Best AI Chatbots: From ChatGPT to Microsoft Copilot

These two LLMs are built on top of the mistral-7b LLM from Mistral and and llama2-70b LLM from Meta, the latter of which appeared just above in this list. Just ensure you don’t bombard it with tons of questions at once, as it does deal well with this kind of informational overload and sometimes crashes – at least in our experience. Like ChatGPT, Gemini has been powered by several different LLMs since its release in February 2023. First, it ran on LaMDA – which one former Google employee once said was sentient – before a switch to PaLM 2, which had better coding and mathematical capabilities.

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

• To quote the late, great Tina Turner, ChatGPT is “simply the best.” It wasn’t the first AI chatbot, but it was the first to package an LLM as advanced as this into an approachable, user-friendly chat interface.
• Unlike Google’s Gemini and OpenAI’s GPT-4 language models, Llama 2 is completely open source, which means all of the code is made available for other companies to use as they please.
• Claude’s ability to understand and respond to complex questions is bolstered by its multimodal capabilities, including analyzing documents, photos, and graphs.
• One of the things that makes Copilot so great is the fact that it’s so accessible.

If you need an AI content detection tool, on the other hand, things are going to get a little more difficult. No AI content detection tool is 100% accurate and their results should be taken with a pinch of salt – Even OpenAI’s text classifier was so inaccurate they had to shut it down. Anthropic is pioneering a concept called “constitutional AI” – which is effectively a way to make an LLM safer by ensuring it “gains” values via a constitution provided.

Gemini Live is Google’s answer to Advanced Voice Mode, and performs the same function. It’s free for all Gemini users on Android, as well as through the web app, and can converse in more than four dozen languages. In China millions of smartphone users frequently spend hours interacting with Xiaoice, a Microsoft-created chatbot which exchanges text messages with its users.

Google Bard

Claude was also the first chatbot to introduce a collaboration space, in this case the Artifacts feature, which enables the user to effectively preview and iterate upon the AI’s outputs in real time. Copilot has since introduced a collaborative space, as has ChatGPT (the Canvas feature). Whether Perplextity will be able to continue providing this service is unclear, on account of its mounting legal troubles.

From MOOCs (Massive open online courses) to the use of iPads in schools, there’s no doubt that technology is changing the way that we learn. From changing the way kids learn in schools to picking you out the perfect meal this evening, here are the seven of the most interesting chatbots doing the rounds at the moment. As of Google’s announcement at Google I/O, Bard is open to the public and now powered by PaLM 2, the newest version of Google’s LLM. While Bard is free to use, which is a major plus, it loses points for inaccuracy and responses that are less nuanced than ChatGPT and Bing. Google scrambled to release its own AI chatbot, Bard, following the surprise success of ChatGPT and subsequent Bing Chat. After a rocky start that was called “botched” and “rushed,” Bard has almost caught up to its competitors.

• But, Jasper only provides a 7-day free trial, with paid subscriptions starting at $50 a month after that.
• 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.
• We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites.
• It’s designed to be capable of highly complex tasks and, as such, can perform some impressive computational feats.

For example, asking, “What came first, the chicken or the egg?” led to ChatGPT labeling the chat as “Chicken or Egg?” That way going back to a previous conversation for follow-up interactions is really easy. What’s more, ChatGPT can be accessed on PC or mobile, making it easy to interact with. This list details everything you need to know before choosing your next AI assistant, including what it’s best for, its pros and cons, cost, its large language model (LLM), and more. Whether you’re new to AI chatbots or a regular user, this list should help you discover a fresh option you haven’t tried before. 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).

Copilot serves as Microsoft’s flagship AI assistant, available through iOS and Android mobile apps, the Edge browser, as well as a web portal. Like Gemini, Copilot can integrate across Microsoft’s 365 app suite, including Word, Excel, PowerPoint, and Outlook. It first debuted in February 2023 as a replacement for the retired Cortana digital assistant.

Google Gemini

This model has proven significantly more powerful than the version available to ChatGPT users at the free tier, especially as a tool to collaborate with on longer-form creative projects. Users have already done some amazing things with it, including programming an entire 3D space runner game from scratch. As for the speed, it’s pretty slow compared to the rest of the chatbots.

This one’s obvious, but no discussion of chatbots can be had without first mentioning the breakout hit from OpenAI. Ever since its launch in November of 2022, ChatGPT has brought AI text generation to the mainstream. No longer was this a research project — it became a viral hit, quickly becoming the fastest-growing tech application of all time, gaining more than 100 million users in just two months. While Microsoft’s AI is primarily powered by OpenAI’s models, the company has made Copilot its own thing.

Google Gemini and Gemini Advanced

While competitors like Microsoft Copilot and Google Gemini offer strong alternatives, ChatGPT stands out for its seamless combination of advanced features and simplicity. The breadth of ChatGPT’s applications have proven unmatched in the AI chatbot category. As you might expect from an app designed to create intimate connections between humans and machines, Replika has faced controversies. In January, users reported instances of sexually aggressive interactions.

In the past, an AI writer was used specifically to generate written content, such as articles, stories, or poetry, based on a given prompt or input. An AI writer outputs text that mimics human-like language and structure. On the other hand, an AI chatbot is designed to conduct real-time conversations with users in text or voice-based interactions. The primary function of an AI chatbot is to answer questions, provide recommendations, or even perform simple tasks, and its output is in the form of text-based conversations.
