AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
You pay based on usage, not fixed licenses. A monthly subscription fee covers platform access. Conversations are billed by type: chat, voice, and multimodal. Some dimensions price each conversation type separately, while others combine chat, voice, and multimodal into a single conversation charge. An overage dimension applies extra fees when combined conversation volume exceeds your included amount. A separate Agentic Execution dimension charges for automated actions the platform runs on your behalf. Your total scales with how many conversations and executions you use each month.
Top-of-mind questions for buyers
What counts as one conversation for billing, and does channel type change how it counts?
A conversation is a single session between a user and the AI. Chat, voice, and multimodal each count as one conversation per session. Some dimensions price these channels separately, while the combined Conversation dimension counts any channel type as one unit.
What happens to my bill when combined conversation volume goes past my included amount?
Once your combined chat, voice, and multimodal conversations exceed the included amount, the Conversation (Overage) rate applies to the extra conversations. Only conversations beyond your included volume are charged the overage rate. Conversations within your included amount stay at the standard rate.
How do the monthly subscription, conversation, and Agentic Execution charges combine on one bill?
The monthly subscription is a fixed fee for platform access. Conversation charges add per session by channel. Agentic Execution charges add separately for automated actions the platform runs. All charges apply together and scale with your usage each month.

Voice and chat automation has transformed how I manage appointments and patient support
Reviewed on Aug 19, 2026
Review provided by PeerSpot
What is our primary use case?
My main use cases for Conversations by NLX involve customer support and patient services, including rescheduling, booking appointments, and cancelling.
For customer support and patient services with Conversations by NLX, I manage appointment details by rescheduling and cancelling, ensuring we have enough intent, fetching the data using entities, and implementing FAQ automation by adding patient-related questions. Calendar integration enables users to easily reschedule, cancel their appointments, and book new ones.
Regarding my use cases, we are implementing NLU (natural language understanding) to fetch user intention, and we provide human-like behavior with voice chat, making the interaction more similar to speaking with a human.
What is most valuable?
The best features Conversations by NLX offers include multimodal capabilities and FAQ automation.
The multimodal feature is crucial. While it can be challenging to maintain chat along with omni-channel chat and voice, using Conversations by NLX makes it easy to combine voice, chat, and omni-channel support through web chat and telephony IVR.
I have recently noticed that the Gen A feature is very impressive, using RAG to provide proper answers and fetching accurate content, resulting in less hallucination during the training of FAQs.
Conversations by NLX has positively impacted my organization by increasing user engagement by thirty percent. We transitioned from the Microsoft bot framework to the NLX framework over the past year, which has resulted in higher user engagement and improved user solutions for appointment rescheduling and cancellations from the bot itself.
What needs improvement?
I believe that Conversations by NLX could benefit from reducing hallucination by expanding training intents and adding more integration possibilities with CRM ticket systems and other platforms.
I must emphasize the need for more training systems and integration with other platforms such as SRE, CRM systems, ticket systems, and APIs to enhance the functionality of Conversations by NLX and reduce hallucination.
For how long have I used the solution?
I have been using Conversations by NLX for around one year.
What do I think about the stability of the solution?
Conversations by NLX is stable.
How are customer service and support?
The customer support of Conversations by NLX is excellent.
I rate customer support for Conversations by NLX as a ten.
Which solution did I use previously and why did I switch?
Previously, I used the Microsoft bot framework and decided to switch because their desktop support became unavailable when they moved to Copilot.
What was our ROI?
We have seen a return on investment as we have saved money. Conversations by NLX does not require deep technical knowledge, allowing all employees to use it effectively, making it user-friendly.
We measure the increase in user engagement through analytics, which has allowed us to quantify the improvements.
What's my experience with pricing, setup cost, and licensing?
I do not have much experience regarding pricing, setup cost, and licensing as those aspects were handled by the company. I primarily focus on development and analytics.
Which other solutions did I evaluate?
Before choosing Conversations by NLX, I evaluated various options including Microsoft bot framework, Google Dialogflow CX, Amazon Lex, and IBM Watson.
What other advice do I have?
On a scale of one to ten, I would rate Conversations by NLX as a ten.
I chose ten because it has unique features that are not yet popular in the market. It offers more functionalities with less hallucination and is very user-friendly.
Conversations by NLX has eighty to ninety percent accuracy and reliability, along with scalability in a similar range.
I advise others looking into using Conversations by NLX that it may not be popular or well-known in the market, but it offers more features at a lower price compared to others such as OpenAI.
