Almost every week a new AI tool makes the news, and it can feel like you need to keep up with all of them. In practice, the big platforms are quite similar: you type a question, the AI answers, and you ask follow-ups.
What actually differs is what each one is best at, what it connects to, and how much it costs. This guide walks through the major platforms one by one, so you can pick one or two and ignore the rest.
ChatGPT (OpenAI)
ChatGPT is the tool most people mean when they say “AI”. It is good at general questions, writing and rewriting text, explaining things step by step, and working with files or images you upload.
The free version is enough for everyday use. Paid plans add stronger models, longer memory and image generation, but you should not pay for those until you hit a real limit.
Claude (Anthropic)
Claude is known for careful, well-written answers and for handling long documents well — you can paste in an entire report or a long email thread and ask for a summary.
It works very similarly to ChatGPT, so if you already use one, trying the other will feel familiar. The free version is solid; paid plans exist for heavier use.
Gemini (Google)
Gemini is Google's AI, and its main advantage is connection: it lives inside Gmail, Google Docs and Android, so it can help where your documents already are.
If you use Gmail and Google Drive daily, Gemini is the natural first choice — you get it without opening a separate app. The quality of answers is in the same league as ChatGPT and Claude.
Copilot (Microsoft)
Copilot is Microsoft's AI, built into Windows and Microsoft 365 (Word, Excel, Outlook). On Windows 11 it is already on your taskbar, waiting to help.
The free Copilot that comes with Windows is good for quick questions. The paid versions that write into Word and Excel make sense mainly for office work — do not buy them for home use without trying the free one first.
Perplexity
Perplexity behaves less like a chatbot and more like a search engine with an AI on top. Every answer comes with links to the sources it used, so you can check the facts.
This makes it the best pick when you need current, verifiable information — news, prices, product comparisons — rather than writing or brainstorming.
Meta AI
Meta AI lives inside WhatsApp, Instagram and Facebook. You chat with it where you already chat with people, which is convenient, and it is free.
It is fine for quick questions and ideas. For serious work with documents or long, careful answers, the dedicated platforms above are stronger.
Mistral
Mistral is a European platform that offers both a chat tool and a privacy-focused option. It is a good example of an alternative, but for most home users it does not offer a clear advantage over the tools above.
Worth knowing it exists, and worth trying if data location inside the EU matters to you.
How to actually choose
- Do not open a new account for every tool. Pick one to start with: ChatGPT or Claude for general help, Gemini if you live in Gmail, Copilot if Windows is your daily tool.
- Use the free version first. Every platform has one, and for everyday questions free is enough.
- Match the tool to the job: Perplexity for checking facts, a chatbot for writing and explaining, and the one built into your apps (Gemini or Copilot) for work inside documents.
- Never share passwords, ID numbers or card details with any AI. No real assistant needs them.
- Treat answers as a first draft, not the final word — especially for numbers, laws and medical or money advice.
The honest summary: they are more alike than different. Start with one free tool, learn to ask good questions, and switch later only if you hit a wall.
