What is Claude?

Claude is Anthropic's chat program. People search for it next to ChatGPT and Gemini. The job of all three is the same: you write, and a model writes back.

People pick it to have a long text read in one place and to have code explained. It works for a short question too. The difference is the company behind the name and the model that is open that week.

The account is separate. Signing in to ChatGPT or Google does not open Claude. There is a free side and a paid side. When the limit is full, the answer stops or gets shorter.

This one is wrong too. A long answer can sound right and still hold one false fact in the middle. Do not take a contract, a law, or a medical text as it stands. Read the code.

• To pick one of the three names, get used to one first. Do not mix all of them on the same day.
• Give a long text in parts. A very large paste in one go can be cut off.
• If you say "three sentences" or "one list", the answer comes in that size.
• For code, write the file name and what failed. A bare "fix it" is too little.
• Do not paste company documents or customer names.
• Checking the bottom of the answer is your job. The model does not always say its own mistake.