My overall review rating for Conversations by NLX is ten out of ten.

Omnichannel virtual assistance has improved support efficiency but still needs better context handling
Reviewed on Aug 02, 2026
Review from a verified AWS customer
What is our primary use case?
I have been exploring Conversations by NLX in a couple of my projects around three to four months back. My exploration was conversational and analytical to improve our customer's projects. Basically, I use Conversations by NLX for omnichannel support and integration with our team's systems.
What is most valuable?
Conversations by NLX offers a visual conversation builder that is intuitive and allows both technical and non-technical users to collaborate with end-to-end recognition and conversation flow management of design, making customer interactions feel more natural.
Conversations by NLX is easy to integrate with back-end services, APIs, and authentication, so integration flexibility stands out to me.
The architectures of Conversations by NLX appear suitable for organizations handling high interaction volumes.
I see that Conversations by NLX provides analytics and continuous improvements, which are valuable.
Conversations by NLX functions as a virtual assistant across customer support channels. Customers come through different inquiries and integrate with diagnostic data at runtime, which helps address their needs.
Conversations by NLX is replacing our chatbot and agents that we were using with in-person customer representatives.
What needs improvement?
I think context-wise, if Conversations by NLX could improve to maintain consistent context, that would be beneficial.
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. This is one concern with Conversations by NLX.
Another concern is the volume of data. In customer support when dealing with enterprise customers, for example, if an organization has 50,000 employees requiring support for their hardware from different vendors, there is massive data coming in. The response time in terms of calculating and querying could be improved. If the efficiency can increase, that would be helpful.
Because Conversations by NLX is mostly covering standard cases and some edge cases, there are many competitors in the market available now. I would check the quality of the response, the response time in terms of scalability, and different contexts. These are areas where improvement would be beneficial.
For how long have I used the solution?
I have been working in my current field for the past 20 years.
What do I think about the stability of the solution?
Conversations by NLX is stable in my experience, though there is sometimes downtime or issues.
What do I think about the scalability of the solution?
Conversations by NLX sometimes faces difficulties regarding scalability, though sometimes it performs fine.
How are customer service and support?
I am satisfied with the customer support for Conversations by NLX. I would rate the customer support for Conversations by NLX an eight on a scale of one to ten.
Which solution did I use previously and why did I switch?
I explored many systems before Conversations by NLX, including Sierra, Zoom, and others in the marketplace. It was an exploration journey where I checked which system is the best.
Before choosing Conversations by NLX, I worked with Sierra, Zoom, and OpenAI.
How was the initial setup?
My experience with pricing, setup cost, and licensing for Conversations by NLX seems fine.
What was our ROI?
Conversations by NLX is worthwhile. It is money-saving and time-saving as well.
Which other solutions did I evaluate?
I am not interested in being a reference for this vendor.
There is a market that is diverging, and every day new things are coming. OpenAI is on its way, and there are many big players in the market right now. The efficiency, accuracy, and response time all matter for Conversations by NLX. The things which I mentioned are relevant as per the latest trends and new market competitors coming, and it would be appreciated if Conversations by NLX could follow or exceed the trending values and metrics.
What other advice do I have?
Regarding Conversations by NLX's governance and security, I have implemented a security perspective to secure our own data.
Accuracy-wise with Conversations by NLX, it is around 88% to 92%. I cannot give a fixed number, but it varies. Sometimes it is correct, and sometimes it is not exact to what I am looking for, but overall it is fine.
They mentioned that there is some incentive regarding Conversations by NLX, but I do not know what I will get or not.
I would appreciate more information on rollback management or rollback handling and which particular LLMs are supported for that feature.
My overall review rating for Conversations by NLX is seven.

Multimodal AI has streamlined multilingual red teaming and has improved guided voice journeys
Reviewed on Jul 28, 2026
Review provided by PeerSpot
What is our primary use case?
My main use case for Conversations by NLX is for multimodality experiences such as chat, voice, and text, as well as enterprise use cases with low code or some integrations, with different multilingual support. My role has a lot to do with testing different languages, so multilingual support is something I'm looking for.
I can give a specific example of how I used Conversations by NLX in one of my projects, where I'm particularly looking for differences between sarcasm, humor, and satire, and how it would respond to different things in different languages, as well as in different categories such as violent crimes and non-violent crimes. When we're doing adversarial or safety testing to check how strong the AI is, that's part of the red teaming effort that we are doing. We try different techniques, including different prompts which could trick the AI. The multilingual analysis of the prompt outputs in various categories is a critical aspect.
