Core Capabilities
Seven common Claude Chat uses, each with a short example you can try at claude.ai.
Writing and editing
Draft, rewrite, and polish written content — from a quick email to a full essay or creative story.
- Drafting emails, cover letters, and professional messages
- Writing essays, reports, and blog posts in a chosen tone
- Creative writing — stories, scripts, poems, and dialogue
- Editing for clarity, grammar, tone, or length
Subject: Following up on our project proposal
Hi [Name], I wanted to check in on the proposal I sent last week. I'd be happy to answer any questions or adjust the scope if needed. Please let me know if you'd like to discuss further.
Best regards, [Your name]
Summarization
Condense long documents, articles, or pasted text into clear key points without losing what matters.
- Summarizing articles, PDFs, and research papers
- Extracting action items from meeting notes
- Creating executive summaries of long reports
- Bullet-point or paragraph summaries in your preferred length
- The study found remote work increased productivity by 13% on average across 500 companies.
- Employee satisfaction rose with flexible hours, but communication gaps remained a challenge.
- Companies that invested in async tools saw the strongest long-term results.
Q&A and research
Ask factual questions, go deeper on a topic, or get analytical explanations broken into shorter answers.
- Answering factual and conceptual questions
- Explaining how things work — science, history, technology
- Comparing options and weighing trade-offs
- Analytical questions that need structured reasoning
HTTP sends data in plain text. HTTPS encrypts it using TLS, so passwords and personal data cannot be read in transit.
For websites, HTTPS is essential — browsers mark HTTP sites as "Not Secure," and search engines favour HTTPS pages. Any site that handles logins or payments should use HTTPS.
Brainstorming
Generate ideas, compare options, and sketch outlines or plans.
- Generating ideas for projects, products, or content
- Building outlines for essays, presentations, or reports
- Exploring pros and cons of different approaches
- Challenging your ideas with counterarguments
- "Python in 10 Minutes" — A zero-to-first-program walkthrough for absolute beginners.
- "5 Mistakes Every New Python Coder Makes" — Common pitfalls and how to avoid them.
- "Why Python Is the Best First Language" — Comparing Python to JavaScript and Java for newcomers.
- "Build a To-Do App in Python" — A hands-on mini-project tutorial.
- "Reading Python Error Messages" — How to understand and fix common errors.
Math and reasoning
Solve maths problems step by step, work through logic puzzles, or verify your own calculations.
- Arithmetic, algebra, and word problems explained step by step
- Logic puzzles and reasoning challenges
- Checking your work and spotting errors in calculations
- Breaking complex problems into smaller steps
Step 1: Notebooks → 3 × $4 = $12
Step 2: Pens → 5 × $2 = $10
Step 3: Total → $12 + $10 = $22
Maria spent $22 in total.
Code help
Get help explaining, writing, and debugging code. Paste a snippet and describe the problem — no full project access needed.
- Explaining what a piece of code does in plain English
- Writing functions, scripts, or small programs from a description
- Debugging errors when you paste the code and error message
- Refactoring or improving code you paste into the chat
Python lists are zero-indexed — valid indices for a 3-item list are 0, 1, and 2. Index 3 does not exist.
Translation and language
Work across multiple languages — translate text, adjust tone, or get help with grammar and phrasing.
- Translating between dozens of languages
- Adjusting tone — formal, casual, technical, or friendly
- Explaining idioms, grammar, and cultural nuance
- Rewriting the same message for different audiences
"Merci pour votre patience. Nous vous enverrons le rapport mis à jour d'ici vendredi."
The phrasing uses the formal "vous" form, which suits professional correspondence.
Refining any response
Include context in your prompts — audience, length, tone, and format. You can also refine in the same chat:
- “Make it shorter.”
- “Change the tone to more formal.”
- “Try again with more detail on the second point.”
Before you continue
- Claude handles writing, summaries, Q&A, brainstorming, maths, code, and translation.
- State audience, format, and length in your first message.
- Follow up in the same chat to refine tone, length, or detail.
- Next lesson: upload files and ask questions about them.
What's Next
File & Document Handling — upload PDFs, Word docs, spreadsheets, and images, then ask questions about them.
