Understanding AI customer service chatbots: The new business imperative you need to know

Have you interacted with a fun yet helpful customer service chatbot lately?

If you’ve visited a large brand’s website, chances are you’ve seen a customer support chatbot. You may have interacted with AI customer service chatbots to get an answer to a question, to take an action (such as viewing your order history), or just out of curiosity!

In this blog, we’ll tell you everything you need to know about AI customer service chatbots! We’ll delve into how customer service chatbots are shaping the future of customer interactions, examples of well-executed customer service chatbots, best practices for designing and implementing AI customer service chatbots, and case studies of companies that have found success using AI chatbots.

First, let's define AI customer service chatbots!

What is an AI customer service chatbot?

An AI customer service chatbot is software powered by artificial intelligence (AI) that lives on a business’s website or app and can answer consumer questions digitally. By simulating human conversation in a digital chat experience, customer service chatbots help businesses automate and improve customer interactions and provide more efficient AI customer support.

Think of Apple’s Siri, but branded and embedded into your favorite brand’s app or website. Most customer service AI chatbots aren’t quite as sophisticated as Siri (yet), but the concept is similar.

It’s important to note that today’s AI chatbots are not the same as the scripted chatbots of years past. With the introduction of AI into chatbot technology, the experience has vastly improved from early chatbot software limited to pre-written scripts.

Today’s AI customer service chatbots use advanced technologies like natural language processing (NLP) and machine learning (ML) to understand, predict, and respond to customer inquiries in a way that’s both human-like and extremely efficient. This integration of AI allows chatbots to handle a wide range of customer service tasks, from answering frequently asked questions to providing personalized product recommendations and processing returns.

One of the major benefits of customer service AI chatbots is their real-time availability. Where human support agents are limited to certain working hours, AI customer support chatbots can provide round-the-clock service. Serving up immediate responses to customer inquiries at all hours of the day and night is a win both for businesses and their customers. With 74% of customers willing to speak with a bot to get an answer to a simple question and 90% of people wanting businesses to use chatbots, consumers are primed to engage with chatbots. Moreover, businesses that use chatbots see a nearly 70% increase in sales, and industries such as e-commerce see a whopping 70% increase in conversions with sales chatbots!

Efficiency is also a huge benefit. Since AI chatbots can handle many queries simultaneously, this can dramatically reduce wait times and free up human customer service agents to deal with more complex issues. It’s no wonder that so many businesses that add chatbots experience a positive impact on their bottom line: nearly 60% of companies report a significant return on investment (ROI) from using chatbots.

With more customers requiring customer support online, understanding and effectively implementing an AI customer service chatbot is a crucial strategy for satisfying this growing demand. As customer service chatbot technology continues to improve, becomes more accessible, and transitions to easier implementation, the shift to integrate AI into customer support is only poised to grow.

Generative AI powered chatbots: Revolutionizing customer service

Chatbots have been around for a long time, with the widely recognized first chatbot, Eliza, created in 1966 by MIT computer scientist Joseph Weizenbaum. Chatbot technology has been characterized by a series of advancements and lulls, and several decades passed until the technology emerged on the consumer market after the introduction of the internet as we know it today. Conversational or AI-powered chatbots use NLP and ML to learn and improve over time. This technology came onto the scene in 2010 with IBM’s Watson system. The 2010s also saw the introduction of both Apple’s Siri and Amazon’s Alexa.

But what we’re most interested in here is the introduction of generative AI chatbots, which was kicked off with Jasper AI’s emergence in 2021. Since then, chatbots like ChatGPT and Bard, which are trained on massive data sets and are far more advanced and “intelligent” than previous bots, have quickly advanced the capabilities and applications of this technology. (Check out TechTarget’s full timeline of the evolution of chatbots.) This AI chatbot technology can be applied to fulfill a range of customer service (and many other) tasks for businesses.

The current AI chatbot technology has undoubtedly transformed the way businesses interact with their customers, offering more personalized, efficient, and intelligent solutions.

Let’s think back a decade. Businesses that used early chatbots relied on basic, rule-based technology. These early chatbots followed predefined rules and scripts to respond to customer queries. They could only answer questions they had been scripted to answer and could not converse in a more natural, human-like way. They were only helpful in a limited capacity and could not assist with more complex questions or inquiries.