What is most valuable?
The best features that Conversations by NLX offers are voice and the multimodality experiences, especially for guided customer journeys across voice and digital channels.
Guided customer journeys across voice and digital channels are valuable for my team because we are a team of red teamers who do adversarial testing, and it really matters how it gives its output across different cultures, different languages, and different countries. It really has to stand out how the tools handle one channel well or if they're doing a great job connecting the experiences across different channels in one flow. Conversations by NLX positions voice to reduce friction and make the interaction feel much more seamless, especially for customers who really need step-by-step help.
Conversations by NLX has impacted my organization positively as a real differentiator for us because we do side-by-side testing for many AI models, and the multimodality experience in Conversations by NLX allows the customer to interact in more than one way during the same task, such as speaking while also seeing the prompts, choices, and confirmations. That has made a huge impact.
What needs improvement?
Conversations by NLX could improve on some advanced use cases, as they might need help with the technical setup and integration. That could be one downside, and sometimes it feels more enterprise-focused than a very beginner-friendly or lightweight tool. Some work in that area could be beneficial.
The pricing and implementation details of Conversations by NLX are not fully transparent upfront, so evaluation may require a sales conversation.
For how long have I used the solution?
I have been using Conversations by NLX for almost a year.
What do I think about the stability of the solution?
Conversations by NLX is stable.
What do I think about the scalability of the solution?
Conversations by NLX's scalability is pretty good, and they are very scalable.
How are customer service and support?
Customer support for Conversations by NLX is good. Scalability is one of the main strengths, and if I've ever needed customer support, I've had a lot of support with customer interactions. I would rate the customer support for Conversations by NLX on a scale of one to ten as a ten.
Which solution did I use previously and why did I switch?
I did previously use a different solution; however, this information is discreet, and I cannot share that. We did use a different solution at Google.
How was the initial setup?
My experience with Conversations by NLX regarding pricing, setup cost, and licensing is that I'm not the one who is mainly in charge, but the pricing and implementation details were not very fully transparent upfront.
What about the implementation team?
My company does not have a business relationship with Conversations by NLX other than being a customer; there is no relationship.
What was our ROI?
I have seen a return on investment with Conversations by NLX. We definitely saved money and time, but there were no staff that had to be let go because of Conversations by NLX. However, we could handle more projects because of it, so efficiency and time definitely improved.
What's my experience with pricing, setup cost, and licensing?
The pricing and implementation details of Conversations by NLX are not fully transparent upfront, so evaluation may require a sales conversation.
Which other solutions did I evaluate?
Before choosing Conversations by NLX, I evaluated other options, and we evaluated many different options, even including Perplexity and Copilot.
What other advice do I have?
The advice I would give to others looking into using Conversations by NLX is that they are pretty scalable, stable, accurate, relevant, and safe. I think everybody should use it.
If anybody needs a scalable, enterprise-grade conversational AI, they should go for Conversations by NLX. It looks pretty solid.
Conversations by NLX's governance and security look pretty secure, though I've never thought deeply about this parameter. It looks pretty solid on paper. They do call out the access control, the sensitive data handling, integrations, and runtime protections. For governance, I feel it's reasonably mature in the sense that the platform supports reviewability and operational oversight, but I would still want to verify practical details in the real deployment.
Regarding Conversations by NLX's AI capabilities, I feel they are accurate and reliable; almost nine out of ten times, it's accurate and pretty reliable, and the output is relevant, very consistent, and complete. I would rate this review overall as an eight out of ten.

Automating customer banking requests has improved support while AI security still needs deeper review
Reviewed on Jul 23, 2026
Review provided by PeerSpot
What is our primary use case?
Conversations by NLX is used for customers to get account details, card details, to block a card, or for loans, to get loan details, and to get a checkbook request or locate a bank branch.
We create a flow to do the task with Conversations by NLX by dragging and dropping and making a flow to accomplish this, and integrating APIs and REST APIs from the backend core banking APIs to authenticate the user or the customer. We can then proceed with the main task. For example, if a customer wants to block a debit card or wants any details, we can create a flow by creating the intents and entities. This defines what the user wants and what we are looking for. We can ask the required questions and create entities such as customer ID or registered mobile number as per the project requirements and specifics.
What is most valuable?
Conversations by NLX is user-friendly, easy to use, and environment-friendly, making it a good platform.
The drag-and-drop functionality of Conversations by NLX is easy to use. The environment is user-friendly, and we don't have to do much coding.
