3 GoHighLevel Alternatives for AI Calls and Messaging
Carly is our GoHighLevel alternative for businesses that want an AI to answer calls, text leads, handle WhatsApp and book customers using their own rules. Consider Close for a sales team’s CRM, or respond.io when managing messaging conversations is the main requirement.
HighLevel positions itself as an AI business operating system for capturing and nurturing leads through bookings and sales. Its offering includes AI voice. Switching because you want AI therefore requires a more specific reason: a better fit for your customer journey, operating model or setup preferences.
An agency managing client accounts is also making a different purchase from a local business trying to answer missed calls. This comparison focuses on the latter job: CRM and communication that help a customer reach the next step. It is Carly’s editorial assessment of public product information reviewed November 9, 2026.
What HighLevel users say about complexity
In a G2 review dated March 26, 2026, António M., a founder and physiotherapist, wrote, “The UI and UX are very complicated.” The 3/5 review also praised the social planner and AI chat and voice features, including ease of setting up AI chat. G2 marks it incentivized through its invitation program.
A separate June 3 review by data analyst Aditya P. gave HighLevel 5/5 while saying “the learning can feel a bit steep at first.” It praised the integrated CRM and automation. That review was also incentivized; HighLevel’s response acknowledged onboarding work.
These experiences support a question about administration, not a claim that HighLevel is unusable. Ask a colleague who will actually maintain your campaigns to change a booking rule, find a failed follow-up and explain which automation owns it. If one specialist currently understands the whole setup, migration may simply replace one training project with another.
HighLevel pricing includes an agency decision
HighLevel’s current pricing lists Starter at $97/month, Unlimited at $297/month and Founder at $497/month. The higher packages include agency capabilities such as white-label desktop access and, at the Founder level, SaaS reselling. Usage and optional services add to the subscription.
A three-person business using one pipeline is making a different purchase from an agency managing client accounts. Do not divide an agency subscription by seats and call that a complete comparison with Carly. Inventory the websites, forms, calendars, campaigns and client environments you use, then price the replacements as a group.
For example, removing HighLevel while keeping its client websites elsewhere may require hosting, form handling and migration work that a phone-agent subscription does not cover. If the agency functions generate revenue, retaining HighLevel can be the economical choice even when another product answers calls more appropriately for a particular client.
Which replacement can leave parts of HighLevel behind?
Carly belongs on the shortlist for a business delegating customer communication and appointments. Close is more relevant when representatives need a sales workspace. respond.io is more relevant when staff manage conversations across messaging channels. None of those descriptions establishes a substitute for HighLevel’s agency resale operation.
Choose the migration boundary before shopping: one client’s missed-call follow-up, the internal sales team’s CRM, or the entire agency platform. For a narrow move, record which workflows must stop in HighLevel and which remain active. Preserve the forms and campaign attribution you rely on until the new path has produced a correctly owned inquiry and a usable appointment.
Choose an alternative by the part of HighLevel you use
| Your main requirement | Shortlist | What to establish first |
|---|---|---|
| AI calls, messages and appointment handling | Carly | The instructions, calendar and escalation path |
| A sales team working leads and deals | Close | Rep workflow and reporting requirements |
| Customer conversations across messaging channels | respond.io | Channels, routing and human handoff |
| A platform operated across many agency clients | Evaluate HighLevel against that requirement | Client separation, administration and your service model |
1. Carly: a business assistant with calling and messaging
Carly handles phone, SMS, WhatsApp and email alongside a team CRM. You can give an agent a business number, configure what it should answer, connect a calendar and decide when a teammate should take over.
A useful first assignment is a new quote inquiry. The agent should collect the service needed, ask the questions that determine whether you can help, and book the right appointment. It should preserve the customer’s answers so the person preparing the quote does not start from scratch.
The value comes from your rules being explicit. “Offer weekday consultations, ask before changing an existing booking, and escalate pricing exceptions” is a better assignment than “grow sales.” Carly also connects to thousands of apps and works from ChatGPT, Claude, Grok Bot, Meta Muse and Perplexity.
Best fit: businesses buying help with customer conversations and follow-up. Free Zapier-style workflows; AI agents from $35/month. Organization starts at $35 per seat/month, with usage allowances to consider.
Carly cost and scope: Business SMS, calling and the AI receptionist are Organization add-ons billed separately from seats. Confirm channel availability and expected AI usage. Evaluate your required reporting, permissions and migration path before replacing an established CRM or phone system.
2. Close: keep salespeople in a sales workspace
Close is the alternative to evaluate when sales representatives and their calling queues are the center of the operation. It combines calling, SMS, email, workflows and reporting around a pipeline. It can be a sensible direction for an internal sales team that does not need to administer an agency’s client websites and marketing environments.
Its pricing matrix makes automation and dialer tiers explicit. Quote the package that covers the queue and follow-up your representatives actually use. Do not compare a basic CRM seat with every component of a HighLevel agency subscription.
Use a lead that replies by text after missing a call. The representative should see the context and the manager should see the outcome without rebuilding the sequence from several screens. Then check the report used to decide which leads need attention tomorrow.
Tradeoff: Close’s sales workspace is not a replacement specification for HighLevel’s funnels, websites or resale business. Keep a list of those functions and their owners if you move the sales team. A narrower tool helps only when the functions outside it have a clear home.
3. respond.io: organize customer messaging
respond.io is relevant when a team coordinates inquiries across messaging channels. AI agents, routing and a shared inbox address the conversation operation; your sales or agency records may still live elsewhere.
Its pricing page distinguishes the Growth automation offering from Starter and bills WhatsApp usage separately. Include active-contact volume and channel charges when comparing it with the communications portion of HighLevel. It should not be priced as though the subscription also replaces your website and campaign infrastructure.
