5 Best AI Chatbots in 2025

AI chatbots have gotten a ton of attention since the launch of OpenAI's ChatGPT, and they may be what most people think of when they think of artificial intelligence.

However, ChatGPT is far from the only artificial intelligence (AI) chatbot on the market, and its launch sparked a parade of competitors, some of whom seemed to be waiting for such a moment to unveil their own large language models (LLMs).

In this article, we'll discuss what an AI chatbot is, review some AI chatbot stocks you can invest in, and explore whether you should invest in AI chatbot technology today. If you're wondering about the best AI chatbots, keep reading.

What are AI chatbots?

What are AI chatbots?

A chatbot is an AI-based computer program that uses natural language processing to communicate with humans using text. Chatbots are a common tool for customer service, internet search, and other routine tasks for internet users. Businesses also use AI chatbots internally to help automate workflows and other tasks.

Their utility has evolved in recent years as artificial intelligence has improved, and large language models have been trained to process complex questions and understand nuance. You can even make your own AI chatbot using the Python coding language.

As AI chatbots have improved, the market potential for the technology has increased, as can be seen in OpenAI's recent valuation at a reported $157 billion, with investors including Microsoft (MSFT 0.5%) and Softbank (SFTB.Y 0.35%).

With OpenAI demonstrating the capability of AI chatbots, investor interest in the technology has soared. Keep reading to see how you can get exposure to AI stocks in the chatbot space.

1. Microsoft

Through its partnership with OpenAI and ChatGPT, Microsoft has established itself as a clear leader in the AI chatbot race.

The company is working quickly to integrate ChatGPT into a wide range of its products. That includes Azure, its cloud infrastructure service, the new Bing, and its Edge browser. It's also reportedly working on adding ChatGPT features to its Office suite, which includes products like Word, Excel, PowerPoint, and Outlook.

However, Microsoft's biggest move in AI chatbots may be the launch of its own Copilot, a digital assistant available across Microsoft's applications.

Microsoft CEO Satya Nadella has said on multiple occasions that he sees AI as a platform shift, and the company has doubled down on its relationship with OpenAI after investing more than $13 billion in the startup over the years.

After his company missed out on the shift to mobile, Nadella is committed to not making the same mistake twice. Expect Microsoft to continue to spend aggressively on ChatGPT and other AI tools.

If you're looking to invest in ChatGPT, Microsoft gives you the most direct way to do so.

2. Alphabet

Alphabet (GOOG 0.86%)(GOOGL 0.82%) has been investing in artificial intelligence for years. It acquired DeepMind, an AI research lab, in 2014, and it's spent billions on its autonomous vehicle division, Waymo.

After the release of ChatGPT in November 2022, Alphabet moved quickly to counter what seemed to be the most serious threat to Google Search yet, calling a "Code Red" meeting and bringing back founders Sergey Brin and Larry Page to formulate a strategy.

After some missteps, Google launched Gemini in December 2023, which is available through Google's search bar. It's also added AI overviews to Google Search and enabled AI mode on search, allowing users to tap into the power of Gemini.

Alphabet is monetizing Gemini in a number of ways, including selling premium subscriptions, through application programming interfaces (APIs) that it allows developers to use, and integrating with Google's Cloud Platform. Currently, it seems like a way for it to protect its monopoly on search, and it could help monetize traffic that doesn't generate ads.

3. Amazon

Amazon (AMZN -0.61%) hasn't found success with its own chatbot. The company has launched Amazon Q, a generative AI assistant, and Rufus, a shopping assistant.

However, Amazon is also a major investor in Anthropic, the maker of the chatbot Claude, which is considered by some to be the closest challenger to ChatGPT. In November 2024, Amazon said it would invest $4 billion in Anthropic after investing $4 billion in the company earlier in the year. As of July 2025, there were reports circulating that it could make another multi-billion-dollar investment in the AI start-up.

As part of the previous investment, Anthropic will use Amazon's Trainium and Inferentia chips to train its AI models.

Amazon has also invested in Bedrock, a managed cloud service in Amazon Web Services (AWS) that builds AI applications like chatbots.

4. Baidu

Baidu (BIDU -0.76%) is often known as the Chinese Google, and the company's move into AI chat shows that it has more than search in common with Alphabet.

In February 2023, Baidu joined the fray in AI chat, announcing that it would also launch its own chatbot that would serve as a complement to its search engine.

Known as ERNIE bot, the chatbot was released in March 2023. As of June 2024, the company said it had attracted 300 million users.

Baidu first began developing its language model in 2019, and the technology has advanced significantly since.

ERNIE was launched as a standalone application first, but eventually will merge with its search engine, choosing chatbot-generated results rather than just links. Baidu made Ernie open-source in June 2025.

The company is also investing aggressively in other AI technologies like self-driving cars and semiconductors, and it views artificial intelligence as a valuable growth market.

5. Meta Platforms

Meta Platforms (META 0.82%) has invested significant resources in artificial intelligence as well, but most of that funding has gone toward recommendation AI, the algorithms that determine the content served to users on Facebook and Instagram.

More recently, the company launched LLaMa, an open-source large language model. Though LLaMa is not a chatbot, it powers Meta's chatbot, Meta AI, which is available across Meta's properties, including Facebook, Instagram, Messenger, and WhatsApp. Meta AI reached a milestone of more than 1 billion monthly active users in May 2025.

CEO Mark Zuckerberg sees conversational and generational AI as a huge potential market, and the company plans to continue investing in chatbots and related areas. It's been aggressively hiring AI researchers, and it acquired 49% of Scale AI, a data-labeling specialist, for $14 billion in June.
