Retell AI vs Chatley AI: Which AI agent platform fits your business

Retell AI vs Chatley AI: Which AI agent platform fits your business

Both platforms automate customer conversations. They’re built for different teams.

Retell AI is infrastructure for building custom conversational AI. Chatley AI is a packaged system for running business communication, voice, chat, messaging, lead capture, and appointment booking in one place.

This comparison breaks down where they overlap and where they diverge, so you can pick based on what your team actually needs to run.

At a glance

What is Retell AI

Retell AI is a conversational AI platform built for creating, deploying, and operating AI agents, with a strong focus on voice.

It gives teams tools to build phone agents, connect them to knowledge bases and external systems, handle calls, test conversations, and analyze performance.

Retell has expanded past voice. The platform now supports voice, chat, and SMS, so businesses can run conversations across channels.

Pricing reflects the infrastructure approach. Retell charges pay-as-you-go, roughly $0.07 to $0.31 per minute for voice, with separate charges for models, voices, telephony, and optional features.

That makes Retell a fit for companies that want control over how their AI agents are built and integrated.

What is Chatley AI

Chatley AI takes a business-first approach.

Its platform lets businesses build AI agents that answer and place calls, use business knowledge, capture leads, follow workflows, book appointments, send messages, and connect to external systems.

Agents can be configured with their own voice, behavior, knowledge base, phone number, and integrations. Businesses can build visual workflows for more complex call logic.

Chatley covers 3 areas of AI communication.

• AI voice agents

• AI chat agents

• AI messaging

The platform also includes workflow automation, analytics, integrations, lead capture, appointment management, and webhooks.

Chatley gives a business a system to automate customer interactions, rather than raw conversational infrastructure for a developer to build on.

AI voice agents

Both platforms take voice seriously.

Retell handles inbound and outbound calls, uses knowledge bases, connects to external tools during a call, and transfers calls. It’s built for workflows where the agent needs to interact with external systems in real time. Retell’s materials describe roughly 600 ms latency, aimed at natural conversation.

Chatley’s voice agents are configurable too. Each agent gets its own voice, behavior, phone number, knowledge base, and actions, and more complex logic runs through Chatley’s visual workflow builder.

Chatley supports inbound and outbound calling, though outbound depends on the plan. Pro is inbound only. Elevate and Premium include outbound.

Retell fits teams where voice AI is the core technology they’re building. Chatley fits teams that want voice as one part of a larger business workflow, for example: call comes in, agent qualifies the lead, books the appointment, notifies the team, and follows up.

AI website chat

Website chat matters as much as voice for companies generating leads through search, ads, social, or their own site.

Retell has expanded into chat and SMS alongside phone calls, for omnichannel conversational experiences.

Chatley offers AI chat agents alongside voice and messaging, with a stronger emphasis on turning conversations into business outcomes. Its hosted lead capture forms and webhooks send leads to a CRM, Zapier, or a custom endpoint.

Technical teams building conversational AI into a custom app should look at Retell. Businesses that want website conversations to produce leads, appointments, and follow ups get more out of Chatley.

SMS and messaging

A prospect might call, miss the agent, get a follow-up text, come back to the site, and book.

Retell supports SMS and chat messaging alongside voice, including follow up messages during or after a call.

Chatley supports inbound SMS through Twilio and positions messaging alongside voice and chat as part of one platform.

Retell’s messaging extends its conversational infrastructure. Chatley’s messaging fits into a broader lead generation and service operation.

Knowledge bases

Both platforms let agents pull from business information to answer questions accurately.

Chatley lets users attach knowledge bases so agents can answer questions about the company.

Retell supports knowledge bases and retrieval-based responses, and syncs that knowledge across voice, SMS, and chat.

Both platforms have this feature. The difference is how much control you need over the system around it. Retell gives more control to a technical implementation. Chatley gets an agent running on company information faster.

Workflows and automation

A basic chatbot answers questions. A useful agent takes action, for example: identifies why the customer called, asks qualifying questions, checks availability, books the appointment, sends a confirmation, and notifies the sales team.

Chatley provides a visual workflow builder for multi-step call logic. Workflows are visual flows that determine what happens at each step of a call.

Retell provides agent workflows too, through function calling, APIs, webhooks, and integrations with external systems.

A team with developers who want custom logic gets more from Retell. A team that wants to configure business processes visually, without building from scratch, gets more from Chatley.

Lead capture and qualification

Most businesses want an agent that generates revenue, not just conversation. That means capturing name, phone number, email, service interest, budget, location, and preferred appointment time.

Chatley builds lead capture directly into the platform, with hosted forms and real time webhooks that send leads to external systems.

Retell supports lead qualification too, through its agent infrastructure and integrations.

Chatley is built around turning conversations into leads and appointments. Retell gives you the infrastructure to build that system yourself.

Appointment booking

Instead of a receptionist asking what day works, morning or afternoon, does 3pm work, an AI agent collects the information and connects to scheduling infrastructure.

Chatley includes booked appointments and calendar integrations.

Retell supports appointment booking through integrations and function calling, and its AI receptionist materials describe scheduling directly.

