How to Use Claude AI: The Key Takeaways

Claude works like ChatGPT or Gemini: create a free account on claude.ai, then type your request in the text box like you would with a colleague.
Claude's free version limits the number of messages sent over a given period; the exact quota varies and changes, so it's best to check it directly on the official site before planning heavy use.
Claude stands out mainly for its ability to handle long documents and for a tone considered more natural in written texts; the basic interface stays close to other AI assistants.
Many users test Claude alongside ChatGPT rather than as a replacement, to compare answers on the same task.

If you're looking for how to use Claude AI, you've probably already used ChatGPT or another AI assistant and want to know what Claude does differently before spending time on it. This guide starts from that premise: rather than explaining what a conversational AI is, it focuses on getting hands-on and on what actually sets Claude apart day to day.

How Do You Access Claude and Ask Your First Question?

Go to claude.ai (browser, desktop, or mobile app) or a platform giving access to Claude like Ai-chatpro.
Create a free account with an email address.
Type your request in the text box, just as you would with a colleague: no special syntax needed.
Add a document if your request is about it (contract, report, transcript); Claude can analyze it directly.
Clarify your need with a follow-up sentence if the first answer is too general.

Test Claude Alongside Other AIs

Compare Claude to ChatGPT, Gemini, or Mistral on the same task, without switching tabs or subscriptions.

What Is Claude Actually Used For?

The most common uses are writing and rephrasing long texts, analyzing and summarizing large documents, reviewing code, and thinking through a complex topic where you want to weigh several angles. Claude isn't specialized in just one of these uses: its distinctive trait is staying coherent across long exchanges and large documents, where other models sometimes lose the thread.

Tip

To make the most of Claude's strength, don't summarize a document yourself before giving it to Claude: paste it in full (or upload it) and let Claude work on the complete version. It's on long documents that the difference from other AI assistants is clearest.

Claude Free: What Are the Limits?

Claude's free version lets you send a limited number of messages over a given period, enough to test the tool or for occasional use. For regular or professional use, a paid subscription removes this limit. On Ai-chatpro, the trial of free models (including Claude) is set at 3 messages every 24 hours, letting you compare Claude to other AIs before choosing a subscription.

What’s the difference between Claude and ChatGPT?

Both are chat assistants with similar use cases. Claude is often praised for its more natural tone in long texts and its ability to handle large documents; ChatGPT stands out with a broader ecosystem of features and integrations. You can find the full comparison at https://ai-chatpro.com/fr/blog/claude-vs-chatgpt.

What’s the limit of Claude’s free version?

The exact number of allowed messages on the free plan varies and may change; the best option is to check the current limit directly on claude.ai. On Ai-chatpro, the free trial is set to 3 messages every 24 hours per free model, including Claude.

Why do some users switch from ChatGPT to Claude?

The most common reason is the perceived quality of the written text (more natural tone, fewer repetitive phrases) and better handling of long documents. It’s not a one-size-fits-all replacement: many people use both side by side depending on the task.
