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

ChatGPT
Best AI chatbot overall
ChatGPT is a hugely successful conversational AI chatbot released in November 2022 by OpenAI. It has advanced capabilities, such as performing writing tasks well, including composing emails, essays, resumes, and lists. It is also highly proficient in STEM tasks like writing and debugging code and solving complex math equations.

Copilot outperformed earlier versions of ChatGPT because it addressed some of ChatGPT's biggest pain points at the time, including a lack of Internet access and a knowledge cutoff.

Microsoft Copilot
Best ChatGPT alternative
In February 2023, Microsoft unveiled a new AI-improved Bing, now known as Copilot. This tool runs on GPT-4 Turbo, which means that Copilot has the same intelligence as ChatGPT, which runs on GPT-4o.

In October, Copilot rebranded, making its UI much more modern, welcoming, and user-friendly. The rebrand also came with a ton of new features, including being able to chat using Copilot Voice, Copilot's version of ChatGPT's Advanced Voice Mode, but for free.
Anthrophic's Claude
Best AI chatbot for prviacy
Anthropic launched its first AI assistant, Claude, in February 2023. Like its leading competitors, Anthropic can answer prompts conversationally for anything you need assistance with, including coding, math, writing, research, and more.

Although I have given this chatbot various superlatives in the past, including the best AI chatbot for image interpretation and the best for chatting, I would say that -- at the moment -- the biggest advantage of this chatbot is that it prioritizes privacy.

Anthropic has made it as transparent as possible that it will never use a user's prompts to train its models unless the user's conversation has been flagged for Trust & Safety review, explicitly reported the materials, or explicitly opted into training. Furthermore, Anthropic has never automatically used user data to train its models.



Beyond its transparency, it is also a highly capable chatbot. If you want to use the chatbot regularly, upgrading to Claude Pro may be a better option, as it offers at least five times the usage limits compared to the free version for $20 a month.

Perplexity.ai
Best AI chatbot for search
Perplexity AI is a free AI chatbot connected to the internet that provides sources and has an enjoyable UI. As soon as you visit the site, using the chatbot is straightforward -- type your prompt into the "ask anything" box to get started.

A title above the textbox reads, "Where knowledge begins" -- and it could not be more fitting.
Jasper
Best AI chatbot for businesses and marketers
Jasper is specifically for users looking to incorporate an AI chatbot into their workflow -- there is no free plan, and you can't even access the chatbot without paying up. For example, when I tried using the AI, I was met with dead ends unless I subscribed. The least expensive option, the Creator plan, is geared towards freelancers and solo-preneurs and costs $49 a month. However, the investment may be worth it if you rely on an AI chatbot to generate copy for your business.
You.com
Best AI chatbot for LLM testing
You.com (previously known as YouChat) is an AI assistant that functions similarly to a search engine. Like Google, You.com lets you enter any question or topic you'd like to learn more about, and you're immediately met with real-time web results, in addition to a conversational response.

For example, when I asked, "Can you share some pictures of adorable dog breeds?", the chatbot provided six web links, seven pictures it pulled from the web, a conversational answer, and related news.
