Calldesk AI vs Poly AI (Tried, Compared) – Which is best?

Calldesk AI - a quick overview

‍

‍

Founded in Paris, France in 2015 by Vincent Gire and Aimé Dushimire, Calldesk is a pioneering conversational AI company that transforms customer service through AI-powered voice agents. Their innovative platform automates repetitive customer service calls with AI IVR, AI Receptionist, and AI Answering Service, allowing businesses to focus on high-value interactions while reducing operational costs and improving customer satisfaction.

‍

With notable clients including La Poste, MGEN, Enedis, and CNP Assurances, Calldesk has established itself as a leader in the rapidly growing call center AI market. Their technology supports 54 languages and achieves impressive success rates of up to 95% for simpler use cases. In the following section, we'll explore Calldesk's features, pros and cons, pricing, and user reviews compared to Poly AI and Ringly.io.

Calldesk AI's features

• AI Voice Agents for Customer Service
  Calldesk automates repetitive customer service calls using AI voice agents, handling tasks like answering FAQs and routing calls. This boosts productivity by freeing up human agents for complex issues. While Poly AI also offers conversational automation, Ringly.io goes further by integrating real-time business data and custom actions during calls, making it more dynamic for e-commerce and support.
• Natural Language Processing (NLP)
  Calldesk’s advanced NLP enables smooth, natural conversations with callers—even in noisy environments or with diverse accents—ensuring accurate understanding without rigid menus. Poly AI is similarly strong in NLP, but Ringly.io leverages this to pull precise answers from your own knowledge base instantly, reducing misinformation and improving trust.
• Quick Deployment via Studio Platform
  The ergonomic Studio platform allows businesses to deploy Calldesk voice agents within days rather than months. This rapid setup is similar to Poly AI’s fast onboarding but lacks the instant “just works” integration of Ringly.io’s knowledge base sync that updates daily without manual training.
• AI IVR & Receptionist Automation
  Calldesk digitizes inbound call interactions through automated IVR (Interactive Voice Response) and receptionist services. It efficiently processes simple requests end-to-end or partially before escalating complex cases—a feature also found in Poly AI. However, Ringly.io adds smart call transfer with detailed context summaries so teams only handle relevant escalations.
• Cost Efficiency & Scalability
  By automating high-volume repetitive tasks 24/7, Calldesk reduces cost per call and absorbs spikes in demand seamlessly—similar to both competitors. Yet unlike Ringly.io’s abandoned cart recovery automation that directly drives revenue growth for e-commerce stores while saving on support costs, Calldesk focuses mainly on operational savings.
• High Understanding Rate in Challenging Scenarios
  Best-of-breed architecture ensures high comprehension even when callers have heavy accents or there is background noise—minimizing errors during conversations. While this matches industry standards set by Poly AI as well, it doesn’t offer the same level of real-time order lookups or personalized responses based on live business data as seen with Ringly.io.

In summary: Calldesk excels at automating routine phone interactions quickly and accurately for general customer service needs but lacks deep integration with live business systems (like order status checks or CRM updates) that make solutions like Ringly.io uniquely powerful for businesses seeking not just efficiency—but smarter revenue-driving automation too.

Calldesk AI Pros and Cons

• User-friendly interface – Many users highlight that Calldesk AI is intuitive and easy to use, even for those without much technical experience.
• Fast setup and smooth implementation – Reviewers often mention that getting started with the platform is quick, with minimal friction during onboarding.
• Effective automation – The system handles routine customer queries autonomously, freeing up human agents for more complex tasks.
• Real-time customer support access – Users appreciate being able to reach support quickly when needed; however, most find they rarely need it due to the product’s ease of use.
• Versatile applications – The platform supports a wide range of use cases (e.g., marketing creativity tools, video creation), making it adaptable across industries.
• Strong natural language processing (NLP) capabilities – Several reviewers note that its NLP features enable successful completion of many interactions without agent intervention.
• Enhances team productivity – By automating repetitive tasks and streamlining workflows, teams can focus on higher-value activities.

Cons

• Notification overload – Multiple users report that automated notifications can be excessive or distracting until they become accustomed to the system settings. Ringly.io’s notification management may offer a more streamlined experience here.
• Occasional glitches or bugs – Some reviewers have experienced minor technical issues during processing or screen recording quality problems; these typically require updates or fixes from the vendor.
• Limited integrations with third-party tools (e.g., Adobe, Canva) – Users mention challenges in connecting Calldesk AI seamlessly with other popular software platforms used in their workflow. Ringly.io emphasizes broader compatibility as a differentiator in this area.
• Lack of local language options for some regions – There are requests for expanded language support so smaller organizations in non-English-speaking countries can benefit fully from the solution. Ringly.io’s multilingual capabilities may address this gap.
• Product best suited for small/medium businesses only — Some feedback suggests larger enterprises might find limitations compared to their needs; scalability could be an issue as organizations grow beyond SMB size brackets.
• No dark mode option yet — A few users would prefer additional UI customization such as dark mode backgrounds but note this is not currently available out-of-the-box.

