What is Conversational AI?
Conversational AI refers to technologies that enable interaction between humans and machines, whereby the system can understand, process and respond appropriately to human natural language. The term Conversational AI can be described as a dialogue system based on artificial intelligence – in other words, a combination of AI and conversation. Communication takes place in the form of text or speech and in real time across various channels. Unlike early-generation rule-based chatbots, which merely process predefined response paths, conversational AI is based on developments such as
- Large Language Models (LLMs)
- Natural Language Processing (NLP) and
- machine learning (ML)
The result is systems that understand context, learn from interactions and adapt. These technologies can be deployed in many areas, including, for example, customer service and sales.
From response engine to autonomous agent
By 2026, intelligent systems will no longer act merely reactively, but proactively: they will carry out multi-stage tasks independently and will be able to access internal knowledge databases and external systems. They make context-based decisions and only hand over to a human employee when it is truly necessary. These so-called AI agents or agentic AI systems are regarded as the next stage in the evolution of technology and have now become an integral part of leading platforms. We have compiled more on this in our article …
What is the difference between conversational AI and chatbots?
Conversational AI refers to the underlying technology and the broader field, whereas the term ‘AI chatbot’ usually refers to a specific application – such as on a website or in customer service. However, the terms ‘AI chatbot’ and ‘conversational AI’ are now largely used interchangeably, and both describe AI-powered systems that understand natural language and respond contextually.
There are various types of chatbots; in terms of technology, a basic distinction is made between rule-based chatbots and intelligent chatbots. A rule-based chatbot does not operate using artificial intelligence, but rather on the basis of predefined rules. However, the use of AI in chatbots is now standard. Artificial Intelligence gives these chatbots the ability to learn from conversations, develop independently and also understand free-text inputs. The most significant current development is the transition towards agent-based chatbots based on large language models, which can act independently and perform tasks. Here is an overview of the classification of AI chatbots:
The key features of intelligent chatbots at a glance:
- Intelligence & understanding: AI chatbots can understand context, intent and sentiment using conversational AI.
- Learning ability: Conversational AI improves through continuous learning from interactions; AI chatbots can do this too, but it requires a greater amount of manual effort.
- Functionality: Simple chatbots were previously better suited to answering basic FAQs; with the help of conversational AI, complex dialogues can now be conducted and personalised responses and suggestions provided.
It is therefore not necessarily a question of ‘either/or’, but rather one of collaboration and combination. In our moinAI solution, the chatbot utilises conversational AI in the background to provide users with personalised responses.
Applications of Conversational AI
Conversational AI is particularly common customer service, but also marketing & sales can benefit from it. Many companies are already demonstrating how well it works (see our case study below). Some of the sectors using conversational AI include the following:
It is clear that conversational AI is used wherever there are high volumes of communication and where speed and personalisation are crucial to the interaction. Typical use cases include answering standard enquiries to relieve the workload on human teams, providing personalised purchasing advice, an employee self-service portal for IT enquiries, or booking appointments via AI. The great thing about conversational AI is its potential for development and its adaptability; it adapts to users and their questions and concerns. Last but not least, conversational AI grows alongside its field of application and continues to develop independently on that basis.
What Are the Benefits of Conversational AI?
Conversational AI takes the pressure off service teams by answering recurring enquiries fully automatically, 24/7, whilst scaling in line with enquiry volumes without costs rising proportionally. Customer satisfaction is measurably improved, partly due to integration with existing systems such as CRM or the knowledge base. Responses are based on real company data rather than generic text templates. Further benefits of conversational AI:
- 24/7 availability: enquiries are answered immediately, even outside of service hours
- Consistent communication: standardised, brand-compliant responses across all channels
- Shorter response times: customers receive an immediate reply, with no waiting time
- Continuous learning: the system independently identifies gaps and learns from every conversation
- Measurable results: automation rate, customer satisfaction, ticket volume; transparent and analysable
- GDPR compliance: with reputable providers such as moinAI, data protection is ensured from the outset, including AI labelling in accordance with the EU AI Act
- Cost-benefit ratio: investments usually pay for themselves quickly due to the reduced ticket volume.

Case Study: ImmoScout24 Best Practice
One example of the successful use of conversational AI is ImmoScout24, which uses moinAI’s AI chatbot on its website. The leading German property platform connects around 5.6 million people with their ideal home every month and caters to a broad ecosystem of users on both desktop and mobile. As the central point of contact for such diverse user groups, the volume of enquiries was correspondingly high. The real challenge, however, lay not in the volume, but in the lack of structure: knowledge was scattered across external FAQs, Confluence and Salesforce, with no unified foundation.
