Claude 2 is an AI assistant launched by Anthropic in July 2023. It is considered a competitor of ChatGPT and is at the same level as ChatGPT 3.5.

Claude Pro is a paid version launched by Anthropic on September 7, 2023, priced at $20 a month, which is obviously based on the price of ChatGPT PLUS.

Claude 2 and Claude Pro are only open to the United States and the United Kingdom, and must be accessed using American and British IPs. The website address is: claude.ai . Currently, there is only a web version and no APP.

Advantages of Claude.ai: longer context window, faster output speed, complex reasoning capabilities, etc. Big VPS players find that the text generated by Claude.ai is fluent and the language is vivid, while the language of ChatGPT is relatively more formal and written. This mainly stems from their different training data and model designs. Claude.ai may be trained on more spoken dialogue data, and the language style will be closer to daily spoken language. ChatGPT is trained on a large amount of written corpus, and the language style is more formal.

Claude Pro offers:

  • Usage is 5 times that of the free tier, allowing you to send more messages
  • Prioritize access to Claude.ai during high traffic periods
  • Get early access to new features to help you get the most out of Claude

Obviously, this also refers to the wording of ChatGPT Plus, which is three lines.

Claude’s registration is very simple (use an American or British IP address). The registration website is: claude.ai . You can register using email + password, or you can use the quick login: Continue with Google. Netizens who have used ChatGPT should be familiar with this. .

When it comes to verifying email addresses, ChatGPT sends a verification link, while Claude uses a verification code. There is finally a difference.

Claude also needs to verify the phone number, which only supports phone numbers in the United States, the United Kingdom, and British overseas territories. Google Voice cannot be used, but Ultra Mobile PayGo , Giffgaff , and Tello phone cards can be used. Of course, you can also use the code receiving website sms-activate.org . There are tutorials on the use of this platform: SMS verification code platform .

The number in the picture is the number of the British calling card Giffgaf f.

Claude’s interface is very simple, you can directly upload PDF files and let it help you summarize. As shown in the picture:

In addition to PDF files, it also supports txt and csv files. Up to 5 files can be uploaded at one time, each file can be up to 10M. It can help you summarize and process data, which is very useful.

A very familiar payment interface, like ChatGPT, also uses Stripe’s payment interface, as shown in the figure:

You can pay with a virtual credit card. I use vvacard virtual credit card . Card segment: 553437. Deduction record:

If you feel that Claude Pro is not worth the price, or you will not use it later, you can cancel the subscription to avoid chargebacks. After cancellation, you can continue to use it until the next deduction cycle, as shown in the figure:

Proper use of Claude Pro can improve work efficiency in various tasks, such as summarizing research papers, querying contract details, optimizing coding, etc., thus giving you more time to fish.

I have to say that Claude Pro is really powerful, and it actually understands what “catching fish” means. As shown in the picture:

This is consistent with Claude’s promotion of itself as an “artificial intelligence safety and research company” dedicated to answering questions in a safe and helpful way.

Below is the performance of ChatGPT:

Although ChatGPT did not refuse to answer like Claude, which seems a bit unethical, the rewriting of ChatGPT is still possible, so I adopted its expression.