These insights reflect what real customers are saying about using Calldesk AI day-to-day—highlighting both where it shines and where there’s room for improvement.

Poly AI - a quick overview

‍

‍

Founded in London in 2017 by Nikola Mrkšić, Tsung-Hsien Wen, and Pei-Hao Su, PolyAI builds AI-powered voice assistants that transform customer service through natural, human-like phone interactions. The company serves Fortune 500 clients like FedEx and Marriott with its conversational AI technology, which handles high call volumes while reducing operational costs.

‍

In the following section, we’ll break down PolyAI’s features, pros and cons, pricing models (where available), and user reviews compared to Calldesk AI and Ringly.io. This comparison will help identify where each solution stands for businesses seeking advanced voice automation tools.

Poly AI's features

• Advanced Conversational AI
  Poly AI delivers highly natural, lifelike voice interactions using proprietary speech recognition and synthesis models. Its platform is pre-trained on billions of real customer conversations, allowing it to understand intent and context without extensive custom training. This makes Poly AI ideal for enterprises needing scalable, human-like automation in high-volume call environments. While Calldesk also offers strong NLP capabilities, Poly AI’s focus on nuanced dialogue management often results in more flexible and realistic conversations—though it lacks the deep e-commerce integrations found in Ringly.io.
• Seamless Integration with Existing Tech Stacks
  Poly AI integrates smoothly with enterprise systems such as CRMs and contact center platforms. It uses real-time spoken language understanding (SLU) to correct errors from speech recognition engines, ensuring accurate data capture during calls. This is comparable to Calldesk’s CRM integration but stands out for its ability to “fix” faulty transcriptions mid-conversation. However, unlike Ringly.io—which provides no-code connections for instant setup across thousands of business tools—Poly AI may require more technical resources for full customization.
• Transaction Handling & Authentication
  The platform can authenticate callers using voice biometrics or multi-factor methods and complete transactions directly within the call flow. This capability is valuable for industries like banking or travel where secure self-service is critical. Calldesk supports similar transactional flows but typically relies on standard IVR logic rather than advanced authentication layers. For e-commerce use cases like abandoned cart recovery or order status checks—which are handled natively by Ringly.io—Poly AI would need additional configuration.
• Flexible Dialogue Management
  Poly AI employs a patented approach that lets customers navigate conversations naturally instead of following rigid scripts. Users can change topics mid-call or ask follow-up questions without confusing the system—a significant advantage over traditional IVR solutions like those offered by some competitors. While Calldesk allows customizable workflows, its flexibility may not match Poly’s open-ended conversational design; however, neither solution matches the out-of-the-box workflow automations tailored specifically for online stores that Ringly.io provides.
• High Call Resolution Rates
  With up to 50% of customer service calls resolved end-to-end without human intervention, Poly AI reduces operational costs while improving response times in large-scale deployments. Calldesk achieves similar automation rates but tends to focus more on inbound routine queries rather than complex transactional support. In contrast, Ringly.io combines high-resolution rates with specialized features (like SMS follow-ups and smart transfers) designed specifically to drive sales conversions—not just resolve support tickets.
• Industry-Specific Pretraining
  Poly AI’s models are trained across sectors such as hospitality, logistics, finance, and utilities, making them well-suited for organizations seeking rapid deployment without lengthy onboarding periods. While this broad applicability benefits enterprises with diverse needs (similar to Calldesk), businesses looking for hyper-focused e-commerce functionality will find purpose-built solutions like Ringly.io better aligned with their goals.

In summary: Poly AI excels at delivering flexible conversational experiences at scale through advanced language technology and seamless integrations—but when it comes to specialized commerce automations (cart recovery calls or live order tracking), dedicated platforms offer a clear edge in both speed-to-value and ease of use.

Next, let's look at Poly AI's pros and cons. We studied dozens of reviews from real Poly AI users from platforms like G2, Capterra, and TrustRadius. Then we identified commonalities and summarized the main pros and cons of Poly AI based on real user feedback for you here:

Pros

• Exceptional call automation – Users consistently praise PolyAI’s ability to automate client calls efficiently, freeing up staff time for higher-value tasks.
• User-friendly interface – The platform is noted for its simple setup and intuitive design, making it easy to use even for non-technical teams.
• Lifelike voice quality – Many reviewers highlight the human-like quality of PolyAI’s voice assistant, which avoids sounding robotic and enhances customer engagement.
• Seamless integrations – Businesses appreciate how easily PolyAI integrates with existing software systems such as CRMs or calendars without major technical hurdles.
• High-quality customer support & collaboration – The support team receives strong marks for responsiveness and willingness to tailor solutions to specific business needs. Ringly.io also emphasizes hands-on onboarding but takes pride in offering more transparent pricing.
• Rich data insights & analytics dashboard – Users value the analytics features that provide actionable insights into call trends, customer inquiries, and operational performance. This helps businesses refine their strategies over time.
• Tangible ROI improvements in key sectors (like hospitality) – Several reviews mention improved call answering rates during staffing shortages or off-hours—delivering measurable ROI by reducing missed opportunities. Ringly.io similarly focuses on maximizing efficiency but also offers more flexible reporting options.
• Bespoke customization options available – Reviewers note that PolyAI can be tailored closely to brand identity while maintaining consistent service levels across locations or departments.