The starting point:
- Enormous volumes of enquiries without a scalable process: no 24/7 service, unable to cope with peak times
- Fragmented knowledge management without a central knowledge base
- Redundant and contradictory content led to incorrect answers
The goal: Resolving recurring customer enquiries in a single interaction. The chatbot should not only route enquiries but provide genuine answers, quickly and around the clock. For more complex issues, a seamless handover to a human agent via live chat is possible.
Areas of application:
- Login issues and account access
- Billing queries
- Navigation and orientation questions
- Application issues and functionality queries
Using a ‘learning by doing’ approach, implementation was carried out iteratively, with ImmoScout24 continuously monitoring all relevant metrics and the automation rate. The proactive identification of missing content proved to be a key success factor: The chatbot independently suggests new topics that customers raise in the chat, thereby saving a considerable amount of maintenance effort.
ImmoScout24 currently achieves an automation rate of around 75%, with the clear aim of growing to over 90%. The service remains fully scalable, regardless of how much the volume of enquiries increases.
Challenges When Using Conversational AI
Among the most common challenges when using conversational AI are fragmented knowledge bases, complex system integrations, a lack of internal maintenance processes, and issues with team acceptance. Added to this are regulatory requirements under the GDPR and the EU AI Act, as well as organisational challenges such as defining responsibilities.
Key challenges include the following aspects, amongst others:
Data protection and security: The protection of personal data is essential. Risks include data misuse and security vulnerabilities arising from overloaded server resources. moinAI is hosted in Germany and meets all GDPR requirements, allowing users to interact with the AI with peace of mind.
Conversation quality: Particularly with dialogue-oriented AI, quality depends on how well the AI system can maintain context across longer conversations. If the AI struggles with this, it can lead to repetitions or irrelevant answers.
Accuracy and hallucinations: Artificial intelligence is not perfect, and this is repeatedly demonstrated by so-called hallucinations, i.e. the AI can make false statements or invent information. This is particularly problematic in service sectors, but providers are addressing it using tests such as SimpleQA (OpenAI). We have summarised everything on the topic of hallucinations in this article.
Technical integration: Seamless integration into existing backend systems (CRM, ERP) is complex and requires the relevant expertise within the organisation.
Ethical aspects, bias and acceptance: Conversational AI also faces further criticism regarding the training data used for the models. This data can reinforce biases; active countermeasures must be taken to prevent this. The greater the users’ trust in the AI, the more useful the solution is perceived to be. This is reflected in a high usage rate.
The application of conversational AI should always be centred on the question: “How can the user best be helped?”. Companies should therefore examine real user data and queries before deciding on the thematic direction in which conversational AI should develop. It is advisable to analyse all communication channels used, such as the service hotline, emails or social media messages, in order to identify frequently raised topics via conversational AI and define clear use cases.
The leading conversational AI providers in 2026
Depending on the use case, the leading conversational AI providers include, on the one hand, platforms specialising in enterprise communication such as moinAI, Botpress and Intercom, and, on the other hand, the major LLM providers such as OpenAI, Google and Anthropic.
The conversational AI market will be highly diversified by 2026, ranging from enterprise solutions for contact centres to streamlined builder tools for SMEs. Conversational AI is often integrated as a feature into existing platforms. There is also a wide range of niche solutions specialising in individual channels such as WhatsApp or voice. For businesses, this wide choice means that a clear distinction must be made between technology building blocks and complete solutions.
We highlight some of the best-known providers and provide an overview:
Conversational AI can effectively complement human work in the service sector, but it can never completely replace it. Nevertheless, the introduction of conversational AI may give rise to concerns and reservations among some people. It is important to take these concerns seriously and address them through education and information resources. We explore the topic of ethics and AI in more detail in our article “Ethical AI - Responsible Automation in Customer Communication”. Even though conversational AI can take on many (particularly repetitive) tasks, it will not be able to replace human interaction, humour or emotional intelligence. When introducing conversational AI, teams and staff should therefore ideally work hand in hand to get the most out of this innovative technology.
Conclusion: the Importance of Conversational AI for the Future of Customer Communication
Conversational AI bridges the gap between rising customer expectations and the simultaneous increase in enquiry volumes: with conversational AI, precise and personalised responses have become the norm in communication. As the variety of channels – such as email, chat, WhatsApp, voice and social media – continues to grow, conversational AI is also finding greater application within businesses and, when implemented correctly, ensures long-term customer satisfaction.
Reactive responders are increasingly being replaced by autonomous AI agents that initiate processes independently and resolve tasks from start to finish without the need for human intervention. Companies that build a solid data foundation and robust automation logic lay the groundwork for intelligent, dialogue-oriented customer service.
moinAI deploys conversational AI specifically for customer service, developed especially for SMEs in the DACH region and, as an AI solution, 100% GDPR-compliant. The AI chatbot can be integrated quickly and is designed from the outset for end-to-end automation.
