The best AI chatbots: ChatGPT, Gemini, and more

The major difference is that Jasper offers extensive tools to produce marketing copy. The tool can check for grammar and plagiarism and write in over 50 templates, including blog posts, Twitter threads, video scripts, and more. Jasper also offers SEO insights and can even remember your brand voice. Other perks include an app for iOS and Android, enabling you to tinker with the chatbot while on the go. Footnotes are provided for every answer with sources you can visit, and the chatbot’s answers nearly always include photos and graphics. When you click on the textbox, the tool offers a series of suggested prompts, mostly rooted in news.

It also has tools that can be used to improve SEO and social media performance. Now, Gemini runs on a language model called Gemini Pro, which is even more advanced. We recently compared Gemini to ChatGPT in a series of tests, and we found that it performed slightly better when it came to some language and coding tasks, as well as gave more interesting answers.

Best chatbot for image-generation: Meta AI

The best AI chatbot if you want a chatbot that will not use your data unless explicitly opt-in. While there are plenty of great options on the market, if you need a chatbot that serves your specific use case, you can always build a new one that’s entirely customizable. HuggingChat is an open-source chatbot developed by Hugging Face that can be used as a regular chatbot or customized for your needs. And, while it’s fun, we wouldn’t trust the information coming out of it as much as we would with Gemini or ChatGPT (although that’s not saying much). When you start typing into the chat bar, for example, you’ll get auto-fill suggestions like you do when you’re using Google.

The best AI chatbots of 2025: ChatGPT, Copilot, and notable alternatives

Using my findings and those of other AI experts at ZDNET, I have created a comprehensive list of the best AI chatbots on the market. AI chatbots have a near-endless list of use cases and are undoubtedly very useful. The latest Grok language mode, Grok-1, is reportedly made up of 63.2 billion parameters, which makes it one of the smaller large language models powering competing chatbots. ChatGPT also lets you create AI images with its DALL-E integration, and the chatbot also released an AI search tool that works in a similar way to Perplexity AI. All of these useful capabilities, and OpenAI’s commitment to continually improving its product offering, are all factors that help ChatGPT to remain the best chatbot on the market in 2025.

According to GM and industry experts, LMFP cells could help bring the cost of electric vehicles close to — or even on par with — gas-powered cars. Making EVs accessible to a broader range of drivers without sacrificing range or performance. Whole Foods has joined the Facebook Messenger party by coming up with a way to turn text or even emoji-based searches (finally, a non-lewd use for that eggplant emoji!) into suggestions. Enter a taco emoji, for instance, and you’ll receive links to recipes featuring tacos. Anthropic was founded by former members of OpenAI, so they know their way around an LLM. Currently Claude is only available through select business partnerships like Slack and Zoom, so individuals don’t have access yet.

It does this using GPT-3  (not GPT-4, yet), a neural network or machine learning algorithm that can learn and make intelligent predictions by utilizing an enormous database of information and billions of parameters. To curate the list of best AI chatbots and AI writers, I considered each program’s capabilities, including the individual uses each program would excel at. The best AI chatbot overall and a wide range of capabilities beyond writing, including coding, conversation, and math equations. The app, available on the Apple App Store and the Google Play Store, also has a feature that lets your kid scan their worksheet to get a specially curated answer.

While not quite as powerful as o3, o4 mini is a lighter-weight and cheaper model to use. They’re extremely useful tools that give you natural-sounding responses based on your input. Nowadays, we see a bunch of chatbots popping up all over the place with varying degrees of effectiveness.

Its plans run on three different LLMs Gemini Nano, Gemini Pro, and Gemini Ultra. The most advanced LLM, Gemini Ultra, was released at the start of 2024 and boasts more advanced reasoning capabilities and a larger memory footprint than previous models, and even beats GPT-4 when it comes to speed. Companies can also use ChatGPT to build their own chatbot, helping them streamline a range of processes from customer service to lead generation. At DevDay 2023, OpenAI launched GPTs – custom chatbots that will act and respond in specific ways based on the instructions and knowledge that you give them. It’s pretty easy to learn how to make a GPT, so if you’ve got ChatGPT Plus, we’d advise giving it a go – soon, you might find yourself selling it on the GPT store.

You’ll need to upgrade to a different plan to create a personal AI for work, but the personal option is free. The large language model powering Pi is made up of over 30 billion parameters, which means it’s a lot smaller than ChatGPT, Gemini, and even Grok – but it just isn’t built for the same purpose. The best thing about Copilot for Bing is that it’s completely free to use and you don’t even need to make an account to use it. Simply open the Bing search engine in a new tab, click the Bing Chat logo on the right-hand side of the search bar, and then you’ll be all set. Llama 2 – the second member “Llama” family of LLMs – was released back in July 2023. Since then, it’s been incorporated into several different systems, thanks to the fact that it’s open source and free to use if you’re developing your own language model or AI system.

What is Grok? Elon Musk’s controversial ChatGPT competitor, explained

• Formerly known as Bard, one of ChatGPT’s main rivals is Google’s Gemini (and its $20/month Gemini Advanced premium subscription).
• The most unsettling of which are reports by users that Copilot sometimes responds in ways that feel emotional.
• AI chatbots vary in their abilities and uses based on a variety of factors, including the language model they’re built on top of, their pre-defined functionality, and access to data sources (such as the internet).
• Many of those features were previously limited to ChatGPT Plus, the chatbot’s subscription tier, making the recent update a huge win for users of the free version.
• The Google One AI Premium Plan includes other perks besides Gemini Advanced, such as Gemini in Gmail and Docs, 2TB of storage, and unlimited Magic Editor in Google Photos.

Now that ChatGPT comes with a Bing plugin, it can browse the internet, giving you up to date search results, whereas before its source of data was cut off after September 2021. For instance, Microsoft Azure users can use Llama 2 to build chatbots and other AI-powered applications, while Perplexity AI – another chabot to make our list – is powered by language models that are built upon Llama 2. Dictation support enables users to input prompts verbally, streamlining workflows for those who prefer or need voice-based interaction.

Remember the movie Her where Joaquin Phoenix’s character falls in love with his AI companion? Using its proprietary LLM and “scripted dialog content,” Replika lets users create their own personal AI companion. Once you wrap your head around that, you’re ready to learn about the numerous stories of people developing romantic relationships with their Replika avatars.

Xiaoice uses deep learning technology to pair up user queries with human-generated responses mined from the Internet. It can even track real life details about its users, such as who they are dating or what they do for a living, and return to these topics in later conversations – such as asking how a person is coping after losing their job. Google Gemini, the tech giant’s next-generation AI model, is redefining the standard for text-based interactions. As the latest evolution of Google’s AI capabilities, Gemini combines conversational fluency, advanced reasoning, and deep integration with Google’s ecosystem.
