25 best AI chatbots of 2024

อัปเดตล่าสุด May 15, 2024

AI chatbots aren’t a luxury anymore—they’re the standard for providing an exceptional customer experience. According to the Zendesk Customer Experience Trends Report 2024, 67 percent of business leaders understand that chatbots can help build stronger customer relationships. As we learn more about the benefits of chatbots for businesses and customers, choosing the right AI chatbot is more important than ever.

You may know about AI chatbots thanks to OpenAI’s launch of ChatGPT in 2022. While ChatGPT is certainly one of the most popular conversational, generative artificial intelligence (AI), it isn’t purpose-built for every use case. Our guide details what you need to know about the top AI chatbots—for business and personal use—and ChatGPT alternatives in 2024.

1. ChatGPT

Use case: General use

Models: GPT-3.5 and GPT-4

Price: Starts at $0 per month

When OpenAI released ChatGPT in late 2022, it became the fastest-growing consumer app ever. It arguably popularized artificial intelligence, making generative and conversational AI tools accessible to everyone.

ChatGPT offers writing, summarization, coding, research, and parsing capabilities. ChatGPT can also integrate with add-ons and plugins to access accurate information or use third-party services. Some notable plugins include:

  • OpenTable for restaurant reservations
  • KAYAK for travel bookings
  • Instacart for local grocery shopping
  • Speak for learning other languages

Since its launch, ChatGPT has rolled out new iterations of the original intent model, such as GPT-3.5 (available for free plans) and GPT-4 (available for ChatGPT Plus and other paid plans).

ChatGPT also offers DALL·E, an AI-powered image generator. Users can enter a prompt or describe an image through voice chat. Based on the description, DALL·E will generate an output, such as a picture, logo, or comic strip.

ChatGPT has a few noteworthy limitations. The GPT 3.5 data set doesn't extend past the end of 2022, so some information may not be current. It might lack real-world knowledge and struggle with understanding context, leading to occasional irrelevant responses. Additionally, it can be susceptible to generating biased or inappropriate responses when prompted to do so.

  • Free: $0 per month
  • Plus: $20 per user/month

2. Zendesk

Use case: Customer experience and employee experience

Model: Proprietary

Price: Starts at $55 per agent/month

Unlike many AI chatbot solutions, Zendesk bots are fast to set up, easy to use, and cost-effective because they don’t require technical skills or resources to deploy. They come pre-trained on real customer, IT, and HR support interactions specific to your industry, saving teams the time and costs of manual setup.

Zendesk chatbots elevate our industry-leading ticket management system by engaging customers (or employees) as the first point of contact and automating support across web, mobile, and social messaging channels—and they’re available on every Zendesk plan.

Taking it a step further, Zendesk Generative AI—powered by OpenAI—enables teams to:

  • Eliminate bot-building time by leveraging existing knowledge base content to deliver instant conversational responses using generative replies.
  • Elevate your brand value with a consistent tone and chatbot persona that reinforces your brand.
  • Optimize bot performance with intent suggestions based on past conversations that tell you what to automate.
  • Enhance the bot's engagement by choosing intents where the bot responds using generative AI versus a predefined flow.

Beyond conversational bots, Zendesk also offers generative AI tools for agents. Our AI-powered agent tools include intelligent routing and triage—sending requests to the right human agent based on language, intent (what a conversation is about), and sentiment (if it’s positive, neutral, or negative)—and sharing these insights with agents to provide helpful context and suggestions for how to solve the issue. AI can also surface similar tickets, turn a few bullet points into a full reply, and summarize conversations to boost productivity.

What’s more, Zendesk recently announced its acquisition of Ultimate, an industry-leading provider of service automation, to deliver the most complete AI offering for CX on the market. Ultimate’s AI agents automate up to 80 percent of support requests. They leverage any knowledge source and offer full customization to resolve even the most sophisticated use cases. Together, Zendesk and Ultimate will give companies the flexibility and control to deliver customer support their way—whether through fully autonomous AI agents, workflow automation, or human touch.

Gemini (originally Bard) is a conversational, generative AI chatbot developed by Google. Gemini's capabilities include engaging in multimodal dialogue (understanding and generating responses using different forms of communication such as text, speech, and images) and comprehending and producing content in multiple languages. It also possesses cultural understanding, enabling communication across diverse backgrounds.

Gemini can complete tasks like creating games, solving visual puzzles, and generating images with accompanying text descriptions. Its AI model is capable of logical and spatial reasoning—meaning it can follow instructions and understand logical relationships and spatial configurations, like in problem-solving tasks or game-play scenarios.

Gemini comes in three model sizes: Nano, Pro, and Ultra. Gemini Nano is optimized for smartphone and mobile devices, specifically for the Google Pixel 8. It can perform tasks like generating chat responses and summarizing text. Gemini Pro operates from Google's data centers, delivering fast responses and handling complex queries. Gemini Ultra is Google’s largest model, designed for highly complex tasks, coding, logical reasoning, and creative collaboration.

Gemini Advanced enables detailed conversations and understands more context than its previous versions. Gemini can serve as a personal tutor, generate step-by-step instructions, and assist with advanced coding scenarios. It can also analyze trends and help content teams brainstorm and create new content.

