Crulon vs Smith.ai. An AI agent and a phone system.
Smith.ai answers the calls you forward to it. Crulon is the AI agent and the phone system together: you build the agent yourself on every plan, step into any call, hand calls to your team inside the same system, and pay by the minute, not the call.
Based on Smith.ai's pricing pages and help centers, 16 Oct 2026. Prices are for monthly billing.
Four differences that matter.
Most of a phone system is the same everywhere. These are the parts that aren't.
01
A phone system, not an answering service.
Smith.ai answers calls you forward to it from your phone system, so you keep paying for that system too.
Crulon is both: the AI agent answers, and phone menus, queues and team calling ring your people in the same place.

On Smith.ai's Free and Pro plans, custom AI prompting and custom integrations aren't included; they start at $500 a month, set up by Smith.ai.

Step into any call.
Live listen-in and takeover aren't anywhere in Smith.ai's documentation. You read the transcript afterwards.
On every Crulon plan you hear the AI's call without being heard, and take it over when it matters. Every listen-in is logged.

Questions about switching.
Is Crulon a Smith.ai alternative?
Yes, for teams that want the AI agent and the phone system in one place. Smith.ai answers calls you forward to it. Crulon answers on your own line, builds on every plan, lets you listen in and take over, and hands calls to your team in the same system.
Is Crulon cheaper than Smith.ai?
Usually, once calls add up. Smith.ai bills every answered call: $150 a month for 75 on Pro, then $2.50 a call. Crulon Starter is $24 a seat with 60 pooled AI minutes, then 25¢ a minute, so a three-minute call past the pool is 75¢. And Crulon's seat includes the phone system, which Smith.ai doesn't replace.
Does Crulon have live receptionists?
No. Crulon's AI agent answers, and hands the call to your own team with a note, inside the same system. If you need a human answering service, that's what Smith.ai is built for.
Can I build and change the agent myself?
Yes, on every plan. Write the agent's instructions, give it typed text, website pages and documents, connect your systems with Custom Actions, test it in the browser, and roll back any change.
Does Crulon speak Spanish?
Yes. The agent speaks eight locales across English, Spanish and French.
Can I keep my phone numbers?
On Scale, bring your own SIP trunk and keep your numbers for calls, with Crulon on top. Number porting is coming soon.