Test an inquiry that arrives from an ad, moves between two colleagues and returns several days later. The second colleague should know the request, the owner and what was already offered. Ask how that outcome reaches whichever CRM remains authoritative.
Tradeoff: consolidating conversations is not the same project as consolidating an agency stack. This alternative is most compelling when missed assignments, inconsistent replies or unclear ownership are the operational issue. If your team already handles messaging well in HighLevel, another inbox may introduce reconciliation work without solving the original problem.
Price the workflow you are replacing
Write down the pieces you actually use: CRM records, business numbers, messages, AI work, calendars, forms and reporting. Compare the combined cost of that workload. A cheaper entry subscription does not establish that a replacement will be cheaper for your team.
If agency features are essential, ask each vendor to demonstrate client isolation and administration before moving anything. Carly’s customer communication features should not be treated as proof of equivalent agency resale features.
Prove one booking flow before moving every lead
Choose one service and a small test group. Run an inbound call, a text reply, a WhatsApp question and a cancellation. Inspect the customer record and calendar afterward. Keep the process narrow until you are satisfied with the answers and handoff.
Start with Carly’s calls, SMS and WhatsApp setup. For the messaging side, the WhatsApp CRM comparison covers the wider category.

Configure the customer conversation you want handled, then test it before expanding.
Help me connect Carly Teams so I can work with my organization's business texts, phone calls, voicemail and voice/text agents from this chat. I'll add it to you myself: tell me exactly what to click for the app you are, one step at a time, and wait for me to confirm before moving on. If a step doesn't match what I see, ask me what's on my screen. If you can do the setup yourself (Claude Code, Codex, Muse, Grok Bot), go ahead, and ask me for any key in your secure credential prompt, never in the chat. Don't tell me it's connected until list_phone_lines works, and if I have several teams, ask which to use. Before sending a text or making a call, confirm the team, recipient and message or task with me. The steps are below.
# Connect Carly Teams to an AI app
> Carly Teams works a team's business phone lines through the team's AI agents: business texts, phone calls, voicemail, the voice and text agents, and the team's CRM.
MCP server: https://carlyassistant.com/team/mcp (streamable HTTP, OAuth)
## Setup
Carly Teams isn't in any plugin or connector directory yet, so it's added as a custom connection by URL.
1. Add Carly Teams:
- ChatGPT: open https://chatgpt.com/plugins, click Add, and choose Create MCP App (not Create plugin or Upload plugin archive). If Create MCP App isn't on the menu, turn on Developer mode first in Settings > Security and login. Name it "Carly Teams" with the description "Work with my team's business texts, calls, voicemail and voice/text agents," paste https://carlyassistant.com/team/mcp as the server URL, choose OAuth, create it, and sign in. Then in the message box open the + menu, choose Developer mode, and pick Carly Teams. No plugin needs to be built, packaged or uploaded.
- Claude (claude.ai, Claude Desktop, or Cowork): Customize > Connectors > Add custom connector, name it Carly Teams, paste https://carlyassistant.com/team/mcp, and sign in.
- Claude Code: `claude mcp add --transport http --scope user carly-teams https://carlyassistant.com/team/mcp`, then /mcp, pick carly-teams, and authenticate.
- Codex: `codex mcp add carly-teams --url https://carlyassistant.com/team/mcp`, then `codex mcp login carly-teams`.
- Cursor: add {"mcpServers": {"carly-teams": {"url": "https://carlyassistant.com/team/mcp"}}} to ~/.cursor/mcp.json, then sign in to carly-teams from Customize.
- Muse: a custom connector to https://carlyassistant.com/team/mcp with a Carly API key as its bearer token. The key comes from carlyassistant.com/account (API key under Carly Teams) and goes in Muse's connector settings, not in a chat message.
- Grok: grok.com/connectors > New Connector > Custom, paste https://carlyassistant.com/team/mcp, and sign in.
- Grok Bot: a custom remote MCP server named carly-teams at https://carlyassistant.com/team/mcp. Approve it and sign in.
- Perplexity: Plugins in the sidebar (or Customize > Connectors), then Add custom > Connector > Add MCP connector. Choose Remote, name it Carly Teams, paste https://carlyassistant.com/team/mcp, pick OAuth, check the box and click Add, then click the Carly Teams card to sign in.
- Anything else: a remote MCP server (streamable HTTP) named carly-teams at https://carlyassistant.com/team/mcp. It signs in with OAuth.
Sign in with the Carly account that belongs to the organization.
2. Once it's added, the Carly Teams tools show up in the chat, including list_phone_lines. If they don't, turn Carly Teams on for the chat or start a new chat.
3. To check it worked, call list_phone_lines: it returns the teams and phone lines the account can reach. A team with no phone line yet can get one with find_numbers (optionally by area code) and get_number, which may return a checkout link to finish.
4. Something to try first: "Review our missed calls and voicemail and help me reply to customers." Carly Teams also reads and answers business texts, has the team's agent make calls, and edits the voice and text agents. Texts and calls go out at once from the agent's number and can't be taken back. Team permissions apply.
## Email, calendars and workflows
Email, calendars, files, booking pages and workflows are the regular Carly connector, added separately. It's listed in ChatGPT's plugin directory (https://chatgpt.com/plugins/plugin_asdk_app_6a67a26316b88191860222f918d4ec54) and Claude's connector directory (https://claude.ai/directory/carly), and connects anywhere else at https://carlyassistant.com/mcp/. Its setup is https://carlyassistant.com/mcp.txt.Want Carly answering your phones?