Conversations by NLX has helped us to assist our users and customers and develop our product for the contact center platforms.
What needs improvement?
I haven't used Conversations by NLX much, so I don't think there's an improvement needed.
Regarding Conversations by NLX's AI capabilities, the security is solid. I haven't done a deep dive into security for specific purposes, but it's secure and the authentication aspects were great.
For how long have I used the solution?
I have been working with this solution for the past four years.
How are customer service and support?
I am quite satisfied with the product we developed on Conversations by NLX.
Which other solutions did I evaluate?
We haven't had a partnership with another company. We are using a paid version.
What other advice do I have?
Conversations by NLX is quite a good platform, and that's the main reason I have chosen it. It's easy to use, user-friendly, and you don't have to struggle to work on it. My overall rating for Conversations by NLX is seven to eight out of ten.

Dynamic conversations have improved self-service options and provide human-native voice choices
Reviewed on Jul 22, 2026
Review from a verified AWS customer
What is our primary use case?
One of the reasons I explored Conversations by NLX was to investigate the platform's capabilities, as I was in a role to evaluate different platforms that provide conversational AI solutions. Conversations by NLX came into that search, and I have thoroughly explored this platform.
We were looking for a platform where we have the flexibility to choose between different models. We have different subscriptions at the company level, and we wanted to see which one would work better for us. Additionally, the flexibility to choose between different voices was important to us. We have our custom voices and corporate voices as well. These were the main things I was exploring in the first phase.
I have recently learned that Conversations by NLX is part of Amazon Connect. This was one of the reasons we considered it, because at Deutsche Telekom we were also exploring the migration from Cisco to Amazon Connect. That's the reason we got Conversations by NLX into our consideration.
We currently have a hybrid cloud setup and we have a requirement for private cloud as well, but we would like to see how Conversations by NLX could be integrated there.
What is most valuable?
Conversations by NLX offers human-native voices, a variety of models, flexibility to build, test, and deploy applications, and ease of use on the platform.
With conversational AI, we have the flexibility that we do not have to draw the IVR applications in a static way. Everything is dynamic and according to what the customer wants and asks. They can ask anything, any flow, anytime while being on the conversation.
With a Conversations by NLX solution, we can achieve more automation of different use cases. We have self-service applications which were previously limited, and now we have increased these significantly because our customers are asking for a lot more self-service features.
What needs improvement?
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. In our cases, we have some sensitive helplines where we do not want to put the data on the internet and we prefer to have everything within our network.
I think the compliance for Conversations by NLX could be checked a little more thoroughly, and the data privacy should be stronger because the European laws are much more focused towards data privacy and data residency.
For how long have I used the solution?
I have not used Conversations by NLX extensively, but I have reviewed the introductory materials. I am not an expert on Conversations by NLX, but I have gone through a couple of the documentation resources.
What do I think about the stability of the solution?
Conversations by NLX is stable from what I have seen and tested. The stability has been satisfactory, and we were able to quickly test things and evaluate Conversations by NLX platform.
What do I think about the scalability of the solution?
The scalability of Conversations by NLX is also fine. As I mentioned, we have not tested it in production, but we have evaluated it from an evaluation perspective and we were satisfied with the scalability as well.
How are customer service and support?
The customer support from Conversations by NLX was great. We had a couple of questions while setting up the environment and during onboarding. The team was very quick, and we were able to get responses within a couple of hours.
How was the initial setup?
We have not used Conversations by NLX in production. We were using it only for the test environment where we sent a couple of requests on the platform and tried to see how human-native the responses are. We were satisfied with the response, but we have not put this in production.
Which other solutions did I evaluate?
We evaluated a couple of different solutions. During the evaluations, we went through Vapi and Parloa, which is a Berlin-based company. We were also exploring different open-source solutions as well.
What other advice do I have?
Amazon Connect lives in a very big ecosystem from AWS. What they were lacking was the capability of human-native voices. I think Conversations by NLX would work for that with this partnership.
I would rate the customer support of Conversations by NLX as an eight on a scale of one to ten.
I would rate Conversations by NLX eight out of ten because of the platform flexibility, the documentation and help we receive, and the feature set.
We used to have a lot of concerns about Conversations by NLX's AI capabilities, governance, and security because we are basically European telecom providers, and we prefer to have everything GDPR compliant and are really concerned about data privacy. We reviewed the things provided by Conversations by NLX, and we were quite satisfied with that. My overall review rating for Conversations by NLX is eight out of ten.
