choose Vocode
- You do not want to touch any prompt, do not work with a developer team and/or want to get started quickly.

#4: Retell AI - LLM-Powered Voice AI
Similar to Synthflow AI and Vocode, Retell AI lets you customize certain technical components of the conversational AI (such as your phone provider and the LLM). They offer an API with broad functionality and put high emphasis on low latency. Again, technical knowledge is preferable and working with prompts is required to create AI phone agents with Retell AI.

- Up to 10 concurrent calls (on the non-enterprise plan)
#5: Air AI - Agency SaaS Platform
Air is a SaaS application that offers ready-to-use AI phone agents. Although Air was one of the first to introduce AI phone agents to the market, it has faced significant criticism from customers due to high upfront license fees and a no-refund policy.
Air AI's Trustpilot reviews may indicate some red flags. With only 2 out of 5 stars, users mention a not properly working service, long implementation times. Furthermore Air advertises itself as plug-and-play, however reviews say intensive coding knowledge is required to implement this software.
(+) When to choose Air AI
- You’d prefer to pay a high upfront fee than to pay as you go with other providers
- You are working with an agency that handles the setup and licencing for you
- You are an agency looking to resell an AI phone calling platform to your customers
