Retell AI is a platform for building AI voice agents that answer and make phone calls. We scope what your agent should handle, connect it to your phone number, calendar, and CRM, build the knowledge it answers from, and test it before your customers hear it.
Retell gives you the building blocks of an AI phone agent: phone numbers, voices, call flows, call transfers, appointment booking through Cal.com and Calendly, a knowledge base, and connections to CRMs such as HubSpot, Salesforce, and Zoho. That flexibility is why it fits a business with a call process of its own.
It also means someone has to design the agent, wire up the connections, register numbers for texting, and test what happens when a call goes wrong. Retell offers dedicated implementation support only on its Enterprise plan. For a small business, that work is what we do.
We map the calls you get today, decide which ones the agent handles and which go straight to a person, and define what a good outcome looks like for each before anything is built.
We route your existing number to the agent through your phone provider or set up a new one, connect booking through Cal.com or Calendly, link your CRM, and build custom connections where no built-in one exists.
We load the agent's knowledge base with your services, service area, hours, and policies, and write clear rules for what it must never promise, so answers come from approved information.
We run realistic test calls, including transfers and failed bookings, set up call summaries so your team sees every outcome, and train staff to review calls and keep the agent current.
No. Retell is a platform for building voice agents. It provides phone numbers, voices, transfers, booking, and integrations, but the call flow, knowledge, and connections have to be designed and tested for your business. That is the part we handle.
Yes, through your phone provider. Retell connects to providers such as Twilio, Telnyx, and Vonage, so your existing number can send calls to the agent. We confirm the right setup with you before changing anything customers already use.
Yes, with setup. Retell supports two-way texting on U.S. numbers once the number completes carrier registration for business texting, which Retell says takes around two to three weeks. We work through that registration with you.
Retell bills pay as you go by the minute, with separate charges for the AI model, voice, and phone line, optional add-ons, and monthly fees for numbers and texting. Prices change, so we estimate your monthly cost from your actual call volume during scoping.
No. You open your own Retell account and pay Retell directly. We provide the design, setup, connections, testing, and training as our own separate service.
No. We also set up GoHighLevel AI Employee, Smith.ai AI Receptionist, and Sameday, along with team AI platforms such as ChatGPT Business, Claude Team, Microsoft 365 Copilot, and Gemini, and we help businesses choose and connect other AI tools as well. We recommend the platform that fits how your business already works, and if your current tools can do the job, we will tell you that instead.
We decide that with you before rollout. We limit each connection to the access it needs, organize the documents the AI should draw on into approved knowledge sources, and review file sharing so people only see what they are meant to see.
No. Our training is built for owners, operators, and staff with little or no technical background, using your own work as the examples.
