ChatGPT and Claude in a nutshell

ChatGPT, made by OpenAI, is the assistant that kicked off the consumer generative AI wave. It has grown into a full toolbox: chat, web search, file analysis, image creation, voice mode, memory, projects, connected apps and deep research.

Claude, made by Anthropic, a company founded by former OpenAI team members, puts the emphasis on reliability, safety and answer quality. It’s available on the web, on desktop and on mobile. Claude also offers web search, file analysis, projects, connections to other services and deep research (Research, limited to the paid Pro, Max, Team and Enterprise plans), but it doesn’t generate images the way ChatGPT does.

Both run on model families that get updated regularly, with fast versions for everyday use and more powerful ones for complex tasks.

Writing: Claude’s biggest strength

This is where Claude stands out most often. In my experience, as for many users, Claude writes more naturally: fewer canned phrases, smoother transitions, a tone that adapts closely to what you ask for. For a long piece (an article, a tricky letter, a speech, a short story), the difference often shows from the very first draft.

ChatGPT is still very good at writing, especially when it comes to following a specific format (table, outline, list, word count) or quickly producing several variations. With good instructions, it can sound just as natural. I show you how in my article on how to write a good ChatGPT prompt.

To compare for yourself, give them the exact same instructions:

Write a 150-word email telling my team that leadership has canceled the project we’ve worked on for six months. Keep the tone honest and kind, skip the corporate speak, and end on a positive note about what comes next.

Document analysis: both excel

Both assistants can read PDFs, Word documents, spreadsheets and images, then answer your questions, summarize or pull out information.

Claude has long been known for handling very long documents accurately: contracts, reports, entire books. It’s especially good at cross-referencing several documents and quoting the relevant passages.

ChatGPT is also very capable, with an edge in data analysis: it can run calculations, make charts and generate files for you to download (spreadsheets, slide decks). My tutorial on using ChatGPT with a PDF covers everything it can do.

My advice: for reading, understanding and summarizing a long text, they’re on par, with a slight style edge for Claude. For crunching numbers and producing tables or charts, ChatGPT is often more convenient.

Web search

Both assistants can search the web and cite their sources. Both also offer a deep research mode that can dig into a topic for several minutes and produce a detailed report.

In practice, ChatGPT often triggers a search automatically as soon as a question is about current events; with Claude, web search has to be turned on in the tools, and once it is, Claude can use it for questions that benefit from up-to-date info. Regular web search is also available on the free version, while Research is reserved for paid plans. Either way, fact-checking habits are still a must: I cover them in my guide to using ChatGPT to search the web.

Images, voice and multimedia

This is where ChatGPT clearly takes the lead.

• Images: ChatGPT creates and edits images right in the chat (see my guide to creating images with ChatGPT). Claude can analyze images you send it, but it doesn’t generate them.
• Voice: ChatGPT’s voice mode is very polished, with natural, fluid conversations. Claude has a voice mode, still in beta, on mobile, web and desktop, in several languages: the experience isn’t as refined as ChatGPT’s.

So if you need visuals, ChatGPT is the obvious choice, or you’ll have to pair Claude with a separate image tool.

Code and technical work

Many developers prefer Claude. Its models are highly regarded for writing, explaining and fixing code, and Anthropic offers dedicated developer tools that can work directly inside a software project.

ChatGPT is excellent at programming too, with dedicated tools like Codex and advanced reasoning modes on its paid plans.

For occasional use (an Excel formula, a small script, making sense of an error message), either one will do the job perfectly. If you code every day, it’s worth testing both on your own projects: preferences are very personal.

Organization, projects and personalization

ChatGPT has the richest personalization ecosystem: memory for important details, custom instructions, projects and Plugins, which combine reusable instructions with connected apps. Existing custom GPTs still work, but personal accounts can no longer create new ones as of September 2026. I explain it all in my article on ChatGPT memory.

Claude offers projects to group chats, documents and instructions around a single topic, profile preferences, styles to shape its answers, project instructions, a memory that keeps useful details from your conversations and, on paid plans, search across your past chats. It can also create artifacts: documents, mini-apps or visualizations shown next to the chat that you can edit and share.

Pricing and limits

Both assistants offer a free version and several subscription tiers.

• ChatGPT: free, Go ($8 a month), Plus ($20 a month), Pro and business plans. I break down the differences in my articles on free ChatGPT and ChatGPT Plus.
• Claude: free, Pro ($20 per month on the web, before tax; also $20 a month through the US App Store), Max 5x ($100 per month) and Max 20x ($200 per month) for heavy use, plus team plans. In the US, Claude Pro costs the same $20 a month on the web and through the App Store.

One thing to watch: on free Claude, you can hit the limits quickly with long documents or tool use, since they depend on conversation length, files and server load. Compare both based on how you’ll really use them.

Privacy and safety

Anthropic has built part of its reputation on the safety and caution of its models. Claude tends to flag its uncertainty more clearly and to decline certain sensitive requests.

On the data side, both services let you choose whether your conversations can be used to improve their models, and let you delete your history. Settings and retention periods change over time, so take a few minutes to review them in each service’s privacy settings.

Whichever assistant you use, the rule is the same: no passwords, no banking details, no sensitive health information in your chats.

Three hands-on tests to make up your mind

Rather than relying on online rankings, which change with every new release, I recommend running these three simple tests. They take about twenty minutes and will teach you more than any comparison article.

Test #1: rewrite something you wrote

Take something you wrote recently (an important email, a personal bio, a social media post) and ask both assistants to improve it without changing the substance.

Here’s something I wrote: [text]. Make it clearer and more enjoyable to read while keeping my voice. Then explain in three bullet points what you changed and why.

Pay special attention to which one best respects your voice. That’s often where preferences take shape.

Test #2: quiz a long document

Pick a PDF of about thirty pages that you know well (a set of rules, a contract, a report). Ask both assistants the same three specific questions, including one whose answer is hidden in a detail near the end. See which one finds the right information and quotes the passage correctly.

Test #3: a task from your real life

Finally, give them a real task from your week: building a schedule, prepping for a meeting, comparing two offers, writing a delicate reply. It’s the most telling test, because it reflects exactly how you’ll use them.

Rate both answers on three criteria: accuracy, clarity and time saved. In most cases, a clear winner emerges for your needs, even though both are top-notch.

My verdict for your profile

You write a lot

Articles, reports, letters, content: Claude is often more pleasant for long, nuanced writing. It’s my go-to for proofreading or rewriting an important text.

You want one tool that does it all

Text, images, voice, search, files, custom assistants: ChatGPT is the most complete Swiss Army knife. If you can only keep one, it’s probably this one.

You analyze long documents

Contracts, studies, hefty files: both are excellent. Claude writes very clear summaries; ChatGPT is handier for turning data into tables or charts.

You code

Test both, but Claude is very often named among developers’ favorites.

You want to stick with a free version

Both free versions are useful, but with free Claude you can hit the limits fast on long documents. My advice: free ChatGPT for everyday use, free Claude for a second opinion on an important piece of writing.

Using them together

Lots of power users combine the two, and it’s a great strategy. Here’s how I often do it:

1. ChatGPT for research, ideas and structure (with web search turned on).
2. Claude for writing or rewriting the final text.
3. ChatGPT to create the illustration that goes with the content.
4. Either one for a critical review of the result.

Here’s a text written by another AI assistant. Review it like a demanding editor: point out errors, vague passages, repetition and overly generic phrasing, then suggest an improved version.

Having one assistant review the other’s work is also a great way to catch mistakes.
