Assistable AI vs GoHighLevel Voice AI: Best Voice Agent

Last updated: October 23, 2026

Assistable AI is a white label voice and chat agent platform that plugs into GoHighLevel sub-accounts, while GoHighLevel Voice AI is the native AI phone agent built into every sub-account. For most agencies the native Voice AI is the cheaper, simpler start; Assistable makes sense when you want its model choice, SIP trunking and separate AI resale business.

This guide compares the best voice AI options for GoHighLevel: native Voice AI, Assistable, what HeyLevi actually does, and custom builds. It covers pricing checked on October 23, 2026, setup, compliance and which to pick. AutogenCRM deploys AI agents in GoHighLevel for clients, so the advice comes from real builds.

Which voice AI is best for GoHighLevel?

GoHighLevel’s native Voice AI is the best voice AI for most GoHighLevel users, because it lives inside the sub-account, uses the same calendar and contacts, and starts at $50 per month per location. Assistable AI is better for agencies building a dedicated AI product with custom models and their own phone carriers.

What is GoHighLevel’s native Voice AI?

GoHighLevel Voice AI is an AI phone agent built into each sub-account that answers calls, collects details, books appointments on GoHighLevel calendars and updates the contact record. It works on LC-Phone numbers and can also handle outbound calls and a website voice widget, all billed through the AI Employee plans.

• Where it lives: the agent is configured inside the sub-account, so calls, transcripts and bookings sit on the same contact as texts and emails.
• What it can do: answer FAQs from a knowledge base, capture name, email and phone, book on calendars, transfer calls and trigger workflows.
• Channels: inbound calls, outbound calls and the Voice AI widget on a website.
• Related agents: Conversation AI handles SMS, chat and social messages with the same knowledge base.

What is Assistable AI and how does it connect to GoHighLevel?

Assistable AI is a separate platform for building, selling and running AI voice and chat assistants, structured as workspace, sub-account and assistant to mirror GoHighLevel. Each Assistable sub-account matches one GoHighLevel sub-account by location ID and opens inside GoHighLevel through a custom menu link.

Assistable AI features

• Voice agents that answer calls, book appointments, transfer calls and leave voicemails.
• Per sub-account resources: phone numbers, knowledge bases, custom tools and a wallet balance for usage.
• Model choice: several language models and voice engines, including ElevenLabs voices.
• Bring your own carrier: SIP trunking lets you use your own numbers with no Assistable telephony fee.
• Agency tools: white labeling, multi-account management and usage rebilling on every agency plan.

How Assistable fits into a GoHighLevel account

Agencies import their GoHighLevel sub-accounts into an Assistable workspace and add the Assistable portal as a custom menu link in agency settings, so clients see it inside their GoHighLevel dashboard. The alternative is a direct connection per sub-account from the Assistable workspace.

The trade-off is a second system. Call data, wallets and assistant settings live in Assistable, so your team supports two platforms and two billing relationships instead of one.

Is HeyLevi a voice AI for GoHighLevel?

HeyLevi is not a voice agent. HeyLevi is a brand and content AI that builds a brand playbook and offer playbooks, then writes social posts, emails, SMS sequences, ads, sales pages and images. It is sold to HighLevel agencies with a white label option, which is why it appears in voice AI searches.

• What it does: marketing copy and images in a consistent brand voice, using over 60 built-in copy frameworks.
• What it does not do: its site does not mention answering calls, outbound calling or appointment booking.
• Pricing: a free plan, Starter at $79 per month and Pro at $249 per month with five sub-accounts, with lower prices on annual billing.

If you need an AI that talks to callers, HeyLevi will not replace Voice AI or Assistable. It can sit beside them to write the nurture messages your workflows send.

What other voice AI options work with GoHighLevel?

Developer voice platforms such as Vapi and Retell AI can connect to GoHighLevel through the API and webhooks. They give full control over call logic, voices and models, but someone must build and maintain the integration, map data into custom fields and handle errors when either side changes.

• Marketplace apps: several white label voice AI apps install from the GoHighLevel Marketplace and add a branded dashboard inside the sub-account. Check who owns the data and the phone numbers before you commit.
• Custom builds: worth it only when the native agent cannot handle your call flow, such as multi-step qualification across several systems.
• Classic dialers: if you need humans on the phone rather than AI, the GoHighLevel dialer may be the better tool.

How much does voice AI for GoHighLevel cost?

GoHighLevel Voice AI costs $50 per month per location with 100 minutes included, $97 per month for fair-use unlimited, or pay-per-use from a $0.045 voice engine rate plus voice, model and phone charges. Assistable AI costs $225 to $975 per month plus about $0.09 per minute in its own example.

GoHighLevel Voice AI pricing

HighLevel’s AI product pricing article lists three options per enabled location.

• Voice options on pay-per-use: OpenAI and Cartesia voices add $0.015 per minute, ElevenLabs V2.5 adds $0.035 and ElevenLabs V3 adds $0.170.
• Speech-to-speech models: priced all-in at $0.10 per minute for Gemini 3.1 Flash Live Preview and $0.20 for OpenAI’s realtime model.
• Always extra: phone system charges on every call, and Agent Studio, which is pay-per-use on every plan.

