Suhas Palani - PeerSpot reviewer
Full Stack Developer at Tundra Technical Solutions
Automation has transformed tier-one support and now reduces wait times while improving handoffs
One area for improvement in Conversations by NLX would be the initial learning curve for setting up some of the more advanced integrations with our older legacy systems. We occasionally encounter small hiccups where the bot has trouble maintaining context across a very long, multi-turn conversation. Having even more robust, out-of-the-box reporting features would also be a fantastic addition for deeper analysis. More comprehensive documentation for Conversations by NLX with more detailed code examples and a more centralized developer hub would make the initial development and debugging process much smoother. The main things holding Conversations by NLX back from a higher score of 9 or 10 are the hurdles we faced during the initial setup with our old legacy systems and the need for more in-depth documentation to support developers. Those context gaps during longer conversations also mean it is not quite at a perfect level yet.
Harman Singh - PeerSpot reviewer
Devops Manager at Microsoft Ai
Automation has reduced routine inquiries while agents have gained time for complex issues
The best features PolyAI offers include its professional service as a software approach, which is a significant differentiator during initial onboarding, with the structured questionnaire process capturing our architecture, security constraints, brand voice, and API handshakes down the wire. They work instead of handling a raw, self-serve bot builder, allowing our platform engineers to avoid constant babysitting while PolyAI's dialogue engineers handle model fine-tuning, edge case routing, and continuous optimization. I also appreciate the low-latency, human-parity voice system, which helps the voice agent handle non-linear speech, sudden conversational pivots, background noise, and mid-sentence interruptions naturally, making audio latency practically imperceptible and eliminating the awkward pauses typical to traditional conversational IVRs. This is a game-changer. Finally, I appreciate how moving between chats and voice maintains context seamlessly, as conversations trigger or fallback or human handoff. State payloads transfer cleanly with zero loss of session context. The low-latency and human-parity voice system make a significant difference for our team, ensuring that interactions between AI and humans do not sound robotic. This capability makes the AI's responses clear, without context lagging or hallucination. Our end user experience has positively increased by 23.5%. Earlier, latency posed a challenge, but low latency ensures that we can achieve our end goals efficiently. The governance and security of PolyAI is really strong. It has not missed anything in terms of governance and AI, which I feel has been handled really well. The accuracy and reliability of PolyAI's AI output is exceptional, more than 200%, since it does not hallucinate, provides long answers without losing context, and utilizes low latency and advanced AI models. They have done a good job in this aspect.

Pros

"The best features Conversations by NLX offers include flexibility and the ability to loop back to the main question."
"We deployed Conversations by NLX with a localized automated flow in Traditional Chinese that handled 65% of incoming tier-one inquiries right out of the gate, verified customer IDs, and pulled real-time tracking data from our logistics backend, which significantly reduced wait times and relieved pressure on our support team."
"Conversations by NLX has positively impacted my organization by increasing user engagement by thirty percent."
"What I appreciate most about the multilingual support is that while I think the accuracy is good, I am more inspired by the range of languages, and I feel it's quite deep, getting the context correctly."
"We developed more than fifty chatbots using Conversations by NLX, which provides mostly friendly and very easy to implement functionality."
"My customers are responding very positively toward the features of Conversations by NLX, as it is a state-of-the-art tool with features that no other competitor has and definitely something that leaves them impressed after viewing the demos."
"In my opinion, the best feature Conversations by NLX offers is natural language processing, because whatever language you are using, whether it is Hindi, English, or any other language, it will convert it accurately, letting you feel as though you are talking to a human."
"What I like the most about Conversations by NLX is that the contact center industry, especially the legacy contact center industry, is very much accustomed to and comfortable using drag-and-drop blocks, connecting them, and writing the required business or application logic to serve business requirements."
"The low-latency and human-parity voice system make a significant difference for our team, ensuring that interactions between AI and humans do not sound robotic."
"Overall, PolyAI has been a great addition to my customer service workflow, and its strong natural language understanding, voice quality, and automation have helped improve efficiency."
 

Cons

"Conversations by NLX could improve on some advanced use cases, as they might need help with the technical setup and integration."
"From my perspective, it would be helpful if you could integrate Conversations by NLX with multiple channels to create a more friendly and reachable product."
"If someone is in a conversation and things are added when it came to the customer support journey, the discussions can become lengthy, and it loses the context of understanding, maybe asking for repetition of things."
"In my experience, Conversations by NLX is not stable, and I have not used it."
"I think improvements are needed for Conversations by NLX through the learning platform, even small ones."
"We occasionally encounter small hiccups where the bot has trouble maintaining context across a very long, multi-turn conversation."
"I was not able to get approval to implement Conversations by NLX to more customers and business units because the cost is still high, especially when LLMs or AI get involved."
"The possibility to have Conversations by NLX on-premises would be beneficial because I have not seen that Conversations by NLX is providing an on-premises solution."
"One area where PolyAI can be improved is in deeper integrations with existing systems and more configuration on how to handle complex scenarios."