Many of these limitations have been eliminated with the introduction of AI-powered chatbots. Unlike their rule-based predecessors, these chatbots use ML and NLP to learn from interactions, adapt over time, and handle a broader range of inquiries. Because of their advanced training, AI chatbots can respond in a more nuanced manner with better awareness of the context of the conversation — very similar to how humans interact.

AI chatbots can be broadly categorized into three types:

  • Rule-based chatbots: These are the simplest chatbots, programmed to respond to specific commands or keywords. They’re reliable for straightforward tasks but lack the flexibility to understand variations in language or handle unexpected queries.

  • AI-powered chatbots: These chatbots are a leap forward. AI-powered chatbots use AI to understand language and context to engage in more natural, conversational interactions. They can learn from past interactions and improve their responses over time.

  • Generative AI chatbots: These chatbots represent the cutting edge of chatbot technology. Because of their training on massive data sets and quickly advancing ML and NLP technology, they generate their replies and offer a level of personalization and flexibility that was previously unimaginable. This chatbot can engage in complex conversations, continuously learning and evolving its understanding of language and context.

The rise of AI in customer service through AI-powered and generative AI chatbots marks a significant shift from transactional customer service chat interactions to more engaging, conversational experiences. Today’s AI chatbots don’t just respond to customer needs; they anticipate them, leading to more satisfying and effective customer interactions. Let’s explore some key benefits of using AI chatbots for customer service.

Top 10 advantages of AI customer service chatbots: Here's why you need them

AI chatbots have notably transformed customer service, offering a range of benefits that enhance both customer experience and improve operational efficiency:

  1. 24/7 availability - AI chatbots are available around the clock so customers can get assistance anytime, helping improve overall customer service satisfaction.

  2. Handling large volumes of queries: AI customer service chatbots can manage numerous conversations simultaneously, significantly reducing customer wait times and improving efficiency.

  3. Personalization: By analyzing customer data, AI chatbots can deliver personalized experiences, making suggestions tailored to individual preferences and past interactions.

  4. Cost efficiency: Implementing AI chatbots is an effective way to augment your support staff while limiting the hiring of human agents, though human customer support agents will always be necessary to oversee chatbots, handle complex queries, and offer the crucial element of empathy in customer interactions.

  5. Consistent responses: AI customer service chatbots offer consistency in responses, ensuring that the information provided to customers is accurate and uniform, avoiding inconsistencies or errors from miscommunication.

  6. Improved customer engagement: With conversational AI, chatbots can engage customers in a more human-like manner, helping enhance the interaction quality efficiently (still, AI chatbots are not perfect and require human oversight).

  7. Instant response: Speed is crucial in customer service. AI chatbots provide immediate responses to queries, helping brands significantly improve response times and freeing human customer service agents to deal with complex inquiries and situations requiring a human touch. This also increases CSAT.

  8. Reduced human error: AI chatbots help reduce human error in customer service interactions. AI customer service chatbots mitigate damage from the inconsistent presentation of information, helping support accurate information delivery (though chatbots may present inaccuracies and require human supervision).

  9. Scalability: Customer service AI chatbots can easily scale up or down based on demand. AI chatbots for customer service offer more flexibility during peak periods or promotional campaigns, helping supplement your human staff.

  10. Analytics and insights - AI customer service chatbots can gather and analyze large volumes of data from customer interactions, providing valuable insights into customer needs and preferences. Brands can use this data to improve service delivery.

Integrating AI customer service chatbots can enhance the entire customer experience when implemented effectively.

10 guidelines on how to craft an exceptional AI customer service chatbot

AI chatbot

It’s no easy feat to design a chatbot that delivers an exceptional customer experience. Many businesses set out to develop a custom AI customer service chatbot internally, only to run into barriers with in-house resourcing, ongoing maintenance, and the continual upgrades required to keep up with developments in the industry. This is why companies often partner with a customer service chatbot provider, like Sendbird, specializing in this technology.