Cons

• Lack of advanced voice analytics features – Multiple users wish for deeper sentiment analysis or more granular conversation data; current analytics are seen as somewhat basic compared to what some teams need for continuous improvement.
• Difficulties handling complex scenarios – While routine queries are handled well, some reviewers report that nuanced conversations or multi-part questions may confuse the system—sometimes requiring human intervention.
• User acceptance challenges (perceived rudeness/impersonality) – Some customers remain skeptical about interacting with an AI assistant; unfamiliarity can lead them to perceive responses as impersonal—even when following a script.
• No anonymous feedback option in surveys/conversations (for internal use cases) – For organizations wanting truly candid input from staff/customers via surveys or open-ended prompts within the platform itself, anonymity is hard to achieve.
• Learning curve during implementation – Some users mention a moderate learning curve when first setting up custom flows or integrating advanced features; initial configuration may require extra support sessions.
• Higher cost compared to simpler alternatives – A few businesses note that while value is high, pricing may be out of reach for smaller organizations seeking only basic automation capabilities.

Online customer reviews: Calldesk AI vs Poly AI

Calldesk AI vs Poly AI: Online Reviews Comparison

Looking at the online reviews for both Calldesk AI and Poly AI reveals interesting insights about how users perceive these AI voice assistant platforms. Here's what I found about both products from various review platforms.

Calldesk AI

Calldesk AI specializes in automating repetitive customer service calls with AI voice agents, helping businesses enhance productivity and customer satisfaction while freeing up human agents for more valuable interactions. The platform offers AI IVR, AI Receptionist, and AI Answering Service capabilities. However, there are currently no online user reviews available on G2, Capterra, Product Hunt, Trustpilot, or other major platforms. Potential customers should be careful when considering this product due to the lack of verified user feedback.

What users are saying about Calldesk AI:

Unfortunately, no user reviews could be found for Calldesk AI across the major review platforms. This lack of reviews makes it difficult to assess real-world performance and customer satisfaction with the product. Businesses considering Calldesk AI should request case studies or direct references from the company before making a decision.

Poly AI

Poly AI offers AI-powered voice assistants for automating client calls with natural-sounding voices. The platform has received positive feedback for its conversational capabilities and integration options. Poly AI has received numerous reviews across platforms, with particularly strong ratings on G2, where users praise its natural conversation abilities and customer support.

What users are saying about Poly AI:

"Exceptional capability to automate client calls" - Anonymous User. "I loved Poly AI for its exceptional capability to automate client calls. Their customer support is commendable. The interface is simple and very user friendly. We have been able to integrate it with various software systems. Provides human like voice that is of the highest quality imaginable..."

"Only downside is the public's acceptance" - Anonymous User. "Only downside is the public's acceptance of a voice assistant doing the job. Those not familiar with dealing with 'AI' tend to think of the assistant as rude although all it does is follow the script and adjust..."

Comparison Summary

When comparing these two AI voice assistant platforms:

• Poly AI has established a presence on review platforms with users highlighting its natural-sounding voice capabilities and excellent customer support.
• Calldesk AI lacks verified user reviews on major platforms, making it difficult to assess real-world performance and customer satisfaction.

For businesses looking for an AI voice assistant with proven user satisfaction, Poly AI appears to have more documented success based on available reviews. However, Calldesk AI may still be worth considering if its specific features align with your business needs, though you should request direct references or case studies before proceeding.

What users are saying about Ringly.io:

Ringly.io is known for its simplicity, and a focus on e-commerce, with features like abandoned cart recovery and order status lookups. It has a 4.8 star rating from 12 reviews on Product Hunt and other platforms.

"it stands out significantly ahead" - Bertrand, Director. We are at the initial stage of testing and have made only a few calls so far. Consequently, I have rated the product with four stars for now. However, I must express that the product has shown significant promise. When compared to competitors, it stands out significantly ahead.

"This is such a great product" - Jim Miranda, Founder. This is such a great product. I have been with you for less than a week and already closed 3 deals with it."

"It really sounds like a human" - Laix, Founder. Tried Ringly.io today and the quality of the phone calls surprises me! It really sounds like a human, and it reacts really fast. Will need to deploy it in action to see the full capabilities.

"How to automate customer service? -> Ringly.io" - Sidra Husnain, Founder.
