ChatGPT vs Claude vs Gemini: Which One Should You Actually Use?

Welcome to this Issue of the ElevateX Newsletter. Each week, one practical AI skill to help you get ahead. Takes about 4 minutes to read.

Ask anyone which AI tool they use and the answer is almost always ChatGPT. Fair enough. It was the first, it is the most popular, and it does a lot of things well.

But here is something most people do not realise: ChatGPT is not always the best tool for what you are trying to do. There are several other AI tools out there, but two worth paying attention to are Claude (by Anthropic) and Gemini (by Google). Each one is genuinely better at specific tasks.

This is not a technical comparison with benchmarks and scores. I use all three of these tools regularly in my own work, and this is based purely on my experience. A simple, practical guide: which tool to open for which task. That is it.

ChatGPT is the most versatile of the three. It handles almost anything you throw at it - writing, coding, brainstorming, summarising, translating. If you only want to use one AI tool, this is the safe choice.

What it does best: quick answers, general writing, brainstorming ideas, creating outlines, explaining concepts in simple language. It also has a code interpreter that can run code and generate charts, which is useful for data-related assignments.

Where it falls short: when you give it a very long document to work with (say, a 50-page PDF), it tends to lose track of details in the middle. Its writing can also sound a bit generic and over-polished, especially for longer pieces. And it is known to hallucinate - meaning it will give you an answer that sounds perfect and confident but is actually made up. Always verify important facts.

Best for: brainstorming, quick research, explaining concepts, creating outlines, first drafts of emails and cover letters.

Claude is built by Anthropic and it is genuinely different from ChatGPT in ways that matter if you do a lot of reading, writing, or working with long documents.

The biggest advantage is its context window. Claude can process much longer documents than ChatGPT without losing the thread. If you need to upload a 40-page textbook chapter and ask specific questions about it, Claude handles that significantly better.

It also writes more naturally. If you have ever felt that ChatGPT's writing sounds a bit robotic or uses too many buzzwords, Claude's output tends to feel more human. It follows instructions more carefully and produces cleaner, more thoughtful text.

Where it falls short: it does not have built-in web search on the free tier, so it cannot look up current information for you the way ChatGPT can. It is also more conservative - it will sometimes refuse to help with things that ChatGPT would handle without hesitation.

Best for: working with long documents, writing essays and reports, refining your resume language, getting detailed feedback on your work, and coding (especially debugging).

Gemini is Google's AI and its biggest advantage is that it lives inside the Google ecosystem. If you use Gmail, Google Docs, Google Drive, and Google Search every day (and most of us do), Gemini fits into your workflow more naturally than the others.

It is also the fastest of the three. Responses come back noticeably quicker, which matters when you are working through a long study session and asking lots of questions. Another underrated feature: Gemini can search and summarise YouTube videos. If you are trying to find the key points from a 45-minute lecture or tutorial without watching the whole thing, Gemini handles that really well.

The free tier is the most generous. You get access to capable models without paying, which is a real advantage if you are not ready to spend on a subscription yet.

Where it falls short: it can be inconsistent. Sometimes you ask the same question twice and get noticeably different answers. The writing quality is not as polished as Claude, and for complex coding problems it is not as reliable as ChatGPT or Claude.

Best for: quick research with web access, summarising content from Google Drive, searching and summarising YouTube videos, working within Google Workspace, and when you need speed over depth.

Here are my recommendations based on the time I have spent using different AI tools.

Writing a resume or cover letter? Start with Claude. It writes more naturally and follows formatting instructions better. Then run it through ChatGPT for a second opinion.

Preparing for an interview? Use ChatGPT. Ask it to roleplay as an interviewer for your target role. It is the best at back-and-forth conversation.

Studying from a long PDF or textbook? Use Claude. Upload the document and ask specific questions. It will not lose context halfway through. And yes, you can simply click a picture of your textbook pages and upload in Claude; it does a great job reading text from pictures.

Quick research or fact-checking? Use Gemini. It has built-in web search and pulls up current information fast.

Coding a project? Start with Claude for writing and debugging code. Use ChatGPT if you need to run code and see output. Use Gemini if you are working with Google Cloud or Firebase.

The real answer is: use more than one. They are all free to try. The people who will have an edge in the job market are not the ones who only know ChatGPT. They are the ones who know when to use which tool.

Pick one task you normally do in ChatGPT. Maybe summarising notes, or writing an email, or preparing for an interview. Do the exact same task in Claude and in Gemini. Compare the outputs side by side. You will immediately see the difference, and you will start making smarter choices about which tool to reach for.

That is it. Three tools, different strengths. Know when to use each one and you are already ahead of most people.

If you have a specific use case and you are not sure which AI tool would work best for it, write back to me. I will try my best to point you in the right direction.

Until next week,
