ChatGPT #
Pros & Cons
ChatGPT, which has almost become synonymous with AI, runs on OpenAI's powerful 5-series of LLMs. It produces incredibly comprehensive responses with a friendly attitude. From complex reasoning to creative writing, ChatGPT excels at providing you with a foundation of content to build upon and shape as you see fit. It also stands out for its robust customization options, which let you personalize ChatGPT, and its comprehensive memory capabilities.
Why We Picked It
Price and value: ChatGPT isn't as generous as Gemini with its free plan, but its paid plans offer more usage, particularly if you're a vibe coder. We appreciate the variety of subscription options, which let you spend anywhere from $8 to $200 per month, depending on how much usage you need and which features you want.Models: ChatGPT's latest flagship model is GPT-5.6. It's available across the lightweight Luna, balanced Terra, and flagship Sol variants, for which you can set the intelligence levels. ChatGPTImages 2.0is its image generation model.Performance and speed: GPT-5.6 is a best-in-class AI model. It can think deeply about even the most complex requests and deftly handle a variety of coding tasks. It's capable of responding quickly, too.Capabilities and features: ChatGPT's deep research feature is excellent, churning out lengthy reports on any topic. It also offers an impressive array of features, including a robust AI coding interface and a variety of integrations. However, its integrations are accessible only within ChatGPT, not in other apps, unlike Copilot and Gemini.Media generation: ChatGPT goes toe-to-toe with Gemini's best-in-class image-generation models, delivering consistently high-quality images and robust editing tools. ChatGPT no longer supports video generation, as OpenAI discontinued Sora 2.Voice: You can voice chat with ChatGPT on desktop or mobile, and the voice quality impresses, even though it's still recognizable as AI. You can customize both ChatGPT's voice and personality more than with competitors, but these settings would be more accessible during voice chats.### Who It’s For
Chatters: If the main reason you use AI is for conversation, ChatGPT's approachable tone and in-depth customization options make it, by far, the best partner among mainstream chatbots.Independent users: If you don't use much software within Google's or Microsoft's ecosystem, the extra features of Copilot or Gemini won't matter to you. ChatGPT is much more attractive from a value standpoint if you can get by with just the integrations it supports.### Specs & Configurations

Google Gemini #
Pros & Cons
Gemini offers the strongest value of any AI chatbot. It performs well across all types of prompts we test, but its Nano Banana image editing and generation tech is the best we've seen in a chatbot. An impressive suite of useful integrations across pretty much every app, plus 2TB (or more) of for premium users, rounds out the experience.
Workspacecloud storage### Why We Picked It Price and value: Among AI chatbots, Gemini is the most generous. Its free plan includes access to some of its top models (such as Nano Banana Pro and 3.1 Pro) as well as 15GB of Google Drive storage, among many other things. Paid plans significantly expand usage limits and cloud storage allocations, which no other premium chatbot plan offers to the same degree.Models: Gemini has two primary model series: Flash and Pro. The current latest versions are 3.7 Flash and 3.1 Pro. Flash is best for everyday tasks, while Pro can use complex reasoning to handle complicated requests. Additionally, Gemini offers its Nano Banana image generation models and its Veo video generation models.Performance and speed: Gemini's Flash model is blazingly fast, whether you're coding or just asking questions. However, Gemini's models are also smart enough to handle complex reasoning, deep research, and image recognition, among other things, without issue. While Gemini's models aren't best-in-class in terms of intelligence, they're more than smart enough for most tasks.Capabilities and features: Gemini supports an exhaustive number of integrations with almost all of Google's many apps and services. As such, it's ideal if you work deep within the Google ecosystem. As you might expect, Gemini also has a bevy ofAI searchfeatures withinGoogle Searchitself, which enables you to more effectively hunt down information. Lastly,Gemini's AI agent, Spark, stands out as the most effective one I've tested to date.Media generation: If you're after best-in-class AI image or video generation, Gemini leads the pack. ItsNano Banana ProAI image generation model creates the most realistic AI images available today. And Gemini's Veo 3.1 AI video model far outclasses the competition, generatingvideos so lifelike you can easily mistake them for real clips.Voice: Gemini supports voice chat, called Gemini Live, but only on its mobile apps, not the web interface. On the web, it limits you totext-to-speechfunctionality. The voice chat experience on mobile is seamless, thanks to its many customization options, generally high-quality voices, and straightforward interface.### Who It’s For
Google users: If you already rely on Google apps such as Docs, Drive,Gmail, and Sheets, Gemini is the chatbot for you. Its rich integrations make everything from curating playlists to generating emails as simple as a single click.Media generators: If your favorite thing to do with chatbots is generate (or edit) images and videos, Gemini's best-in-class technologies make it the top option.### Specs & Configurations

Microsoft Copilot #
Pros & Cons
uses powerful LLMs from OpenAI and combines them with Bing web-scraping data to deliver up-to-date responses to your prompts. It's available on mobile apps, the web, and . For an extra subscription fee, Copilot also works inside apps, suggesting edits or formulas and even generating illustrated presentations based on your text prompts.
