What each one is

GoHighLevel Voice AI is a voice agent built into the GoHighLevel platform. It answers and places calls, follows a script and a knowledge base, books appointments into your calendars, and updates contact records. You set it up in the dashboard, not in code.

Retell is a developer-focused platform for building voice agents. It gives you APIs and tools to design the call pipeline, connect models, and handle real-time conversation, then you build and host the logic. It is flexible and fast for engineers, but it expects code.

Setup and build effort

With GoHighLevel, you configure the agent in the dashboard: write a prompt, add a knowledge base from your business info, connect a calendar, and assign a phone number. A non-developer can launch a working booking agent the same day.

With Retell, you build the agent through its API and dashboard, define the conversation flow and functions, and connect your own backend for anything beyond the call itself. That control suits product teams but needs engineering time.

CRM and follow-up

The GoHighLevel agent sits next to your contacts. It can read a caller record, write notes, tag the contact, and trigger a workflow after the call, such as a confirmation text or a nurture sequence, with no glue code.

Retell does not include a CRM. You connect your own database or CRM through function calls and webhooks, and you build the follow-up yourself. Good for a custom build, slower for a typical service business.

Telephony and phone numbers

GoHighLevel includes its own phone system. You buy numbers inside the platform, and calls, texts, and the voice agent all run through it, billed by usage.

Retell connects to a telephony provider such as Twilio. That gives you provider choice and control, but it is another account to set up and bill alongside the agent.

Model and voice control

Retell gives developers control over the call pipeline, including how speech, language, and voice models fit together and how the agent handles real-time turns. If low latency and tuning matter for your product, that control helps.

GoHighLevel manages the model stack inside the platform. You shape the agent through the prompt and knowledge base rather than tuning the pipeline. Less control, much less to maintain.

Pricing

GoHighLevel plans start at $97 per month, and voice AI is billed by the minute on top of the plan along with email, SMS, and other AI usage. The CRM, calendars, and workflows are in the same bill.

Retell bills voice usage by the minute, and you also pay your own telephony and any model costs. We do not quote a number because it changes. Check retellai.com for current rates and add your provider costs.

Who should choose each

Choose Retell if you are a developer or product team building a custom voice agent and you want control over the call pipeline, models, and integrations.

Choose GoHighLevel Voice AI if you run an agency or a local business and want a phone agent that books appointments and updates your CRM without code, inside the platform you already use to run the business.

How to switch from Retell to GoHighLevel Voice AI

Start a 30-day GoHighLevel trial through RocketLauncher. Take the prompt and conversation goals you built in Retell and recreate them in the GoHighLevel agent, then load a knowledge base from your business information.

Connect a GoHighLevel calendar so the agent can book, assign a phone number, and run a few test calls. Once booking and follow-up work, point your live number at the GoHighLevel agent and retire the custom Retell setup. You trade pipeline control for a much shorter build.

Via RocketLauncher you get 30 days. Direct signup gives 14. No credit card to start.