The goal is to create a chatbot that understands and responds to user needs and engages customers in a way that feels natural and helpful — upholding your brand standards while making your customers feel valued. Here are some guidelines to keep in mind to craft chatbots that excel in customer interactions:

Focus on Natural Language Processing (NLP)

The foundation of any effective AI customer service chatbot is its ability to understand and process human language. Robust NLP capabilities allow the AI chatbot to comprehend nuances, slang, and even typos in customer communication, helping keep interactions as smooth and natural as a conversation with a human agent. With advanced NLP, for example, an AI chatbot would likely be able to identify a similarity between the questions, “How do I change my billing address?” and “Where do I change my billing address?” and provide relevant information for both questions.

Ensure user-friendly chatbot design

The chatbot interface should be intuitive and straightforward. Aim for a clean, simple chatbot design, with easy-to-navigate menus and clear prompts. Remember, not all users are tech-savvy, so make the chatbot easy to use for everyone by mimicking a familiar chat experience like SMS or social media chat. This involves creating not just a streamlined chatbot UI, but also a user-friendly experience as described.

Personalize the chatbot interaction

Train your bot to tailor conversations based on the customer’s previous interactions, preferences, and purchase history.

Implement continuous learning and adaptation

A well-developed chatbot learns from each interaction. Conversational AI for customer service should draw on machine learning algorithms and can evolve and improve over time, adapting to customer feedback and changing behaviors.

Ensure seamless escalation to human customer support agents

Despite advances in conversational AI, situations will always require human intervention. Your chatbot should be able to seamlessly escalate complex or sensitive issues to human agents to avoid frustrated customers.

Feedback mechanism for improvement

Incorporate a feedback system where customers can rate their chatbot interactions and regularly update and refine the chatbot based on this feedback. If you deploy your chatbot on an app, consider sending an in-app notification to ask for feedback or programming the AI chatbot to ask customers directly.

Cultural and linguistic adaptability

If your business serves a diverse customer base, ensure your chatbot can handle multiple languages and cultural nuances, ensuring inclusivity and accessibility. Remember that poorly translated bot interactions can be hilarious at best and seriously damage your brand reputation at worst.

Proactive AI chatbot engagement

Instead of being purely reactive, a well-designed chatbot should also have the capability to initiate conversations, such as for offering assistance or recommendations, based on certain triggers or customer behaviors, at just the right moment.

Transparency and customer trust

Be clear with users that they’re interacting with a chatbot and give them easy access to terms. Demonstrating that the AI customer service chatbot adheres to privacy standards and data protection regulations is crucial for maintaining customer trust.

Integration with your technology stack

A chatbot should not exist in isolation. Integrating a chatbot with your CRM, sales, and marketing systems can provide a more holistic view of the customer and help inform larger business decisions.

By focusing on these key aspects, your business can design a chatbot customer experience that meets the functional requirements and enhances the overall customer experience.

But what does a well-implemented customer service chatbot look like? Let’s explore some examples.

4 quick tips on how to implement your own AI customer service chatbot

Introducing AI customer service chatbots requires careful planning and execution to be truly effective. Here are some tips to help with a smooth and successful implementation:

Integrate your customer service AI chatbot with existing channels

Make sure to integrate your chatbot software with your existing customer service channels. The chatbot should complement and enhance your current support system, not operate in isolation. This integration ensures a cohesive experience for customers, whether they interact with a human agent or a chatbot.

Familiarize staff with the AI chatbot

It’s equally important to train your staff to work alongside your customer service AI chatbot. Employees should understand how the chatbot operates, the types of queries it can handle, and when to take over from the chatbot. Build in clear rules for how to monitor and supervise the chatbot for customer service, as it should not operate without human oversight.

Set clear objectives and expectations for customer service AI

Define what you want to achieve with your customer service AI chatbot. What are your major goals and KPIs? For example, do you aim to reduce response times, handle common queries, or provide 24/7 support, or more? Align clear objectives with key performance indicators (KPIs) for gauging success, which will help guide the AI chatbot implementation process.

Focus on continuous AI chatbot improvement

A customer service chatbot isn’t a set-it-and-forget-it tool. Regularly analyze chatbot interactions to identify areas for improvement. Review customer feedback and chatbot performance data frequently to refine and update the chatbot’s responses and capabilities.

Remember, a chatbot is part of a larger customer service strategy, and its success should be measured by how well it enhances the overall customer experience.

Enhancing customer service AI chatbot efficiency through analytics

Upholding an optimal chatbot customer experience involves analyzing chatbot interactions and making data-driven improvements. Start by choosing which main metrics to track.