Google offers a free version of Gemini with the Pro 1.0 model that helps with common inquiries and integrates with Google apps. With the Ultra 1.0 model, the Advanced version targets highly complex tasks and will soon be available in Gmail, Docs, Slides, and Sheets (for Google One AI Premium subscribers).

Microsoft Copilot (formerly Bing Chat) is an AI-powered “companion” for web and mobile applications. With Copilot, users can ask questions and engage in follow-ups, get article summaries with personalized explanations, and generate emails and images. Copilot can also perform routine tasks with AI assistance, like suggesting meal plans.

Although some say it’s less conversationally creative than its competitors, the average user may find it handy for general planning, composing responses, and generating images.

Chatbot users can also view AI-powered results using the Bing search engine or app but have to download Microsoft Edge to get the full Copilot conversational experience. Copilot has a visual search and an enterprise-level chatbot that offers security features and citations for the answers it provides.

Microsoft Copilot has a free version, but there's a condition: Users must access the chatbot through Microsoft's Edge web browser. If the user has other browsers like Chrome, they will be restricted to five replies per conversation. Additionally, users can only engage in 300 conversations per day, with each thread capped at 30 replies, limiting extensive back-and-forth interactions.

  • Free: $0 per month
  • Pro: $20 per user/month

5. Claude

Use case: Creative writing

Model: Constitutional AI (CAI)

Price: Starts at $0.80/million tokens

A screenshot shows the login screen for Claude’s AI chatbot.

Image credit

Claude is a generative AI chatbot from Anthropic that uses Constitutional AI (CAI). The response bot software refers to itself as “self-contained,” meaning it responds to general queries without searching the internet. Claude uses the HHH system architecture, which stands for “helpful, honest, and harmless.”

Users can modify Claude’s behavior by prompting it with background knowledge to receive the desired responses. Claude comes in two paid models—Claude Instant and Claude 2—that can help users with text analysis, summarization, and creative content generation.

Since its original release in March 2023, Claude has upgraded to Claude 2.1, which was implemented in November 2023. Claude 2.1 showed an improvement over Claude 2.0, with a reduction in incorrect answers and improvements in understanding and summarizing long documents.

Claude 2.1 offers a range of capabilities but with some limitations. It has a daily limit of 200,000 tokens, roughly equivalent to 150,000 words. It lacks comprehensive world knowledge and cannot retain personal experiences. It operates within defined boundaries, struggling with adversarial or nonsensical input outside its domain.

Despite its conversational abilities, Claude is not a substitute for human intelligence. It’s incapable of offering psychological counseling, creative insight, strategic planning, or expert analysis.

Pricing:

  • Claude Instant: starts at $0.80/million tokens
  • Claude 2.0: starts at $8.00/million tokens
  • Claude 2.1: starts at $8.00/million tokens

6. Perplexity

Use case: General use

Models: GPT-4, Claude 2.1, Gemini, Llama, or proprietary

Price: Starts at $0 per year

A screenshot shows Perplexity’s AI chatbot interacting with a user about negotiating hotel check-in times.

Image credit

Perplexity is a general knowledge chatbot. It uses advanced natural language processing (NLP) and large language models (LLMs) to understand user queries and provide sources and citations to back up its responses.

Its search engine uses generative AI, including models from OpenAI and Meta's Llama. The conversational interface allows users to ask questions and get natural responses. The AI responds with summarized answers supported by source citations.

Perplexity also features Visual Perplexity, which allows the chatbot to respond to users using pictures and videos, and Llama Chat, an AI chatbot built on Meta’s Llama 2 model to support common programming languages and help developers with code.

Perplexity also features Copilot, a GPT-4-powered AI assistant. Users with a free account may only input five queries every four hours, while users on the paid plan get up to 600 queries on the free plan. Free-plan users can use their “Quick Search” more freely. It’s not powered by GPT-4 and has more rudimentary capabilities like serving up basic answers and search results to a question.

Perplexity.ai has its fair share of limitations and may occasionally generate factually inaccurate results. So, you might also end up with sentences that sound good statistically but include wrong information. Perplexity.ai may have issues understanding nuances of human language, such as sarcasm, humor, and cultural context.

They can even design bots for specific uses, such as a generative AI host that leads a text-based adventure game.

Character.AI chatbots do face certain challenges, such as system updates affecting individual behavior, memory retention issues, and occasional inaccuracies in the information they give to users. Image generation may exhibit inconsistencies and quality issues, while pop culture references may not always produce accurate results. Users should be mindful of these limitations to manage expectations during interactions.

It can even help users create personalized meal plans and recipes or generate to-do checklists. The bot also elaborates on questions, predicting the user’s next question. If users have an account, they can refer back to the thread for details later—even if they’ve made another query since.

While the bot creates general content using its own data, you can toggle the “Search web” button so its outputs align more closely with other online results, giving you more recent information. Because it's open-source software, users can access and modify the source code to customize the platform to fit their specific needs and add additional properties.

