Claude ChatLesson 2

Core Capabilities

Seven common Claude Chat uses, each with a short example you can try at claude.ai.

What Claude Chat can do

Unlike Claude Code, which reads and edits files in your project, Claude Chat works entirely through messages. You type a request, Claude responds, and you refine from there. Open claude.ai, start a chat, and type your request.

Tip: Be specific about format, length, and audience. A prompt like "Write a 3-paragraph report summary for a busy manager" will get a much better result than "Summarize this."

Summarization

Condense long documents, articles, or pasted text into clear key points — saving time 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

C
  • The study found that remote work increased productivity by 13% on average across 500 companies.
  • Employee satisfaction rose when flexible hours were offered, but communication gaps remained a challenge.
  • Companies that invested in async tools saw the strongest long-term results.
Example — summarizing a pasted article
🔍03

Q&A and Research

Ask factual questions, go deeper on a topic, or get analytical explanations — Claude breaks complex subjects into shorter, clearer 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

What is the difference between HTTP and HTTPS, and why does it matter for websites?
C

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.

Example — asking an analytical question
💡04

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

🧮05

Math & Reasoning

Solve maths problems step by step, work through logic puzzles, or verify your own calculations — Claude shows its working so you can follow along.

  • ✓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, manageable steps
claude.ai
A shop sells notebooks for $4 each and pens for $2 each. Maria bought 3 notebooks and 5 pens. How much did she spend? Show your working.
C

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 — without Claude needing access to your full project. Paste a snippet and describe the problem.

  • ✓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
claude.ai
I get "IndexError: list index out of range" on this code: items = ["a", "b", "c"] print(items[3]) What is wrong?
C

Python lists are zero-indexed — valid indices for a 3-item list are 0, 1, and 2. Index 3 does not exist.

# Fix: use index 2 for the last item
print(items[2]) # "c"
Example — debugging a Python snippet (no file access needed)
🌐07

Translation & Language

Work across multiple languages — translate text, adjust tone for different audiences, or get help with grammar and phrasing in any language.

  • ✓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
claude.ai
Translate this to French, keeping a warm and professional tone: "Thank you for your patience. We will send the updated report by Friday."
C

"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.

Example — translating with tone guidance
Summary: Include context in your prompts — audience, length, tone, and format. You can say "make it shorter," "change the tone," or "try again with more detail" to refine any response.