CopilotWindowsMicrosoft 365### Why We Picked It
Price and value: Considering just how expansive Copilot's feature set is, Copilot subscriptions offer superb valuable. Furthermore, Copilot is part of Microsoft 365, so you also get access to the Microsoft Office suite and plenty ofOneDrivestorage when you sign up. However, Microsoft 365 isn't quite as generous with cloud storage as Gemini subscriptions.Models: OpenAI's models power Copilot's different modes (Search, Smart, Study and learn, and Think deeper), but Microsoft isn't always up front about which ones. For example, Microsoft says Smart mode relies on GPT-5 while vaguely stating that the "latest reasoning models from OpenAI" enable the Think deeper mode.Performance and speed: Copilot isn't the fastest chatbot, but it responds quickly enough that you won't have to wait long. It also has enough intelligence to answer most questions without issues. Thanks to its core OpenAI tech, it performs competently, though not exceptionally, across the board.Capabilities and features: Like Gemini, Copilot's biggest appeal is its deep integration across the Microsoft ecosystem. You can find Copilot in almost every Microsoft product, including Windows. Furthermore, the breadth of Copilot's features is impressive, offering everything from AI-powered 3D modeling to text-to-speech and much more.Media generation: Copilot, like ChatGPT, doesn't generate videos, but it does edit and generate images. It does so competently, but top models from ChatGPT and Gemini provide better results. Although they aren't technically part of the Copilot ecosystem, Microsoft's in-house line ofMAI-Image modelsalso generates quality, if not best-in-class, images.Voice: Copilot supports voice chat on both mobile and the web. The quality of its voices generally impresses, even if they don't sound perfectly human. Copilot's voice chat interface also makes it easy to adjust settings on the fly. Furthermore, it also has some unique features, such as the ability to give your AI voice an avatar.### Who It's For
AI web browser fans: Microsoft's Copilot-powered Edge is one ofthe best AI web browsersavailable because it combines AI features and traditional browser conveniences so well. Importantly, it's the default browser on Windows, too.Microsoft users: Choose Copilot to leverage AI across the Microsoft ecosystem. It's an especially good option if you spend a lot of time using Microsoft 365 apps, such as Excel, PowerPoint, Word, and more.### Specs & Configurations

Perplexity #
Pros & Cons
Although Perplexity brands itself as an "answer engine" rather than an AI chatbot, it has all the features we expect from one, including complex reasoning, deep research, file processing, image recognition, media generation, and more. It's less conversational than other chatbots on this list, but it excels at , thanks to generally accurate responses and an excellent user interface. Meanwhile, Perplexity's web browser bakes AI right in.