Our GoHighLevel AI Employee pricing guide works through when Growth or Unlimited beats pay-per-use.

Assistable AI pricing

Usage is billed on top: $0.05 per minute for orchestration, $0.07 to $0.15 per minute for the voice base depending on the voice, $0.0075 to $0.05 for the language model, and $0.015 for Assistable telephony or nothing on your own SIP trunk. Assistable’s own example totals $0.09 per minute before add-ons, and calls under 10 seconds add $0.015.

What actually drives your voice AI bill

• Voice choice: premium voices can cost more per minute than the engine itself.
• Prompt and knowledge base size: longer prompts mean more tokens per minute on token-billed models.
• Call length: agents that ramble or loop on unclear answers burn minutes, so tight scripts save money.
• Subscriptions: Assistable adds a platform fee on top of your GoHighLevel plan; native Voice AI does not.

What compliance rules apply to AI voice calls?

AI voice calls in the US fall under the Telephone Consumer Protection Act, and the FCC ruled in 2024 that AI-generated voices count as artificial voices. Outbound AI calls therefore need prior express consent, and texts sent around those calls need A2P 10DLC registration.

• Inbound calls: lower risk, since the caller contacted you. Still disclose that the caller is speaking with an AI assistant.
• Outbound calls: HighLevel requires registration and approval before you can use outbound Voice AI, and you need documented consent for every number you call.
• Texting: follow-up SMS from local numbers must run on a registered brand and campaign. We handle GoHighLevel A2P 10DLC registration for US businesses.
• Recording: some states require all-party consent to record calls, so add a recording notice to the greeting.

Which voice AI should you pick for GoHighLevel?

Start with GoHighLevel’s native Voice AI if you need an AI receptionist, booking agent or follow-up caller for one business or a handful of clients. Choose Assistable AI if AI agents are a product line you sell to many clients and you need model choice, SIP trunking and separate rebilling.

1. Define the job. Answering and booking calls suits native Voice AI. Complex multi-system qualification may need Assistable or a custom build.
2. Count the locations. Native plans bill per location; Assistable bills a platform fee plus usage across all accounts.
3. Check your carrier. If you already own numbers on a SIP trunk, Assistable can avoid a telephony fee.
4. Weigh support load. One platform is simpler to train staff on and troubleshoot than two.
5. Pilot one account. Run real calls for two weeks, read transcripts and fix the prompt before rolling out.

If you resell AI under your brand, our GoHighLevel white label setup and guide to SaaS mode rebilling explain how to charge clients for AI usage with a markup. New to the platform? You can test Voice AI on a 30-day free trial (partner link) instead of the standard 14 days.

AI agent sounding robotic or not booking calls?

Most voice AI failures in GoHighLevel come from setup, not the model: vague prompts, a thin knowledge base, calendars with wrong availability, or no handoff when the caller asks for a person. Fixing those usually matters more than switching platforms.

Our GoHighLevel setup service builds and tunes AI Employee agents end to end: the prompt, knowledge base, calendar rules, call transfers and the follow-up texts, so your agent books real appointments instead of frustrating callers.

Frequently Asked Questions

Is Assistable AI worth it for GoHighLevel agencies?

Assistable AI is worth it for agencies that sell AI agents as a separate product to many clients and want model choice, SIP trunking and built-in rebilling. For a single business or a few clients, GoHighLevel’s native Voice AI is usually cheaper, because it avoids Assistable’s $225 or higher monthly platform fee.

Does GoHighLevel have its own voice AI?

Yes. GoHighLevel Voice AI is built into every sub-account and answers inbound calls, makes outbound calls and runs a website voice widget. It books on GoHighLevel calendars, captures caller details and triggers workflows. It is billed per location through pay-per-use or the $50 Growth and $97 Unlimited AI Employee plans.

How much does GoHighLevel Voice AI cost per minute?

On pay-per-use, GoHighLevel Voice AI charges a $0.045 per minute voice engine fee, plus text-to-speech from $0.015 per minute, language model tokens and phone system charges. Speech-to-speech models are priced all-in at $0.10 or $0.20 per minute. The Growth plan includes 100 minutes for $50 per month.

Can GoHighLevel Voice AI make outbound calls?

Yes. GoHighLevel Voice AI supports outbound calls, and its Growth and Unlimited plans count outbound minutes alongside inbound and widget minutes. HighLevel requires you to register and be approved before using outbound Voice AI, and US rules require prior express consent for AI-voice calls to each number.

What is HeyLevi used for?

HeyLevi is used to create on-brand marketing content. It builds a brand playbook and offer playbooks, then writes social posts, emails, SMS sequences, ads, sales pages and images. It is sold to HighLevel agencies with a white label option, but it is not a phone or voice agent.

Should I use native Voice AI or an add-on?

Use native Voice AI when you want one system for calls, texts, bookings and contacts with the least setup and support. Use an add-on such as Assistable when you need specific models or voices, your own SIP carrier, or a separate AI resale business with its own wallets and billing.
