AI vs. Rule-Based Chatbots: An Overview

The ever-growing impact and market prevalence of chatbots in the business landscape cannot be denied. AI assistants play a pivotal role in assisting customers and empowering customer service specialists across a myriad of industries.

Adopting chatbots presents a significant advantage, enabling cost savings of up to 30%. While this statistic alone can sway traditionalists into becoming enthusiasts, a singular high percentage embedded in a vague promise of profit may not suffice to convince every stakeholder, nor should it. For business owners contemplating a transformation in their core department’s daily operations, it’s not a hasty decision. Numerous technical and business questions require clear answers, including the choice between a conversational AI bot or a rule-based chatbot. Let’s delve deeper.

In a simplified sense, the primary distinction between conversational AI and rule-based chatbots lies in their ability to emulate human conversation. Conversations with AI chatbots feel more natural and fluid, whereas rule-based chatbots may come across as robotic or even unintelligent. Linguists may argue that the distinction oversimplifies, as rules govern not only chatbots but also natural human conversations. Nevertheless, when it comes to conversational bots, the nuances are more apparent.

Conversational AI bots leverage artificial intelligence, machine learning, and natural language processing to be more accurate, intelligent, and proficient in answering a wide range of questions. This heightened complexity allows them to function as genuine virtual assistants, surpassing the capabilities of their rule-based counterparts in almost every aspect, though not without certain drawbacks, as we’ll explore later.

On the other hand, rule-based chatbots operate based on scripted conversation models. Their capabilities in understanding and responding to text prompts are confined to the script’s scope, though they can be programmed to respond to specific keywords. They are quick to set up and deploy, meeting basic needs like order tracking or providing general information.

Choosing Rule-Based Chatbots for Your Business

When selecting a chatbot solution, it’s crucial to evaluate its suitability for your intended purpose. Rule-based automation, limited in its capabilities, generally thrives in smaller businesses, websites, and organizations.

Advantages of Rule-Based Chatbots

  1. Cost-Effective: Implementing a rule-based chatbot is budget-friendly, with providers like Manychat asserting that automation can significantly boost revenue generation.
  2. Ease of Implementation: Rule-based chatbots, operating as flowcharts, don’t require language model training. They simplify the user journey, allowing clients to guide conversations by selecting specific buttons like “Pricing” or “Opening hours.” Once the ruleset is established and the bot connects clients with agents, it’s ready for use.
  3. Templates: Customizable, ready-made templates, facilitating easy adaptation for small businesses.
  4. Time Savings: While their capacity to handle customer service or e-commerce aspects is limited, rule-based chatbots still reduce the workload on human employees, enabling them to concentrate on more intricate tasks.

Disadvantages of Rule-Based Chatbots

  1. Lack of Personalization: Unlike conversational AI bots, rule-based counterparts lack the ability to “remember” users and track conversations for future reference, potentially resulting in unfavorable customer perceptions.
  2. Limited Use Cases: Rule-based chatbots cannot adapt dynamically and rely entirely on pre-programmed scripts. Users posing questions beyond this scope may hit a figurative wall, unaware of the chatbot’s limitations.
  3. Poor Fit for Larger Businesses: Due to their flowchart-like functionality, rule-based chatbots struggle with solving complex issues. Larger corporations, offering services beyond simple tasks like parcel tracking, may witness customers frequently resorting to the “transfer to agent” option, rendering their customer service bot obsolete.

Choosing AI-Powered Chatbots for Your Business

Conversational AI chatbots possess a distinct advantage over their rule-based counterparts: intelligence. Leveraging Machine Learning and Natural Language Processing, these chatbots comprehend user prompts and respond dynamically, eliminating the need for preloaded scripts. This results in more natural and fluid conversations for users, offering several advantages:

Advantages of AI-powered Chatbots

  1. Multilingual Support: Conversational AI’s capacity to respond in multiple languages, given appropriate training datasets, is a significant advantage.
  2. Advanced Customer Service: Machine learning applications elevate chatbot support to nearly human levels, enhancing the overall customer experience. Virtual assistants utilizing AI can handle complex issues, making them ideal for large organizations such as blue-chip companies.
  3. Enhanced Data Protection: Unlike rule-based chatbots often deployed on external clouds, conversational AI typically operates on internal servers or private clouds, providing additional protection against data theft—especially crucial for sectors like banking or healthcare.
  4. Consistent Responses: Entity recognition enables AI-powered chatbots to remember conversation context, retaining information about the client’s previous questions or concerns for easy reference.

Disadvantages of AI-powered Chatbots

  1. Longer Setup: Implementing conversational AI requires significantly more time compared to rule-based chat assistants. Proper setup often involves coordination among various team members, including the IT team, DevOps, and testers.
  2. Customer Apprehension: Despite the sophistication of AI companions, some customers remain hesitant to interact with machines. While the preference for chatbots is increasing, with 62% of customers favoring them over waiting for a human, companies in the AI sector need to work on improving the image of conversational artificial intelligence.
  3. Resource Intensive: Achieving a human-like chatbot experience and fully utilizing NLP demands substantial resources to train the AI to respond to diverse situations. This results in increased upfront costs before the chatbot can effectively assist customers.

Use Cases for AI-powered and Rule-Based Chatbots

The optimal choice of automation for a business hinges on various factors. For larger enterprises, particularly in sectors like healthcare, conversational AI proves advantageous due to its heightened sophistication. For instance, healthcare organizations might prefer conversational AI when aiming to streamline processes such as patient registration, appointment booking, or creating a medical virtual assistant for symptom checking.

Conversely, rule-based chatbots are well-suited for providing basic support to smaller enterprises. When appropriately programmed, these chatbots can handle frequently asked questions, track orders, provide updates, and execute routine tasks, thus freeing up valuable time for human agents. This is exemplified by solutions like Tidio, which, with its lower overheads and customizable templates, automates a significant portion of customer inquiries.


It’s essential to recognize that, irrespective of their technological foundation, no chatbot can universally serve as the definitive solution for every business. Before making a decision, careful consideration of the aforementioned pros and cons in alignment with your business and customer needs, as well as your specific goals, is crucial. By weighing these factors against the implementation and maintenance costs of the chatbot, you can arrive at a well-informed choice that aligns with your unique requirements.