4 key customer service AI chatbot customer experience metrics to track

  1. User satisfaction rate: A straightforward indicator of how well the customer service AI chatbot meets customer needs, this metric is gathered through direct feedback from users after their interaction with the chatbot. A high satisfaction rate means your chatbot is on the right track, while a lower rate signals a need for adjustments.

  2. Resolution rate: This measures the percentage of queries resolved by the chatbot without escalating to a human agent. The higher the resolution rate, the more effective your chatbot is at handling customer inquiries independently.

  3. Conversation abandonment rate: How often users disengage or drop out of conversations with the chatbot. A high abandonment rate could indicate confusion, frustration, or dissatisfaction with the chatbot’s responses.

  4. Response time: The AI chatbot response time measures how long it takes for the chatbot to respond to user queries. Aim for fast response times to help ensure a positive user experience. Of course, the response time should be balanced with the quality and relevance of the response.

Remember that the most important thing about metrics is how you act on the insights they provide. Follow these 5 steps to fully leverage your data:

  1. Identify patterns: Look for common trends or issues in interactions with the AI customer service bot. Are there specific points where users tend to drop off? Do certain questions lead to lower satisfaction rates? Adjust accordingly.

  2. Gather user feedback: Your software should have a simple way to gather direct user feedback, providing insights into issues that metrics alone might not reveal.

  3. Continuously test and optimize: Use A/B testing to try different approaches in the chatbot’s conversation flows. Analyze how these changes impact your key metrics and user satisfaction.

  4. Update content regularly: Keep the chatbot’s content up-to-date and relevant. This includes not only the information it provides, but also the style and tone of its communication.

  5. Train the AI: Use the data to train the chatbot’s AI engine, especially if it's built on machine learning algorithms. The more data it has, the better it can learn and adapt to user needs.

By regularly analyzing these metrics and making informed improvements, you can significantly enhance the performance and user satisfaction of your conversational AI for customer service.

Real-world success stories of customer service AI: How AI chatbots transform the customer experience

Customer service AI is transforming customer support across various industries. Let’s dive into two case studies of Sendbird customers that have found success with customer service chatbots.


Upwage case study

Upwage, a job posting platform, needed to make the recruitment process more efficient, particularly for screening hourly workers. The major hurdle was the enormous amount of time it took for staff to screen numerous applications and conduct initial candidate assessments.

To address this challenge, Upwage partnered with Sendbird to integrate AI-powered chatbots into their platform with SmartAssistant. With the included integration to OpenAI's LLM used by ChatGPT, Upwage developed a responsive and scalable chatbot system that automated the initial screening of job applicants, significantly accelerating the hiring process.

This partnership has greatly improved the team’s applicant screening process, leading to substantial time savings, improved efficiency, and positive user experiences. Upwage was able to save 50% of recruiters’ time for more nuanced work, and achieved 3x concurrent applicant screening sessions.

As COO and Co-founder Greg Call explains, “Our success is measured by the hours saved for recruiters who no longer need to conduct screenings at scale manually. Some recruiters were spending four to eight hours on screenings daily. Now, Upwage AI Screener automates these screenings, enabling them to focus on more value-added tasks.” Read Upwage’s full story.


AllAthlete case study

AllAthlete, a sports recruitment app, struggled to facilitate effective communication between athletes, recruiters, and coaches. The app’s mission to democratize athletic recruitment relied heavily on maintaining active user engagement and efficient communication, but their initial AI chat solution wasn’t up to par — the chat solution was deleting chats and changing users’ profile names without anyone knowing it.

To overcome these challenges, AllAthlete turned to Sendbird to build custom ChatGPT chatbots for a more reliable and user-friendly experience. With three different bots designed to guide users on platform usage, assist in athletic development, and bridge communication gaps between athletes and coaches, the technology has added a consistent, personal touch to the user experience.

With Sendbird, AllAthlete saw a 25% increase in user retention and saved 100+ hours with a more reliable, AI-enabled system. Founder Greg Auerbach says, “We’ve been live with Sendbird for a few months and immediately, the solution's reliability has supported more quality conversations and a more trusted relationship with athletes that you just can’t put a price tag on.” Read AllAthlete’s full story.
