What it is

Claude is an AI assistant made by Anthropic. It is known for handling long documents well, writing in a clear and natural style, and helping with code. You can use it in a browser, desktop app or mobile app, and developers can also use it through coding tools.

Best for

• Reading and summarising long reports, contracts and policies you upload
• Careful writing: proposals, documentation, explanations
• Comparing documents and pulling out key points with quotes
• Coding help: explaining code, debugging, writing tests and reviewing changes
• Step-by-step analysis of a problem before deciding

How to start

1. Go to the official website or app and create an account.
2. Review the privacy and data settings.
3. For long documents, upload the file and ask specific questions, for example "List every deadline with the exact line it comes from."

Example prompts

Here is our travel policy. Based only on this document, can an employee
claim a taxi at 11 pm? Quote the line you rely on.

Review this C# method for bugs and edge cases. List issues first, then
suggest a fix. Do not change its public signature. [paste code]

There is a free plan with usage limits. Paid plans give more usage, more capable models and extra features for individuals and teams. Check Anthropic's official site for current plans.

Watch out for

• Like every AI tool, it can make mistakes. Check facts, numbers and code.
• Do not upload confidential documents to a personal account unless your company allows it.
• Never paste secrets such as passwords, API keys or connection strings.

Our tip

For long documents, ask Claude to quote the exact line behind each answer. It makes checking quick and catches misreadings early. For coding, see our course AI for Developers.