Capability is close to a tie here. The choice comes down to whether you want a ready made workflow or a custom technical build.

Call monitoring and analytics

Once an agent handles real customers, you need to know if it’s working.

Chatley provides analytics on call volume, success rate, duration, and cost, plus live call monitoring that lets a person listen in, whisper to the AI, or take over a call.

Retell provides call analytics, transcripts, simulation testing, monitoring, and AI quality assurance.

Retell has the edge for technical monitoring and large-scale operations. Chatley gives business teams the visibility they need without the added complexity.

Integrations and APIs

Retell is built to plug conversational AI into other software, with API and webhook access and support for telephony and external tools.

Chatley supports integrations too, including APIs, webhooks, calendars, Twilio, and Zapier.

Retell suits developers, product teams, custom applications, complex CRM integrations, custom telephony, and enterprise infrastructure.

Chatley suits businesses, agencies, marketing teams, lead generation workflows, scheduling, and teams that don’t want to build everything themselves.

The mistake is picking a developer platform when your team doesn’t need developer-level control, or picking a simplified business platform when the application needs deep technical customization.

Ease of use

A developer looking at Retell’s APIs and customization sees flexibility. A business owner looking at the same options sees extra complexity to manage.

Chatley focuses on configuring agents, workflows, knowledge bases, phone numbers, lead capture, integrations, and analytics from a business workspace built around getting an agent live and connected.

Chatley wins on simplicity. Retell wins on technical flexibility.

Pricing

Retell AI pricing

Retell uses pay-as-you-go pricing. Voice agents run roughly $0.07 to $0.31 per minute, depending on models, voices, telephony, and features selected. Chat pricing is listed separately, and there are added charges for knowledge bases, AI quality assurance, PII removal, SMS, and extra concurrency.

Costs scale with actual usage rather than a fixed monthly fee.

Chatley AI pricing

Chatley uses subscription plans.

• Pro, $129 a month, 150 included minutes

• Elevate, $229 a month, 400 included minutes

• Premium, $399 a month, 800 included minutes

• Enterprise, custom pricing

Plans differ in phone numbers, concurrent calls, knowledge bases, outbound calling, support, and onboarding.

Retell’s usage-based model tracks consumption closely. Chatley’s subscription model is easier to budget since the fee and included usage are known upfront. Don’t compare $129 a month directly against $0.07 a minute. They’re different pricing structures. Calculate expected call volume, average call length, and feature needs before deciding.

Enterprise features and security

Retell’s enterprise plan includes dedicated infrastructure, role-based access control, custom SSO, custom compliance terms, high concurrency, and dedicated support, with references to SOC 2, HIPAA, GDPR, and PII redaction.

Chatley’s Enterprise plan includes custom integrations, SIP trunk integration, guaranteed uptime and SLA, 150+ concurrent calls, enterprise onboarding and support, and compliance options including SOC 2, HIPAA, and GDPR.

Retell has the stronger proposition for a technically sophisticated organization building conversational infrastructure. Chatley fits an organization that wants a managed platform with enterprise support and compliance options already built in. Verify actual compliance requirements against your specific contract, not a marketing page.

Retell AI vs Chatley AI for agencies

Agencies often want to deploy AI agents for dozens or hundreds of clients, not just their own business.

Chatley has a stronger agency and white label orientation, which fits SEO agencies, marketing agencies, lead generation agencies, automation agencies, web agencies, and SaaS resellers.

Retell can support agency work too, but its core strength is the conversational infrastructure itself, which matters most to agencies with technical resources building custom systems for clients.

Which one is better for small businesses

A small business usually needs a problem solved, not an AI infrastructure project. Missed calls, slow follow-up, an AI receptionist that books appointments, website visitors that never turn into leads.

Chatley’s business-focused approach fits these problems directly, combining voice, chat, messaging, lead capture, workflows, scheduling, integrations, and analytics in one platform.

Retell can support these use cases too, and its deeper customization pays off more once the business has a technical team to use it.

Which one is better for developers

This one leans toward Retell. Developers care about APIs, webhooks, custom functions, telephony, model selection, voice selection, latency, custom integrations, scalability, and deployment control.

Retell’s platform and pricing pages emphasize API access, webhooks, simulation testing, customizable LLM and voice options, telephony choices, and scalable concurrency.

Chatley still provides APIs, webhooks, integrations, and workflows, so it isn’t a no-code-only product. For a sophisticated conversational AI product built from scratch, Retell is the more direct fit.

So, which one should you choose?

Pick Retell AI if you need advanced voice AI, deep technical customization, developer APIs, complex integrations, custom telephony, high volume call automation, sophisticated agent workflows, advanced testing and monitoring, enterprise conversational infrastructure, or usage based pricing.

Pick Chatley AI if you need AI phone agents, website AI chat, AI messaging, lead capture, lead qualification, appointment booking, business workflows, customer follow up, practical analytics, a business friendly platform, or agency and white label opportunities.

Retell fits AI that’s becoming part of your technology stack. Chatley fits AI that needs to handle customer conversations and turn them into business outcomes without building the entire system yourself.
