What is the difference between SmartAlex and Retell?

SmartAlex is a configured voice agent platform. Receptionist, campaigns, CRM, billing all included. Retell is a voice AI builder that gives you primitives (call handlers, prompts, webhooks) you assemble into a product. SmartAlex is faster to ship; Retell is more flexible at the cost of build time.

Is SmartAlex cheaper than Retell?

SmartAlex is $99 per agent per month all-in for 250 minutes. Retell charges $0.07 per minute platform fee plus LLM and transcription costs, which typically lands customers at $0.15 to $0.25 per minute. For 1000 minutes per month, SmartAlex usually comes out 30 to 60 percent cheaper.

Can I migrate from Retell to SmartAlex?

Yes. We import your prompts, function-call definitions, and phone numbers in three steps. Pro plans include white-glove migration where our team handles the cutover for you.

Does SmartAlex use the same voice models as Retell?

Both platforms use frontier-tier voice models. SmartAlex picks the best fit per use case automatically; Retell exposes the choice to you. Voice quality is comparable on the same underlying provider.

Can I use my own LLM with SmartAlex?

Enterprise plans support BYO-LLM with OpenAI, Anthropic, and Google. Retell exposes that flexibility on every plan. If pinning a specific model is a hard requirement, ask us about Enterprise.

Which platform is better for white-label resellers?

SmartAlex includes white-label and multi-tenant support on Pro plans without bespoke quotes. Retell offers white-label on Enterprise tier only.

SmartAlex vs Retell AI

Retell sells building blocks for voice AI. SmartAlex ships the assembled product. Both run on similar voice models. But only one of them is something you can deploy this afternoon.

SmartAlex wins if you want a configured voice agent with CRM, campaigns, and billing already wired in.

Retell AI wins if you are building a custom voice flow from scratch and want low-level building blocks.

Why teams choose SmartAlex over Retell AI

Why teams choose SmartAlex over Retell for production voice agents.

Configured, not constructed

SmartAlex ships ready-to-use receptionist and outbound agents. Retell hands you call handlers, prompts, and webhooks that you compose yourself.

Native CRM and pipelines

Contacts, deals, campaign reports, call recordings, and voicemail all in one place. Retell expects you to push events into your own CRM.

Phone numbers handled

Buy, route, transfer, and log numbers from the dashboard. Retell leaves provisioning to you.

Predictable monthly billing

$99 per agent per month, all-in for 250 minutes. Retell's $0.07/min is on top of LLM/transcription costs that vary per provider.

Compliance ready

SOC 2, HIPAA, BAAs, tenant isolation, and call recording controls included. Retell offers compliance support but you operate the stack.

Real support

Dedicated humans on Pro plans, white-glove onboarding on Enterprise. Retell's support is mostly self-serve and Slack.

Honest take

When Retell AI is the better pick

Retell is the better choice if you are designing a highly custom voice flow that does not look like a receptionist, outbound campaign, or support agent. For example, an interactive voice game, a clinical screening flow with branching logic, or a research prototype. Their building-block approach gives you control points SmartAlex deliberately hides for the sake of speed.