web searchComet### Why We Picked It Price and value: Although you can use Perplexity for free, you don't get access to most of its features, such as its AI agent, Computer, or model selection. Premium Perplexity subscriptions also include Comet Plus (an upgraded version of the company's AI web browser) and higher usage limits. However, only two options are available (Pro for $17 per month or Max for $167 per month, billed annually), so you don't have much flexibility.Models: Perplexity uses its in-house model line. Sonar (its latest version is Sonar 2) can do everything from deep research to web searching and more. However, part of the magic of Perplexity is that you can use other models with it, including those from ChatGPT, Claude, and Gemini. It's a great place to compare AI models.Performance and speed: Perplexity excels at deft, quick web searches rather than at more traditional chatbot tasks. You can still use it to crunch through tough equations or have a casual conversation, but it's not as good at that as competitors. However, if you're looking for a chatbot to help you do research, Perplexity is a top performer.Capabilities and features: Perplexity offers a unique AI agent, Computer, and an AI web browser, Comet. It can also help you track relevant news and stay up to date. Like ChatGPT, Perplexity lacks the meaningful integrations you get with chatbots, such as Copilot and Gemini.Media generation: You can generate both images and videos with Perplexity via third-party models. For the best results, select Nano Banana Pro or Veo 3.1. Perplexity's other options, such as the out-of-date GPT-Image-1, won't perform as well. However, keep in mind that you need a premium subscription to use Veo 3.1 and the top Max subscription for Nano Banana Pro.Voice: Perplexity supports voice chat on desktop and mobile, and you can switch voices easily. Voice quality matches that of other chatbots, meaning it's generally high-quality, albeit imperfect. However, you can't share your screen with Perplexity during a voice chat, unlike with Copilot, ChatGPT, and Gemini.### Who It's For
Comparison shoppers: Perplexity supports models from a range of AI companies, including Google and OpenAI, making it a great place to try out models and see which work best for your needs.Researchers: If using AI to find answers to all the questions you might have on a topic sounds interesting, Perplexity specializes in AI search. Just don't expect casual conversations at the level of ChatGPT or Gemini.### Specs & Configurations

Claude #
Pros & Cons
Claude offers a host of interesting features, such as AI-assisted and , but its defining attribute is its coding acumen, especially within the Claude Code app. With agentic tech, incredibly intelligent models, and large context windows, Claude is the chatbot of choice for many professional programmers and alike. Its usage limits can be aggressive, however, so you might have to spring for an expensive subscription.
designvisualizationvibe coders### Why We Picked It
Price and value: You can use Claude for free, but it lacks some of the features of other chatbots' free plans, such as cloud storage with Copilot and Gemini. Furthermore, Claude's premium plans start at $20 per month, while many competitors offer cheaper options. Nonetheless, for coders who need lots of usage, Claude's top-tier plans aren't more expensive than those of its closest competitor, ChatGPT.Models: Claude's flagship models are the Opus line for complex tasks and the Sonnet line for day-to-day use. The current latest versions are Opus 5 and Sonnet 5.Fable 5(and Mythos 5) are Claude's flagship (and most expensive) models.Performance and speed: Although Claude isn't as lightning-fast as Gemini, its intelligence is impressive, outperforming Copilot, Gemini, Grok, and Perplexity.Capabilities and features: Claude excels at coding and offers a variety of features. For example, its desktop app supports a suite of unique integrations. You can use Claude Design to dream up an interface for an app or generate marketing materials, among many other things. Claude even has an agentic assistant, Cowork, that runs locally on your computer.Media generation: Claudecan generate many kinds of assets and visualize all sorts of things via Claude Design, but it doesn't support image or video generation in the traditional sense. Claude renders its visuals using HTML rather than generating images or videos, so you need to look elsewhere for that functionality.Voice: You can voice chat with Claude on both desktop and mobile. Changing voices or the speaking pace is easy to do right within the voice chat interface, and the voice quality generally matches what you get from other chatbots. However, you can't share your screen with Claude during voice chats, unlike with ChatGPT, Copilot, and Gemini.### Who It's For
Coders: Many people love Claude (Claude Code in particular) for its helpfulness as a programming tool. In fact, Claude Code is easy enough to use that itdoesn't requireany programming experience.The privacy-conscious: If you're especially wary of funneling your data into Google, Microsoft, or OpenAI servers, Anthropic's policies are straightforward and give you meaningful control over your personal information.### Specs & Configurations

Grok #
Pros & Cons
Grok automatically searches X when responding to prompts, providing deeper social media integration than competitors. It's also loose in its moderation, meaning you can chat about a taboo subject or get a relatively neutral evaluation of a hot topic. Grok performs competently in complex reasoning, file processing, and web searching. Grok also has NSFW features, including and permissive image and video generation.
