Which AI is the best?

There is no single winner. ChatGPT is the best all-rounder, Claude writes the best, Gemini fits Google users, Copilot fits Microsoft users, and Perplexity is best for research with sources. Pick by task, not by hype.

Do I need to pay for any of them?

No. Every tool above has a free tier that covers normal everyday use. Pay only if you hit the free limits regularly, which most people never do.

Can I use more than one?

Yes, and that is the smart move. Use Perplexity for research, then Claude or ChatGPT to help you write it up. Free tiers make this cost nothing.

Do these prices change?

Constantly. AI pricing moves every few months. Check the official site before paying for anything, and never trust a price in an article, including this one, without checking.

The short version

All five have free tiers that cover normal use. None of them is the best at everything. ChatGPT is the best all-rounder. Claude writes the best. Gemini fits people who live in Gmail and Docs. Copilot fits people who live in Word and Outlook. Perplexity is the one to use when you want sources. Start free, pick by task, and pay only if you hit a free limit regularly.

ChatGPT by OpenAI

The one most people mean when they say AI chatbot. Type a question, get an answer. The free tier handles everyday use.

Good at

General questions, drafting emails and documents, brainstorming, explaining things simply. The most third-party integrations.

Honest limits

The free tier caps the stronger models. Like all chatbots, it invents facts confidently, so verify anything important.

Cost

Free tier available. Plus is $20 a month. Prices change, check openai.com before paying.

Claude by Anthropic

A chatbot known for careful, well-written answers. Strong on long documents and nuanced writing.

Good at

Writing help, summarizing long documents, working through complicated questions step by step.

Honest limits

Free tier has daily message caps. No built-in web search on the free tier, so it cannot check current facts itself.

Cost

Free tier available. Pro is $20 a month. Prices change, check anthropic.com before paying.

Gemini by Google

Google's chatbot, woven into Gmail, Docs, and Google Search. If you live in Google products, it meets you there.

Good at

Summarizing emails and documents in Gmail and Docs, questions where Google's search index helps, generous free tier.

Honest limits

Tied to a Google account, which means Google sees the chats. Verify important facts like with any chatbot.

Cost

Free tier available. Google AI Pro is $19.99 a month. Prices change, check the Google One page before paying.

Microsoft Copilot by Microsoft

The chatbot built into Windows, Edge, and Microsoft 365. If you use Word and Outlook all day, it is already nearby.

Good at

Summarizing Word documents, drafting Outlook emails, quick answers inside Windows and Edge.

Honest limits

The most useful features sit behind a Microsoft 365 subscription. As a standalone chatbot it is less capable than the others.

Cost

Basic version free. Full features need Microsoft 365. Prices change, check microsoft.com before paying.

Perplexity by Perplexity AI

Less a chatbot, more an answer engine. It searches the web and answers with cited sources you can click.

Good at

Research questions where you want sources. Every answer links where it came from, so checking is fast.

Honest limits

The free tier limits advanced searches per day. It is a research tool first, a weaker brainstorming partner than the chatbots.

Cost

Free tier available. Pro is around $20 a month. Prices change, check perplexity.ai before paying.

The one rule

Whichever you pick, the rule from the mistakes page still applies: verify anything important against the original source. The chatbot with the best answer is still a chatbot, and chatbots invent facts.