HuggingChat does come with a few limitations. It may produce factual errors and spelling mistakes, and it is sometimes prone to generating hallucinations—an uncommon phenomenon that occurs when an AI chatbot provides responses not grounded in reality.

It occasionally stops generating output mid-response or strays from the original topic, particularly with longer prompts. While it's useful for brainstorming, you may want to choose a chatbot that specializes in critical task generation.

Price: Free

Socratic by Google is a search-based chatbot and learning app for education and research. It provides AI support for high school and college students to help them better understand their assignments. Socratic uses Google AI and search technologies to connect students with educational resources, including websites for study guides, tutorial videos on YouTube, and step-by-step guides. It also uses text and speech recognition, so students have different ways to communicate what they need help with.

Once prompted with a query, Socratic shares a top match from Google and a detailed explanation, often with visualizations. The app also provides links to reputable online resources and study guides written by experts to enhance learning experiences.

While the Socratic AI chatbot by Google helps students tackle homework questions or understand complex topics, it does have its limitations. For starters, it mainly relies on information available online. So, it might provide outdated or inaccurate answers, especially for more niche subjects. Also, Socratic may not be able to provide the in-depth analysis you need for tricky or abstract concepts.

Another thing to consider is language support, which might not cover all languages or dialects, making it less accessible for some users. Like with any AI, there's always a risk of getting misinformation, so it's wise to double-check important facts. It may be best to use the tool as a way to complement your own critical thinking and research efforts.

25. Grok

Use case: Social media

Model: Grok-1

Price: $168 per year

A screenshot depicts a conversation with Grok, an AI chatbot.

Grok is a generative AI chatbot developed by xAI, the artificial intelligence company owned by X (formerly Twitter). The bot is named after the science-fiction novel “Stranger in a Strange Land,” and its persona is inspired by the comedic novel “The Hitchhiker’s Guide to the Galaxy.”

Grok uses real-time knowledge through the X social media platform to answer questions and suggest related follow-up questions for users to ask. It’s designed to answer questions with wit and humor, differentiating itself from other AI chatbots.

Although Grok's access to real-time X posts reinforces its credibility, it is also susceptible to inaccurate or unverified information. It lacks the safety guardrails of competing chatbots, allowing users to get answers about “spicy” topics that most other AI chatbots typically reject.

Grok’s capabilities extend beyond conventional responses. It can draft emails, debug code, and generate ideas, all in conversational, human-like language. It can also handle multiple queries simultaneously. Despite its current limitation to text inputs, Grok is poised for future enhancements, including visual and audio capabilities.

The AI chatbot is currently in the beta stages and is only available for X Premium+ users. The xAI team that created Grok provides feedback forms for users to share their experiences. The goal of Grok is to serve as a research assistant and data processor, helping users innovate with new ideas.

  • X Premium+: $168 per year on web (based on U.S. pricing)

What to look for in an AI chatbot

The best chatbot platform for your business depends on several factors. Let’s explore some questions and considerations to understand your needs and limitations when choosing an AI chatbot.

A graphic shows icons with considerations for choosing an AI chatbot.
  • Ease of setup: Look for a pretrained AI chatbot that works right out of the box. Determine if it requires developer support that may entail manual training and configuration.
  • AI model sophistication: Know the data the AI bot is trained on. High-quality AI chatbots often utilize NLP and ML algorithms to understand inputs and generate contextually relevant responses. Check for features like context retention, customer sentiment analysis, and generative AI.
  • Integration capabilities: Ensure the AI chatbot seamlessly integrates with your existing systems and software. Look for compatibility with your messaging software, websites, CRM systems, and other tools relevant to your business. Evaluate the availability of APIs and integration options that facilitate connections with third-party applications, enabling a cohesive workflow.
  • Security and data privacy: Prioritize security features to safeguard sensitive information. The AI chatbot should comply with data protection regulations and implement encryption protocols to secure user interactions. Verify the platform's privacy policies to ensure it handles user data responsibly and transparently. Look for options to customize data retention and privacy settings.
  • Reporting and analytics: Robust reporting and analytics capabilities are essential for monitoring the chatbot's performance and gaining insights into user interactions. Check for features like conversation logs, user engagement metrics, and sentiment analysis reports. These analytics can help you understand user behavior, identify areas for improvement, and measure the overall effectiveness of the chatbot.

Choose an AI chatbot with the right features that align with your business needs. It’s also important to consider factors like scalability, quality chatbot support and updates, and the user experience.

How to create a chatbot: AI chatbots vs. traditional chatbot builders

Traditional chatbots require the creation of long, extensive flows to guide customers through step-by-step journeys to reach a resolution. These flows are difficult to maintain and scale as more use cases are added. Additionally, manual training on customer intent can require hours of admin time.

On the other hand, AI chatbots like Zendesk’s are pre-trained to understand customer intent from the get-go. There’s no need to build lengthy and complex flows. Instead, the bot can switch between answer-led flows based on customer intent, making it easier to scale and maintain the bot. Additionally, with generative AI, admins can save time by connecting the bot to a help center. The bot can easily understand customer queries, search the help center for the necessary information, and craft a response—all without the need to create long flows.

For example, you can create an AI chatbot in a few clicks with the Zendesk bot builder.