datable companions### Why We Picked It Price and value: You can use Grok for free, but expect limited usage and missing features. Premium Grok subscriptions, however, are affordable and come with enough options that everyone can find something that works for them. Grok also has a number of NSFW features, giving it unique value in the AI chatbot market.Models: Grok has different modes (Auto, Expert, and Fast) you can engage depending on the type of prompt you're about to send, but they all run on Grok's self-titled Grok model. The latest version of Grok is Grok 4.6.Performance and speed: Like Copilot, Grok is neither the fastest nor the smartest chatbot, but it can handle the vast majority of tasks you throw at it. If you want to do serious research orbuild an app, though, you're better off with competitors like ChatGPT or Claude.Capabilities and features: Unlike most AI chatbots, Grok can search X when responding to prompts, so you can easily get a sense of community sentiment. Grok also excels at NSFW tasks, which other chatbots don't support at all. You can chat with3D AI companions, generate NSFW media, or even search for explicit videos with Grok.Media generation: Grok can generate both images and videos, including NSFW content. While what it can generate is unique, its quality isn't on par with the best-in-class image and video generation models from Google or OpenAI. However, media generation with Grok is, at least, serviceable.Voice: Grok allows for voice chat on both desktop and mobile. You can also change any relevant voice chat settings directly within the voice chat interface. The voice quality is generally just as good as with other AI chatbots.### Who It's For
NSFW content fans: Grok's datable AI companions, along with its generally lax guardrails, separate it from other chatbots.Social media searchers: If you want responses that consider what the general populace thinks, Grok automatically includes X posts as sources. That makes it the premier AI chatbot for community feedback.### Specs & Configurations

Buying Guide: The Best AI Chatbots for 2026
What Are AI Chatbots? #
‘AI chatbot’ is somewhat of an umbrella term. An AI chatbot can describe ChatGPT just as it can a customer service bot you talk to before reaching a human. We use the term here to refer to services built on top of large language models (LLMs). LLMs enable you to do everything from efficiently searching the web to having chats with what feels like an actual person.
What Is a Large Language Model? #
LLMs are, at their most basic level, artificial neural networks that companies train on massive quantities of data. Think of a large language model like a very complicated, very long equation that you can plug just about any request into and get a response from, whether that’s the answer to a question or a generated image. For example, GPT-5.6 is the LLM that powers OpenAI's ChatGPT.
What Can AI Chatbots Do? #
AI chatbots go far beyond simple question-and-answer text chats. In 2026, AI chatbots can complete tasks for you, such as adding ingredients to a virtual grocery cart, and serve as personal assistants that help organize your life. They can also build apps from scratch, write dozens of pages of research reports, and generate lifelike images and videos. If you prefer, you can interact with most chatbots by voice rather than text.
Some chatbots integrate with apps you already use to provide unique functionality, such as Copilot in Microsoft 365 and Gemini in Google Workspace. As an example, Gemini can answer questions based on your Gmail history. A new crop of AI web browsers goes all in on AI chatbot features, including AI agents, meaning you can take advantage of AI capabilities on every web page you visit.
How Much Do AI Chatbots Cost? #
All the chatbots we test have free versions. Paid plans usually range from $10 to $20 per month, depending on the chatbot, and almost every chatbot offers them. Many chatbot features are available for free, albeit with usage limits; however, you need to pay extra for certain features, such as integrating Copilot or Gemini across their respective app ecosystems.
What’s the Best Free AI Chatbot? #
Generally, Google Gemini is the best free chatbot. Gemini provides access to its latest models, including 3.7 Flash and Veo 3.1, along with deep research and voice chat features, all for free. You also get 15GB of cloud storage via Google Drive. Many other services put their most advanced models behind paywalls, while luxuries like cloud storage are rare, even on paid plans.
Are AI Chatbots Conscious? #
You can chat with an AI chatbot like you would a person, so some think chatbots are conscious, but they absolutely are not. An AI chatbot is akin to a video game character with different dialogue options. Our point is that chatbots are merely complex prompt-response machines, not sentient in any way. So, you can't have real relationships with them, nor can they truly be your friend or therapist.
Where Can You Learn More About AI? #
You can query any of the chatbots on this list to find information about how AI (or AI chatbots) works, but a number of more formal resources are available online for you to check out. Ironically, AI chatbots themselves aren't great at explaining how they work, so make sure you verify what they tell you with other sources.
