The Best AI Chatbots in 2026: ChatGPT, Claude, Gemini and 5 More Compared

There are more AI chatbots than ever, and most of them are free to start. The differences that matter for everyday use are not benchmark scores but simpler things: what the free plan includes, what $20 a month adds, where the assistant lives on your phone or computer, and what it is particularly good at. This guide compares the eight that most people choose between, using each company’s own pricing pages where they publish them, checked in October 2026.

1. ChatGPT — the best all-rounder

ChatGPT is still the default for a reason: it writes, explains, summarises, codes, makes images, talks by voice and searches the web, all in one app. According to OpenAI’s pricing page, the free plan now offers unlimited text chats with GPT-6 (subject to abuse guardrails), with limited uploads, image creation, voice chats and deep research.

• Go, $5/month: more messages with tools, uploads, images and voice, and longer memory. OpenAI notes this plan may include ads.
• Plus, $20/month: advanced reasoning models with GPT-6, projects, scheduled tasks, custom GPTs and expanded limits. This is the upgrade most people should compare against Free.
• Pro, from $100/month: Pro reasoning powered by GPT-6 Astra, Dot (an always-on agent) and the highest limits. Only for all-day professional use.

Choose it if you want one assistant for everything. Our ChatGPT plans guide goes deeper on which tier to pick.

2. Claude — best for writing and long documents

Claude, from Anthropic, is the chatbot many writers, students and programmers prefer. It handles long documents well, its writing usually needs less editing, and it is strong at code. Anthropic’s pricing page lists web search, file creation, code execution, memory and projects on the free plan, which uses the Sonnet and Haiku models. Free users now get Claude Sonnet 5.5, released on 28 September 2026.

• Pro, $20/month ($17/month billed yearly): adds the stronger Opus model, Claude Code, Research and unlimited projects.
• Max, from $100/month: five or twenty times the Pro usage, for heavy daily use.

The catch: Claude does not create images. Choose it if you mostly write, edit, analyse documents or code. See Claude vs ChatGPT for a head-to-head.

3. Gemini — best free plan for Google users

Gemini is Google’s assistant, and it lives where many people already are: in Android phones, Gmail, Docs and Chrome. The free plan includes image generation, Deep Research, Gemini Live voice conversations and Canvas, with 15 GB of Google storage. Paid plans are sold as Google AI: AI Plus ($4.99/month in the US) doubles the free limits and adds video generation and 400 GB of storage; AI Pro ($19.99/month) gives four times the free limits, access to Gemini 3.8 Flash and 3.1 Pro, and 5 TB of storage; AI Ultra starts at $99.99/month.

Google’s next big model, Gemini 4 Argon, was announced on 30 September but is not yet in the Gemini app; Google says AI Ultra subscribers will be among the first to get it. Choose Gemini if you live in Google’s apps or want the most generous free plan. Details: Is Gemini free? Google AI plans explained, and Gemini vs ChatGPT.

4. Microsoft Copilot — best if you live in Windows and Office

Copilot is built into Windows, the Edge browser and Microsoft’s apps, and has its own app and website. The free version answers questions, searches the web and makes images. For more, Microsoft stopped selling the standalone Copilot Pro plan to new customers and now bundles its premium Copilot features into Microsoft 365 Premium at $19.99/month, which also includes the Office apps and cloud storage, according to pricing guides. Business use is licensed separately.

Choose it if you already pay for Microsoft 365 or want an assistant inside Word, Excel and Outlook. Compare it with Claude in Copilot vs Claude.

5. Perplexity — best for research with sources

Perplexity works more like a search engine that writes the answer for you: every reply comes with numbered citations you can click and check. That makes it the better choice when the question is “what is actually true, and who says so?” Perplexity has a free plan, and Pro costs $20/month or $200/year, according to pricing reviews of its official plans. It also makes the Comet web browser.

Choose it if you research topics, compare products or need sources for school or work. See our Perplexity Pro review and Comet browser review.

6. Grok — best for live news and X

Grok, from Elon Musk’s xAI, is built into X (formerly Twitter) and also has its own app. Its distinguishing feature is access to live posts on X, which makes it quick on breaking news and trends, and it takes a looser, more opinionated tone than most rivals. There is a limited free tier; SuperGrok costs $30/month, according to pricing reports, with cheaper and pricier tiers around it.

Choose it if you spend time on X and want answers tied to what people are saying right now. More in ChatGPT vs Grok.

7. Muse — the new one that does tasks for you

Meta launched Muse on 8 September 2026, and it quickly became the top free app on Apple’s US App Store, ahead of ChatGPT. It is different from a classic chatbot: Meta describes it as a personal agent that “actually does the work”, such as sending emails, booking travel and filling in forms, asking for your approval before sensitive steps like sending or buying. It runs on Meta’s Muse Spark models and is rolling out in the US on iOS, Android and muse.ai.

Meta says Muse is free for most of what people need, with paid plans for more; reports put them at $20 and $100 a month. Think carefully before connecting it to your email, calendar and payments: an agent that acts for you needs more trust than one that only answers questions. Meta says Muse never sees your passwords or payment details. For making pictures with Meta’s tools, see our Meta AI image generator guide.

8. DeepSeek — best free option for maths and code

DeepSeek, from China, offers a free chatbot on the web and in its app, and its models are strong at maths, reasoning and code for the money. There is no consumer subscription; developers pay per use through its API. The trade-off is privacy: DeepSeek’s privacy policy says it stores data on servers in China, which some companies and governments do not allow for work use. Choose it if you want a capable free assistant for technical questions and are comfortable with that. Background: DeepSeek explained and DeepSeek vs ChatGPT.

Which AI chatbot should you use?

• You want one app that does everything: ChatGPT. Start free; Plus is the upgrade worth comparing.
• You write a lot or work with long documents: Claude.
• You use an Android phone, Gmail or Google Docs: Gemini.
• You use Windows and Office every day: Copilot.
• You need sources you can check: Perplexity.
• You follow news on X: Grok.
• You want an assistant to carry out tasks: try Muse, carefully.
• You want something free for maths or code: DeepSeek, keeping the privacy trade-off in mind.

You do not have to pick just one. Most free plans are generous enough to keep two: for example ChatGPT or Gemini for everyday questions, plus Claude for writing or Perplexity for research. If none of these suit you, our list of ChatGPT alternatives includes options that run privately on your own computer.

Whatever you choose, AI chatbots still make mistakes, sometimes confidently. Check anything important, such as health, money or legal questions, against a reliable source.