Are Alexa or Siri AI Chatbots? #
Alexa and Siri are functionally AI chatbots in 2026, but they don't have the same breadth of features as the services on this list. For example, they lack agents, deep research capabilities, model selection options, and more. However, they do generate images, run on top of LLMs, and support free-flowing, organic conversations.
However, Alexa and Siri come with some caveats. Alexa's features aren't up to snuff with the competition, for example. And the bulk of Siri's AI features won't arrive until the fall, so we don't yet have a good sense of how well they work.
How Can You Tell If Something Is AI-Generated? #
The unfortunate answer is that you often simply cannot. Many online services attempt to analyze text to determine if it was generated by AI, but they are imperfect. Some quirks, such as a heavy reliance on em dashes, are hallmarks of AI generation, but just seeing an em dash isn't enough to tell if something is AI-generated. In general, we recommend sticking with sources you trust to avoid AI-generated content. If you want to know whether an image or video is AI-generated, we have tips and tricks for spotting both fake images and videos.
Are AI Chatbots Censored? #
Yes, every AI chatbot has some amount of censorship. This ranges significantly, though. For example, DeepSeek has some absolutely egregious censorship where it won’t talk about certain historical events, such as the Tiananmen Square massacre, to keep its responses in line with Chinese propaganda. Meanwhile, Grok is extremely permissive, allowing you to generate images and videos of real people.
Which AI Chatbot Allows Explicit Content? #
Of all the chatbots on this list, Grok is the only one that truly allows explicit content. You can use Grok to generate NSFW images and videos, as well as have explicit relationships with its virtual companions, such as the anime character Ani. That said, Grok isn't the best place on the internet for either AI companionship or porn, even though it’s the only full-service chatbot on this list to allow that. You're better off looking for a dedicated AI service if you primarily want to generate explicit content.
Can the Law Use AI Chats Against You? #
Yes, courts can and will use your conversations with chatbots against you, so don’t act as if you're anonymous. If you talk to a chatbot about committing a crime or mention crimes you committed, the law might compel AI companies to hand over your conversations. Even if you haven't committed a crime, you might end up in a lawsuit, and your conversations might come up.
How We Choose the Best AI Chatbots #
We focus on full-service web-based chatbots, rather than those that you can run locally on your computer. The latter requires a fairly significant time investment and relatively powerful hardware. We also exclude single-use chatbots that specialize in a particular use case at the expense of most others, such as AI companion chatbots.
To test AI chatbots, we provide each with a series of prompts and compare their responses, evaluating accuracy, consistency, complexity, and depth. Each chatbot is different, though, so we tailor our testing to the specific features it offers. That said, we generally evaluate AI chatbots based on their ability to perform complex reasoning, creative writing, deep research, file processing, image editing, image generation, video generation, voice chat, and web search.
Of course, it’s impossible to fully vet the scope of an AI chatbot. One person might have a niche use case related to their work, while another might have zero use for that same functionality. It would require an army of experts in every field to fully evaluate these tools, and even then, what works well one day might not the next after an update. That said, we notice clear differences in testing and routinely update our reviews as chatbots evolve. Keep in mind that our reviews are accurate as of their publication date.
What's the Best AI Chatbot for Image Generation? #
Among the many excellent AI image generators available, Gemini's Nano Banana Pro is the best in class. It creates incredibly lifelike visuals. Just keep in mind that you get limited access to it for free before Google switches you over to the original Nano Banana (which won our Technical Excellence award). ChatGPT's image generation model is similarly excellent and doesn't require a paid plan. The bottom line is that you can generate a ton of high-quality AI images without spending a dime.
What's the Best AI Chatbot for Video Generation? #
You have many choices in AI video generators, but Gemini's Vero 3.1 is the clear winner in terms of quality. Sora 2 was competitive until OpenAI shut it down. Just keep in mind that AI video generation is much more difficult to do for free compared with AI image generation. Expect to spend some cash if you want to dial in the perfect video.
What's the Best AI Chatbot for NSFW Content? #
You can find plenty of NSFW AI image generators and NSFW AI video generators online, but Grok and Kindroid excel at both tasks. It's possible to generate NSFW AI images easily for free, but you will likely need to pay to create NSFW AI videos. Alternatively, you can explore local options that are completely free and entirely private, such as FramePack for video generation and RuinedFooocus for image generation.
